Notes for next LED bike light design
Ok, after discussing my light with several people, I've decided to order parts for a small run of lights. This is more to show people how to make them than to make any sort of money off of it. I'm fronting about $100 in hard to find parts and will let people find their own batteries, cables and such.
Parts List:
From DealExtreme:
SKU Qty Price Total Product Name
10421 1 $7.35 $7.35 8-Mode LED Emitter Driver (3.7V~8.4V Input / 2-Pack)
06901 1 $2.84 $2.84 iCON Current Flow VU Meter (500uA)
01445 10 $6.07 $60.70 Seoul Semiconductors Z-Power LED Emitter (U-bin) ZPOWER

From KaiDomain:
SKU Qty Price Total Product Name
2982 2 $3.44 $6.88 Highly Efficient LED Circuit Board (4V-18V)
3215 1 $12.99 $12.99 (5pcs) 7135 Regulated 1A 17mm Circit (16 modes in 3 group)
3236 5 $1.51 $7.55 20mm 6 deg Optical lens Reflector for Lumileds/SSC LED Bulb
3237 8 $1.40 $11.20 20mm 15 deg Optical lens Reflector for Lumileds/SSC LED Bulb
(Note that I ordered some extra items to match up with other current/future projects)
The main design that I'm considering making is a "Dinotte" style. It looks good and it's somewhat simple and easy to build, even if it's a little bit bulkier than it needs to be. An even simpler option uses 3 3/4" copper pipe end caps. It's smaller and probably a little heavier, but it will not have any overheating problems.
