==Tools needed==
* Soldering iron
* Solder and flux
* Wire cutter to cut off component pins

==Suggested Work order==

* See image above for component values.
* Start with the crystal.
* After that it is probably a good idea to do all 0603 components.
* Use 10kΩ resistors if your keyboard has blue LEDs, 510Ω if they are Red. You would do best to check what value your original controller has for the LEDs.
* Solder the controller and decoders.
* Solder the 10µF capacitor.
* Add the pin headers and the reed switch.
