Video Overlay using ATmega8 microcontroller

A few years ago I set about trying to design a very cheap and simple way to superimpose flight data on live video being transmitted over amateur television. Specifically, the data would include things like Latitude, Longitute, and Altitude, among other text including an identifier like my callsign. Before I go on, I want to

Nikon Camera Remote Control using ATtiny13 Microcontroller

This is an IR remote control for Nikon cameras. It is compatible with the Nikon ML-L3 remote control. Supported cameras include: D40, D40X, D50, D60, D70, D70s, D80, Coolpix 8400 8800. This design is based on an idea from http://www.bigmike.it/ircontrol/. The circuit is extremely simple: an ATtiny13V, button, transistor, resistor, IR diode and 3V battery.

Arduino VGA via Interrupts using AVR Microcontroller

Arduino VGA via Interrupts using AVR Microcontroller

Part 1: Introduction For some people, interrupts are a mystical thing that they think they will never understand. To that I say non-sense! And to that effect and to help us also better understand VGA, let’s see if we can’t output some basic VGA signals like we’ve done before, but this time using some interrupts!

VGA Monitor adaptor using AVR microcontroller

VGA Monitor adaptor using AVR microcontroller

Background of the project. Several months ago I tried to connect a microcontroller system to a VGA monitor to output data in the form of text. I was surprised to find little on this subject on the internet, to assist me in achieving this goal. Certainly nothing simple a beginner could find useful. There are

Open source color video game development system based on AVR

This project describes an open source color game development platform based on an AVR microcontroller. You can code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on this system. All video processing is done by software in background using interrupts, with no external active components. You only need to
