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
