psycho and led

2001-11-25 by thom_s4@hotmail.com

Hi all,

Quick question: what max volt range does the Psycho put out? My first
project to get a couple of these boards off my bench is an Oakley
Diode Ladder/CGS Psycho LFO stompbox, and I want to have an led
indicator (or two if it's bipolar).

Another question: Will there be any huge difference if I use a 150k
pot (in a pedal) instead of the 1m speed pot? Should I lower its 18k
neighbor to 1k (or omit it) to help a little bit? I'm going to use
switches w/ bigger speed caps anyway, but a big speed range would
still be nice.

Any opinions on what I should do for the led driver circuit? I think
I have it figured out: psycho volt-->trans base; emitter-->2k2--
>ground; collector-->led (cathode first)-->power. Then I could use
one to +v and one to -v. Would that work? Anyone like to share
something clever/easy?


Thanks yet again,
thom
