 These are TRW photo interrupters, and although you have to buy $40 worth at
a pop, that gets you 265 pieces (working out to about 0.15 each). Sounds
like a great deal for those wanting to experiment with replacing those darn
mechanical keyboard contacts on Minis, Odys, etc. Could be a good candidate
for a group buy (or bunch of group buys) where two or three people go
together and get a bunch (even if three people go together, they each pay 13
bucks and get 88 parts). The only thing is, I can't find a data sheet, so I
have no idea of performance, size, etc. Anybody got any ideas?
 They're also selling these on eBay
