Default 1xAA Blu-Ray from Ebay

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:

Sure thing, here's the link to one he's selling right now: http://cgi.ebay.com/ws/eBayISAPI.dll...ksid=p3907.m29

The seller's name is lsing2. I asked him some questions before purchasing it and the guy was really nice and responded quickly. He even sent a follow up email after I had received it to ask if I was happy with it.

1xAA? I didn't think lasers could run on just one AA? Unless there is something different with blu-ray diodes... (though I do see there is a drive to up the voltage).

Seems like you got a pretty sweet deal there apex007

I forgot to mention that I do have that flashlight, if anyone wants i can take it apart and see what kind of voltage and current the boost driver is putting out.

It looks as sturdy as most 1xaa cree flashlights on DX. The anodizing looks perfect and there are no noticeable tooling marks. The coil spring in the tailcap is a little flimsy compared to a Fenix, but doesn't detract from the looks or function. The switch is a standard clicky. The rubber button is recessed so it can tail stand if you want to put the Blu-Ray on the floor and dance around the beam with incense sticks or something.

Lol, i was joking. With a regular alkaline the driver is putting out 4.46 volts and with a sanyo eneloop it is also putting out 4.46 volts, now does anyone know of a good way to measure current?

The light is really nice, its not very bright but since its being taken apart that doesn't matter, the tail switch feels nice and gives a nice click so you would know if it accidentally got turned on, the anodizing on mine is perfect haII, so it still would get scratched up after awhile but not as bad if it was powder coated.

The reason it can run off an AAA is because the flashlight used has a boost circuit. It steps up the voltage so that it is high enough to power a blu-ray diode.

If this is as easy as removing the LED emitter and soldering in the blu-ray diode, then we could be on to a really cheap setup here. $6 for the light from DX, and $10 (+$15 for shipping) for a busted XBOX 360 Blu-ray drive from Tech Graveyard on Ebay. Add an Aixis housing, some Eneloops, time to assemble and we're at what, $40-$50 for a completed Blu-ray unit? That's dirt cheap!

Hi Apex007 thanks for the reviews and eBay feedbacks. ;D

Nothing made me happier than knowing that you appreciate something I made.

BTW you need not worry about killing the Diode; I just discovered the Diode can take some much more current.

Thanks Again
