AVT2879 B

We present an unusual electronic clock that shows the current time on the vertical lines of the LEDs. However, this is not its only function. The device is also used for flashing, lighting and ... nice looking. This was achieved by adding additional shining diodes. So that the whole did not give the impression of a chaotic composition, a compact surface assembly was used. The system is interesting because only traditional digital integrated circuits of the 74 series were used to build it - there are no microprocessors in it.

The device is especially recommended to all electronic engineers who want to recall the 'digital' series 74 and build an unusual clock

Selected parameters:

• presenting the current time on vertical bars with LED diodes
• setting the clock - microswitche
• push switch signaling - LED diodes
• chip built in SMD technology
• the possibility of using LED diodes in various colors
• layout based on 74 series digital circuits
• power supply - 4 - 6Vdc
• tile dimensions 87x64mm
• in the set a printed circuit board, a set of elements and documentation
