ACTIVE01
Celina’s instrument cluster
A custom add-on display and LED architecture for a first-generation Citroën C1, built around optical sensing, CAN, and an ESP32.
- ESP32-S3
- CAN FD
- ST7789
- lots of tiny LEDs
available for interesting problems
Electronics, embedded systems & useful nonsense.
Made Possible™
I design hardware, write software, automate repetitive engineering work, and occasionally make existing objects much more sophisticated than their manufacturers intended.

Selected projects
Things currently consuming electrons
Real engineering, active prototypes, and a restrained amount of chaos. Supervised & approved by real bunnies.
UNREASONABLE04
Unclassified prototypes
Adapters, dashboards, fixtures, sensor experiments, mechanical crimes, and other objects whose purpose becomes clear eventually.
- CAD
- fixtures
- reverse engineering
PROTOTYPE02
Tiny reflow laboratory
A small oven, custom sensing and control, and the inevitable question: “why did the original controller not already do this?”
- thermal control
- ESP32
- profile logging
SHIPPED03
Engineering tools
Small internal web tools that turn repetitive copy-paste workflows into something considerably less hostile to human life.
- automation
- data QA
- web UI
Capabilities
From vague problem to working object
I’m most proficient where hardware, software, research, and practical constraints collide.
Hardware architecture
Requirements, component research, interface design, power trees, and system trade-offs.
PCB design
Schematics, layout, compact assemblies, production details, and design-for-debug.
Embedded software
Firmware, device interfaces, displays, data logging, configuration, and prototypes.
Test & automation
Tools that reduce manual work, reveal bad data, and make engineering flows less fragile.
Prototype integration
Electronics meeting enclosures, wiring, mechanics, real objects, and inconvenient geometry.
Technical investigation
Datasheets, obscure parts, reverse engineering, fault finding, and structured uncertainty.
About
Curious, exacting, and suspicious of unnecessary repetition.
I’m your name, an electronics engineer based in Warsaw, Poland. I like compact systems, strange constraints, clean schematics, practical automation, and learning exactly how something fails before rebuilding it properly.
The rabbit is not management. Its role remains under investigation.
make it understandable
measure before guessing
leave room for iteration
Contact
Bring the strange problem.
Here, the motto is simple: Make Possible™. Collaboration ideas, hardware questions, prototypes, and broken objects with unresolved emotional baggage are welcome.
