Over the past few years a number of teams have been putting a lot of effort into taking beloved Nintendo 64 games, decompiling them, and lovingly crafting them into highly portable C code. This allows for these games to not only run natively on PCs, but also for improvements to be made to the rendering engine and other components. Yet this artisan...

[Peter Holderith] has been on a mission to unlock the full potential of a DIY quad-motor electric go-kart as a platform. This isn’t his first rodeo, either. His earlier vehicle designs were great educational fun, but were limited to about a kilowatt of power. His current platform is in theory capable of about twenty. The last big change he made was...

To that end, [kuokuo] built a machine of their own to do that very task. Even better, they’ve made it open source so other hobbyists can benefit from their work.

He decided to figure out if he could use it for some kind of communication, and whipped up a circuit to test it out. To do the job, he designed a modulator circuit that could drive...
