Since now you're going to either
register your drone or have to be flying your indoors anyway in the USA, you might as well celebrate the one freedom you still have the freedom to re-flash the firmware with open source! 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 acrobatic mode, or simply to tweak the throttle-to-gyro mapping for the quad. The firmware author silverxxx from RCGroups.com even got the
code up on GitHub if you're interested in taking a peek. Next step, Skynet!
