I went to the store early this morning to get the drive and then to Lowe's to get some washers.

I decided to use an MXDL as a host because I had some Ultrafire 16340's that max out at ~4.2V when fully charged and that is right in line with the lavadrive. ;)

I set it to 70ma and it runs great!

I resized the pics to 1024x768. If that's too big, buy a new monitor. :D As others have said before, the camera simply does not do these justice, especially when fluorescing minerals.

Build one, get the rocks and enjoy!

This shows the lavadrive connected. You can see a piece of heat shrink tubing I used to seal the driver after it was adjusted.

The battery with the "spacer". I took the edges off of the bolt head w/a dremel and it fits great.

Lighting up some minerals. :D

My DIY meter only shows 5mW. :-[ I think it's not very sensitive to this wavelength.

Hmm, that's weird. Kenom's meters are very accurate and can measure 405nm better than a lasercheck. Since you're basically using the same thing I think it should be pretty accurate. Maybe the laser really is putting out 5mW. ::) Who knows? :-?

He didn't say it was a Kenom. Milos' Lasercheck measured my unit at 14mW. The Kenom measured it at 26mW.

My Lasershopuk unit came labeled at <5mw. It tested at 11mW with the Kenom

You really need to wait until dark to look at the rocks. Even then sometimes the "blaze" from a direct hit overpowers the fluorescence of the stone. Wait until dark. Light the rocks from farther away. Also I've found that you get a different look if you use a diffraction grating .

Peace,

I took some of the better ones to the closet and shut the door. :D

I have to admit that I may be in error regarding the current. If you have seen a pic of Dr. Lava's drive you know how small it is. No one was around when I was measuring it and I had to try to hold the leads on the tiny SM resistor and then look at the meter. I think I saw 680mV several times but every time I looked away from the driver the leads would slip off. :mad:

He said his DIY laser power meter. Which is the one that uses the thermal heads from ebay which are no longer available and is basically the same thing as a Kenometer.

rossoco its not your meter. I have a DIY, and it showed 5mW untill I upped the current by alot. every diode is different. try pushing yours a bit more. can you see the beam in the dark?






EDIT:


I dont know, but the low power may be from the fact that its an XBOX diode.

I'm pretty sure at 70ma it's not from an older xbox drive, since they would pop at 40-50ma

Take a look at the sled the diode came out of. If the part number on it is PHR-803T you have one of the higher power diodes. From my measurements at 70mA, you should be getting roughly 50mW out of it. Of course it will be less after a lens and especially if it is AR coated for red which is what most laser optics are coated for.

haha, yeah these newer xbox360 addon drives seem to have really beastly diodes in them. im waiting to get some new ones in so i can test the max we can push them to.

I just cranked the pot and now get 24mW. ;) I guess it was turned way down. :D

that sounds about right after the optics. I think I was losing about a factor of two in power output. I'm currently trying to get quotes for AR coated optics for shorter wavelength light like the 405.

I'll have to dig it out of the trash. ;D

The beam is visible now.

sounds like you are the lucky owner of one of the beastly diodes. [smiley=thumbsup.gif] I can't wait for my host to arrive so I can put mine together.
