[Open source firmware turn toy quadcopter into acrobatic drone]

Very cool hack in the classic DIY spirit from Hackaday:

Since you’re going to register your drone or have to be flying your indoors anyway in the USA as well celebrate the one freedom you still have — the freedom to re-flash the firmware!

The Eachine H8 is a typical-looking mini-quadcopter of the kind that sell for under $20. Inside, the whole show is powered by an ARM Cortex-M3 processor, with the programming pins easily visible. Who could resist? Garagedrone takes you through a step-by-step guide to re-flashing the device with a custom firmware to enable acrobatics, or simply to tweak the throttle-to-engine-speed mapping for the quad.The firmware comes from silverxxxh even got the code up on GitHub if you’re interested in taking a peek. It looks like it’d be fun to start playing around with the control algorithms. Next step, Skynet!
