A circuit made for displaying the time using 7 segment display (for decimal display) and LEDs (for binary display). I used an Atmega16 microcontroller and shift registers in the schematic. For more details contact me.

Oscar Gonzalez from BricoGeek has build a nice clock using 7 segment displays and LED matrix. The clock uses and Arduino MEGA with a Real time clock module and an SHT15 board from SFE. Six digits 10 cm tall shows the current hour and date. 4 LED display matrix are used to show temperature, humidity and an RSS feed from the Internet. [via]

Nick Hall builds a LED Pong clock, project files and source code is included. [via]
This project uses the classic video game Pong to tell the time. The 2 players automatically win and lose so their scores reflect the hours and minutes. The clock can also show the time written in words, or with large or small digits. Two buttons allow you to set the time and change the clock mode via a menu screen. The project uses 2 LED matrix panels from Sure Electronics, an Arduino, and a DS1307 clock chip.

This project shows how to build a GPS based clock. This clock is able to display accurate time received from a cheap GPS module. The clock is based on PIC18F1320 and uses MAX6951 LED display drivers.

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.
