72 V battery and onboard computer for a small EV
in progress
Building a 72 V LiFePO4 traction battery from
individual cells, with a BMS, for an Ari 458 small electric vehicle.
The next step, currently in the concept phase, is an onboard computer
that turns the car into one with usable information: trip data,
consumption, battery state and cell-level data, and charge control.
Insect biomass radar network
planned
An ESP32-based LoRaWAN sensor network using radar modules to estimate
insect biomass in the field. Nodes are designed to run autonomously on
recycled smartphone batteries with small solar panels and charge
controllers. The hard parts — radar signal processing,
calibration against reference methods, data analysis — are what
make it interesting. The goal is open, affordable and reproducible hardware in the
spirit of HardwareX.
Electrolysis station for archaeological metal finds
built · in use
An automated electrolytic cleaning and conservation device for ancient
coins and small metal finds: an electrolyte bath with graphite anodes
and titanium wire, driven by an ESP32-based smart controller. A web
frontend gives users presets by object type, size, and material, and
different operating modes depending on the goal — gentle
cleaning versus longer-term stabilization.
myzipredict
live
A model and map frontend predicting growth conditions for a mushroom
species across all of Austria on a 1 × 1 km
raster. It combines high-resolution weather and terrain data from
GeoSphere Austria with a
mathematical growth model and renders the resulting probability map.
Runs as two Docker containers.

Forecast verification for Austria
planned
A systematic evaluation of how accurate public weather forecasts
actually are, primarily targeting GeoSphere Austria: collect forecasts
over time, compare them against observations, quantify the error.
Off hours
I use airborne laser scan (LIDAR) data to look for traces of Roman
roads and structures in my home region — amateur archaeology
with terrain-analysis tooling. At home I run an assortment of
self-built sensors (ultrasonic water-level monitoring, home
automation) and solar-powered ESP32 nodes. Occasionally I point a
telescope at the sky and do astrophotography.
