Don’t watch [Jason Hotchkiss]’s video if flashing lights or bleepy-bloopy synthesizer noises give you seizures. Do watch, however, if you’re interested in a big honeycomb-shaped LED matrix being driven at audio frequencies through a dedicated square-wave synthesizer that’s built in.
The LED panel in question is housed in a snazzy laser-cut, honeycomb-shaped bezel: a nice change from the standard square in our opinion. The lights are 1/2 watt (whoa!) whites, and the rows and columns are driven by transistor drivers that are in turn controlled by shift registers. We’re not entirely sure how the matrix is driven — we’d love to see a circuit diagram — but it looks like it’s some kind of strange, non-scanning mode where all of the column and row drives are on at once. Whatever, it’s art.
And it’s driven by logic chips making audio-frequency square waves. Two of these are fed into an LFSR and into an R-2R DAC and then into the shift registers. The output is chaos, but the audio and the visuals do seem to influence each other. It’s an audio-visual embodiment of some of my wildest Logic Noise fantasies. Pretty cool. Enjoy the video.

The circuit diagram is in the article: http://hotchk155.blogspot.de/2017/02/meet-wobatron.html
Woops – here’s the specific image: https://4.bp.blogspot.com/-mwh9uM6ffp4/WLQjjRkK4MI/AAAAAAACvKY/adZK969qNmM-WcRr2orUh8xJ5uGvjOOgwCLcB/s1600/matrix.png
Sounds like something from Forbidden Planet. And it looks like something from Forbidden Planet too…
Cool! I like my seizures with flashy lights and bleepy synth noises. That hexagon matrix is really nice.
That was my first thought xD. Second thought was use for shady human experimentation.
Hello Professor Falken. How about a nice game of chess?
Do you want bees?
Because that’s how you get bees.
mount that shit to a flying contraption and you got ur aliens!
… cept they’r 70’s horror-scifi aliens
Very cool…love everything about this!
