[Cyborg] 200 laser diodes

OK, I've placed the order.  We got 15 dozen, placing us in the highest 
discount category offered, go group orders!

I don't know how long DHL will take to get it here, but most likely 
we'll have them by the end of next week, certainly by the end of the 
week after that.  When we get them I'll send a message to this list (and 
noisebridge-discuss) about pickup.  I'm at noisebridge on a fairly 
regular basis, of course, but how does the cyborg meetup time (Sunday 
afternoons) sound to everyone for a group geekout and delivery time?

Also, buyers owe me money.  I'll take cash or paypal on delivery of the 
lasers.

Details from the order on the wiki:
