What inspired you to do this?
I create a lot of electronic instruments and need ways of playing them. They aren't traditional instruments mapped to a melody, so standard piano key based MIDI controllers are overkill and also visually uninteresting. I wanted a different way of triggering contexts instead of just notes.
How long did it take to make it?
How long have you been doing things like this?
4 years for this recent period of tech work, but multiple decades as an artist.
How much did this cost to do?
$100 at first, using surplus A/V equipment. Another $100 in miniaturization and finishing later.
Have you done other things like this?
I haven't built any other computer vision systems, but I have made a sequencer from a bicycle wheel.
What did you wish you knew before you started this?
I wish I knew how important flushing the serial bus actually was for constant signals.
Are there plans available to make this? Do you sell this?
No plans for this one. It uses too much obsolete hardware. I doubt people will want to deal with all the issues that come with processing analog video.
Maybe a tracker for a dancer.
