Do you think I can get Lifetime17 to build me host big enough to hold all of this? Forget a 100 W Nichia diode array. A portable laser induced Fusion device is the ultimate laser pointer and will be my next project. I wonder if they got their laser drivers from Lazeerer?

It looks like our own DTR has signed a contract with the Israeli Defensetge Force (IDF.). You better buy them while you can. Additionally, don't bring that DJI drone to Israel. NUBM44 in Action

I want to purchase a bunch of c lens pairs from them. Anybody know if they offer a discount?

Below is a picture of the 405 beam. Notice something that looks like dirt on the lens. However, it is not dirt on the lens because I get the same image when I remove the primary lens and create an image on a gray background. I could not take a pic. I tried using air to see if if was something...

You may recognize Survival Laser's stainless steel host. I have a bunch of them. They are great for beginners low power diode builds as is the S4X for higher powered diode builds. The only thing as I have mentioned before is I prefer to separate diodes from drivers by connectors to make...

The Chinese soldering station I purchased on Amazon finally started giving me problems. The soldering pencil replacement is no longer available. Anway, I have spent a lot of time researching different stations. All of them have complaints of one sort or another. I would like to know what you...

I know these can be sticky. I have not used it for awhile. While turning it back and forth trying to loosen it up, it is now stuck with the moveable lens in its furthest outward position. I can't get it to move twisting it either way. Any ideas. I guess it was never lubed property.

For the past several years I have been a guest at DARPA and had the opportunity to develop a Laser Assusted Particle Accelerator. It is a prototype for the Department of Defense and will most likely be deployed in some form on Navy vessels. The details regarding development are of course...

This is for a NUBM44. I want to put in cylindrical lenses.

Lifetime17 has driven this diode at 1.2 to 1.5 amps. I understand others have lost the diode with less current, that it may be a driver issue. Survival Laser sells two drivers that can be set at these values. Does anyone have any experience with either of these drivers? Driver 1 Driver 2 Since...

So, I got to thinking, a 3 cell 32650 build with a big ass heat sink is all well and good. It is so heavy, you can use it as a batan skull crusher in a pinch. But, suppose you need something more portable... never know when Antifa might darken your door, so a portable light is in order. It...

I have experimented with a number of ways of dinner this and I am always wanting to improve on previous builds. One thing I feel is important is to be able to easily troubleshoot problems which is difficult if the driver is soldered directly to the LED pins or if the build uses very short wire...

I was in remission from my laser addiction but recently relapsed. I have 2 maglite mods that were done by Jayrob including his battery monitoring module. They are both two cell for a 32650 battery. (I have several of them.) Recently I noticed when I had an sxd on my dummy load, that with...

I realize this is not about Lasers but after years of work, finally, in a joint effort with my collaborators at DARPA the office of which a picture is below, achieved perpetual motion with a modified Sterling Engine design that does NOT use temperature differential. Perpetual Motion No...

I have a number of PSUs. Linear and switching I use for my Amateur Radios. They are working. One of them I made with 2 modified HP server supplies in series. I get 24 v. I connect this to a Chinese dc to dc buck converter. It has a display and had a cc cv functionality. I put an ASC 4500 on...

I have only used it a few times. I have other expanders and never really needed it. Best offer plus shipping which we can discuss. (Insured of course.) Payment via PayPal.

I understand that DTR, AKA Jason is out of pocket. Who is minding the store? I needed some help something and sent email to info@.... which is the email address on the site. Is this correct?

Hi Guys, I have not been around for a while...getting old lol. Is DTR AKA Jordan alright? I see he has not been here for a while either. Last April a documentary about my grandfather, Hugo Gernsback has come out of post-production but COVID has prevented its release and distribution. If it was...
