Hey guys, So it is time for me to get serious about firing my little SSY-1 Yag-laser. I bought the Laser-head with Q-switch, the original "pulse-forming network" (capacitor-system) and the trigger assembly from Meredith Instruments some time ago, but I have not had the time to play with getting...

This is a RF-powered CO2 burning Laser-rated 5-7W, minus the 30V power-supply and 5v signal power-supply, (wall-wort). I bought this in the GB from Heruusciences a while back. Some of you may remember when these were offered...

I just seen this offer from Electronics Goldmine. They are offering boxes of LM317 regulators 900 pcs for $153. Great price but that would be a lot of DDL-drivers :) Factory Box of 900 National LM317T Adjustable Voltage Regula-The Electronic Goldmine

I am looking for some 14mm-15mm (.550"-.600") diameter contact-boards for my heatsinks. These would just need to be simple round-boards with a copper-pad in the middle to contact the battery-anode. even better would be to have a small-hole near the pad in the middle to solder a wire to the...

I have built special heatsinks for one of my customers for almost a year now. I have finally had a chance to play with the lasers he has been building with them. OK, so this mod is made famous by our friend KipKay, the main difference here is that these are done with proper drivers, heatsinks...

I bought a few Aries-type lasers from Glenn's LG-group-buy last winter. One was very different from the others in design, it was designed to unscrew in the "middle" of the body to replace the battery, (instead of removing the tail-cap). Also, it was designed to take a 18650, instead of (2)...

Dark Horse and Dark Lasers To all LPF-members: It has come to my attention about some confusion about my affiliation with "darklaser.com". I have recently had several newer-members assume that I was somehow part of this other web-store. I cleared the issue with them, but just the last few...

Hello everyone. As many of you know I have been really busy this last-year starting a up machine-shop. This means I have less and less time to play with lasers :( I hope to change this soon, but I have decided it is time to reduce the number of projects on my plate. I will be selling a few very...

I just wanted to let everyone here on LPF. In honor of our new web-site, we are having a 20% off sale on all existing inventory. Dark Horse Custom We have a limited-number of DJR-kits available (host, heatsink, battery, Aixiz-module), lots of "DJR-Full body V2 heatsinks" for the Dorcy Jr build...

We have finally made a run of heatsinks for your pen-laser. These are made of carefully-polished 6061 aluminum and anodized in either "clear" or "black", custom colors and patterns are available by request. To use, simply slide over the aperture-end of your Leadlight, CNI, DX, or other...

The first batch is complete, much more to follow :)

I thought I would let everyone know, all the products at Dark Horse Custom are reduced 10% for December. I have also added a couple of "build-kits" which will provide everything except the diode and driver to complete your choice of two-builds. Come check it...

It looks like Sanyo has developed a new 405nM burner-diode (12x), capable of 450mW of CW "lasery-goodness". Next-years group-buy? http://www.electronista.com/articles/08/10/06/sanyo.12x.blu.ray.laser

This GB is now closed, we were able to order a total of 12 pairs of ML-7 goggles, thanks everybody!! http://mysite.verizon.net/grall/darkhorsecustom/id71.html “The problem” Like many "laserists' here on the forum, I play “work” with some powerful lasers of different wavelengths and need to...

Does anyone have any experieince with the diffractive gratings from Dragon Lasers? They sound like they are good qaulity, glass with aluminum grating, so they should hold up to more powerfull lasers. They only have 2- designs, 2D matrix and "fan", but the kit comes with each in a "pass-thru" and...

I found these this morning, seems like a good price for a complete HeNe set-up. It is smaller than the one I have, .5-1.3mW, .8mW typical, but this one seemed like it was worth it just for the PS. I think I know what my daughters science-fair project will be this year ;). I have no affiliation...

Dorcy Jr Heat sinks Available Now! Order page is now up here:  http://mysite.verizon.net/grall/darkhorsecustom/id47.html Due to popular demand, I have produced a large batch of aluminum heat-sinks for use in the Dorcy Jr modification. These are precision-machined on all surfaces from "billet"...

So I worked out a deal to build a laser for another forum-member, (the particulars of the deal are unimportant), but I as built this laser, I took several pictures, so I thought I would share them here also. The build is not really anything too exotic, the host uses 3x10440(AAA-sized rechargable...

So I was repairing a loose connection in one of my Dorcy Jr/Senkat mods last weekend, (thanks Kenom ;D see original construction here:http://www.laserpointerforums.com/forums/YaBB.pl?num=1181635652),and a long held curiosity got the best of me. I always add 5-ohms to the Dorcy Jr, (available...
