Half-Life Hopper Mine 3D Printing Modeling & Electronics Prototyping based on ATTiny83, Tilt Switch, RGB diode (status change), PCB, and C code. I still have to implement the motor to move the legs, the battery and the switch. You can find the non robotics compact version here : tinyurl.com/yw2vnwzm
