Welcome to Cathode Corner.

New Square Nixie Watch

I am pleased to announce that my new square Nixie watch is available! I have redesigned it to be more sleek and thin. It comes in colors. It's USB rechargeable and water-resistant.

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.

Scope Clock status update

OK, so the new Scope Clock board isn't quite ready yet.
I was not happy with the quality of the new circle generator circuit.
I've got some ideas for improving it, and I do have plenty of CRTs to make clocks with.
Here is some information on the 2008 board.

A super deluxe round Scope Clock is in the works

I have been working for years on a truly beautiful scope clock package
worthy of sitting on the mantel of the finest home.
