    A Sociable Bicycle

    You could try an uneven build, so that the wheels aren't in the middle, but so that each rider has the same momentum (weight x distance).

    Quick Connect Circuits

    I was thinking of a wood-block circuit project for kids. I like the block idea because connecting blocks are not only cheaper than little bits they more intuitively show that you are building a "circuit"! I like your copper tape idea, it makes it feel electrical.. The magnets: I would get rid of the side magnets, make the blocks wider and add two magnets on each end, mounted with opposite polarity. (let's say, left is always N, right is S). This way, blocks can be turned around and always connect. (Important for diodes). Of course one wouldn't need to get rid of the side magnets, just make them pairs of two as well. But I think it would be cheaper to add branch pieces: 3-way T and 4-way X connectors for branching. If one adds straight circuit pieces (wire only), the branc...

If one adds straight circuit pieces (wire only), the branch pieces could simply be steel covered in copper tape, no magnets.

    Build Your Own CNC Machine.

    This probably would not work for woodworking. The tools in this setup (plotter. 3d-printer, laser) put very little stress on the mechanical setup (motor, belts, bearings, rails), so one can "get away" with reusing scanner parts.
