Hello, I would like to ask if anybody is using laser module from odicforce in combination with nubm44 diode. The diode holder seems to have hole for diode pins with too small diameter. Is it possible to use this module host with nubm44 host? Or do I need to drill that hole to make it wider?

Hello everybody, I'm planning to build nubm44 handheld laser. I found somewhere that it can output 7,9W @ 5.5amps but Im wondering what host should I use. Using survivallaser c6 or s4 host with so small heatsink would be very bad idea. Looking forward for your replies.

Hello, After making the guide of making cheap red laser build for about 33$ Ive decide to make another one, but much much cheaper. Part list: 10pcs Red Laser Diodes ML101U29-25 - 29.98$/10=2.998$ each 10pcs Laser modules 5.6mm with acrylic lens - 19.99$/10=1.99$ each 5pcs 9V battery clip -...

Hello everybody, I need to know atleast model number, or max current it can eat. I don't believe the description on ebay. Ive found same description for more diodes. The datasheet would be good. High Burning Power 0 9 Watt 900mW 808nm Infrared to 5 9mm Laser Diode Gift | eBay

Hello everybody, I used this schema to make drivers to run red diodes, but now I would like to make ddl driver to run IR diode, so I need about 2,2V @.5-1A, what changes should I do to this schema? I will use 3,7V 16340 battery. 3,7V - 1,5V(lm317) = 2,2V so voltage is good but the current...

Hello, Im planning to build new lasers 405nm and 808nm. I will buy these diodes 250mW 405 410nm CW 5 6mm Blue Violet Blu Ray High Power Laser Diode | eBay 808nm 500mW 5 6mm to 18 Infrared IR Laser Diode No PD | eBay but don't know what drivers should I buy. Any suggestions? thanks for your help :)

Hello everyone! After long waiting Ive received all things I needed to build that red laser. I would build a cheap red laser. Here is the list of all parts. Survival Laser DIY C6 Host Assembly 10.89$+1$(drilled driver pill) Survival Laser Red Anodized Aluminum Heat Sink 7.99$ 10pcs Aixiz...

Hello, Ive got this driver Adjustable Current Laser Diode Driver 80 500mA w TTL | eBay Im confused how can I make it work. Id like to use 2x cr123a or 1x 18650 battery, I have a C6 host with battery contact board in it but dont know how to connect the driver to the battery. Those diodes can...

Hello, just simple question, what voltage should 3V rcr123a battery have when fully charged? Im charging it with my nitecore d4 and it shows 3,4V and still charging... is it normal? EDIT: The battery is probably broken... got 2 of same kind and only one of 5 bar was blinking and the charger was...

Hello everyone, can anyone suggest me some cheap red diode module with output about 300mw+? + any cheap driver... this gonna be my first red laser

Hello, I have a question about this diode driver. I have the one from 1.6A to 2.3A. I need to set it to its minimum 1.6A... Ive heard somewhere that if I set it completely Counter Clockwise its 2.3A and completely Clockwise its 1.6A. Is it true?

What do I need to solder it correctly and without shocking the diode? Would ESD gloves absorb the static electricity? Or do I need anything more?

I wonder what do you mean by killing the diode. No light at all? I have 1,5A at tailcap and the beam is weak. Could it be the discharged batteries even with 1,5A at tailcap? When its focused it has a circle around the dot of the beam. Amperage on the tailcap with 1x 16340(3V) and 1x 18650, dont...

Hello, I need help with my DIY test load.. Im going to use this schematic That Ive found in some another topic... I just dont know what diodes and resitor do I need to make it... I need to set the current at 1.8A for my m140 diode with SL-SD-3 driver.

Hello, Ive bought a Xtar 18650 battery 2600mAh and a cheap charger. Battery works well but when I try to charge it the led indicator starts blinking red. Any ideas what should be wrong?

Hello Ive just finished my first m140 build and I have a little problem. I cant see the beam at all... It looks so weak. I used S4 host, m140 diode and adjustable (1.6 - 2.3A) SL-SD-3 driver from survival lasers. Im not able to adjust the amperage to the exact value so I just set it to the...
