I especially like the photodiode that Fairchild made just
for us, QSB34CGR. Y'all can buy them now too :)

That has an IR filter?

No, they left it off for us :)


Is that why there's an extra character in the part number? 

Indeed. "C" for "Clear" would be my guess.

And thats exactly what they look like. Quite pretty actually :)

To be honest, I am absolutely astounded that they made that part. So far, we have only made 20-30 pre-production prototypes. Admittedly they each have 121 photodiodes. But the projected sales volume is tens of thousands per annum, so thats millions of photodiodes. Hey, this is almost as neat as building LED video screens :)

But thats not so cool.

Aside from the fact I get paid, its heart-warming to design something thats truly helpful. These guys went from 2 to 20 wpm with LOMAK. Not that any of that is my doing, I just designed the circuitry, the really clever stuff is how the user interface works. Its the brainchild of a guy who worked as a sparky at a facility for disabled people, and was disgusted at the primitive human-computer interfaces available (mostly a stick held in the mouth). He then went to tech and studied electronics, so as to built a proof-of-concept prototype. A very clever man.
