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’ ...

I took a Computer Logic Design class in college, so when I stumbled upon the Ksimus Circuit Simulator, I was intrigued. At the risk of waxing nostalgic, I remember what it was like to build circuits ...

Straight out of the golden age of DIY electronics, the Digital Wooing Aid circuit turns TTL logic into tender words. It’s ...

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 ...

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 ...
