I recently discovered the new 520nm green laser diodes that don't require the frequency doubling stage that regular 532nm green lasers need, which means I could finally build one as small as I wanted. I gutted a Nitecore Tube and turned it into a 30mW rechargeable green laser pointer with some...
Here's a video of my latest laser project - it's a scratch-built 100mW green laser with a graphical display and instrumentation of current, voltage, and temperature. It has adjustable output power, a password lock for high power, and is usb-c rechargeable.
Here's my latest laser build:
445nm projector diode
Flexdrive @ 700mA
IMR 16340 Li-ion
DX 1x123A flashlight host
The thing that makes this pointer really special is that it is the first use of my Laser Lock system to increase the safety of the device. I have used a PIC 10F206 microcontroller...
I've been a lurker for a long time, and I've received a lot of great information from this forum, so here's an attempt to give back-- as far as I know, my focus dial idea hasn't been used elsewhere already, so it may be of use to some of you.
Here's my Dorcy Bluray build. It uses...
