John sent us his flickr set that shows you how to make these really nice Breadboard Power Connectors. Thanks John!

Inspired by a couple of posts on the Make magazine website, I made up a set of leads to connect my bench power supply to a solderless breadboard. I used a couple of old 8-pin wirewrap sockets, some wire recycled from a PC ATX power supply, and four 4mm plugs (to fit the bench PSU). I made four leads because my PSU has three outputs, plus ground.
