I got some amazing 5W 450 lumen 3500K GU10 base LED bulbs to replace my office track lighting from DX. I got 4 bulbs for less than what local retailers charge for one low power accent LED bulb. My room is considerably brighter and the color rendition is really impressive. Sometimes gotta give...

Umm, you may want to consider how the prosecution may dig up your involvement on this forum and any statements you may have made, including your signature that claims you have a 1000mW and 500mW laser in your possession. Depending on how zealous the prosecutor is, he might be aware of laser...

My collection. The HeNe is one I picked up at American Science and Surplus back in 1988! Still works like a champ. Back then I was in high school and did music driven X-Y laser shows in my parent's basement. Good times. The weak 532 I bought from Intelite back in 1998-9-ish for $250 I think. The...

Thermite would get the job done a lot quicker and cheaper :D

Apparently it's common knowledge that the PHR-805 is a case negative diode and that the Micro-Boost driver is probably not the ideal unit to drive it, except TO ME. After years of service my ONLY laser project to date, a beautiful stainless steel CREE C3 with a PHR-803T, went LED on me. It was a...

I am attempting not to LED any more diodes like I did in this thread: http://laserpointerforums.com/f38/phr-803t-new-build-not-lasing-71027.html This diode is now the newer PHR-805. I also got a new MicroBoost drive just in case. I also built a bench driver based on the LM-317 regulator and I...

Mmm nope, no LM317 handy, no test load either. Both necessities I will be getting soon. Bit by not RTFM. Assumptions are the mother of all f***ups.

No I didn't. I bent the case pin down to meet the negative pin and soldered both to the D- driver output pad...just like I did on the older first build. I of course did not read the Microboost manual thoroughly. I guess the damage was done because even lifting the case pin from the circuit did...

I did not use a test load. I paid for a driver that was set to 120mA from a member of this forum, so I trusted his expertise. I was planning on a drop-in build in this instance. My last PHR-803T build used a Flexdrive v4 set to 120mA by DrLava himself and it worked right the first try and kept...

I am reconstructing my old Blu-Ray laser with new parts and I am running into the issue of the diode going LED from the get-go. I have a new Microboost driver, new PHR-803 diode, and a new 14500 battery fully charged. The Microboost I got from Flaminpyro was set to 120mA and the diode from...

I thought I'd take a crack at this build...seemed cheap enough. Of course when I tried to remove the little driver pill, the leads going to the LED just popped off the circuit board and rendered the driver useless. I examined it to see if I could repair it, but the little traces snapped where...

In light of these comments, I decided to cancel my order. Any suggestions as to with whom I can purchase a boost driver from? I'm repairing my older PHR-803 build that I had running with a single 14500 battery. It would be nice to get the current preset to 120mA. I've got everything except the...

Great, sounds like a hassle. So my choices are join another forum and chase him down, sit it out and possibly wait weeks or more until he can fit one of his customers into his busy schedule, or cancel my order and start all over again. Fun.

I recently made a purchase from Moh and I am quite pleased as well. Keep up the great work!

Any idea what the turnaround is on Dr. Lava's drivers? I ordered a MicroBoost Drive (shows "In Stock") on 12/16 and it hasn't shipped yet. I e-mailed, but there is no response yet. I have a build waiting on this and all other parts I ordered the same day or later have arrived. I searched this...

Looks like the 1.25s are sold out...darn. ***UPDATE*** Just purchased a driver kit and a heatsink. Off to find the Aurora C6 host! Thanks Moh! -rcpa@xx.xx.com

I used my 405 to do all kinds of neat fluorescence and phosphorescence experiments. It's one heck of a way to charge anything that glows in the dark. My kid has a ceiling full of those glow in the dark stars and every night he wants them to glow before bed. I set the focus to super-wide and...

Back in 2009 I built a laser with a PHR-803T diode mounted in an aluminum sink and a MicroFlex Drive V4 (preset to 120mA) with Aixis optics and all buttoned up in an Ultrafire C3 flashlight body. It was powered with an Ultrafire 900mAh LC14500 Li-ion battery and it has worked flawlessly for...
