Whilst working on the lighting for my case today I decided to post a quick guide on making your own LED case illumination. Its a very quick, in-expensive and easy alternative to using cathode tubes which I think people may find useful as this lighting method can be placed almost anywhere in the case. -Shopping List- 2 x 5mm 3.5v LEDs (I will be using super-bright blue) 2 x Suitable Resistors - 12 Volt or 5 Volt 2 x lengths of Wire (I am using solid core bell wire, black & Blue) 1 x Housing box - Maplins code JX56L is a good one to use 20cm heatshrink - Here 2 x 5mm LED holders - (I am using Maplins code N89AX as needed black) 1 metre of aquarium air hose (or cable braiding or your choice) -Tools- Wire Cutters Needle Nose Pliers Corded/less Drill - 3mm, 8mm & 9mm Bits Ruler Pen Masking Tape Ok thats everything you will need to make 1 lighting unit housing 2 x LEDs. This would be enough to illuminate a third of an average size case to the brighness of a cathode tube. 1st Step - Mask the box you have chosen as the housing, measure and mark where each LED will sit. Drill a 3mm pilot hole then enlarge to 9mm. Repeat this on the rear of the housing but enlarge to 8mm. Remove masking tape 2nd Step - Take the LEDs, heatshrink, resistors and LED holders Join the resistor to the longest wire on the LED and apply heatshrink, repeat with second LED and Resistor. Now join one wire to the resistor and another wire to the shortest wire on the LED, again apply heatshrink. I used back and blue so its easy to see which wire is positive (blue) and which is negitive (black). 3rd Step - Now moving back to the LED housing, insert LED holders into the 9mm holes (if using different holders check mounting hole size) Once inserted tighten the small nut to hold them securly in place. 4th Step - Next twist the 2 wires together for neatness. As I am using solid core wire this is very easy and the wires stay together and keep thier shape very well. 5th Step - With the LED holders in place and the wires twistes together, insert the LEDs through the rear 8mm hole on the housing and into the holders. Most LED holders will come with a small plastic plug to hold the LED inside the holder. I did not use this as I prefer to use a very small amount of superglue around the rim of the LED.
