Hi Lee, Couldn't quite make out your picture...(kind of dark)... a couple of things to look for... it should be a 3 wire connector (some really old servos...
Servo Terminology: Indirect Drive - This refers to the potentiometer inside the servo. The final output shaft (the part that the horn/arm attaches) has to be...
Hi.. I've been pulling together a design for a robot that has a disparate set of components. Unfortunately, the different subsystems have differing power...
Hi Jay You may want to look into rolling your own DC-DC using either the National simple switcher parts or the Linear tech parts. Both suppliers have plenty...
