The Single Digit Clock Kit. We love this idea, a single digit clock that displays the time as a sequence of numbers. One at a time. OK, so you’ve got to have the patience to stare at the face for a few seconds to get the whole time info, but it’s a small price to pay for such family fun and confusion isn’t it? $21.95.
Now THIS is the ultimate gadget digital clock for the electronic enthusiast! It’s just one single digit… but at least its big! A huge bright red 57mm 7-segment display displays complete 12-hour time format in a sequence of digits… one digit at a time! The display is mounted in the hi-tech attractive dark enclosure that features a single button to control all features. Also includes a “blank display” dark mode. Built-in clock accuracy is 30ppm
