- Soldering iron
- Wire cutters
- Precision screwdrivers
- 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.
