Linear Clock - More DIY How To Projects]]> /files/deriv/FBC/7QDW/GIJG0UA4/FBC7QDWGIJG0UA4.SQUARE2.jpg /files/deriv/FBC/7QDW/GIJG0UA4/FBC7QDWGIJG0UA4.SQUARE.jpg /files/deriv/FBC/7QDW/GIJG0UA4/FBC7QDWGIJG0UA4.SMALL.jpg ETN8909GGK2AREY Euphy Round clocks are so 20th century! Here's something a bit more post modern and obtuse. I'll be showing you here another full design project, from idea to design to prototype. The object of our desire today is a linear clock, that is, one that has numerals arranged in a line rather than in...

This reprogramming can be done with light and shadow, e.g. you could use your flashlight.This is...

The prototype has a CD4040 as counter and a CD4060 as the timebase generator. Gating the signal is by a resistor - diode gate. CMOS ics used here allow the instrument to be powered by any voltage in the range of 5 to 15 volts, but the maximum frequency is limited ...
