LED clock with DCF77 time sync
This is what I call a project! No, it is not yet another POV LED clock, this one is quite simple. Well, not simple "simple" really, it actually syncronises itself with atomic clock located in Germany over long waves on 77.5 kHz by using DCF77 receiver.
Another very important thing about this project is using ISA NE2000 network adapter card with target microcontroller ATMEGA8515. With network support this device dan be used as NTP server. Now that is something! Source-code is available for download on author's webpage.
