Projects

Self-hosting

A small stack I run myself: Nextcloud for files and calendars, Forgejo for private git with Actions CI/CD (every push to this site's repo builds and deploys it automatically), Podsync, change monitoring and more, published through a WireGuard tunnel to a small VPS. Weekly automated btrfs snapshot backups with integrity checks and a status endpoint the monitoring watches. No clouds were harmed.

Home Assistant

My flat runs on Home Assistant: a Matter + Thread setup with a pile of integrations and automations quietly tying everything together.

Cloud-free robot vacuum

Cut my robot vacuum loose from the cloud with Valetudo: fully local, no vendor account, no phoning home. It also talks like GLaDOS now.

Voron 2.4

Built from a parts kit rather than bought: a Voron 2.4 CoreXY printer with four independent Z motors and automatic gantry levelling, assembled, wired and tuned from scratch. It has since become the workhorse behind most of my printed apparatus parts — and the cable routing was a project of its own.

nARvibrain ("Augmented Reality supported Functional Brain Mapping for Navigated Surgery Preparation and Education") is an FFG-funded "ICT of the Future" project pairing AI with extended reality for brain-tumor diagnosis, treatment and teaching. At cortEXplore I worked on extending the CORTEXPLORER neuronavigation system to guide functional testing in AR: tracking the TMS and DCS instruments and measuring how the patient responds. Led by RISC Software GmbH, with cortEXplore, FH JOANNEUM and the Medical University of Graz.

The Exploration Room lets researchers record brain activity while a monkey moves around freely. I worked on the markerless tracking and the interaction points the monkeys use, the aim being neural data that isn't constrained to a chair and a fixed task.

A photo of the cooperation box, which took first place in the science category of the DPZ photo competition 2022.

The ZnO project set out to build a zinc–air storage system that charges and discharges at high currents, for scalable island and wind-park setups. I worked across prototype designs, software, the battery-management electronics, and the test equipment.
