The CK-1000K Clock Kit is for INDOOR USE ONLY

A solid segment LED display version of this clock is also available fully assembled.


We also offer a small display LED Digital Clock Kit

The CK-1000K has a legacy going back to 1995. It was the first large display LED clock kit that we offered for sale. We adverstised it in Nuts & Volts Magazine, and sold quite a few of them to get us started! After re-designing the clock display for solid segment LEDs, we started receiving emails and were amazed to see how many people enjoyed and actually missed the "dot" style display! It certainly looks "unusually attractive and eye-catching." So we are keeping this original version of the CK-1000 alive as an electronic kit.
