Potentiometer slot. Servo modification question

(1/2) > >>

garriwilson:
In my servos, the slot for the pot in the main gear isn't separate from the gear. I don't have a dremel or a drill and my parents are going to give me any more money to buy one. :'( Any other way I could do that step to make the slot round?

KambeiX:
one solution would be removing the pot and replacing it with resistors if you have a soldering iron.

Hmm... you could also cut the pot shaft , center the pot and melt the rest so it stays firm. (I've done that with hs-311)

garriwilson:
Sorry I'm a noob could you like give detailed instructions if it's not a problem for you?

KambeiX:
Hmm I don´t have a detailed tutorial but there are many on the net. Just look for how to modify a servo for continuous rotation.

You don't need a dremel or drill, just some screwdrivers and an xacto knife , since you can also get the pot outside the servo case without having to melt anything



Here is a picture of a modified servo with the pot outside the case.

The idea is to replace it with something of a value close to the original that's easier to regulate (many turns, not just 180° like the original).

Just be careful and don't break anything

garriwilson:
So I'm just supposed to take the pot out or replace it with something?
