This project shows how to modify an old hard drive to make a LED clock based on PIC16F628 microcontroller to control clock operation. The clock is using 12 high power LEDs to display the clock hands. There is also a slot cut into upper drive platter and white tape on center drive platter provides a slot that when illuminated by the LEDs will represent a clock hand. Three micro switches set hours, minutes and seconds.

This project is a meter clock that is styled like a VU meter. The two meters are attached to servo motors and are controlled by a PIC 18F2550. The box is build by y first making a form, then laminating thin sheets of wood. Complete project documentation can be found on the link below. [via]

spritesmods.com built a clock display using thermochromic paint. This is a kind of paint that changes color when heated. He used this paint to paint some resistors and placed them in seven segment arrangement. When proper resistors are heated they form the digital numbers and the time is shown. The resistors are mounted on protoboard. When the resistors are dissipating around 500mW the corresponding segment is changing his color to light grey. When they are shut off they gradually fade to dark grey in 60 second.

This project is a Nixie Clock using 4 tubes and common components. This clock is designed to be easy-to-build and it’s build using two boards one over the other. Clock works at voltages from 7.5V to about 14V and consumes around 200mA. The shield board has 4 RGB LEDs under the Nixies that can be turned off if you don’t like how it looks. It shows time, full date and temperature.

This project is a clock able to display time on the CRT tube of an oscilloscope. It uses a PIC16F84A and four resistors configured to work like a 2bit R-2R DAC. Bruno Gavand used both timing and Y axis controls to display the numeric values on the scope screen. It also has two push buttons, one for hours and one for minutes configuration. [via]

This project is a Real time clock shield for Arduino based on DS1307 realtime (RTC) integrated circuit. It is a fairly accurate clock that can keep time when not powered if you add a 3V battery. Data is transfered to microcontroller through I²C  bidirectional interface. It is connected to Arduino at pins 4 and 5. Check schematic on the link below.
