@FAP thank for your advice! I ll try to balance between my needs in terms of beam power and the reduced current! I hope it will run i want to!

That's so nice to hear bro! I hope my project will last enought to be considered successful!

Hey guys, i want to use my NUGM02 1W+ attached on a tripod for taking leveling measurings in distance. That means it will have to stay on for about a minute some times. The recommended current of the seller is 1.7A max. It will sit on a custom host with, i believe, a serious amount of cooling...

Guys one more question. I have this laser... A cheap green AliExpress one... Any idea if this tailcap can handle 1.5A or max 1.7A? How can i figure that out? I ll make a host of my own and i d like to use this tailcap switch...

Ok Gianni! Business with you is great so far!

I m thinking 2 x 17mm and 2 x 20mm @Shmackitup... Send me the approximate cost for these! Thanks for the reply btw!

Hey guys, i m about to make my own host and i m looking for a blank battery contact board like the one that survivallaser selĺs. I was about to buy from them but when i saw the shipping for Greece i almost had a heart attack... It was about 45usd shipping for 2 boards and 2 driver pills... Any...

The reason i wanted to use 18650 is because i have a lot of them... Maybe 30-40, all of them good cells, taken from powerbanks of xiaomi, anker and Huawei... So that's the reason... However i finally ordered a couple of 18350 pairs and i ll try that way!!!

And any idea which boost driver to buy in order to use with NUGM01T? I want to use a single 18650 battery housing from a broken low power laser... I know where to ask for bucks but no idea for boost!

Ok guys... I fixed it... I m a noob at this sorry... I thought that i had to have the lens fully threaded and tightened... However the sweet spot for the minimum beam diameter is about half threaded... Now it 's great!

Lens are brand new @gazer101 . And the threads of the lens are fully screwed... So what have i done wrong? 😓

Hey guys, this is my first attempt to build a "powerful" laser. The diode is a Nichia NUBM4B 4.7w, bought from techhood on Ebay. I m using a skyray led torch for the housing. Really spacious for a newbie like me to work! I m using an Astral superdrive V as a driver at 3.6A and G2 lenses. I...

Hey guys, after i completed my 4.7w blue laser with a NICHIA NUBM4B i want to build a less powerful 1w+ green laser... But i m confused which diode to buy... Do i have to find a powerful Ir diode that will use special lenses to produce the green colour or are there diodes that will give green...

@FireMyLaser today finally the MOSFETs and resistors arrived and i tried your circuit! And yes ot worked! Thanks man! But i have one question... How do i choose the correct resistor? What does it depend on? For example i used an 1ohm 1w resistor and it worked.

I ll be around bro! Thank you for your time!

@FireMyLaser i have one last question... It s about the gate voltage... Which parameter shows me at which voltage the diode is on and the current flows rully? VGS, VGS(TH), something else? I know that the diode can open so the current to flow l, but not necessarily, completely. I hope that's the...

@FireMyLaser it will be a 1.6w diode osram pl450b with astral superdrive v... It will run on 18650 in series to have the recuired voltage... I m planning to use a boost driver at some point because it will help me more with the housing, to have the batteries in parallel... So 4-8v... But in the...

@Encap i have already ordered a ton of things from ebay, alie, banggood etc... Switches, cables and whatever 's coming in my mind that i may need... Of course i ll drill a bigger hole if I can't make it with the mosfet... But i want to minimize the hardcore "modding"! @FireMyLaser i agree with...

Thank you so much @FireMyLaser ! I 'll try that for sure! And of course i would appreciate if you could suggest a mosfet for the job... I actually don't know how much current will the Astral driver need from the battery to drive a 2W diode but i m looking for a 5A mosfet... No idea if it s too...

Any idea of a push switch that could handle such current? I can even drill a larger hole on the housing...
