Tools

• Soldering iron
• Multimeter
• Wire cutters
• Precision screwdrivers

Materials

• A servo! We'll be using "Micro" servos here but any size will do
• 2.2k 0805 resistors (thick or thin film is fine)

This hack will work with just about any servo... but the ones that have the potentiometer contacts in a row will be the easiest (by far) to mod.

Here is an example of a standard Micro 9g servo driver with the potentiometer leads removed. We will be placing resistors between those three contacts on the bottom.
