Introducing the WRONGAMIN noise maker synth

Disigned and built by Leafcutter John. Full schematic at http://www.leafcutterjohn.com

The Wrongamin is an excellent, easy to build sound maker that can create a range of sounds. From crackles not unlike the sound of a dusty old record to a deep hungry animal growl heard through several out of control AM radios.

It uses three LDRs (Light dependent resistors) to change the pitch of Three very high frequency oscillators. What is interesting about this machine is that in normal operation we don't hear the oscillators directly as they are tuned far above the highest sound a human can hear. What makes this instrument audible are the interactions between the three oscillators which project downward into the realm of our perception. Some Theramins operate on this same principle and this is where the Wrongamin gets its name.

"A Theramin can sound very wrong in the wrong hands, a Wrongamin sounds wrong in everyones hands"

If you make it please leave a comment or video comment - I want to see your creations!

John.

do it Dan, you can try a range of capacitors for c1,c2, & c3 bigger caps will give a lower pitch.

Let me know how you get on!

1:30 It didn't like THAT!
