Parallel Port I/O Card with 24-Bit Feature

The 24-bit I/O card project has been designed to function with parallel/printer port of an Amiga or computer using the Intel 82C55 I/O chip.

Electronic Drum Machine Using Arduino

The project is using DIP switches to control he drum beats from the drum machine which is created by an Arduino system.

Flux Gate Magnetometer Based on FGM-3h Sensor

The project shows how the FGM-3h sensor is made to create a high resolution flux gate magnetometer that is used to measure variations in the earth’s magnetic field.

Micro Converter Based Pulse Oximeter

The project utilizes ADuC7024 to produce a pulse oximeter that is a medical device used to measure the amount of oxygen in a patient’s blood.

Development Board for PIC16F877/16F874

The circuit of development board was designed to support and test PIC microcontrollers such as 16F877 and 16F874 to interface with one of many programmers allowing the microcontrollers not to be removed from the board.

Simple JDM PIC Programmer

The project was named as JDM Programmer used for burning small PIC’s and as a serial programmer, it works on the serial port RS232 of a PC.
