Tuning my Patching Panda Operat (assembled last week) took some figuring. When the symmetry control was set perfectly in the middle and oscillation barely audible, the process failed. After failing numerously, I positioned the symmetry knob not-perfectly and sent a midi C1 from a daw via Keystep 32 CV out to the module. I send the audio back to the daw and read its tuner, turning the multiturn potentiometer (marked C1) until the tuner read 32.7Hz. I then sent C8 and turned the other potentiometer (marked C9) until the tuner read 4186Hz. I then sent C1 and C8 again, repeating the process 5-8 times until each C in between was in tune. I think C8 is the maximum for the Keystep. I could have executed the 9 Oct tuning between C0-C8 but the daw tuner couldn’t reach C0.

After tuning the EXP, TZ-FM, RM-AM etc. jacks ceased to work for a while and it took a reboot to get the module working.


Converted my Crescent 307 into a single speeder (52/16 for now, will go for a 19t 18t cog later) after fitting it with used Mavic Aksium rims. Got a chain tensioner for it too (might not need it though). Assembled a 7 gear bike by combining four different bikes on a salvaged Helkama Jääkäri frame. It’s got a front dynamo hub and a lamp too. Fixing the Shimano Nexus gears was difficult and I used bits from a CJ-NX10 to replace parts of a CJ-NX40.

The ratio 4 to 1 is interesting. There are one billion bikes in the world, if production halted for 40 years (which was the age of Jääkäri frame) we could still have 250 million bikes!

Learning how to roast Yirgacheffe beans. Bought 25kg raw from Kahvitukku ABI early in the spring. I need a new hot airgun to maintain roasting temperatures.

Fixing eurorack modules for friends and servicing a Neve preamp.

Working as a janitor for our housing company. Yet, living on savings.

Living the 31 year old expat in 2012-Berlin lifestyle.


Assembled a short range short wave transmitter to experiment with the RF Nomad. Spotted into an interesting Frequency Range Mod for the module and a nice introduction to SW antennas by N4UJW (the scale of which is out of my reach). Mic-pre (2022) ramphands would be a great companion for a FM transmitter.

Feeling overworked but not even doing much. I fear I wont have time to fix the Radio Kid revision this summer.

Enjoyed Crimes of the Future (2022) David Cronenberg because it was so close to base that I could snark at the romantic portrayal of artisthood and the blatant critique of art institutions. Portraying artists as snitches for the status quo and opportunist piggybacking on the wings of revolutionary social movements felt accurate. (or perhaps the plastic-eaters manifested the start-up industry) The feeding-machine was a beautiful depiction of lactose intolerance –like hindrances.


Martin Howse gives a thorough introduction (2022) to their line of eurorack modules. I like how simple the functions are: Noise is made from a laser passing smoke, picked up by a light sensitive sensor and amplified. Simplicity makes it easier to digest the conceptual frameworks the modules spring from. And the conceptual frameworks are made accessible using simple narrative hooks. But Howse’s narrative devices are whimsical. They offer anecdotal snippets to research, which spark curiosity – But simultaneously establish an authoritative tone. Loose references to research build up the appearance of an gray-intellectual-figure, a sense that there is deep and firm knowledge underlining the whims. I don’t like this tone because it feels authoritative and non-negotiable, like a ghost.

There was an interesting audience question (1:02:37) whether Howse’s modules make up a system, narrative or an ecosystem. The question is impossible to answer and nice to ponder. Touching and effecting code and electronics with naked birth-flesh sounds complicated and inspiring but thinking about it… It is what we are all doing all the time with our devices. They have also attempted to transcribe fiction into functional code, which feels like a great approach to teach coding! Orca could easily be made into a world building exercise or possibly even a simulation.

I came acquainted to the gray-intellectual-ghost trough the placement of an introduction text of the Skills of Economy exhibition at SIC in 2014. Jussi wanted to attach a curatorial statement text on a huge sheet of metal, left leaning casually against the gallery door. I don’t think anyone read the text because it was placed like a leftover – But the text was critical for establishing a sense of certainty and intent to the array of artistic nicnacs we as Ore.e Ref. supplied.

An easy to read summer horror story and the earth drank deep (2022) Ntsika Kota. I like the tone of the text. Easily written stuff enables imaginative reading.

I should built a Mixor Image by modular-maculata.



When sourcing parts for a RYO Paths module, I discovered that the Fairchild FJN3303R NPN Transistor is no longer manufactured. Searches on Octapart indicate that some companies still have the transistor in stock but they unfortunately only sell the chip in big batches. A company called Rochester Electronics would only sell me 12940 units and AVnet 16026. Both companies seem to supply electronic components for the manufacturing industry. If someone were to build over 5000 Paths this would make sense (the module requires three transistors). Modular grid indicates that around 700 users have the module already, so I imagine the market is saturated by now. The module seems to be from 2015 and there are dozens with similar functionality available. Perhaps 5000 sequential switches could be used to build a computer of sorts.

There are some potential substitutes for the transistor but I’m not skilled enough yet to confirm if the specs are a match. So I turned to ebay, aliexpress and other dodgy vendors. Some claim to be selling the same transistor but the price of a single unit is over 10€. It is also impossible to confirm that the chip is the right one.

Luckily the Modwiggler forum has a DIY Trade Thread [ Parts, PCBs, Panels ] where users announce stuff they are looking to trade with others. I found two entries both from 6-7 years ago from users indicating that they had some transistors to spare. I contacted one, got no reply, contacted the other and got a reply, and then the first contacted me too. Now I’m expecting to get 20 transistors in the mail! In a brief exchange we agreed that I’ll commit to distributing the extra units for builders/hobbyist from Helsinki. I got the units for free and I’m committed to distributing them further asking nothing in return.

It turns out electronics as a hobby is about supply chains, archivist practices and social commitment. Turns out hardware is about care. The module is interconnected by design and its manufacturing depends on the good will of other builders. For me the rarity of the transistor is now a facevalue of the module. It makes me a part of the Fairchild FJN3303R NPN supply chain, a member of the rare transistor-gild!

In the process I also learned of the phases of the ljunggrenaudio/RYO eurorack manufacturer. A few years back (between 2016-19) they gave up on business due to health concerns and disappeared.  As their website ljunggrenaudio.com went down and got squatted, the schematics, technical notes, build manuals and patch notes were lost. In recent years the hobbyist community and their past collaborators have sourced the lost documents. They are currently housed on modwiggler and other sites. With out the documentation servicing and building the modules would have been difficult.

The short online-amnesia caused by lost documentations, the rarity of the transistors and the fate of ljunggrenaudio/RYO make the module build process more then a mere assembly (which most DIY kits are). It feels almost like a media archaeological excavation. I would like to learn more about the transistor thou and other things it is used for. I’ll distribute the Fairchild chips I was handed via Ore.e Refineries. I’m amazed by the realization that electronic components, chips and the logics, behaviour and functionality they poses are so finite. Already noted this when I started electronics as a hobby and it feel great to return to this with the Ore.e Ref. Fairchild supply initiative.
