Check out Dave’s excellent prototyping box built from a child’s lap desk.

I frequently work on projects in the living room in front of the TV while sitting on the couch soldering away hunched over a disarray of wires, parts, wires, speakers, cords, breadboards, and tools. Whenever I want to work from the couch I have to go into the studio and make 15 trips up and down the stairs, cables, toolbox, parts boxes, soldering iron, etc. It’s always a major hassle. Then, when I’ve finally completed mocking something up on the breadboard and I want to test it I need speakers, headphones, a sound source and I have to connect it all with alligator clips. It’s really inefficient and makes me less apt to start a project because all I can think about is the huge mess it’s going to make.

Dave’s project write-up includes a great description of the build process as well as wiring diagrams. Awesome!
