The project aims to build a simple and easily-reproducible RF/Microwave frequency counter that is based around a PIC16F876A microcontroller. This particular frequency counter has three inputs ...

B&K Precision has introduced a pair of 10 digit frequency counters reaching 3 or 6GHz, with ±1ppm stability across their +5 to +40°C operating range. “This series utilizes a reciprocal counting ...

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 ...

[CuriousMarc] is back with more vintage HP hardware repair. This time it’s the HP 5245L, a digital nixie-display frequency counter from 1963. This unit is old enough to be entirely made of discrete ...

May 13, 2013. Saelig is now offering the QPX1200SP 1.2-kW DC bench-top power supply featuring PowerFlex regulation, designed to meet the need for flexibility in the choice of voltage and current. The ...

You think of digital displays as modern, but the idea isn’t that new. We had clocks, for example, with wheels and flip digits for years. The Racal frequency counter that [Thomas Scherrer] is playing ...
