I tried firing up my 445nm 5w blue laser today and it didn’t turn on. The first issue I noticed was that there was no voltage going to the driver. I had to re-solder the joint that connects the negative copper ring to the threads of the laser body. It turns out the circuit couldn’t ground itself...

The build cost around $200. Huge shoutout to @Lifetime17 for the host and assistance throughout the build. Of course the first thing I got were some laser goggles from survival lasers. This is using the NUBM06 diode powered by a 4A buck driver so it should be around 5W. I used some thermal...

I’m building a 5W handheld laser and the only power supplys I have found that will work with the diode require a 12 V input. First of all, would it be practical to use a 18650 battery (would the battery life be short) and if so where can I find a 5W power supply that will work with 3.7 V...
