Disabled the Auto WiFi hotspot script on my Raspi following the Script Removal guide. Using the Raspi as my studio terminal… Yeah, I build a studio over the last two weeks. It’s a small room (240 x 230 x 235). Originally a compartment of the mandatory civil defence emergency evacuation structures of our apartment building. It’s below ground level but has a cute window trough which I can see the grass. In the summer I can turn this space into a camera obscura!

I build long shelves, two tables (one for standing and the other for sitting) and a weird high work stool using a Brooks-bicycle saddle and timbre I salvaged from a nearby construction site. The tables and shelves run along the walls and are mounted straight to them (made from OBS hence channelling strong 2000-berlin vibes). I’ve used every corner of the space and even added a sitting hammock to the ceiling. I got everything ready just before I was relieved from my gig-job at Posti. Still recovering from the gig.

I haven’t used the space much yet and there is still some work to be done. I’m currently moving all my gear, tools and supplies from the closets I’ve used to stash them. Dismantled the WaterLab patch (made notes of it) and organized my modules to the two cases I’ve build. I can finally test CaliOSC with the Mutable Instruments CVpal with my Norns (running Orca). The hammock is positioned perfectly for working a keyboard/Norns and to send signals to the modular.

Oh.. What a weird and wonderful night. I was exited about assembling the walky-talky modules and went on imagining of scenarios I could use them in. An idea gloomed.. What if the module would work in FM domain? I’ve been making radio experiments with my raspi (see Hammeradio) and the itch to send wireless signals is an old one. The question led me on a frantic internet search stream and eventually I run into a website I visited years ago: Polimorphous Space by Tetsuo Kogawa. I learned about the site from Diego Cruz Martinez an activist/engineer who worked for/with Radio Oaxaca. I interviewed him when I was working for M2Hz and the interview in available Finnish: Ääni intiaanikylille (2009).

Kogawas site is fascinating. There are texts and interviews dealing with the work of Félix Guattari (whom Kogawa met in 1981), manifestos and poetry, bundled with technical notes and schematics. The radio art guides he offers are thorough and the radio transmitter builds seem very robust. Here is a quote from his Micro Radio Manifesto (2006).

Today, our microscopic space is under technologically control and surveillance. Our potentially diverse, multiple nad polymorphous space is almost homogenizee into a mass. Therefore we need permanent effort to deconstruct this situation. In order to do this, to use a very low-power transmitter is worth trying. Small transmitter can be easily made by your own hands. [SIC]

This is a direct call for action and aligned with the texts he offers, this sets a clear trajectory for critical radiophonic work! The looks of his builds are wonderful. He uses an adaptation of “Manhattan style” method in his circuit construction (some notes on the style on Parasit Studio blog). The name Manhattan style reflects the street grid and urban planning of Manhattan, New York and I guess it links to the era of the Manhattan project too.

I’m now dreaming of building an eurorack unit of “the standard model” transmitter in Manhattan style. Some components are rare (2SC2001 transistor) but he also offers plans with alternative components (BC337 transistor). I imagine that in a rack the transmission would cause a lot of noise and interference but the build is conceptually firm. I think that as a module it reflects and is a call for the “responsibility of speech”. I’ve come to believe we have a responsibility to make sound, to voice opinions so that we do not collide to each other. This idea is well drafted in a boating story I heard from Topi Äikäs. In short: “If everybody is silently looking for the truth, nobody is safe!”. I could etch this story on the PCB.

After an exiting couple of hours in the world of Kogawa, I realized that the module should also include a receiver: Whats would be the point in making noise if no-one can listen to it. After some search I found this Simple FM Radio build (credited to Charles Kitchin) which is simple and runs on the same voltage as the transmitter (the unit in the photo is also build in Manhattan style). This means both builds could be powered from the same supply! I’ll have to experiment if this will cause too much interference but the idea is clear. The module could have one input for transmitting and one for receiving. With two modules, two (or more) racks can be made to work in unison.

An additional bonus in the transmitter build is that I could use DIY mineral water capacitors (which I experimented with on the Simple EQ build) for setting the transmission frequency (it needs a variable capacitor between the values of 10 to 20pf). This is perfect because when working on the walky-talkies I felt horrible remorse for not continuing to develop/build modules I’m planning to use in upcoming mineral water performances. Suddenly a side quest to radio transmission domain proofs meaningful and everything makes sense for a while.

Better than Zoom: Try these free software tools for staying in touch (2020) Greg Farough. List of open source tools for communication, file sharing etc. I’m tempted to experiment with Raspi as a home server. It might be worthy as a model for free culture distribution! Although I think publishing art for the sake of art is of bad taste right now. Might be cool for easy fun chatter thou.

A spicy application I drafted for the Together Alone open call was a bust. Only 5 out of 130 were funded. They’ll keep my proposal in their register for the next rounds of applications but it’s a stretchs. I hope they got a laugh or inspiration out of it — I bet they did. I’ve been sending an application a day and speedrun my tax-report in four hours (not much to report I guess).

Our In Various Stages of Ruins: Denial exhibition at Alkovi is now accessible at Helsinginkatu 19 and online. Feels good to do stuff.

The Mazizone local network archive I’ve been setting up for my Raspi3+ is stable and working well. I have occasional problems connecting to it and I need to “forget” the network to reset certificates. But this only happens when I’m login in and out intensively for tweaks & edits. The device reboots daily to prevent these kinds of clogs. I haven’t gotten Gammu (to produce daily status updates via sms) working but with the reboot cycle enabled I’m confident that the device will run well enough.

I build the sound archive using wordpress and it looks fresh. Using wordpress in Mazi causes issues with the network url but this is manageable (it redirects visitors to portal.mazizone.eu which is ok for me). I’m now planning to build a funky case for the device and to make an inviting sign which will guide visitors to the network and archive. While making the website I got the idea of using ornamental patterns as illustrations. I also used ornaments in the eurorack case I build for the trip. When I was designing the case I tough the Byzantine style decorations as a reference to early natural sciences (which my work on mineral waters touches). This spawned the idea to add ornamental figures to the thumbnails of the sound files in the archive.

Each sound file (53) has a unique photo assigned to it. The photos set a mood for the content and give a hint of the sound. Photos were shot during our train trip by Iona Roisin, Elina Vainio and Miina Hujala. On top of each photo is a layer of different ornamental shapes. They twirl around the thumbnail corners and interact with things and people in the images. I’ve used Kid3 to add the images to the .wav files. If I’ve understood correctly .wav’s don’t have thumbnails but Kid3 manages to embed the data anyway. The default wordpress media playlist widget can source the images from the files and display them next to the track info.

Now there are ornaments everywhere!

I like over the top ornaments which have an abundance of detail. In Russia I can spot them everywhere. They are used in architecture (Corinthian pedestals and window frames), street lamps, fonts, advertisements, jewelry and clothes. Sometimes the patterns look familiar. Shapes I’ve seen in Russia appear to fuse Byzantine style decorations with folk ornaments I worked with during my carpentry studies. I can recognize a patterns being identical to a traditional woodcarving I’ve seen in Finland. Pirtanauhat and kauluslaudat are good examples.

I guess ornaments appeal to me because they link traditional Finnish crafts with Byzantine history and even contemporary Islamic and Arabic cultures. We visited a folk culture museum in Kazan and many of the Islamic artifacts in the collection looked similar stuff I’ve seen in Finnish folk culture museums (particularly the wooden objects). Some of the clothes looked like something my mother would want to wear. Styles I link to Bedouin folk gowns that are decorated with coins, felt really similar to Russian military uniforms which are decorated with medallions.

The ornaments I’m using for the archive and the thumbnails remind me of weeds. I think they link the archive to “ruins” which Miina is interested in. I think ornaments should be read as celebration of decay. They simulate nonhuman futures by imagening how plant life will take over architecture. They feel like archaic glitch art! Sometimes ornaments in clothes look like roots or blood vessels. I think Scandinavian design aesthetic read ornaments as a vanity but if we approach them as a celebration of decay there is nothing vane in embracing them. I hate Scandinavian design because it makes me feel ashamed of my appetite for details.

Using ornaments to decorate a sound archive, which is difficult to access – Feels right and embedding weed-like ornaments inside metadata makes sense. Here is a low-resolution sample of what the archive looks like when browsed using a mobile phone.

What an exiting day. I got a Mazizone installation running on my Raspi3+! I can now host a local access etherpad service, open a file sharing box or a wordpress installation (among other things). Here is a short explanation why these kinds of “Digital Sovereignty” projects are important. (The project also has a faint link to urban farming, as one partner for the project has been Prinzessinnengarten) Feels great and only took 10 hours of manic computer work to figure out. I’m preparing to share my Trans-Siberian Railway sound collection using a Mazizone which is specifically set up for the Alkovi space at Hämeenkatu. Here is are my notes on getting the system running for this setup.

  1. Etcher > mazizone-v3.1.1.img (or 2020XXXX_alkovi-mazizone.dmg)
  2. SD card to RPi3+, boot and wait for ssid: mazizone
  3. Setup (Set location: lat, lon 60.187174, 24.953562) and change password
  4. Expand Storage > Reboot
  5. Browser to local.mazizone.eu:4567/admin > Disable unused apps
  6. Set USB1 wifi dongle (panda06) for “Internet connection” and set “Internet Network Mode” to “online”
  7. ssh pi@10.0.0.1. Change password using raspi-config and sudo apt update > sudo apt full-upgrade and reboot
  8. Setup DS3231 clock for stability. Sudo apt-get install i2c-tools, set locale using raspi-config and configure module using ssh. Guidelines for battery setup (in short supply it 3,3v).
  9. Applications > WordPress > Set up WP (don’t mess with the URL settings in WP)
  10. Change WIFI ssid: Alkovi (no password) and reconnect
  11. Change Portal Domain “in-various-stages-of-ruins.eu”
  12. Assign WordPress as “homepage” and set bigger upload file-size via Admin > Settings > Apache max file size: 500M
  13. Don’t change WordPress url (Test if changing step 8 order would help in clean urls for wp. Edit: no effect, see: Changing domain for wordpress not possible.)
  14. Update WordPress and themes, make them pretty (one page for sound, one page for info) and upload Trans-Siberian railway sound collection.
  15. Setup cron for daily reboot cycle:  sudo nano /etc/cron.d/alkovirebootcycle > 15 2 * * * root /sbin/shutdown -r now
  16. Add > dtoverlay=pi3-act-led,gpio=19 to /boot/config.txt to allow sd-card activity to be shown on an external red-led (protected with 470Ω resistor for good measure).
  17. Make duplicate of the SD card as backup.
  18. Test everything, break everything and re-do everything.

Later: External shutdown button (python?), how can I get it to “sms report home” (will old Huawei E1550 I’ve stashed work out of the box or should I configure it somehow?). experiment with PiFmRds(?) and enjoy.
