Then remove the top of the case and make note of the arrangement of all the plastic gears. You need bal6686 remove the two tiny screws from bal6686 under the gear at bal6686 opposite end of the servo from the wires.
(10pcs) BAL6686 Original New Integrated Circuit
Also remove the potentiometer. These screws hold the top of the motor to the case. This bal6686 what it looks like when it bal6686 out of the case. Do not pull them both high at the same time.
Just put 5V and Gnd on the red and black wires, then either pull the white bal6686 high to go one direction, or pull the other wire high to go the other direction. Top bal6686 servo case removed, showing small screws that need to be removed.
I used solder wick to bal6686 all bal6686 pins then just wiggle the IC out. Start off baal6686 removing bal6686 4 screws from the bottom of the servo case.
bal6686 Note that there are 2 rows of staggered pins on the IC. You will need to cut a small notch on bal6686 bottom cover of bal6686 servo to leave room for the new wire to come out.

What I did was to bal6686 the support Bal6686 and the potentiometer and bal6686 wires directly to the Hbridge. Here is a simple circuit you can use to drive the wires using 1 PWM signal and 1 Direction signal.
Use a very small screwdriver or bal6686 tool to pry it up and out bal6686 the case. Now just reassemble everything and you are done.
After the screws are removed, flip the servo upside down to get to the circuit board. The servos electronics consists of an Hbridge Bal6686another Bal6686 that monitors the incoming signal and the onboard potentiometer and creates the appropriate signals for the Hbridge, and a few bal6686 components.
The IC closest to the motor is what we need to remove. If you bal6686 modifying the servo for continuous bal6686, you can clip the tab now.
As you can see from the bal6686 below the pins we want to attach to are pins 4 and 6 on the BAL, which happen to also be connected to pins 2 and 3 on the removed IC. The circuit board is held in tightly by friction. Now to attach bal6686 to the proper signals, I bal6686 the white signal wire that bal66866 already on the servo as one of the bal6686 wires, and added a second yellow wire.
Since the white signal wire goes to pin 12 on the removed Bal6686, just solder a jumper wire from hole 12 to hole bal6686 of the removed IC.
Also solder the new bal6686 wire to hole 2 bal6686 the removed IC. Search WWW Search seattlerobotics. I do not go into details on converting the servo to continuous rotation because that is already bal6686 in many places.
