Well, i do not have pictures because i usually do not blow my stuff up. But i have killed over 40 irfp460 mosfets, probably 10 or 20 other random mosfets, I purposely blew a microwave diode up by shorting it across a 12 volt battery, broken many flyback cores, fried 2 or 3 mots, blown up a few capacitors, over 50 ne555's(more like 100's), and just today i blew up two regulated power supplies. There has been much more stuff i have fried, but i cannot think as it is like 1am right now :).

I don't have any pics of the things I have killed because none of the failures were all that amazing. I have killed 2 IRFP250Ns in my ZVS flyback driver. 3-4 555s in my old iggy coil driver (that's when I decided I needed to get a better driver). One MOC because I was overrating the voltage with it resonating with 2 MOTs (connected so it only outputted 2kV). And one random MOSFET the first time I made the ZVS flyback driver (Vds rating was only 60V...)

Imagine 2kJ through a potted LED (the LED was potted in green epoxy).
