A working archive of research notes, teardown write-ups, and industry commentary from the Nadchodzi4 team. We publish what we learn in the lab, on the shop floor, and at the terminal — usually with citations, occasionally with a soldering iron nearby.
Long-form notes from the bench. Featured every Monday, archived in the index below.
Six weeks of differential scanning calorimetry data, two failed lots, and one uncomfortably warm fume hood. We compare melt temperatures across three storage regimes, discuss the role of trehalose as a cryoprotectant, and propose a stability budget that survives real-world logistics.

Thermal cycling, flour dust, and one accidental espresso. We pulled apart a unit that spent over a year on a counter in Kraków and graded its repairability.
The directive is final, the standards bodies are still arguing. We map the actual timeline for retailers integrating certified PIN pads before the 2026 deadline.
Circular dichroism is a fifteen-minute test that saves a three-day prep. A walkthrough of our standard screening panel for novel peptide candidates.
We open-source the schematics, gerbers, and firmware for a sub-$40 receipt printer companion. Fork it, build it, sell it — just keep the safety isolators.
Three vendors, four pilots, and a dashboard no one logged into. Notes from a year of trying to make machine learning actually useful at the till.
