I've never used this list before so here's hoping...
My lab is looking to contract someone to build us several photodiode
transducer boxes. This is a pretty simple electronics project, but I
don't have the time to figure out how best to do it and do it myself.
Basically we need a plastic box (fabricated somehow) with a few dials
on it that takes batteries or optional wall plug, a line out, and a
cable to a screen-mountable photodiode. The knobs should just be for
gain, and they need to be discretely labeled in some way, i.e. a
continuous knob is undesirable.
We use this attach a photodiode to a laptop screen and convert the
screen light into an analog signal that we can feed into an EEG system
to synchronize it to the brain signal. As seems to be the case often
in physiology, the mainstream electronics world has moved on to other
technologies and we're stuck with this stuff due to our unique
situational constraints. It's now extremely hard to find these for
purchase, and ours are all dying slowly.
If you're interested in the job, or can refer me to someone, please
email. I can discuss spec and compensation in detail.
