PIC16F84A 3.5GHz LCD Frequency Counter

This Auto Ranging PIC16F84A Frequency counter counts up to 35-40Mhz and has two separate input BNC connectors. A pre-scale chip from Nec/CEL may be added with Divide by 256 counters to achieve 3.5GHZ frequency measurements.

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]
