  • Useful bonus feature

    From Andrew Smallshaw@21:1/5 to All on Wed Aug 31 16:45:20 2022
    I'm just doing some rough prototyping at the minute and to save
    squinting I put a identifying label on the MCU showing part no and
    orientation, from one of those thermal Dymo-style labelling machines.
    What I hadn't anticipated is the bonus feature - these are thermal
    labels so of course give a visual indication when the magic smoke
    gets let out.

    Nice. One time long ago, I got snookered by a damaged prescaler in an
    8-pin DIP. For recompense, I connected pins 1-4 to one side of a 120V
    mains plug, and pins 5-8 to the other. Made a very satisfactory bang,
    and excavated a crater out of the epoxy.

    Most soothing to my irritated soul, and _that_ chip was not going to
    waste any more of my time. (Pease talks about 'Widlarizing' in a
    similar vein.)

    Cheers

    You need stronger adhesive and label material to PREVENT the smoke from escaping! :>

    Many of you may know this but many years ago, I found that windowed
    Eproms can turn into a light if you plug them in wrong. Very wrong :)
