Why haven't we been arrested?

Autopilots are export controlled by the International Traffic in Arms Regulations (ITAR), which is why it's very difficult for US manufacturers to sell abroad without incredibly complicated guarantees about security procedures put in place by the buyer. That doesn't just apply to autopilot hardware; it also covers autopilot software, groundstation code and other technology in digital form such as schematics. And "export" doesn't just mean physically sending boxes abroad, it also covers "export… Continue

DIY heli---don't even ask why

If you positively, absolutely have to DIY everything, here's a how-to on building your own electric heli with a CD-ROM motor. It's the first Angelfire site I've seen for about a decade, so be prepared for a jarring '90s flashback on website design ;-) Still, the… Continue

Stanford's autonomous helicopters teach themselves how to fly

Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by watching other helicopters perform the same maneuvers. The result is an autonomous helicopter than can perform a complete airshow of complex tricks on its… Continue

Easy datalogging with Arduino

Doing traditional datalogging with Arduino is a pain. It only has 1k of RAM, and half of that is used by the program, so you can't store any significant data in its own memory. Meanwhile, writing to a SD card, as the Adafruit GPS logger does, takes pretty much all of its computational power, leaving little left for useful work. This is not unique to Arduino--it's true for any 8-bit embedded processor. You can add… Continue
