hi guys, i wonder for a while why do we we all have all those powerful lasers, but if we want low powered one we usualy build another one.. i decided to combine the two in one package by slide switch to vary the resistance of the shunt resistor. high power drives 260mA to the diode which is...

hi guys i am in need for 532nm laser module that can be run for longer period of time. idealy i need just smalest possible module that i can place in heatsink of mine with apropriate airflow in mind. i wonder if you can recommen me some?? there is a lot on ebay and ali, but i doubt those...

Hi guys, i just want to share my latest build that is not your usual one. I have access to lot of tools as my father have them all, but one thing i am missing is lathe. Ability to shave metal with lathe is what i miss to make builds like yours from scratch. Especialy heatsinks, and be able to...

hi guys i am sure you are familiar with this driver, i would like to ask you if i need to change some resistor to get full 1.6watts out of it..?? as mine gives me 300-600mA on a dummy load, with potentiometer all the way left-right.. something isnt right.. The driver closeup:

hello guys i just would like to know if it is viable option to use signal generator as a simple switch in front of actual laser driver.. see picture. would it work fine, or is my thinking completely off. all i need is 1- 30 hz. so slow blinking basicaly. thank you

Not much to be said here, just to show some nice build. as the title describes the colours, the driver is set to 210mAh.. host is standard brass pen sanded to be completely polished and painted. beamshot comparison with 488nm cyan

Hi guys, I have done tons of research, yet still i wonder, which blue diode can give the best smallest diameter spot focused to infinity. I am sure you will have some on hand experince. Obviously lens will play a huge role but in general what diode is best for that? Single modes are out of...

hello guys i wonder, is this lens any better than classic plastic one? seems like it limits some light to be passed through ???? dont know how to describe it.. like plastic ones have not so narrow hole of lens housing on the back side wchich goes to the diode..

hi guys. nowadays laser pen hosts are 13mm inside diameter. it used to be around 12 for our classic "aixiz" module. so what are options for filling that space between LD housing (aixiz) and host so it doesnt rattle inside and heat can be spread across host body. i did my research and...

is there any difference between those two mint colored diodes? from my research i found both are 35mW both should run at around 100mA but i also found you drive first one up to 250mA and getting over 100mW. so my question is about second one as there is not much information, but if i...

Hi guys Wonder if anyone dismanteled laser pen that has battery built in? Host looks nice so i would like to not damage it, also if possible to save the driver. Is there aything that makes it tricky to dissasemble, if you have exeperience with those.. ?

hello guys, after around 12 years i rediscovered my old hobby. found out there is a lot of new beautiful diodes, so i couldnt resist just to start ordering them. my first project 488nm pen: i started by dismanteling cheap 5mw violet laser to extract a driver. after connecting it to dummy load...

Hello guys. I just tried to polish my pen style host for a future build. It is nice, goldish, shiny. Do i neet to treat it somehow, will it corode? I dont know what material it is, i am sure someone tried it before.. Any sugestion?

Hi guys, this is my first rewiev so hopefully it will end up well lol. I have ordered some green lasers from Buyincoins and since they shipped my stuff it was really quick in my box. Really. I was impressed, but unfortunately what was before they shipped my stuff was terrible. They were unable...

Hello guys.. i have one storry. I have an advertisement on the web where i am selling laser pointers.. Today i received an email where one guy wrote me this: selling lasers above 5mw is illegal.. you should remove your advertisemet. The trick is that i am totally unable to find out if my...

hello guys i have ordered some stuff from focalprice couple of weeks ago.. It was 2x10mw green pointer and a spy pen camera.. today i recieved a letter from customs post in my country that i have got a parcel and they need me there with my - ID - some documentation about my payment - and...

Hello guys i lived in UK couple of months ago and i created an paypal account in order to buy a stuff from ebay and all over the internet... now i am back and i live in my country Slovakia, and i would like also use a paypal, but i dont know what i should do.. i have an bank account here in...

hello guys, have anyone seen this drivers??? http://o-like.com/b2b_cpinfo.asp?id=987 i must to be honest i dont understand this poor specifications.. could anyone bring a light to this for me?? Is this driver usable for us??? it seems a great deal thanx in advance

Hi guys, how are you doing.. Recently i have done my first spirograph, and as i am total lama in building some circuits i have a little problem with my build.. I used socket adapter as a power supply which give me 3V and 1000mA.. it is enough to drive 3 small motors.. I have used 40-ohm...

hello guys, i have seen couple of threads about yellow lasers which are made by combine green and red laser.. i have just one unsolved question. what RATIO should be between this two colours?? i have seen Rog makes one prety yellow beam from 5mw green and 5mw red. is 1:1 ratio enough, or do...
