There’s something about clocks — sooner or later, every hacker wants to build one. And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

The supply of Nixie tubes from east European stock piles is still enough to keep their prices down. But once those start dwindling, prices will move north. Besides, if you want to use them, you need ...

A common display found on digital watches and readouts that looks like a series of 8s. Each digit is formed by selective illumination of from one to seven separately addressable segments. For more ...

Many options exist to drive seven-segment LED displays, but most are limited to low output currents. The approach described here uses one 74ALS374 or 74AS374 octal latch, wired as a shift register, ...

The project is an intro to Diode Matrix ROM where a signal is basically taken in and a number output on the display is given. The project is an intro to Diode Matrix ROM where a signal is basically ...
