The Anita desktop clock
The Anita Clock is an unique single-digit desktop clock DIY kit which displays time in sequences, 10's hours, 1's hours, 10's mins and 1's mins and is made with single LED segments on a PCB which forms together a 7-segment display with 8 inch (20 cm) height. So far, clock kits for such big displays are not yet available on the market, especially as an optical highlight the display board looks "translucent" so the digit seems to be detached in the enviroment. So you'll get an unique piece of jewelery which also serves to "de-celerate" the everyday pace of life hectic as the time can not be read just with a glance.
But how can the clock display the time with only a single digit?
The clock displays the time in a sequence of four digits, each with a small pause between the individual numeral and a longer pause at the end of the sequence. It's really intuitive, and once you have understand the sequence, reading the time is very easy.
Mr.Nixie's "Power-Tank"
The Anita Clock is equipped with a new generation of 1 Farad super capacitors featuring an extremely low internal resistance of less than 1 ohm, making them ideal for smoothing or filtering current peaks; a so called "Power-Tank".
As the maximum current consumption of the display, when green and blue coloured segments are used and all segments are turned on, is up to 1 A, the use of such a capacitor type was intendend. The fact, that the numeral never remains continuously turned on, the capacitor is able to buffer the short-term (for a normal USB port) very high power requirements and thus ensure a more uniform load across the USB power source.
Actual time is 18:08 in the video.
