Frequency counter 400Hz to 50MHz with PIC 16F84
It consists only from Microchip PIC 16F84 cpu and LCD text module. Author states that this counter is capable metering frequencies from 400Hz to 50MHz. I used faster, 20MHz version of 16F84A-20I/P, and it managed to count 80MHz oscillator output....
Frequency Counter Circuit using Micro Controller

Inexpensive_frequency_counter_tachometer
This circuit illustrates the configuration of an ICM7217 and an ICM7555 designed as a basic frequency counter. The connections between the ICM7217 and a common-cathode LED display are depicted in Figure 12-18. Calibration of the frequency counter is accomplished using...
Crescendo ampilifier elektor1982
The Elector Crescendo was the first DIY amplifier that was not a kit. The design was sourced from the Elector magazines available at a local library.
The Elector Crescendo is an innovative audio amplifier designed for DIY enthusiasts. It features a...
Precision-frequency-counter-tachometer
In this configuration, the display shows hertz directly. When pin 11 of the ICM7027 A is connected to V00, the gating time is set to 0.1 seconds, allowing the display to represent tens of hertz as the least significant digit....
