MMCedu project - Introduction

Time ago I wrote an article (Toroid tale) about my early experience in programming.
Electronics always fascinates me, especially digging deep about how things works, so ... here we go with some magnetic core explanations/experimentation and a retro-magnetic core building project, for fun and nostalgia lane.

A toroid tale

I'm a software developer, mainly in firmware for many years and still today I really love working on small board in C or assembly. I consider that a "real" programmer job.
Going down on the memory lane (pun intended :) ) it can explains maybe why.
