there is or was a company in Santa Barbara CA that manufactures them... I
have seen a video game using this technology... But I have yet to see a
wheel chair equipped with one(that's what their design was for)

I have played with one of these units at a science centre. It has a
couple of electrodes that touch your forehead, and a computer figures out
wh rhythm you are putting out. Depending on that, you could control the
position of a cursor on screen. You could change the position, colour and
shape of a brush in a painting program.

The best I could do was a random set of blotches and squiggles, but I'm
sure with practice peole could do a lot better.

The thing is, there's absolutely minimal energy available here. So for
control it's possible (?) but for energy? No way.

has anyone had a chance to try this out using photodiodes?
lemme get this straight, if using a HC or HCT, then the LDRs or PDs go to
V+ and Grnd > is this correct?
the green LEDs are just indicator lights in that case?
Thanks!
Just tryin to understand it in Laymans terms...
