The holidays always remind us of our favorite toys from when we were kids. Johnny Astro, an Erector set, and — of course — a Spirograph. [CraftDiaries] has an Arduino machine that isn’t quite a Spirograph, but it sure reminds us of one. The Arduino drives two stepper motors that connect to a pen that can […]
Well, we’ve seen a few experiments with the Gameboy camera over the years, but this one is pretty wild. YouTuber, car nut and 3D printing fanatic Conorsev has developed and printed an adapter that lets him mount Canon EF mount lenses to his Nintendo Gameboy Camera and it produces images far greater than the Gameboy ever deserved. While it might be a
Multiplexing is a very old technology in which control signals are intermixed for the sake of being able to control more devices than there are control signals. For [mihai.cuciuc], the problems started when he multiplexed some very efficient LEDs. The problem? In two banks of six LEDs each, both LEDs connected to a single Arduino pin would light,
Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just that, relying on some staple maker components to do so. The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B

Assistive technologies have a pretty big presence here on Hackaday, and this hack is nothing short of interesting. [kerchoo_22] is working on a hands-free video game controller as a final project for her engineering class and we think it’s worth sharing. The basic premise of the circuit is pretty simple. She DIY’d a few contact switches using conductive plates
Arducon is an Arduino based ARDF transmitter controller specifically designed for for conducting amateur radio direction finding and is now available via Kickstarter. The unique piece of kit has been designed for active radio enthusiasts involved in the outdoor sport of Amateur Radio Direction Finding (ARDF). Backer early bird pledges are now available for the novel project

Many infamous Kickstarter projects have ultimately flopped or failed, leaving backers frustrated and angry. Often pitched with a splashy convincing video that happens to have critical components conveniently offscreen. [Allen Pan] was reminiscing about one such project, the air umbrella, and decide to redeem the project by making his own. The basic idea of the air
Electronics hobbyists, engineers and developers looking for an automatic way to create KiCAD schematics may be interested in your project created by Nick Bild, capable of analyzing your physical breadboard and automatically generating a KiCAD schematic. Although it is worth mentioning that the script is have some limitations such as many ICs either don’t have internal continuity
Create KiCAD schematics automatically with Schematic-o-matic Continue Reading
Restoring vintage computers is the favorite task of many hardware hackers. Retrocomputing probably makes you think of home computer brands like Commodore, Amiga, or Apple but [Erik Baigar] is deeply into collecting early military computers from the UK-based Elliott company. Earlier this year he made a detailed video that shows how he successfully brought an Elliott

When [jns] and their colleague came across an industrial or possibly military grade keyboard/trackball combo on eBay, their minds did the same backflips that yours or mine might. Enthralled by the specialty key caps, the custom layout, and companion trackball adorned with its own keys rather than buttons [jns] and his workmate they did the only thing that
