We’ll normally have a tender place for circuit sculpture jobs anything at all with elements supported on nice tidy rows of brass wires usually captures our creativeness. But include to that a small bit of mild and a great deal of seem, and you get something like this hybrid synthesizer sculpture that really commands awareness.
[Eirik Brandal] calls his development “corwin level,” and describes it as “a generative dual voice analog synthesizer.” It’s developed with a large-open architecture that invites exploration and serves to pull the eyes — and ears — into the piece. The lowest amount of the sculpture has all the “boring” digital stuff — an ESP32, the LED drivers, and the electronic-to-analog converters. The up coming stage up has the additional visually attention-grabbing analog circuits, designed primarily “dead-bug” design on a framework of brass wires. The consumer interface, mostly a collection of pots and switches, lives on this amount, as does a SeeedStudio WIO terminal, which is employed to show a spectrum analyzer of the appears produced.
Shifting up a little bit, there’s a seemingly incongruous vacuum tube overdrive along with a power amp and speaker in an acrylic enclosure. A vertical element of thick acrylic towers more than all and residences the synth’s hold off line, and the light pipes that snake via the sculpture pulse in time with sequencer events. The online video under exhibits the synth in action — the music that it generates by no means actually sounds the same twice, and sounds like nothing at all we’ve read prior to, apart from potentially briefly when we heard some thing like the qualifications audio from Logan’s Run.
Hats off to [Eirik] for one more good-on the lookout and terrific-sounding create you may perhaps recall that his “cwymriad” caught our consideration earlier this year.
