The project is a 4-digit LED voltmeter and frequency counter that was previously based on PIC16C71 but was replaced by 28-pin device PIC16F876. The PIC16F876 is capable of driving 4-digit LED in ...

Flow sensors are useful tools for collecting data on the rate of liquid usage, but they need a device to display the data they collect. This three digit frequency meter was designed by [Turbokeu] to ...

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 ...

Many power ICs use frequency jitter, which spreads a control signal's spectrum, to control EMI (electromagnetic interference). If you need to add frequency jitter to power ICs that control three-phase ...

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 ...
