another burning diode video.
1N4004
still lights at .8 volts.
varied the supply voltage from zero to 16 volts.
at 1 amp it glows pretty bright.
at 8 amps, well, see for yourself.
note the leads flash, first the anode on the left, then the cathode on the right.
probably the result of more package remaining on the cathode side.

It would be cool to do it again, but use a fan to keep the smoke out of the lens as the diode's burning up.
Notice the tinned leads "flash" at about 0:30 - 0:31
