How to Make a Dc Motor Gearbox Became Servo Motor

using a cheap servo is the best choice to make small projects, but the bad quality of gear, easily damaged. Do not quickly make a decision to dispose of the damaged servo, you should see this tutorial first. :)

If you have damaged servo on the gear mechanism, and you still need it, but don't want to spend a lot of money . This is what you need :

1. Plastic dc motor gearbox good tors, price only $1.87 http://store.extremeelectronics.co.in/6V-DC-Gear-M...
2. super glue
3. electro tool

• remove the electronic modules (motor driver) from the case broken servo.
• on Potentiometers , cut the handle grip of potentiometer .(look to the picture no.2)

• unplug the plastic adafter shaft on the back side of the gearbox
• make a hole right in the middle of the handle grip of potentiometer is in pieces last. make a hole the same size as the gearbox shafts
• plug the potentiometer to the shaft gearbox, give a little super glue, make sure the glue holding a potentiometer to the gearbox shaft.
• use a plastic plate size 1cm x 5cm (im using a PVC plastic pipe), with a hot fire flame to forming the plastik to a shape like a pic no.6
• plug the plastik to the gearbox, holding the potentiometer on gearbox, use a little super glue. make sure the plastic stick to strong and withstand potentiometer in place.

• solder the wires to the motor output of motor driver circuit.
• output (+) on circuit to (+) motor input and output (-) circuit to (-)motor input.
• plug the circuit to the gearbox body use tie band or give a little glue gun.

• Test your new servo using RX/TX remote control or any microcontroller. if not work look back to a line wiring or check a circuit motor driver.
• Now you have unique servo with good tors and more powerfull.
