Half Life 2 Portal Gun
Basically, I wired all of my LED's in parallel with my 33 Ohm resistor in series to my batteries. I wanted to have a 3mm LED on the tip of each claw of the emitter, one for the center of the emitter (shining backwards into the vacuum chamber), one more for the vacuum chamber, and two for the sides of the reactor. That's 7 LED's. I also wanted a rocker switch at the handle on the side. The batteries needed to be accessible as well, so I put them on the inside of the lid to my left cylinder.
Also, it's important that each LED in your circuit has it's own resistor. The only reason I wired my resistors in series to my parallel LED circuitry was because I simply didn't know any better.
First, I bored a small hole for my switch leads to go through the bottom of my left cylinder. Then, I cut a square out of the side of a plastic lid and was able to fit the rocker switch in it and hot glue it in place as well as against the outside of my left cylinder. The resisters were twisted up in parallel and soldered them between my switch and my battery holder. That's it for power and control. Now for the LED's.......
After soldering wires to all of them and heat shrinking the tubing on my connections, I tack glued the three LED's on the emitter on the inner part of each claw facing the center. The leads went down the claw, turned 180 degrees, and went back through the hole next to each claw. The positive and negative leads were soldered together and were connected to a common positive and negative lead going to the middle of the gun.
The common leads that went from the front of the gun to the back were hidden. I fed the wire through a cardboard strut on the outside of the glowing vacuum chamber. This was intended to keep wires from being visible in the middle part of the gun. The strut was glued over a small hole that the lead went through into the reactor part of the weapon. Two LED's on the sides of the reactor met up with the common leads here. Then, my common leads exited the reactor and went into the lid of the left cylinder. There, they connected to my batteries, switch, and resistors.
Half Life 2 Gun Mod
Jul 28, 2014 - Portal 2 mod Aperture Tag replaces the portal gun with a device that. Originally began as a free mod built in Half-Life 2's Source engine. Oct 18, 2007 - I'm trying this out as I make this post. Here's the guide.
