As mentioned in previous log I have built a spinoff version of the project. Here are the details:

Only 3 components were used to built the unit (besides the footswitch itself as well as the USB cable).

• A Digispark Clone
• A P10 jack
• A small box

The plastic flanges were trimmed and a hole was made for the P10 jack

Then another hole was made on the opposite side of the box for the USB connector. The board was attached to the bottom cover of the box using two threaded screws.

The plastic spacers were trimmed to match the height of the board with the window for the USB connector.

The Jack was then wired to the board. Since the switch is Normally Closed a bridge wire was used to keep the wires short circuited when the plug is not inserted.

The firmware was then uploaded and the pedal was tested using a web application from Microsoft from a page about keyboard ghosting (very interesting by the way).
