vidi-synth experiment 1
an early attempt to make an audio controlled video-image-synthesizer.
this experiment used 4 IC’s containing NAND gates, AND gates, hex-triggers, and a ripple counter thingie.
the counter borrows its clock from an external video synch pulse, also used to synch the display here.
it had lots of stability and a 1K pot could be used to drastically change what kind of patterns were coming out.
another circuit converts audio into voltage control for extra fun.
the horizontal red lines in these stills were reacting to audio amplitude:
will probably have to dismantle this piece by piece to figure out the simplest way of recreating the effects which i liked here.
sometimes it was working really well with the audio but, as i was trying out a lot of different connections, am still not entirely sure why.
some other stills:
video file:
this video file (10MB) is just an image sequence of the thing running but not at speed… should have made proper video documentation with sound of course, but didn’t.
[...] It appears as though a computer system is not entirely needed for creation of wonderful patterns on video displays. Brian of MediumRecords has built a prototype circuit with several gates and a counter IC to generate really neat sound responsive patterns on a monitor with BNC connectors for each component. These are very early stages however a video synth like device is planned in the near future. Nice work on the pattens and the video is very neato, reminds me quite a bit of Wobblevision but with more colors and patterns. [...]
