Has anyone ever seen a laser with light coming out from key lock. What the hell is this technology? Picture is captured from a *well know* company wxxxxxxxx.

So I try to parallel two BenBoost (900mA each) to get total 1800mA for my M140. However by looking at the schematic if I do this the two ben boost is actually have their senses resistor paralleled. In this case the resistance should be cut by half. Just wonder why two drivers will not affect...

Seem that I can't access into their website since yesterday. It keep giving me a connection time out error. It is the problem on their web site or just my browser crashed :thinking: ?

So I got three pointers from lazerer.com on earlier of april. One is 500mW 405nm cyber and another two mini red pointers 638nm 150mW and 650nm 200mW. I decided to review for two red pointer frist. I will review the 500mW cyber later when I have tme. 638nm one is LPM'ed at 148mW while the 650nm...

Hey guys, So I built a test load using 6 x IN5822 and a 1ohn resistor. It give a pretty accurate result for my 445nm diode. However it seem to give a much higher reading for the 405nm diode. Isn't that 445nm and 405nm diode are using the same test load? Any help would be greatly appreciated...

Hey guys so I finish my first 445nm driver base on tps611650 When I hook up the 445 diode to the driver nothing happen so I measure the Vout of the driver. I got the 3.9v reading while my battery is 4.0v (WTF? the driver is bucking?) So I hook the 650 diode to the driver instead and it seem to...
