How to Use a wire wrap tool instead of soldering
This video offers instructions on how to use a wire wrap (or wirewrap) tool, an excellent and underrated alternative to soldering. It's particularly useful when prototyping as wirewraps can be undone quickly using the short end of the tool (though this particular process isn't demonstrated in the video). See how to connect a 4-legged RGB LED to header pins, a job that is particularly obnoxious to accomplish using solder and an iron, using 30-gauge wire and the tool. For more information, and to get started using a wirewrap tool yourself, take a look.
