Elektor Quasi-Analog Clockwork Kit

  • BrandElektor Labs

Description

The Elektor Quasi-Analog Clockwork Kit (Dimensions: 160 x 245 mm) is a digital clock with an analog look and feel.

The clock consists of 144 3-mm LEDs in a circle, indicating 12 hours with a 5-minute resolution. 11 standard logic ICs are used. All components in the kit are through hole.

The circuit uses standard HC-logic and still one 4000-logic IC (CD4060), a 32.768 kHz quarts reference clock and a 5 V power supply. Any small 5 VDC adapter (not included) can be connected via a small screw-terminal block on the board.

The quasi-analogue clockwork uses 144 LEDs (light emitting diodes) to indicate the time on a round, quasi-analogue dial with a diameter of about 143 mm. One of twelve green LEDs lights at maximum intensity to mark the hours, while the other eleven are dimmed. Between two green LEDs sit 11 red LEDs, each of which represents a period of five minutes. In this way, the time is indicated with an accuracy of five minutes. This would seem to be enough in view of the mostly decorative function of the present clockwork.

Construction of the clock is fairly easy as all components are through hole. A detailed description of how to build the Quasi-Analog Clockwork can be found in the manual of this kit. It can be downloaded here. Please read the manual before heating up the soldering iron!
