John Burton decided to build a circuit that could display line and pixel drawing on a TV using a PIC, after some attempts his efforts paid back.
The first attempt (apart from the test phrase hello) was an analogue clock and now John is able to display also text.
Nice job and another cool application for this powerfull microcontroller.
Complete info on the steps of the project can be found here and here.
Hans Jørgen Grimstad is making a clock with some nixie tubes and a dekatron and houses it in a beautiful case. The result is really good and that "nostalgia" feeling surrounds it, inside though arduino and xbee modules keeping the clock running.
Details can be found here but not all in English.
Josepino made an clock with Almost No Parts (that's what ANP stands for). With only 10 parts this clock is standing to its title but doesnt compromise in features. Using a PIC microcontroller as the heart of the circuit this clock can use common cathode or common anode 7-segment LED displays, display time in both formats (12/24), disable the display as battery saving option, control the brightness and operate in a 2.5 to 5.5 volt range. What more can you ask for? Detailed schematics and options (works with 2 types of PIC) can be found here.
mrnick1234567 took 2 x Sure 2416 LED matrixes, an arduino and came up with a large 10x14 number font matrix clock. The displays are driven using code written by Westfw and for more info you can check here.
mb1988mb1988 build a very sleek propeller clock and put it in a neet casing, the results are awesome and looks very proffesional. You can also have different time displays or even graphics. Code and more details can be found here but you have to know Polish :).
Jason Amsel and Konstantin Klitenik made a clock from an old hard drive and also used an LCD touchscreen acting as display and controller for time setting. HDD clocks are not new but combined like this i think its the first time. In the page you can find complete documentation, schematics, scripts and video links showing the clock in action. Watching time never was more fun.
