If you’ve ever tried connecting more than a few parts with normal jumper-type wires on the bottom of a solder-type proto board (basically a grid of holes), you know how ugly the wiring can get. This instructable shows how to use a home-made needle-in-pen dispensing tool to route enamel coated wire. Making a few wraps on each pin also saves you from using up nearby holes. Will all enamel just melt off when soldered, or would you have to sand off the end? Another question, how well does a normal wire-wrap tool work on regular length leads?
