Oh that reminds me of working at the zoo.

 

They moved the bactrian camels to a new location and put up an electric fence to keep them there. Turns out when a bactrian camel puts on its winter coat, the fur hanging off the neck can be inches thick and is a perfect insulator. The camels walked through the electric fence as if it wasn't there. The wires have to be placed at just the perfect height to miss the thickest fur and the super-thick knee pads they have.

Another military war story ... we had a handfull of those very old, WWII-era field phones lying around in storage. During a cleanup we took some stuff back to the lab, including one of the phones. Those babies can crank some current. We would hook it up to a large capacitor and crank the daylights out of it, then discharge it with a grounding probe. CRACK! Brilliant arcs and the smell of ozone. "Son of a ...!!"Smiley Very Happy

Just wired +5 v out of one device to +5 out of another...the smell and smoke was quite remarkable.

Did you at least connect the grounds first?

I was shopping for computer parts about a month ago.  Picked up a couple of 2.5" HDs, and needed a few new enclosures for them. 

One stack of enclosures had a USB-A female connector on them.

The cable it came with had a USB-A male connector on each end. Smiley Surprised

 

I bought a different enclosure.  I'd rather not smell that smell coming from my computer.

Not sure, all I know is the scb 68 started smoking but the fpga card is good! The problem was the 7841R has 3 connectors, one is RMIO. The RMIO connector doesn't map to the scb68 the same as the other two, and I was loooking at the pin assignments for connectors 1 and 2. So, more than likely, all sorts of stuff was wired wrong.

Quickly wired up a compound node to covert from degrees to radians (I know there is also an expression node in the scaling palette). I intended to wire a Pi constant, but somehow ended up wireing the dice instead. The results were somewhat random and it took me longer than it should to find the problem. 😄
