1. Introduction
The Digital Clock Model CLK100 was designed to fill the need for an accurate digital clock with the

This clock has 6 digits for hours, minutes and seconds and the hours display can alternate between
two time zones, i.e. Coordinated Universal Time (UTC) and local time.
The CLK100 is offered in kit form or fully assembled and tested. The kit is easy to assemble with no
surface mount parts.

is fully open source for both the hardware and firmware. There are full schematics and pictorial
diagrams of the hardware, also there are links and flowcharts of the firmware microcontroller code.
