UPDATE: For a crucial safety update and time saver head to Step 6
Step 1: The Shopping List
>>1 USB wire, doesn't matter what kind as long as at least one end is standard USB A (look below)
>>1 3-5v LED
>>A sweets tin, in this case a small box from some garbage shaped sweets.
>> OPTIONAL: If your box or case has any plastic that is dark in colopur it will absorb the light more, if you cover this plastic on the inside of your box or case ((in this case at the top of the box there is a bit of dark plastic on the lid)) with a layer of tin foil, shiny side facing the light source, then your box will be better lit.
Also to ease the job along you should consider:
>>A standard pair of wire clippers
>>A handheld drill
Step 2: Electricals
1. First snip of one end of the cable, make sure you leave the end that connects into the computer; on.
2. Then (carefully using your wire cutters) strip the black outer covering of your wire, you want to take about, 3cm of black covering off
3. Then you should find 6 wires, one braded one that wraps all round the cable, another silver one that is with the braded one. Then behind a silver paper film, 4 other wires, Black Red Green and White.
4. Remove everything leaving only the red and black ones
Step 3: After That Lot...
Step 4: Now to Get Down to Business
Step 5: Now to Really Get Down to Business
1. Make sure the circuit isn't gunna short itself, keep the linkages clean, and organised
2. Make sure the current flows the right way round, LED stnd for Light emtting Diode, on a diode the power can only flow one way so you must get it right, try one way, test it buy plugging it in, to your PC or PS2, and if it doesn't work turn the led round, rewrap and retest. The LED will have 2 legs coming out of it, one should be shorter than the other. Connecting the shorter one to the Black cable, is the general rule of thumb.
Step 6: Bam!!!
Now for the update: To save time and prevent issues such as the LED legs burning or the components being damged, and to reduce heat, please consider installing a resistor in the circuit, if like me you are using a standard 3v LED u need an 1/8 watt resistor coded --- Brown Grey Brown --- Now for the end of the update... There we go!
