Vertical take-off and landing aircraft uses hydrogen-electric technology to complete landmark 523-mile flight. This Electric Air Taxi has Only One Byproduct: Water Vertical take-off and landing aircraft uses hydrogen-electric technology to complete landmark 523-mile flight. Cool Stuff Jul 29, 2025 On June 30, 2025 Joby Aviation, Inc., a company developing electric air taxis for commercial passenger service announced that its electric air taxi has completed a series of piloted, electric Vertical Take-Off and Landing (VTOL) wingborne flights in Dubai, marking the start of its commercial market readiness efforts in the region. These efforts will further develop Joby’s readiness in anticipation of carrying its first passengers in 2026 and marks a major step in the company’s three-pronged commercialization strategy: direct operations, aircraft sales, and regional partnerships. In July of 2024, Joby demonstrated its potential for emissions-free regional journeys. The company’s hydrogen-electric air taxi demonstrator had built on Joby’s successful battery-electric air taxi development program and demonstrated the potential for hydrogen to unlock emissions-free, regional journeys that didn’t require a runway. The hydrogen-electric program built on technology developed by Joby subsidiary H2FLY and was supported through Joby’s partnership with the U.S. Air Force’ Agility Prime program. The landmark test flight, believed to be the first forward flight of a vertical take-off and landing aircraft powered by liquid hydrogen had been completed using a converted Joby pre-production prototype battery-electric aircraft fitted with a liquid hydrogen fuel tank and fuel cell system. It landed with 10% of its hydrogen fuel load remaining. Jacob Wilson, (Acting) Branch Chief, AFWERX Agility Prime, said: "Agility Prime has been very supportive of hydrogen-powered aircraft development and testing as it aligns with the program’s goals to advance transformative vertical lift technologies and broader Department of Defense operational energy goals of energy substitution and diversification, and energy demand reduction.” All photos courtesy of Joby Aviation Joby’s hydrogen-electric demonstrator was part of the Company’s future technology program and was the result of several years of collaboration between a small team at Joby and H2FLY, Joby’s wholly-owned subsidiary based in Stuttgart, Germany. The converted aircraft previously completed more than 25,000 miles of testing as a battery-electric aircraft at Joby’s base in Marina, CA. Using the same airframe and overall architecture as Joby’s core, battery-electric aircraft, this demonstrator featured a liquid hydrogen fuel tank, designed and built by Joby, which stored up to 40 kilograms of liquid hydrogen, alongside a reduced mass of batteries. Hydrogen was fed into a fuel cell system, designed and built by H2FLY, to produce electricity, water, and heat. The electricity produced by the hydrogen fuel cell powered the six electric motors on the Joby aircraft, while the batteries provided additional power primarily during take-off and landing. As part of Joby’s wider commitment to leading the way on the development of new aviation technologies, it recently acquired Xwing Inc., an industry leader in the development of autonomous technology for aviation. Xwing has been flying autonomous aircraft since 2020, with 250 fully autonomous flights and more than 500 auto-landings completed to date, using the Superpilot software it developed in-house.

Rogue State turns to LightWave 11.5 3D software to conquer CG dragons for Dracano. LightWave 11.5 3D Software Used in Video Games Rogue State turns to LightWave 11.5 3D software to conquer CG dragons for Dracano. EE Staff Film and TV Jun 4, 2025 In Dracano, a volcanic eruption in the Pacific Northwest spews lava, steam and fire—along with eggs that hatch ancient, menacing, winged dragons that prey on man. Since similar volcanic eruptions in Russia, Japan, and other “Ring of Fire” regions are also releasing these menacing creatures into the world, scientists fear they are witnessing the start of a global dragon apocalypse. Set in contemporary times, this ambitious plotline depends upon the credibility of the dragon creatures and their appearance, movement, and interaction with people from a nearby U.S. military base who fight back. Three visual effects animators completed the movie’s 220 visual effects shots using LightWave 11.5, which advances the features, capabilities, and efficiency of the popular LightWave 3D modeling and animation system. “There is no other 3D animation software out there with the breadth of features and ease of use to allow us to handle all of these visual effects shots for Dracano, given the tight time and budget constraints,” said Scott Wheeler, visual effects supervisor for Dracano and president of Rogue State, a visual effects and post production boutique in Burbank, CA. In the fall of 2012, Rogue State worked closely with Los Angeles-based Remember Dreaming Productions to realize this fantasy/action adventure movie for Odyssey Entertainment in Australia. LightWave 11.5 was used to create all of the CG dragons, military vehicles, helicopters, and jets, as well as volcanic smoke, steam, and lava. It was also the primary tool for creating the 220 live action visual effects composites. LightWave 11.5 features like Genoma for character rigging, Soft Body Bullet Dynamics, and Motion Blur added to the Viewport Preview Renderer (VPR) system, and sped up the process and streamlined the workflow on complex effects shots by a factor of ten. Credit: LightWave Dragon The Genoma Potential Genoma is an intuitive character rigging system that jump-starts the 3D modeling process by providing instant rigging of legs, arms, fingers, wings, spines, and other body parts for biped, quadrupeds, and even exotic creatures, like dragons. While Genoma provides a head start in creating 3D rigs, animators can modify the rigs, such as making a tail longer, or any other creative changes they need. “You’re basically just putting pre-programmed pieces together almost like an erector set to build your character. There isn’t a lot of trial and error because once you set-up your creature in Modeler and export it to Layout, it just works exactly the way you’d expect it to,” Wheeler said. “With Genoma, an animator can rig a creature without having to understand the underpinnings of the process.” The Flesh of Dragons Most of the CG dragons in Dracano are six to eight feet tall with a massive wingspan and sharp teeth. The dragons have soft flesh covering their bodies and wings that move in relation to the rigid skeletal structure underneath. Soft hanging flesh can even jiggle as the creature moves for greater realism. In LightWave 11.5, Genoma works in conjunction with another new feature, Soft Body Bullet Dynamics to produce this effect. LightWave 11.5 extends LightWave 11’s Bullet dynamics for rigid models to encompass flesh, cloth, rubber, and other soft materials that deform. A dress can blow in the breeze even if the underlying model remains rigid because Genoma and Soft Body Bullet Dynamics understand the distinction between the two materials. “Bullet knows which surfaces to deform based on the weight maps and other parameters you set. These values are not the weight of the creature, they are values you set that define the degree of deformation you want to achieve,” Wheeler said. “It’s like mapping an object by making different areas different colors. One color denotes a rigid structure while another color means that area needs to deform and move in relation to the rigid framework underneath. Genoma works with Bullet’s hard and soft body dynamics to figure out how much each object or surface should bend, collide, flop, wiggle, wave, stretch, or any movement based on how you set it up.” Motion Blur for a Better View The Viewport Preview Renderer (VPR) that was introduced in LightWave 10 has also been extended in LightWave 11.5, making the rendering process much more efficient. Instead of seeing the animation as frame to frame to frame, like a stop motion animation, motion blur gives a better, clearer sense of the animated motion and depth of field without having to go through the full rendering process. Motion blur on the VPR is not a visual effect, it’s a way to preview how the animation will actually look and integrate within the scene. With motion blur inside the VPR, the user can get a feel for the speed of something that’s moving very fast, such as a dragon swooping by, which offers a quick, accurate view of incremental creative enhancements without rendering and saves a lot of time previously devoted to trial and error interspersed with rendering. “LightWave has had motion blur available at the wireframe stage, but now its addition in the VPR makes this valuable tool even more indispensable,” said Wheeler. In the same way that Genoma and Bullet dynamics work together throughout the modeling, layout, and animation process, the VPR is also readily available at every stage of the process. Swarms and Flocks Prior to Dracano, Rogue State produced visual effects scenes for Dragon Wasps, including swarms of dragon wasps flying in the sky. Since hundreds of wasps had to move as an organized group, Wheeler’s visual effects team used the LightWave Flocking feature. In Dracano, many dragon creatures also take to the air and fly around or congregate in caves. But in this instance, Wheeler said they used Instancing to clone one dragon and create a group of 20 to 30 creatures. “Flocking is best to move large numbers of creatures like a thousand wasps to form a deadly swarm. But for a relatively small number of dragons, we used Instancing to create a group. LightWave lets you vary their attributes, like size or colors, and animate them independently of each other,” said Wheeler. “Having a wide array of tools ensures that we have the right one for the unique challenges of every task.” “In our segment of the market, creating visual effects for ultra-low or low-budget features, our visual effects team needs powerful, cost-effective 3D animation tools that get the job done quickly,” said Wheeler. “LightWave 3D helps us meet the production demands of budget-conscious producers without sacrificing the visual impact, credibility, or realism of creatures or visual effects.” For more information: LightWave 3D Home LightWave on YouTube Previous Facebook LinkedIn Copy link Next

Pickleball is the fastest-growing sport for three years in a row. Find out how engineers are designing paddles for maximum performance. Carbon Fiber Foam Core Pickleball Paddle Pickleball is the fastest-growing sport for three years in a row. Find out how engineers are designing paddles for maximum performance. Joe Gillard Sports Jun 16, 2025 Body Helix, a pickleball equipment provider, announced the upcoming launch of their FLiK F1 with TerraCoreXC pickleball paddle which the company says employs their “Gen 4 Expanded Polypropylene (EPP) foam core technology.” The paddles, which are designed for “controlled power and spin,” are slated for release in July, and are USAP-approved. TerraCoreXC Technology TerraCoreXC is the name given to the paddle technology Body Helix says is a patent-pending Gen 4 EPP foam core that “shatters the limitations of traditional polypropylene honeycomb cores.” The core is built using a bonding process. Conventional cores, according to the company, can suffer from rapid breakdown, dead spots, and harsh feedback. For precision, these paddles are designed for a longer dwell time paired with a proprietary high-friction peel ply surface. The paddle also has an area of fiberglass on top of the 4 layers of carbon fiber for “added pop” and for providing power, says the company. Engineered for Excellence The paddle design is a 16.5" x 7.5" elongated shape with a face that features four layers of Toray T700 carbon fiber which the company says gives it its strength-to-weight ratio, and has a central fiberglass area for “added pop.” The handle is made from a solid polyurethane. “This precise layering provides the perfect balance of stiffness for power, flexibility for feel, and surface texture for spin, while the fiberglass layer adds a crucial element of dampening and enhances durability, creating a truly robust and high-performing paddle face,” explained Body Helix founder and head of R&D Fred Robinson in a blog post about the technology. The company says that it utilized player feedback in designing the paddle. “The FLiK F1 with TerraCoreXC is the culmination of over a year of research and player feedback,” said Robinson. “We’ve engineered a paddle that solves real player complaints - a paddle with power that doesn't "break in" while pushing the boundaries of what’s possible in pickleball technology.” Body Helix says players eager to experience TerraCoreXC can try the Sandbox F1XC , a limited-edition Sandbox version, while awaiting the official launch.

Integrated electronic fuse technology helps console designers protect critical power rails while reducing system complexity. Modern Gaming Consoles Require Reliable Power Protection Integrated electronic fuse technology helps console designers protect critical power rails while reducing system complexity. Edited by EE Staff Games Apr 28, 2026 From esports arenas and streaming studios to home gaming systems and immersive XR platforms, modern gaming hardware powers some of the most demanding interactive entertainment experiences ever created. These systems rely on high-performance processors, graphics engines, and high-speed connectivity to deliver real-time gameplay with cinematic realism. Behind these experiences lies a complex power distribution network that must support rapidly changing electrical loads while protecting sensitive electronics. When subsystems ramp up simultaneously—such as during graphics-intensive gameplay—overcurrent conditions can occur. Preventing these electrical faults is critical to maintaining system reliability and uninterrupted gameplay. Figure 1 shows the circuit blocks in an example gaming console. All circuit blocks require protection from overcurrent conditions. Figure 1: An example block diagram of a gaming console. In a recent console design, engineers addressed this challenge by implementing integrated electronic fuse (eFuse) protection within the system’s power management architecture. The Challenge of Dynamic Power Loads Gaming consoles operate under highly variable electrical loads. A sudden graphics-intensive scene or network activity spike can cause several subsystems—including processors, memory, graphics engines, and networking hardware—to increase current consumption simultaneously. External peripherals introduce additional risk. Controllers, charging accessories, and other connected devices can create short circuits or draw excessive current through high-speed interfaces, including USB and ethernet. If these conditions are not quickly detected and controlled, they can lead to: Overheating of system components Damage to printed circuit board (PCB) traces Unstable system behavior or unexpected shutdowns Permanent failure of critical integrated circuits Traditional protection approaches rely on discrete components such as fuses, MOSFET switches, and current-sense circuitry. While effective, these designs increase component count and consume valuable PCB space. As gaming consoles become more compact and complex, designers are increasingly adopting integrated protection solutions that combine multiple safeguards in a single device. Integrated Power Protection In the console design, engineers implemented an electronic fuse (eFuse) device to protect a key 5-V power rail that supplies several internal subsystems and external interfaces. Figure 2 presents a block diagram of an eFuse and a sample application circuit, requiring only three external components. Two capacitors filter noise on the DC line, and the resistor programs the current limit. Figure 2: Example eFuse functional block diagram (left) and typical application (right), providing overcurrent protection, overvoltage protection, and overtemperature protection, as well as other safety features. An eFuse operates as an intelligent load switch that continuously monitors multiple conditions. When abnormal events occur—such as excessive current draw, overvoltage conditions, or overheating—the device quickly disconnects the load to prevent damage. Unlike conventional fuses that permanently open after a fault, an eFuse can electronically shut down and automatically restore operation once the abnormal condition has cleared. This capability is particularly valuable in gaming systems, where temporary disturbances such as peripheral faults or transient electrical events can occur. Monitoring and Fault Isolation At the heart of the protection device is a low-resistance power MOSFET that connects the input supply to the protected circuit. Internal monitoring circuitry measures current, voltage, and temperature in real time. If any single parameter exceeds safe operating limits, control logic rapidly disables the MOSFET, isolating the fault before damage to the system occurs. In the console implementation, the protection device supports load currents up to approximately 5 A on a 5-V supply rail. Engineers can program the current limit using an external resistor, allowing the protection threshold to match the requirements of the specific subsystem. Additional integrated features include: Soft-start control to limit inrush current during power-up Thermal shutdown protection Undervoltage lockout to ensure stable system startup Together, these features allow the device to act as a centralized protection controller for the console’s power path. Efficiency and Thermal Management Thermal management is already a major design consideration in high-performance gaming hardware. Protection components must therefore operate efficiently to avoid adding unnecessary heat. An eFuse protection device features a low on-resistance of roughly 50 milliohms, minimizing power dissipation during normal operation. The device also consumes only about 200 microamps of operating current, allowing it to support power-sensitive subsystems without significantly impacting system efficiency. These characteristics help maintain the thermal balance of the console while still providing robust fault protection. Reducing System Complexity Another advantage of integrated protection devices is the ability to reduce component count. Traditional protection circuits may require multiple discrete components—including fuses, switches, and sensing circuitry—to implement the same functionality. By integrating these functions into a single device, engineers can simplify power-management design while conserving PCB space. In the console application, the eFuse protection device is housed in a compact 2 mm × 2 mm surface-mount package, allowing it to be placed close to sensitive subsystems without increasing board area requirements (see Figure 3). Figure 3: An eFuse LS0505EVD22L housed in a compact DFN2x2_8L package with pinout diagram. This compact footprint is particularly important in gaming consoles, where multilayer PCBs must accommodate processors, memory devices, wireless radios, and high-speed interfaces within a limited space. Preparing for Future Gaming Platforms As gaming technology continues to evolve toward virtual reality, augmented reality, and increasingly powerful graphics hardware, electrical power demands will continue to grow. Ensuring reliable power distribution in these systems will remain a critical engineering priority. Integrated protection technologies such as eFuses provide console designers with a practical way to safeguard complex electronics while maintaining compact designs and efficient operation. By combining fast fault detection, intelligent power control, and small form factors, these solutions help ensure that next-generation gaming platforms remain both powerful and reliable—keeping players immersed in their experiences rather than interrupted by hardware failures. *Images courtesy of Littelfuse.

Inspired by the automation used in Halloween props, this engineer used creativity and technology to pull together a Halloween Box specifically designed to scare trick-or-treaters. How an Engineer Used Spare Automation Components for Spooky Halloween Fun Inspired by the automation used in Halloween props, this engineer used creativity and technology to pull together a Halloween Box specifically designed to scare trick-or-treaters. By Jay Rees, PE, “The Independent Integrator”, Rees Engineering Corp. Cool Stuff Oct 6, 2025 DIY/Home Applications In every haunted house, you’ll find automated props: chairs that rock on their own, slamming doors, rattling chains, drawers opening and closing as if by some supernatural force. These “tricks” enhance the “treat” of getting the life scared out of you. The process behind making a Halloween prop can be quite simple. Here is just one example of how a system integrator put used and spare parts to good use to frighten any trick-or-treater. This article is a perfect example of how creative design engineers are. As soon as Jay got his hands on a wooden crate, he knew it could be something much more than it was. —the EE staff. Trick or Treat I purchased a DURApulse 60HP variable frequency drive (VFD) from AutomationDirect as a replacement for a customer’s damaged VFD. When the shipping container was delivered to my shop, I immediately knew what the wooden crate would become. This crate was just the right size for building a Halloween Box. You may have seen similar Halloween props covered with labels, such as “Danger” or “Wild Animal”. I didn’t know at the time what the final result would be, but I could see “The Box” had potential. I wanted The Box to give the impression that some type of wild creature was inside and was desperate to escape. Because this was a hobby project, keeping down costs was a primary objective. As the owner of a system integration business serving multiple industries, I have accumulated spare components and hardware from retrofitting and upgrading applications. Case in point, the VFD shipping container came courtesy of a wastewater pumping station application. All photos courtesy of Jay Rees. The Box’s controller uses a CLICK programmable logic controller that was removed from a metal alloy chiller system. A C-more EA7 HMI, pulled from a fracking fluid control system, is used to provide displays and audio; I used pneumatic cylinders from previous applications and purchased a couple of new Nitra solenoid valves to assemble “the creature.” Finally, a Rhino power supply was borrowed from stock. Due to my odd assortment of pneumatic cylinders, the next challenge was to figure out what I could do with what I had. A couple of squat cylinders would fit on the bottom of the box, placed between the legs at opposite corners to rock the box and make it look like there was something moving around inside. All photos courtesy of Jay Rees. To give the impression that the ‘thing’ or ‘creature’ inside the box is trying to escape, a cylinder is used to push the lid open. With a padlock hasp connected to the lid, the staple and lock appear to hold the lid closed. What the observer doesn’t know is that the staple is installed in a slot, concealed by the hasp, and a small cylinder is used to hold it down so the lid only moves up and down a little bit. After a few ‘locked’ lid bounces, the cylinder retracts and the lid opens another couple of inches, giving the impression that the creature had broken the lock and is getting ready to escape. To add to the experience, when the lid pops up, a claw (from a Freddy Krueger costume) emerges from the gap in the open lid. All photos courtesy of Jay Rees. If that’s not enough excitement, the C-more HMI, displaying pictures of creepy eyes with simple animation to look like they are moving towards the audience, is mounted near the front of the box behind a small cage providing audio of growling, howling, and snarling animals. While the PLC controls the pneumatic actions, the audio is triggered to play through a set of old PC speakers. To provide a way to save energy when no one is around, and give a more realistic experience, retroreflective photoelectric sensors are used to bring the creature to life when someone approaches The Box. Putting together this project was a lot of fun. The challenge was figuring out what could be put together with stuff that was sitting on shelves and in bins. I still wonder what I would have been doing for fun if that DURApulse VFD ‘Box’ hadn’t arrived at my shop. All components mentioned in this article can be found at AutomationDirect .

When you combine 2,700 LED panels, 42 processors, and 120 distribution units together for one event, you had better do it right. Massive Event Incorporates Over 2700 LED Panels When you combine 2,700 LED panels, 42 processors, and 120 distribution units together for one event, you had better do it right. Edited by EE Staff Stage Events Apr 20, 2026 Microsoft Ignite Keynote Event at the Chase Center in San Francisco delivered a high-profile experience to over 14,600 in-person attendees and over 200,000 live viewers. MeyerPro, a Pacific Northwest event production partner with experience supporting complex live events, is known for dependable execution and a collaborative approach when executing end-to-end services across LED, audio, video, broadcast, and show crew support. The keynote event used 2700 LED panels across multiple ROE Visual platforms including Vanish Solid Touring, Carbon, Topaz, and Graphite, which provided MeyerPro the ability to translate creative intent into flexible, broadcast-ready environments that support complex presentations and workflows at scale. Images courtesy of ROE Visual. For the Microsoft Ignite 2025 event, they were able to deliver a high-profile keynote experience across multiple platforms requiring a visual system capable of supporting live presentation, broadcast workflows, and rapid content transitions across a broad range of stage areas. Microsoft’s expectation was to deliver a stage that felt monumental while remaining highly readable. For the live audience, the displays needed presence, brightness, and a physical quality that felt architectural. For the broadcast audience, the priority shifted to detail, consistent exposure, and color fidelity that remained accurate across camera cuts. This combination was no easy task to complete. Images courtesy of ROE Visual. MeyerPro collaborated across both the design and execution phases, aligning LED and video systems within a broadcast-forward workflow. This approach ensured keynote moments maintained visual consistency regardless of where the content was displayed. The Visual Ecosystem Rather than relying on a single display solution, the design used multiple ROE platforms to support different spatial and storytelling requirements across the venue. Varied panels were used to balance large-scale presence, layout flexibility, and on-camera performance. Each screen served a distinct role within the keynote environment, allowing presentation zones to shift naturally between speaker moments, product demonstrations, and supporting visual content. Images courtesy of ROE Visual. In total, the setup featured more than 20 LED walls spanning a range of sizes, configurations, and curved applications. ROE V4ST and CB3 formed the backbone of the environment, with eight screens built from V4ST (684 panels) and another eight using CB3 (900 panels). Three additional screens used Topaz TP-C2.6 for curved elements (714 panels), while a large Graphite GP2.6 sidewall made up of 420 panels handled the primary wide-format display. All together, the system supported multiple keynote presentation zones while maintaining clarity for both in-room audiences and broadcast viewers—delivering nearly 130 million pixels overall. Processing was built around 42 Brompton 4K Tessera SX-40 LED processors and 120 Brompton Tessera XD data distribution units. The wider show system was centralized around a flypack that included a Ross FR12 and Ultra 60. In addition, the show included a pair of Analog Way RS4s as well as a number of Christie Spyder X80s. The large scale system had many recording options and playback routes via three EVS XT-VIA servers in addition to many PIXERA servers for high-resolution playback. Images courtesy of ROE Visual. The success of Microsoft Ignite continues to highlight an evolution across corporate events. LED is being selected over projection or traditional scenic more frequently when environments require brightness under ambient lighting, rapid content updates, hybrid broadcast workflows, or multi-day flexibility. Production teams can adapt layouts through content and configuration rather than physical rebuilds, maintaining visual impact while reducing disruption.

A Swiss startup — known for its process that makes glass permeable to telecommunication frequencies — requires the right components to create their revolutionary technology. Window Glass on Public Transportation Hinders Cell Service — Until Now A Swiss startup — known for its process that makes glass permeable to telecommunication frequencies — requires the right components to create their revolutionary technology. Edited by EE Staff Cool Stuff Apr 27, 2026 As the world becomes increasingly more reliant on wireless technology in both professional and personal applications, wireless users continue to face certain unique challenges. Making calls or using data indoors can still be a hassle in many locations. This is especially true for those using public transportation like trains, where window glass greatly impacts wireless signals. While wireless signals have become stronger and more efficient in recent years, they still struggle to penetrate building materials, including insulated glass. This makes it difficult, and in some cases impossible, to get service. Everyday clear glass can reduce wireless signals by up to 4 decibels (dB), while coated glass can reduce signals by as many as 30 dB (x1000). This is especially a problem in public transportation vehicles like trains, where passengers may struggle to receive wireless signals at all. It is an issue faced by commuters worldwide, for which Swiss startup nu glass has developed a cutting-edge solution. nu glass’s revolutionary glass cutting pattern allows wireless signals to better penetrate windows. The engraving can be completed on-site without having to remove windows. Unique Glass Cutting Pattern Most glass is insulated with a thin metal layer invisible to the naked eye. nu glass uses a patented laser technology to engrave a pattern on this layer, allowing for wireless frequencies to penetrate the glass. This treatment can increase indoor signal by up to 1000 times. The etching is nearly invisible, and it has no detrimental impact on the glass, which keeps its original protective properties. nu glass uses a portable system to complete the engraving process, allowing them to visit customers on site. The system can engrave glass while it’s in place, preventing the costly and time-consuming process of removing and reinstalling individual panes of glass. The process is fast and efficient and can be applied parallel to standard maintenance, allowing for trains to keep on their schedule and return to service on time with enhanced connectivity. nu glass’s system is currently used exclusively on trains but could potentially be used on glass installed in buildings or other structures. KNF diaphragm pumps play an integral role in nu glass’s cutting process. Multiple N 838 pumps are used in suction plates, which help adhere the system to the window during the engraving process. The pumps allow for the precision process to take place with minimal vibration. The N 838 is an outstanding gas transfer pump option. It offers a maximum flow rate of 34 l/min with an ultimate vacuum down to 100 mbar (abs.). Also available are a variety of motor options, including brushless DC motors for energy efficiency. The N 838 has excellent reliability and operates oil free, preventing media contamination. KNF’s N 838 diaphragm gas pump plays a vital role in nu glass’ engraving system, holding it in place during the precision etching process. While finding the ideal pump for their system was important, nu glass wanted to make sure they were working with a partner that shared their values. A focus on quality and sustainability were key components of those values. It was also important for nu glass, which began its life at the EPFL Lausanne, to work with a local company. This made working with KNF, with multiple facilities in nearby cities and a strong presence in the community, a natural choice. KNF has locations in 24 countries and a commitment to collaborative pump design, which allows each location to serve their communities directly. * Images courtesy of KNF.

Students at California State University, Chico, gained hands-on experience and technical expertise that will empower them to excel in real-world engineering and innovation roles. Students Design Versatile and Scalable Vehicle Students at California State University, Chico, gained hands-on experience and technical expertise that will empower them to excel in real-world engineering and innovation roles. Shannon William Vlaming Cool Stuff May 4, 2026 Design The vehicle platform was all about simplicity and precision. Designed for easy scalability, it used a skid-steer configuration, controlling the left and right wheels independently for unmatched off-road maneuverability. A compact single-board computer handled the drives with analog velocity commands, while a separate computer processed high-level commands, seamlessly controlling the vehicle's actuators over a wireless network. Engineering an initial design was about laying a solid foundation for success by combining creativity, precision, and problem-solving in order to deliver a streamlined, responsive system ready to tackle any terrain with ease. The student engineering team consisted of Laine Wood, Lars Bartels, William Kettle, and Adam Garza. Joshua Mirand was the Capstone Design Program Coordinator who oversaw the project. Images courtesy of California State University, Chico. Handling Multiple Drives As in any engineering endeavor, challenges and obstacles arose throughout each process. The main challenge was expanding control of the drives from discrete signals on the vehicle controller to network-based control over the drives. The existing setup relied on individual signals for each drive, which limited the flexibility and scalability of the system. To achieve a more efficient and dynamic control mechanism, the team aimed to transition to a network-controlled system that handled multiple drives simultaneously with more precision. Every challenge encountered along the way became an opportunity to refine the team’s ideas, strengthen the overall design, and build resilience. By embracing obstacles as part of the journey, engineers set the stage for innovative solutions and lasting impact. ADVANCED Motion Controls played a critical role in the vehicle's design. To ensure the platform could scale easily, Digiflex® Performance DPCANTE-060B080 and DPRALTE-060B080 servo drives were chosen for their versatility. These drives come in a wide range of amperage ratings and form factors, which allowed the team to use the same motion and control system whether they scaled the platform up or down. Images courtesy of California State University, Chico. Working with the Digiflex amplifiers informed AMC was a great experience. The software and documentation were straightforward, which made the integration process smooth. The team was able to get each of the drives controlling the motors within a few hours of unboxing them, which led to an efficient and seamless integration. According to Joshua Miranda, Senior Capstone Design Program CoordinatorCollege of Engineering, Computer Science, and Construction Management, “The performance of these drives met our expectations, expanding our control capabilities and opened up a wide range of possibilities for future developments. We are excited about the potential these new platforms bring and look forward to further advancements.” Images courtesy of California State University, Chico.

Acoustic echosounder simultaneously collects bathymetric, seafloor backscatter, and water column backscatter data to identify seafloor and water column features. Mapping the Seafloor for Underwater Explorations Acoustic echosounder simultaneously collects bathymetric, seafloor backscatter, and water column backscatter data to identify seafloor and water column features. Edited by EE Staff Cool Stuff Sep 9, 2025 Header image caption: High-resolution seafloor mapping revealed unusual pancake-like features of a seamount in the Moonless Mountains chain in the Eastern Pacific. To plan efficient and safe operations, Nautilus (sea exploration ship) often creates its own seafloor maps—particularly when exploring little-known regions of the ocean. To facilitate this operation, the ship incorporates various equipment that provides high-quality seafloor maps at depths to 7,000 meters (23,000 feet). Whether focused on a canyon, seamount, or shipwreck, creating a map allows the crew to identify potential targets, cutting down exploration time and boosting mission efficiency. Before ROVs are deployed, the team must first map the area to understand the characteristics of the region and identify potential benthic habitats, seeps, and other environments and resources worthy of exploration. In addition to informing dive objectives, Nautilus transit routes cover unmapped areas of the ocean and contribute to the Seabed 2030 initiative, an international collaborative project to combine all bathymetric data in order to create a comprehensive map of the ocean floor.

Multibeam Echosounder Mounted on the hull of the vessel is a Kongsberg EM302 multibeam echosounder capable of accurately producing state-of-the-art maps covering large areas of the seafloor. The echosounder maps the seafloor at depths between 50 and 7,000 meters (300 to 23,000 feet) while cruising at ship speeds up to 12 knots (14 mph). The transmit array emits acoustic pulses that ensonify the seafloor with a wide fan-shaped swath of sound, while a second transducer receives the return signal echoes. Each pulse sends many beams of sound in a fan shape toward the seafloor. When these pulses strike the seafloor and return to the transducer/receiver combination mounted on the hull of the ship, the system computes a “sounding” associated with each returning pulse via the time it took to travel down and up through the water column. Because the ship is moving between the transmit and receive functions, a motion sensor connected to the system allows the echosounder to “steer” the sound pulses to correct for the ship’s rolling and swaying motions. This allows the ship to collect an even distribution of data from the seafloor. Received soundings are combined with the ship’s Global Navigation Satellite System (GNSS) information, to produce a grid or “digital elevation model” of ocean bathymetry—essentially a topographic map of the seafloor. Images such as those from Google Earth and other satellites offer very little modern depth observations and only provide general highs and lows of deep-sea topography.

The multibeam echosounder acoustically “sees” different scales and resolutions at different depths. When Nautilus is mapping, the multibeam sonar fan covers a different width (scale) on the seafloor depending on the depth, however the number of measurements across the swath of the fan remains the same. In shallow water, the soundings are closer together delivering many details of the seafloor in a small area (higher resolution data). In deeper water, fewer details are available (lower resolution) but the multibeam fan of soundings covers a much wider area. In addition to the depth, the signal strength that the sonar receives back from the seafloor (“backscatter”) will be different depending on the type of seafloor that reflects the ping. By making corrections to this signal to account for the changes as it went through the seawater from the ship and back, the processing can extract information to indicate variations in the seafloor type. Reflections from rocky seafloor will generally provide a stronger signal than a muddy area. Backscatter measurements are then combined in another grid called a backscatter mosaic, which can be combined with the bathymetry grid to provide a better understanding of the shape and seafloor type. The multibeam echosounder can also detect phenomena in the water column, such as plumes of bubbles emanating from the seafloor that indicate gas seeps. To date, the Nautilus has documented thousands of methane seeps along the Cascadia Margin off the Oregon and Washington coast. Sound waves reflect strongly off gas bubbles emanating from the seafloor. All images courtesy of Ocean Exploration Trust. Exploring Sub-surface Faults Revealing structures below the seabed is just as important as discovering the seascape and habitats above. To complement the multibeam mapping work, the team uses a Knudsen 3260 sub-bottom profiler and echosounder. Mounted inside the hull of Nautilus , the echosounder operates at low frequencies to penetrate and reflect off of the layers of sediment, revealing a cross-section of the seafloor structure. The dual-frequency profiler operates at 3.5Khz or 15Khz (two discrete channels with separate transducers) and is capable of full ocean depth soundings. An acoustic pulse is directed through the water column to the seafloor and then captured by the system as it bounces back from each layer. Scientists use this data to identify subsurface geological structures such as faults, ancient channels, and buried levees. In early 2023, Ocean Exploration Trust installed a Kongsberg Simrad EC150-3C 150 kHz transducer on E/V Nautilus . Mounted within the ship's hull, the EC150-3C is the first of its kind to combine an acoustic Doppler current profiler (ADCP) and an EK80 split-beam fisheries sonar into one instrument. The ADCP, which measures the speed and direction of currents at various depths underneath the ship supports safe remotely-operated vehicle (ROV) operations and provides data for improving oceanographic current models. The integrated split-beam echosounder maps and characterize features found within the water column, such as biology, scattering layers, and potentially bubble plumes. The EC150 will equip E/V Nautilus with the capability to better serve as an operations hub for multi-vehicle operations, increase OET’s capacity to explore and map the water column, and to collaborate with partners from the Ocean Exploration Cooperative Institute to advance combined robotics and new technologies to increase and advance the pace of ocean exploration.

Truss systems used for public events require the right fastener and interface components to withstand shock, vibration, and the high shear values needed for public safety. Coiled Pins Prove More Reliable for Stage Event Truss Systems Truss systems used for public events require the right fastener and interface components to withstand shock, vibration, and the high shear values needed for public safety. Stage Events Aug 13, 2025 Frames for truss systems designed to support stadium lighting, sound equipment, and even bleacher seating systems are often composed of extruded aluminum tubing and solid or tubular couplers. Considerable liability surrounds the use of these systems for public events, and the interface between these components becomes crucial to the integrity of the system. The fastener and its interface with the truss system becomes extremely critical as they are often subjected to shock, vibration, and high shear values when equipment is mounted to the trusses, or while audience members are seated during an event. A top manufacturer of truss systems consulted SPIROL about their needs for an existing design that was comprised of one tubular structural member and one solid male member that slid inside the tubular extrusion and was cross-pinned with two high carbon steel Slotted Pins to hold the coupler to the frame. During installation, the Slotted Pin was difficult to install and would often damage the expensive, yet relatively soft, aluminum frame. Once the hole was deformed, the manufacturer noted instances where the pin would begin to walk out of the hole over time, particularly in permanent installations. This was also noted in mobile systems if subjected to extreme loading. In some instances, the company noticed that the Slotted Pin had stress cracks located 180 degrees from the slot. In extreme weather conditions, the high carbon steel pin was also prone to corrosion. With a lack of options, the manufacturer had investigated implementation of an expensive machined Solid Pin with a secondary retention feature of a Cotter Pin. SPIROL was asked to evaluate the application and ultimately recommend the most robust and cost-effective solution for this incredibly demanding application.

SPIROL’s engineering team determined that 420 stainless steel coiled pins could act as a high-performance alternative to the Slotted Pins being used. Since the Coiled Pin does not need to be aligned in the shear plane like a Slotted Pin, this eliminates the potential of failure due to pin orientation in the hole. Since Coiled Pins remain flexible in the application after installation, they are able to absorb dynamic loading rather than transferring it into the host—which can cause deformation. This reduction in deformation increased the life of the structure, and reduced the potential of the holes opening up to the extent that the pin would eventually fall out. Since a 420 stainless steel Coiled Pin is heat treated, its shear value exceeds that of a machined low carbon steel Solid Pin. Complexity of the assembly was kept to one component rather than two, as proposed with the Solid Pin and Cotter Pin solution; thus saving time during set-up and tear down as well as the task of managing multiple components. By using 420 series stainless steel, the manufacturer would also achieve the necessary corrosion resistance, which would ultimately yield more reliable performance over the life of the structure. An added bonus to the Coiled Pin solution was that no adjustment to the hole size would be required to transition from the Slotted Pin to the Coiled Pin. This benefit extended beyond the manufacturer to their customers that already had truss systems in service throughout the country. Implementation of the Coiled Pin ultimately met all of the manufacturer’s performance and commercial requirements and significantly increased the integrity of the assembly.

The pyrotechnic effects on the Disturbed “Take Back Your Life” tour was precisely controlled for safety as well as a spectacular presentation. Rock Band Uses Musically-Synced Pyrotechnic "Fire Snake" on Tour The pyrotechnic effects on the Disturbed “Take Back Your Life” tour was precisely controlled for safety as well as a spectacular presentation. Terry Persun Stage Events Jan 6, 2026 Image Engineering, based in Curtis Bay, Maryland, designs spectacular pyrotechnic effects for top bands. Music, lighting, lasers, and fire combine to fully immerse the audience in the concert experience. The fully integrated system must synchronize the special effects in real time and stop at the touch of a button for band and audience safety. Image Engineering has been behind some of the most outrageous concert productions of the past few years. The most notable of which were Disturbed’s “Take Back Your Life” rock concert tour of 2023 and Trans-Siberian Orchestra’s 2024 winter tour, "The Lost Christmas Eve." The Image Engineering team often pushes the boundaries of special effects technology by integrating advanced automation and controls into their projects. “The company’s owners are all engineers, and since the beginning, engineering has been central to who we are,” says Ian Bottiglieri, Vice President of Operations, Image Engineering. “That sets us apart from our competitors in the live event space.” Image courtesy of Beckhoff. The Fire Snake concept developed from the need for never-before-seen, jaw-dropping pyrotechnic effects by top-billed band Disturbed. Where most other bands installed video screens, Disturbed decided to have fire as the only visuals for the entire show. Image Engineering worked with the Disturbed production team to ensure that the Fire Snake operated safely and reliably in numerous environments, temperatures, and orientations – within a deadline of less than four months. A trial by fire for engineers The Fire Snake required a lot of R&D work that included how to safely feed the appropriate amount of propane at a pressure of up to 22 psi and maintain a steady pilot light no matter what orientation the Fire Snake is in. The design required replacing traditional burn bars with advanced, responsive burners that could provide more dynamic fire effects. The resulting linear burn system is capable of creating a 3.35 meter (11-foot) wall of fire with proportional control for variable height and shape up to 1.20 to 1.80 meters (4- to 6-foot). In addition, two large burst valves can produce rolling fireballs. The Fire Snake had to be compact and modular to make it easy to transport, assemble, and integrate with existing stage structures from show to show. It was crucial for the automation and safety systems to manage complex fire effects and provide safety assurances to local officials. After various meetings with the Beckhoff entertainment industry team, Image Engineering decided to work with the automation experts to bring the Fire Snake to life. They idea was to leverage advanced PC-based control technology with the integrated safety technology TwinSAFE backed by the EtherCAT industrial Ethernet system. Image courtesy of Beckhoff. Fire Snake comes to life On the Disturbed tour, the Fire Snake had to actively move and change shape according to routines that synced up with the flow of the setlist. When the band first started playing, the Fire Snake rig would slowly come to life and build into more dynamic movement. For that purpose, five segmented Fire Snake units are bolted to a custom truss structure with five winches to change the degree of angle for each unit. A little bit more than a centimeter of clearance between each unit allows free movement yet maintains a continuous, unbroken look to the linear fire effects. Image Engineering’s Touring Accumulator System (TAS) manages the propane from liquid to vapor and feeds it to the effect heads. When adjusting Fire Snake units by 45 or 50 degrees, fuel and fire behave differently and the control system has to maintain the effects and safety. “The Beckhoff system provides the flexibility to not only meet the baseline standards for flame effect systems such as those outlined in the NFPA 160 standard for fire effects but exceed them in many local jurisdictions across the U.S.,” says Nick Hock, Director of R&D and Installation/Integrations, Image Engineering. The Fire Snake features numerous safety measures to ensure trouble-free performances, which are integrated into the control platform via TwinSAFE I/O terminals. One e-stop can halt the entire rig, and the operator can see all safety-relevant status information with a glance at the control console. “It was extremely reassuring to local fire marshals to see a safety system demo and witness the entire Fire Snake shut down to a controlled stop at the push of a button,” Hock says. Installed in the Fire Snake’s shippable case control boxes are CX5140 and CX8190 Embedded PCs with directly attached EtherCAT I/O as primary and backup controllers respectively. EtherCAT and Safety over EtherCAT (FSoE) establish real-time communication and synchronization throughout the entire system including safety devices, and equipment used for lighting and other stage effects. “We have to keep perfect time with the band’s music and lighting,” Hock says. “If we were out of sync even a couple milliseconds, audiences would notice.” The various EtherCAT I/O modules are supported by TwinCAT software to connect flexibly with devices from other networks such as DMX and OSC. For example, Image Engineering uses the EL6851 single channel DMX interface to trigger the Fire Snake’s flame effects. Image courtesy of Beckhoff. Since its completion, the Fire Snake met the requirements for rapid setup and dismantle during multiple tours for Disturbed and Trans-Siberian Orchestra. For example, Image Engineering was responsible for bringing multiple Fire Snakes on the road to 56 Trans-Siberian Orchestra concerts in just 40 days on both the East and West Coasts of the U.S. – at the same time. The Beckhoff system's ability to operate reliably in extremely high ambient temperatures became another critical benefit on the road, especially for concerts in the summertime. “The heat resiliency of the embedded PC hardware is impressive,” Claire Bowman, Associate Director of Engineering, Image Engineering, says. “We've used other embedded systems before that had performance issues on rooftops in Las Vegas when the temperatures reach as high as 49° C (120°F). However, the Beckhoff system always performs without fail.” *Lead image courtesy of Steve Jennings.
