I knew that the wire leads to the laser were sensitive (from the comments), so I used lots of epoxy putty for strain relief. Maybe a bit too much putty.

It is hard to see from my crude photos, but there is a momentary contact switch on the side of the ring, activated with your thumb.

Needs to have a shark head on it…so you can have freekin’ sharks with freekin’ lasers on their foreheads…

Looks like you work with LEDs a lot! What are those round tins on the desk? They look great for projects.

The tins are Lee Valley watchmaker cases, the 48mm size

They only come in 12 packs, but at $7 a pack that’s not too bad.](Woodworking Hand & Power Tools & Accessories - Lee Valley Tools)

Alas, the laser card module has been retired.
