Hi. :yh: Recent 635nm 300mW diode has interesting features. 1. Vf is under 3V. 2. Case-neutral So I can build this one with case-positive or case-negative. In other word, I can use positive-regulator(microflex, rkcstr, groove2...), or negative regulator(amc7135..). Amc7135 is a...

Hi.:yh: No laser driver around has "modes" as far as I know. I'd like to build my laser with modes. I have tested several LED drivers for 445nm LD from cheap sites as DealExtreme, KaiDomain. And I found a proper 445nm LD driver for one Li-ion...

Hi. I built a few of 445nm with v5, microboost. But maximum current of v5 to 445nm is 1.2A and microboost is 1.1A. So I am looking for high current driver. I have my custom P60 heatsink already, so I can use round circuit board for LED...

Ultrafire protected 18650 exploded.... I saw this at: Ultrafire 18650 3000mA exploded - CandlePowerForums In these days, especially after the appearance of high power laser, the usage of bigger battery, rapid exhaustion and mismatch of battery because of host design, is usual. I think laser...

Hi. I have some questions for dummy load: Can I use dummy load at about 1A of current? Is there dummy load for high current? When I set the current of driver (V5, microboost) and the current was near 800mA, the serial diodes(1N4001?) of dummy load became very hot and my multimeter showed the...

Hi. I'd like to buy some 9mm 980+ nm IR LD ranging 1 to 2W. I used to buy some from Heruurscieces, but now I heard he had a health problem. Thanks.. SHIN

Hi. All:yh: I was once a flashaholic and addicted in laser beam now. So I have collected and made a lot of flashlight. I started making my laser DIY and mod, these days. One day I'd like to make P60 style drop-in laser module. P60 is a well known flashlight module and its size is...

Hi, all. Harvest of red diode is not easy for me everytime. Today I've harvested red diodes successfully from Samsung SH-S223B and SH-222A. I was happy BUT when I tried to put it in Aixiz, it was strange..:yabbem: and I found that it was somewhat small. Oh my...:( The diameter of LPC-815 is...

Hi. everyone. I am a newbie and I planned to make my 22x dvd burner red laser. I want to make it in pen host. I have a question; Is it possible that a "rkcstr" drive of 420mA is powered by 2x 10440 ? I know a 10440(from AW) is 310-320mA of current. Can I make my red laser of 420mA with two...
