I came down and found my spectrum analyzer draped in mylar and paper. It wasn't until I saw the shell in the receiver that I realized what had happened! ;D

Many years ago, at my first technician job, myself and another tech in the lab discovered that if you connected an LED to a power supply, and gradually increased the voltage, it would get brighter and brighter, then dimmer and dimmer, and at some point - BANG! - with bits of plastic shrapnel flying everywhere. (we had tons of excess LED's to expend) AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
We had this young kid working for us in the stockroom, adjacent to the lab, and we could never convince him to wear his wrist-strap when handling parts. We did the exploding LED trick; the kid comes running into the lab, "What was that? What happened?" I said, "John picked up an IC without his strap on," and John, taking the cue, hammed it up, wringing and nursing his "injured' hand. The kid always wore his wrist-strap after that. |
