DDS Signal Generator with USB Control

The USB controlled signal generator project was created to produce sine waves and other waveforms at audio frequencies using DDS.

WAV Player Using dsPIC Microcontroller

The project demonstrates an audio playback of WAV files with the use of dsPIC constructed on a breadboard layout with SD card access.

PC Serial Port IR Communication

The circuit is aimed to provide a method for receiving serial data on one pin and transmitting serial data on another with a modulation at the IR detectors band pass frequency.

Homemade PIC Programmer

The project was a modification of a JDM PIC programmer and has to be connected through the serial communication port of the computer without the use of any external power supply.

Universal Clock Generator Based on GPS

Building a universal clock generator would provide extremely accurate timing for GPS satellites and GPS Ground Segment in order for GPS users to be aware of their Earth position.

USB In-System-Programmer for AVR

The circuit of AVR In-System-Programmer (ISP) has been modified to function with USB connection to a PC.
