Analog Clock turned DC Voltmeter


The concept is easy. Use the "time" on an analog clock to display measured voltage values between 0-12VDC. 1 o'clock means 1VDC, 2 o'clock means 2VDC; if the time reads 10:30 that means 10.5VDC, etc. To do this a stepper motor is connected to the adjustment knob of the analog clock. See:
