+1 Nice work.

Looks like you almost there! And to think you had almost given up.

If Steevsee doesn't have the Zener, there are some at:

Element 14:
http://au.element14.com/nte-electronics/1n5379b/diode-zener-5w-110v/dp/2143709  - Only 74 cents each, but postage will be about $13  , or

From ebay where you can get 20 for $14 with free postage from China, in about 2 weeks  

http://www.ebay.com.au/itm/190918809986

They are listed as 1N5379B, but that seems to be the correct one.

I've had a look, but unfortunately I don't have any. If you were to grab the 20 from China I'd be happy to grab some from you and split the costs to make it more worthwhile.

Cheers,

Andy
