Yet another meter clock

It seems that meter clocks gained some popularity among hobbyists. Probably because it’s a bit challenging and great looking projects. This one is based on AT89C5051 microcontroller. Circuit is pretty simple where timing is counted by DS1307 chip and analog meters are controlled by sending voltage levels through DAC converters and amp buffers.

Clock is graded to 24 hour scale and can show hours, minutes and seconds on three meters. To see more packaging examples follow here.
