12!
I never made a video for this and have now taken out the necessary diode in prep for the next chapter project, but the last thing I did for this contract Winter quarter was to find the clock circuit in an electronic Wiggles guitar toy. When you use your human connectors (fingers) as variable resistors on the "clock" resistor circuit (the one that times the frequency of sound let out of the toy), you can make the Wiggle's get weirder than ever before!
Here is Nic Collins tutorial it is pretty freaky: http://www.nicolascollins.com/hackingtutorial10.htm
Stay tuned since I'm continuing this contract into Spring quarter (which starts tomorrow)! woop
