Here I share my modifications done to the Mini Quadruped from TheCASE.At the moment the arduino board and the servos are powered by the same power source from the adafruid board. Not sure if that is the best way. Let me know about your ideas. I am still working on the program code. Here a first result: http://www.youtube.com/watch?v=9_4LRIga8AgI am using this hardware: Battery Backbone Assembly:Use the printed parts and 2x M3 bolts and nuts to assemble the battery backbone with the mounting plate. To put a breadboard on the top, use a driller to make two 3.2 mm holes into it. Then assemble it with 2x M3 bolts and nuts. After inserting the battery box you can secure it with the two clamps at the bottom.
