We build, test, break, measure, and improve the tools behind better making.

| Project | What it is | Status |
|---|---|---|
| Jump Jet | A PCBWay-sponsored ESP32-S3 chamber-heater electronics and firmware project for the Prusa CORE One family. | Cold-safe firmware foundation; heater actuation is not implemented. |
| DragonSniff | Local, read-only observability and evidence capture for Dragon-family devices, with optional PrusaLink telemetry. | Active developer tooling. |
| DragonBench | An ESP32-S3 lab instrument for deterministic electrical-characterization workloads. | Early hardware-validation stage. |
The TechBenders sits where maker curiosity meets engineering discipline. We publish the useful parts: firmware, fixtures, test evidence, design decisions, failure modes, and the boundaries of what has actually been validated.
That means our projects aim to be:
- measurable — claims should be backed by tests or clearly labeled as unvalidated;
- buildable — documentation should help another maker reproduce the work;
- honest about safety — browser controls and happy-path demos are never substitutes for proper electrical, thermal, and mechanical safeguards;
- fun to follow — serious engineering does not require taking ourselves too seriously.
We share prints, prototypes, shop experiments, and the occasional beautifully educational failure on TikTok.
Just two dudes who like 3D printing—and keep bringing test equipment to the party.
