Nice little guide to building an IR transceiver - uses the USB port for stable 5V, but includes a link in the comments to a decent circuit diagram that uses a voltage regulator and therefore doesn't need the USB port for power.
every game starts out as the handmade creation of the inventor, which eventually becomes a standardized and mass produced product; but sometimes the commercial versions of games are not available, too expensive, or just not nice enough
basically the Flash Nap project with a few extra features and some work. It's also a minimal version of "Light/Sound" hypnosis machines that cost hundreds of dollars, but if you have parts, this one will cost just a couple of bucks. NO PROGRAMMING REQUIRE
four-channel GPS receiver using a repurposed FPGA board from a previous frequency synthesizer project. Connected to a PC running a console app, the receiver is capable of tracking four satellites simultaneously, which is good enough to capture lat, long, and altitude.
video takes you through the process from start to finish, including all of the components you'll need to make your own: the mixing bowls, the fan motor, the propane torch, and of course, the sugar.
