The device is a simple, small, and cheap frequency meter with out any hard to find components to be able to measure frequencies up to 40 MHz while having below 1% errors. Most of the analog and ...

The project was developed for measuring frequencies from 5Hz to 500kHz as it was based on the AT89C52 microcontroller. This 500kHz frequency meter is suitable for tracing and debugging most of 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 ...
