    where can i buy a complete Laserhost for 2x16340 battery?

    @Lifetime17, thank you for your offer, friend, but i made up my mind now and im gonna build my own casing.

    where can i buy a complete Laserhost for 2x16340 battery?

    thank you...im just looking through driverboards on ebay and it seems they all need 12V input..at least the stronger ones, that im looking for? Well maybe im gonna build my own host, its not that difficult after all. looks like im gonna need 3 batteries.

    why do Laserbeams stop "suddenly"

    hello, ive asked myself a couple of times, why my Laser has such a short beam....the strongest one i have is a 1500mw Blue Laser, now i cant say how long the beam is, might be 2km or only 500m, its hard to tell...in any case, the beam suddenly stops, it doesnt get weaker or thinner, its bright...

    where can i buy a complete Laserhost for 2x16340 battery?

    Hello guys, i deceided i want to build my own lasers now instead of buying complete ones. Thing is they are very overprized in EU and US and if you buy in China, you can get some pretty good deals but its hard to find anything more powerful than 1500mw blue lasers... So what i have in mind is a...

    building a 5W laser with a Laser that comes with a 12V PSU

    one more thing, i just figuered out that i got 2 unused battery-packs for handheld akku-drillers here. It would be nice if i could just use them, because they are already in a nice black casing...one is 18V and one is 14,4 Volts. What would happen if i put the 14,4V on the driver? can it also...

    Hello from Germany

    well i dont use Googles? I know people use them for burning stuff but i wanna see the beam...why should i burn things with a device that can blind me, pretty uninteresting, i prefer a gas-torch. the googles that came with the laser...the ones that look real sketchy and can be bought for...

    9V battery mod?

    do weak batteries also affect the output power or only how long you can use the laser before recharging? isnt the drivercircuit supposed to always create a stable and defined output-current?

    Hello from Germany

    thx for letting me know its not a social forum, you may not believe it but i didnt expect it do be :) I just saw the "Welcome" thread and felt a little obligated to use it. Yes i knoe the 303s but its not what im looking for. Going from 1500mw blue to a 80nm doesnt seem to make much sense to...

    9V battery mod?

    Hello, excuse me for making my 4th thread on my 1st day, but ive got a lot to ask and i dont like to put all in 1 single thread. I was wondering how convenient it would be if we here in Europe could just use the regular 9V batteries. The have a little bit more power, you can get them...

    messing with potentiometer on Blue Laser?

    Hello, i screwed off my new 1500mw Blue Laser for the purpose of putting some Thermal paste between the diode and the casing and on the winding. i got excited when i saw the little potentiometer on the driver circuit, because i saw on Youtube that the power can be increased pretty...

    Hi, my name is Arthur, im 40 and from Hamburg Germany :) i got interested in Lasers by stumbling over a styropyro video like many more i guess. I gotta admit i wasnt even sure if lasers like this existed anywhere else than in science fiction films, let alone they were available for so cheap. How...
