This is a quick little project i did one night after work!
I was itching to solder something, so here it is! My cure for boredom!
You will need the following:
1 x Servo
1 x Screwdriver
1 x Soldering iron
1 x Wire snippers
1 x X-acto knife
1 x Connectors of your choice
Step 1: Take It Apart!
Take your servo apart!
Remove the four screws at the bottom. Get rid of the servo wires (snip or de-solder, your choice)
Do the same with the 3 wires connecting to the motor.
Step 2: Gut It
Now take it apart completely, all the gears should pop out pretty easily, remove the motor and the small circuit board connected to the potentiometer.
If you want to keep the small circuit board & POT, go for it, but otherwise, throw 'em out, we won't be putting them back in the motor!
The motor should be attached by two small screws. DONT LOSE THEM!
Step 3: Modify The Gears
A servo is only made to rotate a certain degree range, we have to change that.
Put the big gear that attaches to the servo horn in a clamp or vice.
Take your x-acto knife and remove the stop tab.
In this particular servo two of the teeth of the gear are filled in, simply cut the teeth out with the x-acto knife!
Step 4: Reconstruct!
You're almost done!
Now solder your own wires or connectors to the small motor & screw it back in place!
Your ready to put it all back together, simply put your modified gears back as they were.
Put the four screws back in the case & run your wires out where the old ones were!
Step 5: You're Done!
You've done it!
Now you can use this anywhere you need!, without a servo tester or tx/rx system! In my opinion it has a great ratio between power and speed (of course this may vary between servo models) but overall this thing rocks!
Hope you enjoyed my Instructable!
