Super Thumper rebuilt again

I was using my 'thumper' the other day and the diodes shorted out.  After looking at the schematic I realized that the diodes were taking the full force of the reverse EMS off the coil.  I changed the schematic to fix that bug.

Also I was able to purchase on Ebay about 50 of 390 uF 400 volt capacitors.  Thats enough to build five of these devices.  Here is what the rebuilt one looks like.

This is what it used to look like before I rebuilt it.

I hope to build another one that will use a 24 VAC AC adapter to power it.  This change will make it even more electrically safe that the current setup.
