README
README.mdLuminescent
A 60W handheld portal gun based on industrial surplus I acquired off eBay. I use a very high power laser diode array that is from industrial laser modules for purposes like copper treatment. It has a fully custom board that manages constant current regulation and battery management. It fits inside a 3D printable portal gun with a voltmeter, safety, and trigger.
Laser Safety
** Make sure to ALWAYS buy laser goggles from a reputable brand and with properly rated specifications. **
** Lasers are extremely dangerous and you should never look at them directly and always wear proper safety goggles. **
** I am not responsible for any damage caused from irresponsibly using lasers. **
General Tips for Working with Lasers:
-
The glasses that come with lasers are NOT safe, and will not protect your eyes.
-
Lasers over 5mW require proper laser goggles, 5mW is still dangerous however the blink reflex protects you in most cases.
-
Cutting with lasers releases fumes which need to be filtered or ventilated to a window, preferably both.
-
An enclosure is the BARE minimum for safety along with properly rated laser goggles.
-
Do LOTS of research before working with lasers. Diode lasers need to be treated very carefully especially.

Questions
How big is the Laser Rifle PCB?
It measures 88.5 × 86 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Laser Rifle use?
68 parts, built around the ESP32-C3-WROOM-02-H4, USBLC6-2SC6, XT60-M. and IRLZ44NSTRLPBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Laser Rifle KiCad files?
From the Firestorm108/Luminescent repository on GitHub, at the commit this page was made from: the board is KiCad Files/Laser Rifle.kicad_pcb and its schematic KiCad Files/Laser Rifle.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Laser Rifle design in my own project?
Its repository states no licence, so its author keeps all rights: ask Firestorm108 before reusing the design.
