It’s one thing to learn about transmission lines in theory, and quite another to watch a voltage pulse bounce off an open connector. [Alpha Phoenix] bridges the gap between knowledge …read more Continue reading Watch Electricity Slosh: Visualizing Impedance Matching
Birds have long been our inspiration for flight, and researchers at Princeton University have found a new trick in their arsenal: covert feathers. These small feathers on top of birds’ …read more Continue reading Small Feathers, Big Effects: Reducing Stall Speeds With Strips Of Plastic
The small size of action cameras has made them a great solution for getting high-quality experimental footage where other cameras don’t fit. GoPros are [Joe Barnard]’s camera of choice for …read more Continue reading Stripping GoPros To The Bone For Model Rocketry
You might have heard of electrets being used in microphones, but do you know what it is? Electrets produce a semi-permanent static electric field, similar to a magnet produces a …read more Continue reading Electrostatic Puck: Making An Electret
Taildraggers remain a popular configuration for small aircraft, but they come with a significant risk during ground handling: ground loops. If the tail gets too far off course, it can …read more Continue reading Tailwheel Trainer Go-Cart To Avoid Wrecked Planes
Most RC planes follow a simple control scheme: elevators for pitch, rudder for yaw, and ailerons for roll. This one-to-one mapping keeps things straightforward, and fewer actuators means less weight. …read more Continue reading Experimental Drone Flies Like A Bird
Flight time remains the Achilles’ heel of electric multi-rotor drones, with even high-end commercial units struggling to stay airborne for an hour. Enter Modovolo, a startup that’s shattered this limitation …read more Continue reading Modular Multi-Rotor Flies Up To Two Hours
Vehicles that change their shape and form to adapt to their operating environment have long captured the imagination of tech enthusiasts, and building one remains a perennial project dream for …read more Continue reading Transforming Drone Drives and Flies
Old-school technology can spark surprising innovations. By combining the vintage zoetrope concept with digital displays, [Mike Ando] created the Andotrope, a surprisingly simple omnidirectional display. Unlike other 3D displays, the …read more Continue reading A Surprisingly Simple Omnidirectional Display
Battling weeds can be expensive, labor intensive and use large amounts of chemicals. To help make this easier [NathanBuilds] has developed V2 of his open-source drone weed spraying system, complete …read more Continue reading Automated Weed Spraying Drone Needs No Human Intervention
