Eventually I'd like to build a laser gun. Not high powered or anything. Just using a Nerf gun or something of the sort.

So a while back I threw together this build. It is a wiring mess on the inside.
It wasn't meant to look pretty, it was more of a proof of concept for me. Something to learn on. (The batteries part)

2x18650 batteries. Wired in series for the driver and parallel for balanced charging. Installed charging ports as well.

Once I tear this back apart and build it into another host, I will add a safety key switch.

Part of me thinks I should leave it alone since I do have another one of these diodes in the drawer.

Cool. The more you build the easier it gets.

Nice one TK.
I've been planning to build a laser gun for ages too.
Gives me inspiration now.
Thanks
