Peter Blasser has a very unique Web site where you can download and print paper “circuit boards.” These circuits are for building music-making projects--sans the more “conventional” copper-clad board substratum. Just print the circuit board, layout the components, and wire the traces. How about adding some conductive paint and starting a revolution in circuit building? Try this “wire glue” (The Electronic Goldmine #G16133; $3.95) for making your pPCB connections. This combination could be an interesting method for introducing kids to electronics without the need of purchasing a classroom’s worth of soldering irons. If you try pPCB + Wire Glue, please post your results in our comments section. —Dave Prochnow
