ROTFL ..... it just remembered me one of my first DIY ..... it was, like, 8 years and half ago, when 5mW pointers still had inside a decent module with a real diode (and not a bare chip on a piece of brass like now
) ..... took it away, modded to 11mW (yes, they had trimmers and current control circuits
), then put it in a little old broken pneumatic piston (as body), made a head with the brass part of a valve, and put the module with the beam coming out from the center of a 6 x 5mm led diodes ring, 4 high power white and 2 UV ones, keeping it keychain size ..... it worked for 4 years, but then, at 11mW, the diode stopped to work, so i throwed it somewhere ..... don't remember where it is, now, but if for any luck i find it, i post a pic just for the fun.
But, keep in mind, it was 8 years and half ago, when these "combined" pointers was not available ..... to be precise, it was just starting to appear on the market keychains with a red 1mW laser and a 3mm white led, at exagerated prices ..... you can't imagine the fun seeing the faces of the sellers, the first time i gone in one of these electronic fairs (or whatever you call them
) ..... stopping at their desks looking these pointers, and when they ask me if i was interested, replying "no, thanks, as you can see, i already have a keychain that do it better, and also have UV" and showing them it ..... you can't imagine the faces of some of them, LOL !
