High voltage melting a diode

Melting a broken zener diode with high voltage (1400V/70mA DC).
One HV contact is connected to the diode mounted on a plastic stick (for safety reasons)
The other HV contact is connected to the can filled with a bit of water.
Then, an arc is drawn by dipping the diode into the can. It takes a while to melt the glass body of the diose. The metal wires melt quickly.

i think you deserve a comment for that...i now know what to do with broken diodes!

how did you get the high voltage?

[Coiltec]

The high voltage comes from a ZVS driver with a little homewound transformer.

The ferrite core comes from a broken switching mode power supply.

I added a little voltage doubler (Delon circuit) to the output of the transformer to get the 1400V DC.

how fo you get 1400VDC ?

[kingdeadly1]

I hope you where breathing in the fumes. Is that how ids are getting high nowadays?

[MrAlwaysright1980]

why???

@suupertramp

It actually does, even bigger sparks, juicy fat sparks.

[suupertramp]

nice, however i think high voltage gives off nice sparks and amps doesnt i think :)

@suupertramp

You could go the other way and use amperes to burn the diode, just take a lead-acid battery and short the leads with the diode.
