I was recently inspired by a Kickstart project which used Bananas as sensors to control a video game on a PC.  I've done some video game controls using the Propeller in the past, but I thought this would make an interesting synthesizer project.

Introducing: Bananaphone: A Touch Capacitance Synth


Step 1:

Parts List:
  • Your favorite Propeller board.  (I used a Quickstart board w/Terminal Module)
  • A couple packs of alligator jumper wires. (Radio Shack)
  • Nine Bananas (8 notes & 1 to snack on)
  • A 220ohm resistor (Radio Shack)
  • An amplified speaker w/connector
  • The spin source archive

It would be ironic to play "Yes, We Have No Bananas!" with Bananaphone. You made The Humongous laugh. He salutes you.
Did you try to play some Velvet Underground tunes with it ? I think that John Cage will be pleased.
This, sir, is very Gangster ;)
I'm picturing a "banana contest" in the future.
awesome !!!
I'll keep this instructable printed and locked into a folder just to allow my daughter tell her friends in school that her father can make bananas sing!
When will I start seeing these in music stores near me? <br>
Well that's it. This is the best instructable ever.
I'll have to try this with an Arduino.
that is amazing! how useful are bananas?! the skins are also great for removing insolubles like metals from water - great for the wastes management industry.
