This is definitely one of my favorite projects and it is hanging in my living room. It is an "analog" clock built up with LED's. It also shows the current date in the red circles in the center. The face is made of aluminium. I made all the holes by hand. I drew the circles with a compass. It has a receiver for the DCF77 time stamp signal so it will always show the correct time. As this is also an older project it does not have etched PCB's. The clock is powered by an AVR AT90S4414. I also made the case myself by bending a metal sheet. I then coated it on the outside with felt so that it wouldn't stain the wall. The wired matrix for the 72 LED's.
