Good morning everyone, I have a question regarding the efficiency of the ACS1500SE vs Micro Flexdive V5. I recently build a very small single 10440 driven laser and I am ruining into an issue where the 10440 can't supply enough power to drive the diode at the set current for more than a few...

Hey everyone, I have finished my 520nm Sanwu Pocket build! There were some pretty big challenges that were overcome during the build. Firstly, due to the super small size of the pocket series host, I needed the most efficient high power 520nm diode I could find, from all of the diodes I could...

Good morning, I had to modify the housing on a DTR G8 lens and I am worried that I have damaged it. The diode used is a 12X 405nm (can't remember specifically what one). Does anyone know what would cause this kind of artifact? The picture is of the dot at about 10m.

Good morning everyone, I am posting here to see if anyone could custom machine me a module. I have attached a hand drawn diagram of what I would need done. If it in unclear please let me know so that I can fix it. I am currently working on a cad model for it but I am learning it from scratch...

My little brother has asked for a telescope for Christmas. He is 10 yeas old and would only use it for very basic viewing. I know i got a telescope at his age and it wasn't that exciting because it wasn't very good and could only just make out detail on the moon and stars didn't look that...

I recently purchased an oscilloscope and just to test it out I made a square wave at 1000hz with audacity and displayed it through the cro. The output is shown in the video, not sqaure at all but I do see it is trying to be. My question is, is this because audacity cant make a proper square wave...

I am selling a 500mw (as specified by yobresal) pocket mini host 445nm laser purchased from yobresal about 4 months ago. It has had very minimal use and is in perfect condition. It uses 1x cr2123a battery (2 included with sale [1 protected, one not], as well as a charger). GITD cap is also...

I have a schematic for a circuit and the ic's pins are reordered (as usual) but this is a rather large circuit so I would like it to be as simple as possible. Is there any software that can be used to do this or any tip you guys can give me? Attached is the schematic i am trying to simplify...

ok, after seeing a few threads showing member's home built TEA nitrogen lasers I decided to make one myself. i have half finished the actual laser but have no way of charging it. I couldn't find any laser printers to dismantle to steal its HV module but had plenty of tv flybacks. a couple of...
