What Radiona / Zagreb Makerspace does
Radiona (legal name: Udruga za razvoj 'uradi sam' kulture – Radiona) is a Croatian non-profit association founded in 2011 in Zagreb, operating as a community makerspace dedicated to the development of DIY culture, open hardware, sound art, and bioart. The organization serves a diverse constituency including individual makers, K-12 students, educators, artists, and the general public, delivering value through hands-on workshops, artist-in-residence programs, exhibitions, and educational materials. Its core technology stack is open hardware: Arduino and Raspberry Pi microcontrollers, FPGA development (including the FPGA ULX5M board), DIY synthesizer prototypes (Synthomir 8-bit synth kit), circuit bending, 3D printing, and biohacking tools. Notable product offerings include the Synthomir DIY kit (€30 unassembled, €50 assembled), the Theremin Postcard educational kit, and the ZigZag e-Badge developed for BSides security conferences.
The business model is grant- and contribution-driven rather than commercially scaled. Revenue streams include workshop fees (50 kuna for members/students/unemployed/retirees and 80 kuna for employed participants), DIY kit sales via email order, and — most significantly — EU project funding through Erasmus+ programs (Creative School, iNTANGIBLE, STeam/STeMfemme Junior), grants from Zaklada Kultura Nova, and support from Croatia's Ministry of Culture and Media. Commercial partners include A1 Hrvatska (STEMFemme Junior funding) and the Repair Café International Foundation (network membership since October 2024). Distribution is community-led: Open Lab sessions (Monday and Wednesday 19h), direct delivery at partner schools and museums, EU project venues, and international conference appearances (BSides, DORS/CLUC, BalCCon, Electric Wonderland). Headcount is 7 employees with no disclosed private equity, venture capital, or controlling shareholders. The organization is operated by key members including Deborah Hustić, Goran Mahovlić, and Damir Prizmić.

Radiona / Zagreb Makerspace competitors and assessment
Company assessmentBroad incumbents
- Ars Electronica: Austrian cultural institution and festival for art, technology, and society. Already a Radiona partner in Creative School; comparable as a much larger European institution blending technology education, art exhibitions, and EU-funded programs.
- FabLab Foundation: Global network of digital fabrication laboratories originating from MIT's Fab Lab program. Operates a much larger maker-education ecosystem with similar workshop-based, community-driven models but at a global institutional scale.
Emerging players
- Gijs Gieskes: Independent Dutch designer of experimental electronic instruments and sound art. Recent Radiona artist-in-residence; comparable as a niche individual maker producing open-design audio hardware in the same DIY synthesizer scene.
Direct peers
- Opendot Lab: Italian fab lab and makerspace focused on open-source digital fabrication, education, and creative technology. Comparable as a small European community makerspace with EU project participation and educational programming.
- Repair Café International Foundation: Dutch-founded global foundation coordinating volunteer-led community repair events. Radiona joined the network in October 2024; directly comparable in mission around right-to-repair and community skill-building.
- Critter & Guitari: Brooklyn-based maker of experimental electronic musical instruments and DIY synth kits. Comparable as a niche hardware maker targeting the same overlap of music, electronics, and maker-community enthusiasts.
- Bastl Instruments: Czech-based maker of DIY and compact modular synthesizers and electronic music instruments. Directly comparable as a small European producer of open-design, hackable sound hardware with an education- and maker-community focus.
- Hackteria: International open-source network for art, science, and biohacking collaboration. Radiona explicitly participated in Hackteria's 2011 DIY biolab workshop, and both organizations operate at the intersection of bioart, open hardware, and community education.
- Noisebridge: San Francisco-based volunteer-run hackerspace. Comparable as a community-operated makerspace offering open lab access, electronics workshops, and a DIY culture ethos, though operating at larger geographic and demographic scale.
Regional players
- Ljudmila Lab: Slovenian hackerspace and creative-technology lab in Ljubljana. Regionally comparable as a neighboring Central European maker organization with similar open-hardware, art-tech, and community programming.
