Wire Wrap Items — The most reasonably priced wire wrapping tool is available from Radio shack. It wraps, unwraps and contains a wire stripper inside the tool. Its Radio Shack part number is 276-1570. Another good part to pick up there is the 10-segment LED display, part number 276-081. (An 8-segment display would have been more desirable, but it is not readily available.) While you are there you can also pick up some standoffs for the box which will hold the wire wrap project. Radio Shack part # 276-195 is a set of 4 that will do the trick.

Another item that you might want to get is a power supply. Jameco offers a variety, at times for less than $10. You have to consult their catalog because the offers vary as each stock is exhausted. Pool your orders to reduce shipping costs.
