One of my suppliers can get me the new 573nm modules at a very reasonable price. However, the minimum order from the "crystal factory" is 50pcs. If enough people were interested we could do a group buy but I'm not sure I want that many right now. I also feel like they are going to become a lot...

I've been selling laser components, assemblies, accessories and other small electronics on eBay since 2016. In that time I've come across quite a few scammers, liars, morons and just all around garbage humans. Every time someone does me wrong I add them to the list of Blocked Buyers...

Looks like Sanwu just released a new X5 Beam Expander. Same threads and adapters as the X3. I will be getting these added to my inventory ASAP! https://www.sanwulasers.com/product/x3beamexpander

I recently purchased this Laser Flashlight - https://www.ebay.com/itm/204347636854 The size of this thing is massive and it's very heavy. It's powered by four 181350 batteries which are just two 18650s in series. I decided to compare it to an XHP70.2 LED flashlight I have and it gave it a good...

At last, I've procured replacement diode caps that will hopefully work to replace the "G-Ball" lenses on certain diodes. I'm hoping they will just press on snugly after removing the old lenses and won't require anything to keep it attached. I will probably have to modify one of my diode presses...

I've just received a new shipment of copper diode modules. These have a few extra lens threads so the G-8 Lenses work better than the older standard versions. https://www.barnettunlimited.com/product-page/z80-lasers-xt-12mm-copper-to-5-9mm-laser-diode-module-w-glass-lens-options

Just did some testing on these new diodes I got and all I've got to say is H*LY SH!T!!! (pardon my punctuation) These are rated for 3.3 watts @2.2 amps but they go much farther than that. I pushed one up to 5.5A and it didn't kill it. My LPM read over 8.2 watts of glorious violet photons. The...

Would it be possible to add rumble.com as an approved site to share videos from? I prefer to host my videos there over youtube.

I bought this new 20-Watt laser engraving module for R&D. I took it apart and photographed it each step of the way. I put it back together after and I'll probably put it on my CNC machine at some point. Full Album: https://ibb.co/album/nsC2tf?sort=name_asc&page=1

I've been tinkering with 3D design a little bit and decided to make something useful for the community. After a few tweaks and some trial and error I have working designs for both TO-5 / 9mm and TO-18 / 5.6mm laser diodes. Since they're made from plastic they're certainly not as durable as the...

G-Ball Adjustable Lens Adapter Add adjustable focus to your fixed lens "G-Ball" laser diodes. This adapter will thread on to most standard diode modules that accept M9 x .5 lenses. You can now use an adjustable lens to correct the focus of your laser diode. Most standard M9 x .5 lenses are...

Just came across these. Likely the newest version of the NUBM44's.

I picked up a few of these little guys if anyone is interested. They can be pushed upwards of 80 watts. They're $175/ea +shipping. Not for beginners! I accept PayPal, Venmo, Cashapp and Crypto. Please let me know if you have any questions.

Unexpectedly came across these diode blocks while taking apart a projector today...

The NUBM34 Laser Blaster I decided to build a laser blaster using the NUBM34 laser diode array. This thing is insane! I ran two rows of diodes in parallel to the other two. Powered by a Milwaukee 18V battery pack and this is the boost driver I used...

I have a few of these brand new diode blocks that weren't removed from projectors. They don't have tinned pins and have never been used whatsoever. These are the latest version of the NUBM44 diodes. I am only offering these on LPF for now. I can do individual diodes for $75 + shipping I can...
