Magnetic Rotary Encoder Project

The project is based around the AS5040 chip that uses a magnet to provide positional feedback information and 10 bits of resolution per rotation.

Outdoor System for Garden Monitoring

The project was intended for measuring the moisture content from the resistance between two probes to produce a garden monitoring outdoor system.

Analog Geiger Counter with Digital Output

The project is an analog Geiger counter that is capable of detecting and measuring the three forms of radiation including alpha, beta, and gamma radiation.

Mini Digital Voltmeter with 3-Digit Display

A PIC version of digital voltmeter module was created based on an AVR while showing the mini display with 3 digits.

PIC18F252 Based Logic Analyzer

Using the PIC18F252 or PIC18F2525 as capture device, the project was designed to build a low cost logic analyzer while showing the display on a Windows based PC.

Frequency Meter with 40 MHz Measurement

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.
