Anyone can build a fun and useful laser target pistol from an old Nintendo Zapper!
It's an easy project and the parts list is short:
* Nintendo Zapper
* laser diode
* 10-microfarad electrolytic capacitor
* 9v battery & battery clip
* various wires (pref. red & black)
* soldering kit
* hot melt glue gun
Have fun!

I'm a bit confused about the wiring
Battery pos > back (closed) switch post
Battery neg > ?
Cap pos > center switch post
Cap neg ? ?
Laser pos > front switch post
Laser Neg > ?
Did you combine the neg leads from the battery and laser and attach them to the neg cap lead?
Thanks

wait does this thing burn stuff like most of the laser gun .

no, but it is not "eye safe". this particular laser diode is only rated to 4 milliwatts (considered relatively safe), but this mod pumps it up to about 326 milliwatts for a short pulse - definitely NOT eye safe! please be careful with these things and don't shoot people or animals. :?)

Why do you put the laser on the side of the barrel why not mill out a cavity in the barrel
Reply 11 years ago on Introduction
there's already a huge cavity in the bore, and you certainly could do that. you'd want to put some sort of spacer in there so it fits snugly. i did it this way so alignment would be quick and easy. it actually works great! cheers. ~P

any chance of links to where you got your diodes etc?

it's been a while, but i think i remember getting them from All Electronics:
http://www.allelectronics.com/make-a-store/item/DLM-3/LASER-DIODE-MODULE-650NM-4MW-3VDC/1.html
that looks like them. :?) the caps and 9v battery clips should be really easy to find. i buy most of my components from Adafruit, SparkFun, Gravitech, etc. i hear you can get better prices on DigiKey if you know exactly what you're looking for and speak "engineer"...
cheers!
