Metric Time=(60x(H-1)+M)/144.
The display runs on 12 volts and the toolstick runs on 5 volts and I don't know what i'll use for a power supply for it yet.. The toolstick is really nice because they cost about ten bucks and the programming adapter is about $7. I have the f330 model but I would suggest getting one with an external crystal since the one in the f330 has an accuracy of 2 percent, so I'll have to add a crystal myself.
I would like to be able to mount the clock on a wall, but right now the VFD is about 2 inches thick. The display and the electronics are on two separate boards and connect together with 10 pins. I'm going to de-solder them all and put the controller board below the display so it's thinner and the electronics are visible.
