Voltmeter gauge transformed into a clock
I felt like we needed another geeky clock in here, so here is one made out of a an analog voltmeter gauge.
It is actually disguised as a voltmeter gauge, not made out of one. Voltmeter-like scale is printed on a paper and placed on a wooden box. The inside of a box consists of minimal part count and the main component is the servo actuator which is controlled by a PIC18F1320 microcontroller. The PIC micro is also used for time keeping with its internal Timer1 which is configured to interrupt on every 25ms at 8MHz clock or 10ms at 20MHz clock. The code and the schematics are on the project website, so you can build this stealthy looking clock.
