My organ is finished but I have no monkey! I searched online for the perfect mechanical monkey and came across a toy that was made in the 50's and 60's. The toy was rusted and broken. I replaced a broken motor and sewed a new pair of pants. The monkey interacts with the organ because of an Arduino microcontroller. I also used the guts of an old voice changer toy. The mic from the toy is now used as a sensor to detect a certain level of sound, which
activates the monkey to turn on. Everything is nicely fitted into a small canvas backpack I made. I am excited to test this guy out!!
