Audio synthesizers can vary from huge racks of apparatus with modules stitched collectively by an internet of patch cords to a few 555s wired collectively in an Atari punk association. This light-controlled synth is available in nearer to the decrease excessive of that vary, however packs a sonic punch that belies its simplicity.
The challenge is the most recent model of [lonesoulsurfer]’s “Moog Mild Synthesizer,” which shares plenty of the circuitry present in his first version a few years in the past. This one has plenty of bells and whistles, however it all begins with a PWM oscillator that contributes to the imply, growling high quality of its sound. There’s additionally a low-pass filter that’s managed by a few light-dependent resistors, which could be performed by blocking them off with a fingertip. A few inverters type a drone oscillator that may be switched into the circuit, in addition to a 555-based arpeggiator to cut issues up a bit.
All these circuits, in addition to assist for a thirteen-key keyboard, stay on one customized PCB. There’s additionally an off-the-shelf echo/reverb module that’s been considerably hacked so as to add to the richness of the sound. The customized wooden and acrylic case make the entire thing look pretty much as good because it sounds.
We famous that [lonesoulsurfer]’s earlier “Box of Beezz” drone synth appeared to evoke components of the “THX Deep Word” at occasions; equally, a few of the sounds of this synth sound like they’d come from the soundtrack of a [Christopher Nolan] movie — test it out within the video beneath.
