Mystic Circuits: PFRsillator Mini - Fundraiser for Protester Bail Fund
Mystic Circuits
"I'm using some DIY kits that I had from a previous fundraiser to raise money for the Minneapolis and Los Angeles Freedom Funds as well as for Afrorack. If you would like to donate to these organizations directly the links are:
https://www.gofundme.com/f/peoples-ci...
https://minnesotafreedomfund.org/
https://www.afrorack.org/
If you would like to buy the kit, go to our website: www.MysticCircuits.com"
"A simple DIY kit designed with DIY beginners in mind. The full kit comes with everything you need to build a PFRsillator Mini along with a power supply (wall supply in the states, 9V battery for international purchases). There is a complementary build video to show how to build this kit in real time, showing each step in detail without fast forwarding through anything. The synth itself is a touch-based noise maker which is very responsive to small differences in pressure. You want modem sounds? This thing makes a wide variety of them.
This kit is intended to fundraise money for the ongoing BLM protests happening now, of every order $20 will go to the Minneapolis Freedom Fund, $20 to the Los Angeles Freedom Fund and $5 to Afrorack. If you would like to donate directly to any of these organizations please check their respective links [above]"

via noystoise where you'll find the full post with additional build pics.
"Got a friendly message from none other than Mike Walters of Mystery Circuits. He had been tasked with repairing an odd-looking synth that resembled something I would make. Sure enough, it was the heavily modified Yamaha PSS-30 I had built on commission some 8 years ago."

Mystery Circuits' Grateful Dead Emulator II Restoration
Published on May 6, 2019 mysterycircuits
Above are a couple of demos of an Emu Emulator II restored by Mystery Circuits. Is it the same one you see pictured left with Brent Mydland of The Grateful Dead? You can find a post covering some of the history and restoration of this Emulator II on Mystery Circuit's website here.
Update: I asked Mystery Circuits what the serial number was and he said it's hand written and faded, but appears to be SN 983.

Radio Ace - Mystery Circuits AMFM Drum Machine
Published on Aug 24, 2015 mysterycircuits
"Radio Ace is a programmable drum machine built by Mike Walters that uses an AM/FM radio for the source of the snare drum noise. There's an analog bass drum, and it gates an input in time with the beat. Snare (radio), and Input have individual adjustable sustain. Tempo control can go up to audio frequencies. Press the SNOOZE bar to turn off/on the rhythms! Built for Mark Lewis, 2015 www.mysterycircuits.com"

Circuit Shaman Eurorack Expanders for the Music Thing Turing Machine
Bytes Expander
Update: looks like the above link is dead. The original link went to www.circuitshaman.com, which now goes to www.mysticcircuits.com.
"The Bytes loop length expander allows your Music Thing Turing Machine to create random loops and melodies in any musical time signature. Breaking free from the constraints of 8 and 16 steps, with the addition of the Bytes Expander your Turing Machine will be able to create loops of any length from 1 to 16 and alter that length with a control voltage. Say goodbye to Kraftwerk and hello to Coltrane.
With the use of two separate length controls it makes it easy to change the Turing Machine's time signature in a musically useful way. For example, set the lower control to '6' and the upper control to '12' and you can easily double-time your loop. The CV-selector switch and attenuverter allow for some control to tame incoming CV, setting the selector switch to either side makes it so that CV only affects one of the length controls, allowing for one length to be your "solo" mode and the other to be your "repetitive" mode.
The Bytes expander attaches to your Turing Machine through the "gates" expander port and via 2 jumper wires that connect to the original Turing Machine PCB. As such, the Turing Machine PCB requires a small amount of modification to be able to work with the Bytes Expander. What is for sale is both the expander itself and the service of upgrading your Turing Machine. Send me your unit and I will do all the hard work for you."
Bytes Turing Machine Loop Length expander explained
Published on Nov 25, 2014 Circuit Shaman
"Here I go through the basics of the Bytes expander and give a couple of examples of how I use it."
Below is the Music Thing Rainbow Turing Machine build from Circuit Shaman with Bytes next to it.
"The Rainbow Turing Machine (Originally by Tom Whitwell of Music thing) is a random voltage loop generator for Eurorack modular synthesizers. It is useful for creating melodies and modulation with a variable amount of randomness. This particular module comes with all of the available Turing Machine expanders and uses different colored LEDs in every way possible. The colored LEDs serve a practical purpose as well as an aesthetic one since the color of each bit is coordinated to the main display across all of the expanders."
Published on Apr 24, 2014 wind spirit
"Did you say that there isn't enough color in your modular? Well this modules uses just about every color of LED available (that would be safe for your eye.)"
Switches Expander
"SWITCHES is an expander that turns your Turing Machine into a sequential switch. Its set of 8 switches are summed together to 4 different outputs. Two switching methods are used: the top four "clean" switches use a high-precision switching chip and the bottom four "dirty" switches use vactrols for some extra character. Bi-directional switching is possible through use of an upcoming multi-purpose expander."
via Music Thing Modular
And finally the Vert expander.
"VERT is an 8-bit digital to analog converter with an internal clock, allowing a CV signal to be converted to 8 gates. Unipolar or bipolar input signals can be selected by a switch to cover the entire range of conversion. The internal oscillator has a range switch to select between audio and LFO range as well as an attenuator for the FM input. An expansion port on the back allows the Vert to connect to any Turing Machine expander, allowing new functionality to be added in the future. The onboard LEDs come in 8-color rainbow or a single color of your choosing. A trim pot accessible from the front panel allows the LEDs to be dimmed to the preferred level of brightness."
Note this is the first Circuit Shaman post.

Trommemaskine - Mystery Circuits Drum Machine
YouTube Uploaded by mysterycircuits on Feb 12, 2012
"Trommemaskine built by Mike Walters, 2012. 8 x 4 matrix drum machine uses modified Paia Drum-Tone circuit for sounds. More info at mysterycircuits.com"

"This is the Trommemaskine, commissioned for Olivia Hjermitslev. "Trommemaskine" means "Drum Machine" in Danish. Rhythms are mapped out on the 8x4 matrix panel, which includes a Hi-hat, Kick, Snare, and a Disco drum.
Those four sounds, as well as four additional percussion sounds, can also be triggered by the blue momentary switches. A toggle switch sets whether the drum triggers once, or at the rate of the sequencer.
The large orange button starts and stops the rhythm."

New Tapes for Drumssette
YouTube via mysterycircuits | July 18, 2010
follow-up to this post.
"Thanks for all the positive response for The Drumssette! I've had some requests to show more tape examples, other than just the 808 sounds I had before. Here you go! The first segment shows sounds I recorded with my Minimoog. The second shows CR78 sounds, the third are acoustic sounds. I'm hoping to get sounds of my drummer, Kuki, real soon."
