Nixie watches are back in production.

This is the old style round, black watch. You may have seen it on the wrist of a certain computer geek. Click here to buy a Nixie watch.

Bike Boom Box

I make a sound system for bicycles that I call the Bike Boom Box.
It provides 15 watts per channel of stereo sound from an MP3 player and bolts to your bike's rear rack.

Click the picture for details.

I also made a super-big bike stereo called The Loud Bike.

It makes 300 watts of danceable music power. Bring the party with you!

The Video Coat is my craziest creation

I figured, why not make a TV set that you can wear. A big TV set.
