Florian Ehmann · Random Nonsense Projects
rad projects & weird ideas

I’m a theoretical physicist
with various hobbies.

This blog is dedicated to my projects — electronics, programming, gardening and more.

Welcome to my little corner of the internet. Expect half-baked prototypes, over-engineered plant sensors, quantum-ish code experiments, and occasional deep dives into nonsense that somehow works.

recent & classic projects

Smart Garden Log

ESP32-based soil moisture logger + weather station. My tomatoes never had better data. Automated watering coming soon (maybe).

electronics · python

DIY Oscilloscope Clock

Turning an old analog scope into a vector clock that displays nonsense phrases and Lissajous patterns. Because why not.

hardware · vga

PermaCompost Sensor

Monitoring compost temperature, humidity and CO₂ with LoRaWAN. The fungi are thriving — data says yes.

iot · gardening

nonsense.sh

A CLI tool generating random physics-inspired ASCII art and experimental bash haikus. Purely useless, entirely fun.

bash · rust

random nonsense archive

From quantum gardening to reverse-engineered toaster UI — these projects have zero practical value but maximum joy.

“Last winter I built a theremin controlled by basil plants. The capacitance changes were real, but the music was questionable.”

categories · tinker forever

Electronics

PCB design, SMD soldering fails, reverse engineering, and my ongoing battle with ground loops.

14 projects · FPGA, ARM

Programming

Python scripts that automate garden irrigation, physics simulations, plus data viz for random sensor logs.

rust · typescript · c

Gardening + Perma

No-dig experiments, companion planting, and using ML to detect powdery mildew (overkill? maybe).

living lab · open data

Physics Nonsense

Visualizing quantum field oscillations with LEDs and writing papers that never get finished.
