A hands-on journey through the design of an analog transmitter that converts 0–20 mV into 0–10 V and 4–20 mA using filtering, amplification, scaling, and voltage-to-current conversion.

Technical analysis of a generic FIFO/LIFO library for Siemens S7-1500 in TIA Portal using SCL. Supports generic payloads through VARIANT and serialization.

Continuization and an intuitive explanation of the square law: ODEs, control, norms, reachable sets, causal cones and Hamilton–Jacobi, with rendered LaTeX.

Demystifying the square rule in chess: from visual trick to reachability in graphs, the L∞ metric, and inequalities in discrete space-time.

A tool to export TIA Portal projects into a deterministic, Git-friendly XML structure using Openness — so Git stops screaming for no reason.

A practical, honest mapping of OOP design principles to Siemens TIA Portal using FBs, UDT interfaces, composition, and stateless FC helpers — with equivalent C# code.

Little-known TIA Portal shortcuts like F7, Shift+F12 or Ctrl+B that dramatically improve daily workflow.

Chess and PLCs seen rigorously as finite state machines: formal definition, a chess model, a PLC model, and practical design principles.

A lightweight Windows CLI utility to rename files, search text, replace content, and undo changes—no dependencies.
