    Proxmark 3: A Smaller Odyssey

    It all started with a simple question: Can the RFID-tagged filament spools for the new Bamboo printer, which are marked with material type and color for ordering, be copied?

    Sometimes the best ideas come casually

    A few years ago, I already had the idea that you would actually have to digitize in the course of correspondence in the form of letters, invoices and other things.

    The world of single-board computers

    For years, I used Raspberry again and again for various projects or thin clients or retired industrial PC.
