I'd want the kit.

Nice idea. Perfect for when I need an excuse for being late. "My alarm clock's window comparator had too much hysteresis" or similar analog mumble-jumble. Oops, that won't work. He stuck in some digital (Atmel ATtiny44). There went the analog purist market.

What's a "twitchy needle" display mode?

Reminds me of the no digit digital clock. just a ring of leds like a regular clock face.

I think it was in PE, or Radio Electronics.

Cheers

I think I can guess(tm) how it works. The Atmel chip is a digital clock, with two outputs of hours and minutes in either BCD or Binary format. The two outputs go to two DAC's which drive the meters. Very clever methinks.

I've been saving ancient analog panel meters for no reason that I can recall. I'm tempted to build such a clock and put the meters go good use. Analog meter scale drawing software:

Probably buggy firmware, turning a bug into a feature.
