Christmas project: Sustain pedal

For this Christmas holidays I thought in a project to spend my free time. A inconvenient of my projects is that once they are finished they become junk useless which I don't want to throw away but neither keep them. Therefore, this time, I tried to think in something useful, and more or less is this:

Sustain pedal

What is that fuc*?

A sustain pedal is an element which connected to a keyboard (electronic piano) prolong the duration of the sound while you put your foot on it.


This pedal has a 6.3 mm jack output and a switch to enable sustain permanently without keep the foot in it.

 The thing is that I don't pay attention to pedal signs in music sheets...
By the way... It works.
