LDRama

Generates CVs from images on your phone

This module was designed based upon suggestions from Alex Brunori. The idea is to play a video (or Skype or whatever is the newest thing) full screen on your phone and place the phone on the LDR array. The module will generate CVs in response to what is happening in your video.

It is designed to suit a typical 5x2 inch screen, larger screens work fine tho some info around the edges is lost. Ideally the module will sit flat, if on an angle patch-cords into the top row of jacks hold it up very nicely.

There is a pot to set the range, generally tweak this so the LEDs are turning on and off but are not at full brightness all of the time. You can also patch in an external signal, such as a CV from a sequencer, and process this thru the LDRs.

The outputs are taken from each set of 4 LDRs, the top half of the screen, bottom half, left half, right half, left third, centre third, right third and everything.

The concept for this module is not entirely novel, the Journal of Experimental Music suggested gluing LDRs to TV screens back in the 70s.
