Title: Modify servo... help asap before my dad solders stuff
Post by: offy on March 03, 2009, 05:35:20 PM: I have broken the meter thing inside of the servo but I had an old one and my dad is about to solder the wires to it. Is there a way I can combine the 3 wires together to simulate 0 degrees? PLEASE HELP!

Post by: offy on March 03, 2009, 06:33:54 PM: I have a servo that was for 180 use only. I modified most of it until I broke the meter. Is there a way I can connect the wires together to make it work right?

Post by: offy on March 03, 2009, 08:02:05 PM: I tried to glue it, than the top of it got glued to the table, I pulled it the top came off and so did the wires. So now I have 3 wires, and I got a potentiometer from one of my old servos there were broken.

Post by: Trumpkin on March 03, 2009, 08:41:26 PM: You could just solder in some resistors instead of the potentiometer. See this tutorial http://www.societyofrobots.com/member_tutorials/node/82 (http://www.societyofrobots.com/member_tutorials/node/82)

Post by: offy on March 03, 2009, 08:43:36 PM: I don't really want to mess that much around with a servo. I don't have a small enough solder and don't have enough to buy one right now. Please, any other ideas?

Post by: Razor Concepts on March 03, 2009, 08:47:06 PM: Well if you cant solder resistors in there, there isn't really any other way... just let your dad solder in the potentiometer.
