The team at North Street Labs really went all out with this Tic-Tack-Toe stomp box. At its most basic it’s a blinky version of the simple two-player game. But there’s always some added appeal when you make large manifestations of normally small items; the 10x Arduino is a good example of this. The project is NSL’s […]

After seeing a Game Boy emulator for the first time, [Thijs] was amazed. A small box with just a handful of electronics that turns a Game Boy cartridge into a file able to be run on an emulator is simply magical. [Thijs] has learned a lot about GB and GBC cartridges in the mean time, […]

LED retrofit for vintage edge-lit numeric display modules

This single digit display is an old edge-lit module that [Ty_Eeberfest] has been working with. The modules were built for General Radio Company and have a really huge PCB to control just one digit. [Ty's] modules didn’t come with that driver board, so he was left with the task of controlling an incandescent bulb for […]

Here’s an Android powered pen plotter that does it all. It was built by [Ytai Ben-Tsvi] to take with him to Maker Faire. He’s the creator of IOIO, a hardware interface module designed to communicate with an Android device via USB (host or OTG are both supported). The physical hardware is simple enough. He draws […]

For those of you who might have forgotten, let’s go over the rules of Centurion. The object of the game is for every minute, for 100 minutes, drink a shot of beer. It doesn’t sound like a lot, but after completing the challenge you’ll have had 3 liters of beer (or about eight and a […]

Homebrew GPS gets ±1 meter resolution with a Raspberry Pi

We’ve been following the work of [Andrew Holme] and his homebrew GPS receiver for a while now. A few years ago, [Andrew] built a four-channel GPS receiver from scratch, but apparently that wasn’t enough for him. He expanded his build last year to track up to eight satellites, and this month added a Raspberry Pi for […]

Do you ever wonder why geese always fly together in a V-shape? We’re not asking about the fact that it makes the work load much less for all but the lead goose. We mean how is it that all geese know to form up like this? It’s is the act of flocking, and it’s long […]
