4: If your wires are very short, (less than 9 inches) you may additionally favor to lengthen them via soldering wire to them. Be careful not to add to tons as it may additionally not in shape in the Altoids tin. About 9 inches (22.9 cm) branching off of the woman USB have to suffice.

The units used are milli-Amp hours (mAh), which can be explained as the contemporary (in milli-Amps) wished to thoroughly discharge the battery in an hour. A one thousand mAh battery will be remaining twice as long on one cost as a 500 mAh battery. AAA battery holders can cheaply be bought from Radio Shack, make positive it will healthy in the Altoids tin–this generally capability to purchase the thinner square looking one–see an image in Things You’ll Need.)

Strip the wire exposing the colored wires. You may also reduce the white and green wires. Strip the purple and black wires. Connect the wires collectively (red to purple and black to black) via soldering or wire twisting (unreliable.) Cover the character wire connections together with electrical tape, having 2 separate portions (cover the black to black one by one and crimson to crimson separately.) Then after the reds and the blacks are one after the other included in tape, you can cowl these connections with electrical tape so you are left with a single wire.
