Video Overlay with ATmega8 Microcontroller

The project was designed to create a video overlay board that will allow the display of GPS data and call-sign on an NTSC video signal.

APRS Tracker Known as WhereAVR

The project is a low cost APRS tracker that is lightweight, low-power, and low-cost with a full complement of analog and digital I/O while having the ability to decode ax.25 packets.

USB Interfaced VGA Clock Device

The project utilizes a PIC chip to create a clock that will display the time in an old monitor and will behave like a USB device.

Temperature Controller Based on AVR

An AT90S2313 and a Dallas DS1621 Digital Thermometer to create a controller where the temperature is displayed on a dual 7-segment display while the parameters are set using the two buttons.

Programmable LED Based on PIC Microcontroller

An AVR chip is used to design a great programmable LED which provides fun and a good building block for playing with collective behaviors.

Spectrum Adapter Using PC-Keyboard

The adapter project provides the possibility of connecting to expansion bus like the joystick adapters, in order to connect a standard AT or PS/2 type of keyboard and work with the Spectrum.
