Made my first batch of Faux San Pelligriano. 1,5l water is added with ~2g of salts and minerals (10l has 0,92g Table salt, 5,7g Epsom-salt, 4,8g Plaster of Paris, 1,5g Chalk). Digesting Plaster of Paris aka. Burned Gypsum feels weird but I’m confident because Gypsum is also used in the production of tofu. Epsom salt aka. Magnesium sulfate is a spooky material too but it is used also as a laxative and it’s health benefits are well documented. Chalk and salt feel more safe to use.

Spotted Too Many Zoos online. The baritone saxophonist is called Leo Pelligriano. I want to drink Faux San Pelligriano while playing techno as Faux Leo Pelligriano.

Build an acoustic piezo preamp using a tl071. Used the toner transfer method to etch a pcb following this design (some traces came off a bit weak). The same circuit can also be found as a vero board design. Works well, sounds very clean and even amplifies the signal enough to trigger Bastl Skis. I’ll possibly make a lm386 audio amp as it’s companion, so that I can boost the signal further. I’m also planning to run the lm386 independently so that I can use it to trigger the second Skis channel. Drum triggers in the works! I designed how the two circuits would be linked while attending the Frame Epistemic Hospitality event.

Meritocracy is a myth invented by the rich (2019) Nathan Robinson.

It’s no secret that wealthy people will do nearly anything to get their kids into good schools. But this scandal only begins to reveal the lies that sustain the American idea of meritocracy.

[…] equal opportunity would require a radical re-engineering of society from top to bottom. As long as there are large wealth inequalities, there will be colossal differences in the opportunities that children have. No matter what admissions criteria are set, wealthy children will have the advantage.

Build my first module: “Tip/Ring Thing (Breakout)”. Its a 4hp unit which divides a 3.5mm TRS socket to two separate mono sockets. I can now transmit CVs (and audio) from-and-to my softPop with the module. It’s essentially a passive two channel splitter and/or mixer. It also works with my QuNexus, which sends CV trough a TRS connection. (Building the module costed me less then 5€ but four hours of time, because I wanted the panel from wood).

I’ve now compiled all of the modules I have planned. Feeling content but I want to deepen my understanding of sounds. I need some kind of drum-sound generator (re-discovered Kastle 1.5), a looping envelope, more VCAs (I’ll possibly build them using vactrol), a second LFO (for slow movements), a second attenuverter (for the second lfo) and a spring echo. Today I used the Turing Machine as an oscillator (by clocking using softPops square wave output), I patched the same clock signal to my clock divider (which serves as a square oscillator, when clock very fast). I then routed the sound of the Turing Machine to the softPops filter and used the QuNexus to trigger the Skis envelope/VCA to control the sound (of the filtered sound and the clock-div sub-osc). I wonder.. Would psychotherapy be more affordable?

Build a PMfoundations clock divider. Everything is working well. A moderate build, took me three hours. Also assembled a Bastl passive mult. To my fury its wood panel broke in assembly. Got my QuNexus from the mail and got the pressure sensitive pads working smoothly with my softPop.

Building up stamina for serious work.

Successfully build a Bastl Skis module. Spend my evenings in Kankaanpää Art School by building a scrap-plywood 104hp eurorack case with space for 3u and 1u modules. The case has adjustable support legs, so that it can be worked from an ergonomic position and a lid which can be closed with patch cables attached.

Build a special “3,5mm TRS jack” to “dual banana jack” adapter (with additional female pin headers for grounding the connection). The TRS jack has two pairs of wires coming from it. Both pairs transport a signal (Tip or Ring) and the ground (the sleeve of the 3,5mm jack). The signals (Tip/Ring) go directly to the banana jacks and the ground (Sleeve) is connected to a set of female pin headers, which I glued on the outer plastic shells of the banana jacks.

I added 3 pin female headers to my Lorre-Mill uTone “prototyping area” which connect to the ground (the negative terminal of the DC power connector -> to the negative terminal of the battery). When using the adapter the ground connection can be made using a jumper wire. I’ve used the adapter to connect the uTone with a Bastl Kastl unit. Kastl can send out control voltages via a TRS female connector on the back of the device. It can send out an LFO, random sequencer voltages, gate pulses, etc. Signals can be routed from the top of the device to the left (Tip) and right (Ring) channels (Should there be resistors inside the adaptor?).

I can now sequence the pitch of the uTone and send other kinds of voltages to it’s other input. Sending a gate signal to the input in the middle of the board introduces pretty rhythmic distortions. The only weird behaviour I can identify is that the uTone produces lower tones when powered from an adaptor and more high pitch sound when a battery is used. This might be due to the Kastl, the voltage might drop when it’s grounded. I imagine the connector will work the same with a softPop.

Works well and looks cute.
