These are my build notes for the nonlinear circuits LDRama module.
tHIS eurorack 28HP light sensor module was designed upon suggestions from Alex Brunori.
The idea is to play a video (or skype or whatever is the newest thing) fullscreen 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.
I've got a Arduino controlled LED project in the works, and I'd like to see if I can do something interesting with the two.
I think this is a pretty neat idea.
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
You can also patch in an external signal, such as a CV from a sequencer, and process this thru the LDRs.
The BOM suggests using GL12528 LDRs x 48
get the opamps on first.
TL072 x 15
resistors next.
lots of 1k and 100k
These 8 resistors marked 100k should all be 1k
The RL and 1k should be swapped
2k2 resistors for RL
I'm using a 10R resistor for reverse
voltage protection
The LDRs are larger than the usual
You need 48 x GL12528
on order from ebay
to be continued.....
