PIC Controlled Clock Made From Old HDD

The HDD clock is built around a PIC16F628 microcontroller capable of reading IR sensor and lighting LEDs at right hard drive platter position.

There are 12 high power LEDs being used by the clock for displaying clock hands. The Minutes are represented by blue LED, Hours by red LED, and Seconds by purple LED. The operation of the clock is controlled by the custom programmed PIC16F628 microcontroller. The Hours, Minutes, and Seconds are set by 3 micro switches. In the lower drive platter, the drilled index hole and infrared sensor can be found. A clock hand is presented when the LEDs illuminate a slot produced by cutting a slot into the upper drive platter along with white tape on the center drive platter.

During the construction, an old hard drive is used which can spin in the presence of power. There would be 3 platters in the unit. The top one will have a slot cut into it, the second one will have a piece of white tape, and the third one will have an index hole drilled into it. A standard computer power supply is used as the power source.
