infared foot pedals? and how to achieve this.

I have built a some of the B.Y.O.C. pedal kits and downloaded some schematics and built 'em from that point.

Just recenctly a friend of mine bought this boutique noisemaker box.
A primitve squarewave synth by my ears. the thing that really got me into it was this little clear bulb/diode with what looked like a little microchip embedded in it. If you ran your finger over the this bit it would change the sound. I'm assuming it is some kind of infared voltage control.

This is a movie of the little guy in action...

Does somebody on here know what the hell i am talking about?

Links, pictures, schematics what i should refer this as so i can buy some?

Thank you EA.

I had an Ibanez AD-9 modded like fuck by the guy from Death By Audio. It had an oscillation switch and a switch that turned on the 'theremin eye' controller, which adjusted the delay time. It was very difficult to use subtley, though I believe it was intended for use with trippy stage lights, which I don't fuck around with.

It was alright. Apparently the guy who I bought it from fucked with the trimpots something crazy, which I didn't find out about until the dude I sold it to bitched about it. He sent it off to the guy and had it adjusted for free. I wish I would've gotten a chance to hear it after he fixed it.

It's been suggested that somehow we take a Golden Tee track ball controller and somehow hook it up to some Moog/LFO mod thing and use it as a foot pedal. I.e., you kick it in different directions, and you'd get a really fast to slow woo-woo-woo-woosh sound, etc.

Would anyone know of an effect that could be modded to accept said controller as an input device?

I've heard of people connecting theremins to the cv inputs of moog ring mods with good results. I guess if you wanted to do the Jimmy-Paige-wave-your-arm-like-around-like-a-magician thing it would be cool.

The expression pedal needs to send voltage (about 5v) to the unit. The trackball would have to be able to be hooked up to a voltage source (a nine volt battery would work) and then control the voltage sent out to the pedal. This is only the case with voltage controlled units. You would have to figure out what the trackball is putting out (come to think of it, its probably digital, so good luck with that) and how the expression pedal section in your pedal works. I would ask over at www.diystompboxes.com.

hook it up to an oscilloscope and find out what it's outputting or find a datasheet with the part number. There are tricks you can do to easily convert it to analog if it's digital output, like either a weighted ladder (parallel digital output, not likely) or an integrator circuit with buffered output (for serial, this will likely need to be calibrated, might be hard to implement). Then you can get a voltage output for this and then you can do just about anything.
