Hello everyone, this is my first full DIY 445 build and I am pretty proud of it.
Modeled after a Walther PPK I dissected and modified this airsoft pistol into a high powered 445nm laser.
It took me a while to dremel the metal frame to accept the parts and modifications that I wanted to make but all the hard work payed off in the end.
My diode is being driven buy a well heat sinked 1.8A jib77 driver and providing the voltage are two AW 17500 batteries. Finding batteries that fit inside of the host but still had enough juice to last a decent amount of time was an adventure in itself. The two batteries are held in place by slightly modified AA battery holders. I decided to utilize two different switches, a traditional slide switch and momentary on / off switch. The slide switch acts as a safety similar to a firearm. The laser only functions when this switch is in the "on" position. And of course the momentary switch is activated by pulling the trigger.
A big thanks to Jayrob for creating the perfectly fitting heat sink:thanks:
Battery holder modified with an earth magnet
1.8A jib77 driver heat sinked with pennies
Momentary "trigger" swith
Survival Laser focus knob
Bottom few threads ground down two focus the G-1 lens
This is my favorite laser so far and I plan on making at least another laser with an airsoft gun host because I think they make pretty sweet lasers.:eg:
Thanks for reading,
