Here's the nutshell. You guys may have seen Styro's groupbuy for Nichia 40W 460-465nm arrays (here).
These arrays are very interesting. I have one in-hand. The challenge of course is what to do with an array of really unique diodes that doesn't separate or allow very good extraction. The answer, is to make the whole thing into a unique build. I've designed a portable host, that I'm going to have CNC'd, and I'll either do 1x (just for me), or do 5x / 10x (for a group buy). The obvious advantage of orders 5x or 10x is cost. CNC work tends to benefit from economies of scale. So I'm opening up a group buy to see if there are other people that want a host (and drivers).
This host isn't large. Its measurements are 126 x 70 x 32 mm. It's designed to fit 8x 4 Amp buck drivers, and 4x lipo cells in 2S2P config. Despite the small package, the electronics and cells will be capable of supplying the 32 Amps of total current that the 8x diodes require (here's 1x diode in a much smaller version of basically the same concept host: Photino 465nm @ 5W)
The host + driver is expensive, but the arrays aren't cheap themselves (those are around $650). Pricing includes:
The cost at 5x participants will be $270 USD each, plus shipping to you.
Tentative participant list:
1) RHD
2) Alaskan
3) Minamoto Kobayashi
4) Moe Ron
5)
Lead time will be 6 weeks. I have a decent amount of experience ordering these kind of CNC'd parts (the Photino, the Photino RGB, the MOD9s, the MODCs, etc) so I don't expect any of the hiccups that other CNC projects seem to run into on this forum). Also, the driver is dead easy. I've already ordered enough panels for 80x (just because it's so cheap for PCBs themselves) and my driver uses entirely north american sourced parts that are fast to order from digikey (and the driver is a design I've used in a dozen different shapes and sizes).
That said, I'm not going to wait terribly long if there's not a lot of committed interest up front. If there isn't, I'm going to go it alone on 1x QTY for myself. I'm really eager to build with this array, and am impatient. So if you're interested, make yourself known.
3D printed prototype (excuse the fast / low quality print settings). This is revision number 17:

- 1x host
- 1x host lid / trigger flap
- 4x nut and bolt sets for securing the array into the host
- 8x 4 Amp buck drivers w/ CNC'c heatsinks
- 1x high current mosfet trigger board
- 1x Mini-DIN 3 connector (for creating an external port to plug in a balance charging cable)
- 1x Mini-DIN 3 plug (for creating the charging cable)
- Neodymium magnets (intended to make the host lid removable)
The cost at 5x participants will be $270 USD each, plus shipping to you.
