Build a digital clock with its digits levitating in the air using PIC16F84

Red digits on this photo appear to float in the air in front of the clock. This illusion is based on inertia of a human eye. If LED-formed digits will periodically and frequently enough flash, they will appear solid and steady. And since the matrix of digits is formed by a mechanically scanned single line

Gear Clock using PIC16F676 Microcontroller

I can’t take credit for the design of this one. I bought the gear as a clock a few years ago. It was mounted on a frame and had one of those cheap clock units running it. The gear is designed to be driven by the minute-hand shaft of the clock mechanism. The problem was

Propeller Clock Mechanically Scanned LED Clock using PIC16C84

This is the first clock I ever built. I’ve built a few LED signs, but they get boring because I already know the message. How this clock 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

2 Digit up/down Counter using PIC16F628A

This project comes via two circuits on 2 boards. The first circuit is designed around a PIC16F628A. It has been presented on an experimental PC board using surface-mount components and was built in less than 1 hour, with about 2 hours to write and finalise the program. See P1, P2 The second circuit uses a
