Vendor-Independent, Fully Verified, Open Source VHDL Common Library

Electronic and Software (Firmware / Host) for the OpenAstroTracker.

The firmware engineering home of the Cryptohack electronic badge project.

Reverse engineering of the IKEA GETKÅL colour-changing LED string light: decoding its power-line data protocol (pulse-distance coding, 32-bit blocks, 12-bit colour, run-length zones) from oscilloscope captures.

Scientific Toolkit v2.0 is a free, Python-based desktop application that provides an integrated, adaptable environment for researchers, students, and labs with limited budgets. Originally developed as the Basalt Provenance Triage Toolkit for geochemical and typological classification of Early Bronze Age I basalt vessels and artefacts (Egypt/Levant) using pXRF/ICP-MS, isotopes, wall-thickness measurements, and museum metadata, it has been significantly expanded and rebranded.

Now supports 18+ disciplines including geochemistry, archaeology, petrology, sedimentology, soil science, environmental analysis, zooarchaeology, isotope geochemistry, geochronology, spectroscopy, GIS, and more. Key features:

70 rule-based classification engines (e.g., TAS, QAPF, Pearce diagrams, Hakanson risk, Behrensmeyer weathering) 10 multi-stage scientific protocols 37 software plugins + 25 add-ons (plotting, consoles, offline Toolkit AI v2.2, macro recorder) 16 hardware suites for direct integration (SciAps/Olympus/Bruker pXRF, Mitutoyo calipers, balances, pH meters, GNSS, etc.) 16 domain-specific Field Panels with live embedded diagrams and auto-detection Statistical Console (plain-language stats, no coding) Publication-ready templates (Nature, Science, AGU, Elsevier) Project save/load, thread-safe auto-save, and more

Designed for cross-disciplinary workflows, field-to-lab portability, and non-coders. Built by an independent researcher using curiosity-driven development. Validate all results—garbage in, garbage out. Full details: https://gitlab.com/sefy76/scientific-toolkit/ Zenodo Archive: https://doi.org/10.5281/zenodo.18727755
