50 MHz Frequency Counter
This project is nice and small frequency counter that reads
frequency from 1 Hz to 50 MHz that I have modified from original designed by Weeder Technologies . I have designed new PCB to fit with 16X1 LCD and change source code for compatible with new small PCB
Specifications
- Auto-ranging with floating decimal point.
- Up to 7 digits displayed on 1X16 LCD.
- Auto-adjusting gate speed (0.1 sec to 1 sec).
- Microcontroller-based circuitry provides for simplicity, ease of assembly, and highly stable readout.
- Sensitivity approximately 100 mV RMS (100 Hz to 2 MHz), 800 mV RMS @ 50 MHz.
- Input overload protected.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
