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
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!
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!
