Excellent video on replacing the old jeco clock motor with a programmable step motor. I  really like the idea of adding an wwvb  receiver

aka atomic clock to the jeco.

 

Thats pretty slick.  if you haven't had the chance to play with one those arduino boards will do darn near anything you want them to.  Its based on a programmable EPROM type chip so once its programmed you dont need the computer any longer.  When this guy is done he could program the set buttons to forward and reverse the time plus the 4 wires to run the clock and hide the arduino somewhere in the dash hooked up to clean power, it would probably run forever.  You could add a wireless controller too to set the clock via wifi every time it gets back to the house.  Anyway the options are limitless

Very slick.  But, being a child of the last century and not a programmer, I prefer using the $3.95 guts from a Sharp Quartz Analog battery powered clock from WalMart as the Z clock upgrade of choice.

I ran across a post over on hybridz where a guy is trying to run his old original datsun gauges off the can/bus of his megasquirt 3 using arduino.
