Digital clock projects have been with us since the 1970s, when affordable LEDs and integrated circuits became available. In 2026 most of them use a microcontroller, but for the AliExpress fans there’s ...

There are two types of clocks and they tell the time in different ways. Analogue clocks have a face with numbers from 1 to 12 and two hands. The hands move and point to the numbers to show what time ...

An analogue clock, a clock with hands, shows the numbers 1 through to 12. It is a 12-hour clock. The first 12 hours of the day, from midnight to midday, are called am. The next 12 hours, from midday ...

Abstract: Power domain nonorthogonal multiple access (PD-NOMA) is an effective technique to improve spectral efficiency. When the power allocation strategy changes, the power of the signals ...

Abstract: With countless applications, time measurements are among industrial electronics' current most important challenges. This is not a matter of precision, which by now standard architectures ...

I got a bit tired from soldering SMD components, writing firmware, (and also observing people building vintage-looking Nixie clocks using modern microcontrollers). And recently when cleaning my parts ...
