Hi, I was searching everywhere but i was stuck at the pl520 55mW and the massive 2W unit. I saw that the pl520-b2 was listed as 90mW, but others say its 55mW... Does anybody have a component number or place that sells 100/200mW 520nm diodes if they even exist? I heard Sharp was planning on...

this is my build i made 2 months ago. its the coolest build i have made so far. all exterior components and some interior components are machined by me. including the host, tail button, and Host is made from stainless steel. this laser is watertight, shockproof, fogproof [like purged...

Its been a long time before i made another build. I made another green laser, i found enough time to make another one! Took me a while tough as it kept breaking and condensing. And i had to machine all the parts including the host. This is a very bright 532nm stainless steel green laser pen...

I decided to build another laser. This time one that could be used on a rifle. It was hard. This laser has 2 removable circuit boards, a swappable diode and lens assembly, it runs on a 10280 battery and can be disassembled completely and assembled within 5 minutes. And the lens surfaces on the...

I made a perfect 8mmx1mm glass which fits perfectly inside the laser focussing knob and on my 150mW bluray. I sealed it off with a special silicone film which i later cut out when the 8mm window was installed, which leaves a o ring where the edge blocks the window. Then i screwed it on my lens...

I got a sld3232vf 405nm 50mW diode. Normal current is 60/70mA for 50mW. Now with that current i saw a little square noise around the dot with the lens. Now i got the output on 140mA, the square is gone. I have heard that a diode generates more optical power at lower temperature so i tested it...

I want to fill my laser optics with nitrogen gas. The reason is, my lasers are watertight including the lenses, the entire cavity is sealed, even around the diode. But i have a major problem As soon as i put it in the car and turn the Anti fog and heater on, it condenses like crazy inside the...

I made a new laser, this one is for BobMC, i hope he will enjoy it! Its a stainless steel pen laser with a phr-803T diode in there set at 100mA. It is powerful enough to ignite fireworks fuse trough coated double pane glass and a car window. The fluorescence is bright and i could see the beam at...

Hi, i was thinking of replacing the diode of my laser. I got a 405nm laser. I made it watertight, but at the same time, easy to swap diodes if it dies. But i want to get a 50mW PL520 osram diode. Now, the driver board and BMS controll circuit is something hard to replace in this laser and...

This is my new stainless steel water resistant laser, i machined the entire host on a lathe, it was hard. Then i put an brass screw ring into the hole, the brass screw ring comes from a cheap ebay green laser. It took me 2 days to machine the host. Then i pressed my module in, this was the...

Hi, i got some questions. At the end of this year, i want to build an unique 1W 445nm pocket laser (very, very similar to the 405nm build of mine in terms of size and functionality). And sell it on the forum So the hosts is 90mmx15mm. (Exc the focussing knob and lens) I can fit everything (with...

Hi, a couple days ago, i zapped my 405nm laser with a piezo, after 3 times, it died:(. I know its stupid. And that sh*t happened while i'm going on vacation next week. No way i would get a new diode by then. But i found some usable laser parts from 2013 and 2012. And i thought, why not make a...

hello, i successfully completed an pocket laser burning pen. It had an SLD3232VF 405nm 50mW 5.6mm laser diode. Case negative. And here is what happened. (Yea its pretty dumb) so i had an piezo electric device extracted from an lighter. And an fully builded laser burner (aluminum host). Now, i...

(Pictures below and in the comment section) Hello, I do like to show my build on this forum. It took me more then 10 hours to build and design it. Finally done. so these are the components that I used for this project: Driver system: battery BMS, 405nm ebay laser driver, playstation 3...

hello, i'm searching for an IC similar to an 555 timer. But all in one. I need a pulse generator with an frequency of 2Hz and a duration of 200ms or lower. Is there an IC for this? Or anything near that range? Edit!!!!! A hall effect sensor is also alright!, but i need a hall effect sensor (or...

hello, i'm building a small laser which contains a good amount of components, i got a thread of it in the blu-ray & violet section if you are interested. now, i'm searching for an battery half the size of an AAA. Or a A23. But it needs to be 3.7v and lithium rechargeable. I can't find anything...

hello, i'm 16 years old, i live in Holland. i love to build my own electronic devices. I design electronic circuits. I made my own BMS controlled laser driver, with a shock switch as security measure so no one will be able to operate this laser unless they know the order to turn it on. Laser is...

Edit, the laser is completely done now, pictures will be added today. Thanks everyone for assistance! I got a 405nm laser diode driver (0/250mW) battery BMS (management circuit) and a safety switch soldered on a laser diode board. To turn the laser on, there is an on/off button on the rear of...

hello, i got an KES-400A laser diode. I know it not a powerful diode. But i really want to use it as this is going to be my first advanced blu-ray laser pen build. I got a very small aluminum led light hosts which i got back in summer 2014. I got a 3.7v aaa size battery, aixiz housing. 3 diode's...
