The Countdown to Maker Faire Bay Area is On!


“Craft” 80’s computer audio & video

Computers & Mobile Technology

David sent in this cool AVR project called “Craft”. It uses an AVR microcontroller to make 80’s type computer graphics and music. If you just can’t wait to hear the awesome music, skip to 1:00 in the video. All the schematics and lots more pictures are on the web site.

Having successfully built a soundchip out of a microcontroller together with my friends in kryo, I wanted to tackle the greater challenge of generating a realtime video signal along with the sound. This is the result.

    Very impressed with both the software and the audio/visual show.

    I do all my AVR stuff using a basic compiler (bascom). It works great – but I suspect I’d run out of ROM shortly after getting the basic video + sound working.

    Nice work!

    Just like some of the better C64 demos. It’s pretty much all here:

    – Realtime, 4-track, “chip” style music
    – Pallete Cycle
    – Plasma
    – Fire *and* mirror effect
    – Starfield
    – 3d tunnel
    – rasterized “twist”
    – bouncy text
    – waveform visualizer
    – 3d point cube
    – animated fractal

    All that with no dedicated sound or video chips, although running at 20Mhz probably helps a lot. This is impressive to say the least.

    Maybe this will usher in a new kind of demo compo at Assembly?
