A button that stopped working has probably led to more than a few smashed remotes over the years. Fortunately [pescado99] has shared a beautifully simple cure for dead or dying …read more Continue reading Fix That Old Remote With Graphite
Gyroscopes are perfect to damper short impulses of external forces but will eventually succumb if a constant force, like gravity, is applied. Once the axis of rotation of the mass …read more Continue reading Combining Gyro Stabilisation With Weight Shift Balancing
Although we think of air-to-air radar as a relatively modern invention, it first made its appearance in WWII. Some late war fighters featured the AN/APS-13 Tail Warning Radar to alert …read more Continue reading Bogey Six O’clock!: The AN/APS-13 Tail Warning Radar
Applying solder paste to a new custom PCB is always a little nerve-racking. One slip of the hand, and you have a smeared mess to clean up. To make this …read more Continue reading Portable Solder Paste Station Prevents Smears With Suction
Dealing with all the wiring can quickly become a challenge on robots, especially the walking variety which have actuators everywhere. [Eric Yufeng Wu] sidestepped the wiring issue by creating Q8bot, …read more Continue reading Little Quadruped Has PCB Spine And No Wiring
Steam turbines have helped drive a large chunk of our technological development over the last century or so, and they’ll always make for interesting DIY. [Hyperspace Pirate] built a small …read more Continue reading Small Steam Generator Creates Educational Experience
Venus hasn’t received nearly the same attention from space programs as Mars, largely due to its exceedingly hostile environment. Most electronics wouldn’t survive the 462 °C heat, never mind the …read more Continue reading Clockwork Rover For Venus
For serious high-voltage plasma, you need a serious transformer. [Jay Bowles] from Plasma Channel is taking his projects to the next level, so he built a beefy 6000:1 flyback transformer. …read more Continue reading Pushing the Plasma Limits With a Custom Flyback Transformer
[bitluni] seems rather fond of soldering lots of LEDs, and fortunately for us the result is always interesting eye candy. The latest iteration of this venture features 8 mm WS2812D-F8 …read more Continue reading Modular Magnetic LED Matrix
Lenz’s Law is one of those physics tricks that look like magic if you don’t understand what’s happening. [Seth Robinson] was inspired by the way eddy currents cause a cylindrical …read more Continue reading Levitating Magnet In A Spherical Copper Cage
