Have a few of these meters, but probably not enough for a clock. I do need to come up with a creative office clock though.

@DIDEFIXIT: Think retrograde Very cool idea meters they count up and snap back. The sound needs to be like a water clock

Oooh -- I like both of these ideas!!!!

@Zeeglen, rick, two good and easy solutions.  I shouldn't make statements like that before I have had my coffee :-)

@Rcurl I don't think it will be difficult at all to drive a zero-center meter from a single power supply, though.

An H-pad would do the job, would take 2 bits to drive it.

Hmmmmm....is a Vetinari clock one that only animals can read?

I was soooo disappointed to have missed the Hamfest this year- although it sounds like you made off with all of the choice stuff before I could have gotten there anyway.

Next year I wonder if they would let me in if I ride an electric scooter with a small trailer behind!

@David:  I was going to suggest a centre-zero meter (I might even have one for you if you want) but really if you're going to drive them with an MCU then you can make them do what you want anyway, and centre zero meters need + and - drive voltages which would make life difficult.

I was thinking the same thing.  I don't think it will be difficult at all to drive a zero-center meter from a single power supply, though.  Just put a big electrolytic capacitor in series with the meter movement.

To go along with it, maybe synthesize a "tick" when it flicks left and a "tock" when it flicks right.

Tick..Tock Sound

@Max: This is an interesting idea:

Personally I'd go with keeping it simple and make it so the dials are easy to read but make the dial look aged.

The sound selection for the tick..tock would depend on the responsiveness of the selected meter. A slow response might work better with the sound of a larger clock while a faster response might work better with that of a smaller clock or watch.

@David: ...270 degree meters [...] any of those in your stash?

I think there are a couple, but the ones I'm using for Mins and Secs are a semi-matched pair (same manufacturer and same look and feel - -just one was originally intended for volt sand one for current -- but I'll be replacing the legends on the faceplates anyway).

The ones I have have a 90 degree movement -- and that will be OK for 6 major marks with 10 smaller ones between them.

LATEST ARCHIVED BROADCAST

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
