Gene,

> Back in my early tech days we used to blow up LEDs for the heck of it at work. We had a 5-volt gazillion-amp power supply that had voltmeter cables on it for destroying hard-to-find short circuits on newly assembled circuit boards (we called it the "f*ck-you" power supply). The LEDs would pop like a .22 going off and the pieces would go "tink" all over the lab - eye protection needed. We did other silly things too like pour solder from the solder pot into vaious molds like coffee cups and burn things up with heat guns but that's another story.

Now, fill in the gaps here. We do need the other story. Also, what modern
unorthodox practise do you perform in the current lab?

Had a quick look at the backplane OCXO while the hood was of the new 1600T.

A colleague of mine have been made more or less destructive testing of the
-48 VDC input blocks. The fun started when he finally did what I proposed and
started using one of our 70V 90A power supplies. More sparks, flying pieces
with associated accoustical effect from his side rather than the smell of
slowly burning resistors.

Cheers,
Magnus
