Modified the remote of a cheap R/C that we had lying around to accept commands through hand movement using an Adruino (Mini Pro) and a Gyroscope/Accelerometer. The boards are mounted to a custom 3D printed platform that has two loops on each side for attaching the mounting straps. The mounting straps are the traditional backpack-style, and have an adjuster on the bottom for tightening. The Arduino uses the position of the gyroscope to drop voltage of the directional and/or accelerate buttons based on the platform's position, using left to go left, right to go right, up/tilt to accelerate, and down/drop to stop. A demo and explanation is posted @ https://www.youtube.com/watch?v=MP1wo0sJzMQ -- Cheers!
