The circuit has been designed for a person who loves to jog or walk while measuring the distance that have been covered during the activity. 4093 – a quad 2-input NAND with Schmitt trigger inputs ...

Max. Range: 9,950 meters with two digits slip it in pants’ pocket For walking and jogging This circuit measures the distance covered during a walk. Hardware is located in a small box slipped in pants’ ...

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit ...

Ah, the humble Commodore 1530 Datasette drive. It never enjoyed much popularity in the USA, but it was the standard for quite some time in Europe. [DerSchatten13] still uses and loves his 1530. When a ...

Implementing standard UART communication required use of Silego’s GreenPAK analog and digital blocks, with the end result being a Geiger counter that offers real-time radiation measurement. The Geiger ...

The challenge in measuring low frequencies is that the counter gate time is often too short for the signal relatively long period. This non-critical circuit automatically multiplies an input single ...
