Projects
Things worth building, even when buying would be easier.
FiddlerCrab is driven by STEM curiosity and the true maker instinct: sometimes a thing does not need to exist, but wanting to understand and build it is enough reason to spend the weeks and the money. Commercial sense is useful. It is not the only reason.
FiddlerCrab
Maker projects, tools and experiments.
CAD, electronics, firmware, small apps and games, built because the question would not leave us alone.
Small machines with a point of view
- PrintGlowPrinter status lighting, website coming soon
- PrintDeckPrinter monitoring station, website coming soon
- Elise's desk clockA personal electronics build
- Analyser projectsGas measurement, enclosures and careful setup
Small apps that get out of the way

In developmentWhat we do
If it can be built, we build it.
CAD and physical design
Parts, adapters, fixtures, enclosures and the tolerances that make them work in the real world.
Microcontrollers, electronics and firmware
Arduino, ESP32 and other platforms, from a first sensor reading to a device people can actually use.
Small apps and connected tools
Focused software for browsers, local networks, workshops and the machines beside them.
Games and playful systems
We have recently started building games too. The first launches are coming soon.
PrintGlow
Printer status you can see from across the workshop.
An electronics and firmware project using an ESP32 lighting controller, printer-aware effects and a physical presence that makes status useful without opening a laptop.
Website coming soon
RGBIC strips, local setup and the physical details that turn status into something you notice.
PrintDeck
A touchscreen station for the printer bench.
A dedicated monitoring station for local printer setups: live status, progress and a readable view of the machines that are otherwise hiding behind their own software.
Website coming soon
Touchscreen hardware, printer data, setup flows and a bench-friendly interface.
Personal build
Elise's desk clock.
A small desk clock project for Elise, because a personal object is reason enough to design the case, tune the electronics and make the details feel right.
Project page to come
One of the next projects to be documented here.
Curiosity is a valid brief. Sometimes there is no practical need for a thing. Wanting to understand it, improve it or make it ours is enough reason to build it instead of buying the off-the-shelf solution.
