A classic LED digital clock circuit, implemented with straight logic - no microprocessor or multiplexing. Just like we made in the 1970's, when the availability of red LED's and TTL logic made this possible for the first time. The lack of multiplexing keeps down the radio-frequency noise, and also makes this a great driver board for a much bigger display, e.g. using photocoupler relays to drive fluorescent tubes. Great value, high quality kit. Includes sockets for the IC's, which are probably best skipped for long-term reliability, unless you are scared of damaging the chips.
