The idea of this contest just striked me: Use a given lenght of "arm" and a maximum of e.g. 3 motors ( servos, stepper, fans, watercoolingpump, whatever ) and compete against a scale or another competitor. Show us a ( uncut ) Video of your results.
Please add your suggestions of further rules, if you like.
Should we start with a beginners class with the cheap and welknown 28BYJ48 Motor with ULN2003 Controller?
May the torque be with you :D
