Over on his secondary YouTube channel, [Jeff Geerling] recently demoed the new Mitxela Precision Clock Mk IV. This clock uses GPS to get the current time, but also your location so it can figure out what time zone you’re in and which daylight savings time might apply. On the back a blinking diode announces the […]
You can get just about any gear reduction you want using conventional gears. But when you need to get a certain reduction in a very small space with minimal to no backlash, you might find a wave drive very useful. [Mishin Machine] shows us how to build one with (mostly) 3D printed components. The video […]
Electric cars are everywhere these days, but what about boats? Looking to go green on the water, [NASAT] put together this impressively nimble boat propelled by a pair of brushless motors. The boat itself has a completely custom-built hull, using plywood as a mold for the ultimate fiberglass body. It’s a catamaran-like shape that seems […]
Perhaps you have a tilt towards glowing cyberpunk peripherals. Perhaps you’ve been hunting for a keyboard that you can position perfectly to suit both your left and right hands. In that case, you might just like this nifty design from [Modern Hobbyist]. The first thing you’ll note is the split design, which allows each half […]
Software Defined Radio (SDR) is the big thing these days, and why not? A single computer can get rid of a room full of boat anchors, and give you better signal discrimination than all but the best kit. Any SDR project needs an RF receiver, and in this project [mircemk] used a single 6J1 vaccum […]
When a man wearing an Atari T-shirt tells you he’s buying Commodore it sounds like the plot for an improbable 1980s movie in which Nolan Bushnell and Jack Tramiel do battle before a neon synthwave sunset to a pulsating chiptune soundtrack. But here on the screen there’s that guy doing just that, It’s [Retro Recipes], […]
[devicemodder] wrote in to let us know they managed to install Linux Mint on their FRP-locked Panasonic Toughpad FZ-A2. Android devices such as the FZ-A2 can be locked with Factory Reset Protection (FRP). The FRP limits what you can do with a device, tying it to a user account. On the surface that’s a good […]
As much as people love USB-C, there’s one massive flaw that becomes very obvious the moment you look at the ports on any computer. This being that there’s no (standardized) way to tell what any of those ports do. Some may do display out (Alt-Mode), some may allow for charging, but it remains mostly a […]
[Moby Pixel] wanted to build a fun MIDI controller. In the end, he didn’t build it just once, but twice—with the aim of finding out which microcontroller was most fit for this musical purpose. Pitted against each other? The ESP32 and Raspberry Pi Pico. The MIDI controller itself is quite fetching. It’s built with a […]
When you watch a movie and see those perfect focus switches or zooms, the chances are you’re not seeing the result of the cameraman or focus operator manually moving the lens controls. Instead, they will have been planned and programmed in advance and executed by a motor. If you take a close look at many […]
