This clock creation is made of only a circuit board, a small motor and LED’s.

How it Works?

A motor spins the “propeller”, and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely.

If you want to build this clock, you will need a few things, including:

• Skill with motors and mechanical things.
• Prior electronic experience.
• A dead VCR or floppy drive or other source of a suitable motor and miscellaneous parts.
• A programmer that will program a PIC16C84 or 16F84 microprocessor.
