I recently purchased a DIY Blu-Ray from Ebay. I don't know who makes these as I've never seen anything similar here on the LPF boards. I have wanted a Blu-Ray for a while, but don't have the time to make one and wanted something that ran off of standard batteries.
This is powered by 1 AA Sanyo Eneloop battery. Two batteries were supplied and the seller claims that it is putting out about 10mw at ~40ma. I have no way to verify this but the beam spot and qualities seem the same as other Blu-Rays posted on LPF from other manufacturers. The seller does warn in the included instructions that use of any other type of battery than 1.2v NiMh batteries will kill the diode.
I'm assuming there is a boost circuit similar to the dorcy flashlights powering the diodes with some modification. I was so impressed with the construction that I do not want to take it apart and risk ruining a great little pocket blu-ray. The diode is obviously mounted in an Aixis housing which is mounted so that it is slightly below the rim of the bezel. A piece of thick plastic closes the opening nicely. A plastic cap was supplied that fits perfectly and protects the lens from dust and debris.
The beam is visible in the dark with no added smoke. The pictures below that show the beam were taken in daylight, but only the camera was able to see them. They were not as visible as they appear to the camera. No smoke was added though.
So far it has seen about two hours of on-time and I have had no problems, just lots of fun. Although the Blu-Ray is no match for my X-105 or Pulsar, it is just so unique and fascinating that I find it worth every penny.
I put a Photon Proton Pro, Ultrafire C2 and Traser H3 Tritium Classic in the background for size comparison:

any chance of you posting the link to the finished auction?
