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 <br>Battery pos &gt; back (closed) switch post <br>Battery neg &gt; ? <br> <br>Cap pos &gt; center switch post <br>Cap neg ? ? <br> <br>Laser pos &gt; front switch post <br>Laser Neg &gt; ? <br> <br>Did you combine the neg leads from the battery and laser and attach them to the neg cap lead? <br> <br>Thanks
<p>crap, how did i not see / respond to this post from THREE FRIGGIN YEARS AGO?!</p><p>all the negatives are tied together. it's called a &quot;ground&quot;. hope this helps the next guy.</p>
wait does this thing burn stuff like most of the laser gun .
no, but it is not &quot;eye safe&quot;. 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. :?)
alright
Why do you put the laser on the side of the barrel why not mill out a cavity in the barrel
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:<br><br>http://www.allelectronics.com/make-a-store/item/DLM-3/LASER-DIODE-MODULE-650NM-4MW-3VDC/1.html<br><br>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 &quot;engineer&quot;...<br><br>cheers!<br>~ Peter
you rock XD thankyouuuu
