Founded in year, 2001 kyberia.sk is the oldest slovak digital community. Awarded Prix Ars Electronica Honorary Mention in 2013 for its unique political system known as "Parallel Democracy Model", Kyberia has its own content-based economy, institutions (senate) , rules of operation (e.g. ostracization) and is still actively used by cca 500 hundred people on daily basis.

Question to plenum: estimated costs after 23 years of operation ?

Brought into existence as a system for collaborative "Einführungveranstaltung" presentations of a study program Kunst & Medien and Visual Communication, Kastalia is the backend for fibel.digital , baumhaus.digital, udk.ai, gardens.digital etc. systems as well as my primary teaching tool.

In sum, what was originally a small "pet project" turned out into the most important work (&structured copy) of my life.

Magic Wand 0 (MW0) is the main teacher artefact issued from the teacher.solar project. In its essence, MW0 is a headless - e.g. no screen and no keyboard - RaspberryPi computer attached and a solar Powerbank which serves as a main server to which students connect during diverse outdoor education (OE) sessions.

RaspberryPi has additional components - notably the GSM module and 4-microphone circular LED Respeaker HAT - attached to it. Software-wise, it runs a Raspbian Linux with additional systemd services (teacher.js, matrix-synapse, Janus, Kastalia KMS, nginx, bluesalsa u.s.w.) in order to provide completely autark OE experience.

The whole system is attached to an awkward piece of wood of unknown origin making the whole setup both piece of art and teacher instrument in the same time. Additional Arduino microcontroller with 12 different sensor types is also attached to the Wand.

MW0 is more closely described in \cite{hromadathree}.
