Hi - found y'all from google ...

Hi!

I landed in here searching on a newava transformer and found Art's SPDIF thread.

See, what had happened was I had a circuit to couple a digital pulse from an embedded controller to drive an ignition system. The success started when I cannibalized a transformer from the fax modem circuit in a Brother MFC printer/scanner. There's a write up and circuit diagram here on StackExchange. Any other kind of driving of the ignition module would result in a noise spike that would reset the MCU.

When I disconnected my test rig and soldered everything in a proper testing rig, that transformer opened on the primary.  :( So I'm going to pick up a newava (and a couple other transformers) from Digi.

If anyone happens to glance at my circuit and have suggestions based upon their experience, please let me know where I'm going wrong.  :lol:

Thanks for Art's thread,
Chris

Greetings & Welcome to AC Chris   :thumb:  Here's hoping you achieve blast-off ?  :scratch:  Or success with your ignition issue in any case.  :D
