    Building My First 7w With NUBMM44 V2 need all help I can get!

    I love this compact size bro! Exactly how I wanna build my next host! 2x 18340 batteries i guess?

    Maximize Nubm44 or any diode beam concentration

    @Sowee7 i d use some help with more infos about anamorphic prism! A link maybe? 😇

    Maximize Nubm44 or any diode beam concentration

    Hey guys i m playing for almost a month with my Nubm44 laser but i m annoyed with my beam concentration from the very first moment... Seems like the furthest the beam goes the wider it gets... What kind of optics should i use to maximize the concentration of that beam? Atm i think my lens is...

    New custom host NUBM44 build!

    Finally driver is mounted on the host side wall, with some kryonaut extreme 😂 for ic and some thermal epoxy on the whole driver to stay there... 40+ secs no blinking! I think it stays cool enough now!

    New custom host NUBM44 build!

    I think this is the best solution... I should have thought about it!!! Thanks for your help @Lifetime17

    New custom host NUBM44 build!

    I tried with a 2 part thermal epoxy but i also have to find a way to keep it pushed on the side wall of the host for about 2 hours until it cures... I think i ll try today and i hope it 's gonna work....

    New custom host NUBM44 build!

    Any idea what heatsink should i use for a let's say, duty cycle of 30s max? I think the one i used is far from being good enough for this job! @Shmackitup

    Question about this driver

    Finally i used my Astral superdrive v! I tested the P4000 and i was able to get up to 4.5A... However the modes are a little tricky so i quit!

    New custom host NUBM44 build!

    Hey guys this is my new custom host and a NUBM44 inside! I used my Astral superdrive v inside on full current, about 4.8A and i attached a small heatsink on the ic... I have an issue though: After 6-7s the diode starts blinking... So i wonder if it 's an overheating problem of the driver or my...

    Question about this driver

    So the Turbo mode works with the delay between the switch clicks? I don't mind if i ll have to just double press!

    Question about this driver

    @nmbusa this driver is the only one that had this kind of output current, in normal diameter, I think... So if i want to make this driver go for the max current what should i do to achieve this?

    Question about this driver

    @Shmackitup how exactly can i avoid all the lower settings and go straight to the max 5A? It s the first time i m using drivers with multiple modes... I m using a host with a tailcap switch only.

    Question about this driver

    Hey guys, i just received 3 of these drivers. http://kaidomain.com/P4000-20mm-5A-1-or-2-cell-3V-9V-6-Mode-Buck-Driver-Circuit-Board?search=P4000 I want to use them with NUBM44 but i want to make them work only in the max current... Is it possible to happen?

    Laser driver and low current switch

    Hey guys, i m curious if there are drivers out there, high current, that have a built-in mosfet circuit to allow the usage of low current switches. I have enough quality drivers sitting on my self and waiting to be used but all of them need good switches too. On my first 4.7w build i used an...

    Non anodised tailcap switches to buy

    Hmm actually i didn't think that it would be so easy... Thanks @Shmackitup

    Non anodised tailcap switches to buy

    I m preparing a couple of new hosts the upcoming days and at first i thought that i would also make custom tailcap switches. I didn't try yet but i think that buying the switches is easier. My problem is that I can't find non anodised ones... Any idea where to look for them?

    How many Amps should a NUBM44 draw?

    Finally after changing wiring on the diode amps drawing is correct... 5amps and even more on 5+V... And getting pretty hot 😎.... Now i have to build my new host and throw it inside!

    How many Amps should a NUBM44 draw?

    So if i wanted to measure directly from my psu what should i change? Maybe the length and the alligator wire gauge? Is it possible that the wire is too long and too thin?

    How many Amps should a NUBM44 draw?

    Hey guys, in the photo i m uploading is the amps that this diode draw from my power supply... I thought that the NUBM44 should draw about 4.5 amps at 5.2V if i m not wrong.... Am i doing something wrong by measuring the current this way or maybe this diode is not NUBM44?

    1st nubm44 build of 7

    @nmbusa if any spares nubm44 left dm me to buy one for my next build! 😎
