Cookbooks

Applied-science recipes - the working code, the equations underneath, and the steps to reproduce them on your own machine.

From Datasheet to Review Package: A Runnable PCB Harness

Build a standard-library Python harness that turns datasheet facts into sourced component contracts, composes them into reusable application blocks, and runs deterministic validators - ERC, power budget, ESP32 strapping, antenna keepout - to emit a review package for a USB-C powered ESP32-WROOM-32E board before any copper is routed.

Forge Your Own Blockchain: A First-Principles Cookbook

Build a working proof-of-work blockchain in roughly four hundred lines of Python from four cryptographic primitives - hash functions, digital signatures, Merkle trees, and proof-of-work - and run it end-to-end with real signed attestations and tamper detection.
