I didn't post in years but I found this and you guys need to see it

A few months ago I got a 520nm laser diode and a 12mm module, it worked perfectly with my psu, but now I want to put it in a host. I'm a student and my budget is quite small, like 20-30$ for the host (I have to order the driver parts and the pcb yet and is going to be expensive) Throught the...

Hi everyone again! Today I have read a quite interesting post in Hackaday about how to create a one button interface with a capacitor and a ic. The first think which I have thought is diy laser driver. The main problem of create a one button smart switch is that switch power off all the driver...

Hi everyone! I'm here for show you my new build, is a lpc-826 powered by a 10440 lipo with a amc7135 driver, all hosted in a tiny hugsby xp-1 flashlight host, set at 350ma have a nominal power of 230, here a few photos! (sorry for the size of the pictures)

A month ago I bought a lpc-826 (from e-Bay), rated for 200-300mw. That was perfect, I drived it with a lm317 and worked fine (386ma). I runned without a heatskin, but with 12mm module for about 5 seconds. The module got warm, the negative pin was unsoldered and got led. I think that 5 seconds...
