After purchasing an older Hammon M2 organ and being dissatisfied with the sounds from the pedals, Ron Czarnik refurbished and remounted them into the housing of a child's piano to create a fantastic MIDI-compatible instrument with the help of an Arduino.
Although the original pedal circuit design was somewhat daunting, with some research Ron has converted them to simple switches so they can be read by the Arduino's digital inputs - at which point the MIDI translation and output can easily be created. Finally the new enclosure is a work of art, as shown in the following video:
A great use of some older parts which have been converted into something new - for complete details visit the project Instructable page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
