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! :>
