@Tloose: Use a solenoid to strike the inside of the wooden box to make an authentic sound...

That's not a bad idea -- but I also want to have other sounds, like on the hour the sound of (rusty) clockwork graunching and straining and then letting loose with a release sound as the hour meter flips over to the next hour...

@Hamster: You could almost sell these :-)

Unfortunately, I only ever make one of anything, then I get attracted to the next "shiny thing" LOL

PS Did you see the email I sent you?

@Hamster: Maybe make the seconds tick inconsistently, but have it bang-on when the seconds hand goes from full scale back to zero.

Sometimes it's almost like you are reading my mind -- in fact I'm planning on writing a follow-up column about possible operating modes and associated sound effects.

@Hamster: Max, this is going to be an awesome project - one where I think everybody will get the juxtaposition of old and new tech.

Well, of course it's an awesome project -- you suggested it LOL

@Clarke: ...Do you have the voltage and current specs for each?  I imagine they'll require more power than a microcontroller output could provide...

That's one of the problems in that you usually can't find any documentation for the meters. Also you often end up modifying them by removing shunt or series resistors. Also you have to be careful measuring the internal resistance -- in some cases you can "blow up" the meter using (trying to use) a multimeter to determine the resistance.

In some cases like a meter that's geared to to measuring say 10mA max, you could drive this directly from the MCU output -- but you also have to remember that the meter itself can generate negative voltages due to reverse/back EMF. Personally, I prefer to use the MCU output to drive a transistorm and have the transistor drive the meter -- all of this will be covered in my forthcoming blog.

@Clarke: ...I'm curious how you're planning to drive these meters...

I'll be using the MCU's PWM outputs -- Ill be writing a blog about this in the next week or two (as soon as I get some time LOL)

@larussell: How about doing the whole thing analog?

Do I look like the sort of man who would soil his hands with analog when digital is so much more "shiny" and "tasty"?

Max, this is going to be an awesome project - one where I think everybody will get the juxtaposition of old and new tech.

I still think that making it "dead on" accurate using a GPS time source would be pretty cool - "I'll just sync my pocket watch with atomic clocks orbiting the earth, using my steam-punk analogue meter clock".

Maybe make the seconds tick inconsistently, but have it bang-on when the seconds hand goes from full scale back to zero.

Neat project!  I've lived more in the digital realm than the analog, so I'm curious how you're planning to drive these meters.  Do you have the voltage and current specs for each?  I imagine they'll require more power than a microcontroller output could provide so I'll have to stay tuned for the next report to learn how you plan to do that.
