This is a project I did for the Make:NYC Labs. We don't have a power supply for everyone to test their completed projects, so I took 20 minutes and about $6 in parts and made a snake.

This snake uses 8 alligator clips, 2 banana plugs, and a reasonable length of CAT-5 cable.

Fully Insulated Mini 1-1/4" Alligator Clips (10-Pack) - $3.49
Flexible Banana plugs (2-Pack) - $2.79

What? You don't keep a stash of shrink tube around? Bah. Use tape.



First we strip out about 4 inches of wire and separate the striped and solid ones to create positive and negative busses. We attach the appropriate banana plug to each group.



Then we strip away about 1/3 of the wire covering from the other side of the cable. Shrink tube the junction where the covering ends to prevent fraying. We shrink tube each pair of wires together to keep them from coming apart then attach alligator clips to their respective wires.

Quick and cheap. Just how I like 'em.
