videosynthΩhm_2 proto Arduino Due video synth / audio visualizer (photos and video)

top view

The first prototype of the videosynthΩhm_2 is finished!
The videosynthΩhm_2 is a sort of video synthesizer or better a pattern generator that reacts to incoming audio. It is designed with live performance in mind.

The video output is lowfi, 8 bit style, glitchy and a little weird ;-)

This is my first bigger project with the Arduino Due. The Arduino Due is a nice board with more power as the standard Arduino. I'm using the Due VGA library by stimmer for generating a composite video signal. The library has basic graphics functions for points, lines, triangles, circles and rectangles and supports color output.

  • Arduino Due running VGA DUE library with custom sketch
  • Seven band graphic equalizer IC MSGEQ7
  • Audio in for an amplified electret microphone
  • 7 potentiometers
  • 4 push buttons
  • 1 RGB LED
  • Video out RCA
  • The first left potentiometer is used as program selector. The videosynthΩhm_2 has 8 different effects. The color of the RGB LED changes accordantly to the chosen program.
  • The other 6 potentiometers control different parameters (size, position on x axis, position on y axis, scrolling up and down, scrolling left and right, color etc)
  • If a pot is turned all the way to the right the values of the parameter changes randomly 

  • First button on the left: 
    • click: clear screen
    • hold: deactivate audio reaction on all 6 parameters
  • Other buttons:
    • click: activates the audio reaction on the parameter 1,2,3
    • hold: activates the audio reaction on the parameter 4,5,6

This are the specs planned for the next version:
  • real pcb
  • double stackable shield layout. One shield as VGA DUE library shield the other as controller shield
  • VGA and video RCA output
  • PAL and NTSC switchable
  • 6 LED + 1 RGB LED
  • 7 push buttons
  • new case design
and later perhaps:
  • LCD display
  • multidirectional buttons

  1. / Could you give me a more step by step guide to build one. I'm so into this. Love you're site BTW. :)

  2. In the next month I'lll work on the final release and then I'll share schematics and code.
    In the meanwhile look at:

  3. Alll cool. Thanks for those links!

  4. One of the coolest projects I have seen this year... AWESOME!.. hope the code and schematics will be released soon as open source.. great work!

  5. and, was that released?

  6. Fantastic! Where are you on this project? I would love to buy a kit from you. Are these available? Thanks

  7. are these available for purchase yet?
    thanks in advance!

  8. Seriously cool. If you put together a kit, I bet you could sell a bunch of these. I know I want to buy one!

  9. Would be very nice if these were for purchase as a kit

  10. Any chance, the code and schematics are available?

  11. sorry guys but this project will remain a prototype ... I'm working on other projects now

  12. Great project!
    Will you ever publish code and schematics?
    Please do it :-)


  13. As far as the uses of the audio mixers are concerned, the devices are used in a number of fields today. Starting from the broadcasting, television, sound reinforcement systems, public address systems, recording studios, and film post-production, the devices are used in a variety of settings.

  14. Be that as it may, it is smarter to get a full handle of the fundamentals first. This is the thing that most modules on varying media innovation for novices are about. American Audio Visual

  15. However, it is better to get a full grasp of the basics first. This is what most modules on American Audio Visual technology for beginners are all about.

  16. You won't consider audio visual gear support since it is the obligation of the rental specialist organization. conference av
