A thorough and nice no input mixing tutorial by Sarah Belle Reid (2019).
Build a perf-board unit of the a Simple EQ / Baxandall EQ module (the Tilt channel is still in the making). The build was an ordeal. I did how ever learn that the reverse polarity protection of the circuit works well (it even saved an IC I popped in the wrong way) and that my noisy DC 5-24v to Dual Power 12v -12v 5v -5v 3.3v supply is robust. I attempted to plan the build using various board design tools (Fritzing worked best for me) but ended up just soldering components down following the schematic.
I added two switches to my build, which can be used to bypass the capacitors controlling the bass response (27nf) and/or the treble (1nf). Changing the 27pf didn’t have much effect. I added female pin headers which can be used to insert different capacitors in their place. My first water capacitor (using faux s.pellegrino) shows a value of ~35pf and it has an effect on the sound. Next I’ll build more water capacitors, which hopefully will have higher values for more distinct effects. I’ll also have to design a front panel, which can used to mount the bulky capacitors (The one I have has ~20ml of water in it).
During my tests I’ve discovered that the electrical resistance of sparkling mineral water drops slowly (as the water loses its bubbles). I believe that this property could be used as vca of sorts. I plant to make a simple signal divider, which uses sparkling mineral water as a conductor. This signal multiplier would be useful for one-shot slowly amplifying ramps (for example adding volume). Water and electronics is a beautiful combination.
Secured a set of rails to my rack to accommodate 1u tiles. Breadboard a Simple EQ / Baxandall EQ unit. Everything works but I’d like to boost the volume. The diy water-capacitor is in the making, the epoxies and insulators are taking a long time to dry. Used acrylic-paint as an insulator, got the idea from Johann Diedricks Sound Monsters workshop. Kids painted over the boards with thick paint after soldering them and the units worked fine after (the paint needs to dry).

Made a shoulder pad for my hoodie using the front of my Frenchie’s Gym cap. Looks cool. The cap was always to small for my head and it works better as a fashion joke anyway. Took a one and a half month break from gym activities due to a shoulder injury. I have a gym date on the 17th and I have just enough time to restore my gains.
Wrote a summer text for Mustekala.info Puu kaatuu metsässä – Tunnelmia Kiilan äänipäiviltä Kemiönsaarelta [Tree Falling in the Woods – Vibes from the Kiila International Sound-Days at Kemiönsaari]. An easygoing review which includes a short history of the event and an overview of all of the works presented this year. Includes some fancy casually post-humanistic sentences: “[their piece] explored constructions, which enable the production of sound in bodies, animals and other wind instruments” (concerning a performance by Ragnhild May and Kristoffer Raasted). Also summarized Yan Jun‘s from last year performance which I wrote shortly about. Got to interview Tolvi, Juho Laitinen (got a micro-lecture on art!) and Teemu Lehmusruusu for the text too.
Jesse introduced me to the concept of post-ore (jälki-malmi). He came up with the concept after spotting scum with aluminum and copper traces in the lot of an old foundry. Its a very useful concept for Ore.e Refineries. Post-Timber works too (see this crafty palindrome as a performance). We build a sauna (using post-timbre) with him in two days. Needs insulation but gives a good löyly.
Breadboarded a Microphonie (Music Thing Modular) and made a unit on perfboard too. Turns out my DC 5-24v to Dual Power 12v -12v 5v -5v 3.3v is incredibly noisy. Works ok, not as loud as I hoped and a bit noisy (most likely because of my building skills). Using a battery works cleaner. Tested it with my μZEUS too and begun to build a (water)capacitor (will be dry tomorrow).
Added an array of capacitors to my Electroslush. 4u7 does not do much, 10u has a more audible effect. Changing the caps next to inductors has as a stronger effect. My plan is to build a capacitor myself (using mineral water as the conductor or electrolyte and plastic as the dielectric), use this cap as a filter on an audio amplifier circuit which will amplify the sound of the Electroslush (which will be listening to filter capacitor I build). This should make for an oscillator, which sound character is determined by the electromagnetic field of the diy mineral water capacitor.
I might use Tom Whitwells SimpleEQ (with exposed sockets for the capacitors next to the the bass and treble pots) and Mikrophonie as basis for the design. Electroslush -> Mikrophonie (or two for stereo) -> SimpleEQ (which capacitors are listened by the Electroslush) -> VCA/Output. In the long run I might combine the Electroslush and Mikrophonie into the same circuit.
Successfully build a Music Thing Modular Spring reverb mk2 and a Kassutronic ASR Envelope (which also loops, so now I have an additional LFO too!). I don’t have a frontpanel for the envelope, I’ll have to figure something out. Even tough it’s a really simple module, it has been my most complicated build so far as I had to source all the parts (some had very specific measure specifications) and trust my judgment in the assembly. Powered it for testing using a power supply I build earlier. Feeling confident in my diy.
Traded my Drumbrute to a Expert Sleepers Disting mk4 (the trade was balanced monetarily). Disting has a steep learning curve. Got some multisample Mellotrone running using the the J-6 algorithm. Compiled a samplepack for it (cello, choir, flute). Seems that my departure from sample-life was short lived.
