Title: Hi - found y'all from google ...
Post by: unexpectedly on 17 Oct 2019, 08:32 pm
Hi!

I landed in here searching on a newava transformer and found Art's SPDIF thread (https://www.audiocircle.com/index.php?topic=45330.160).

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 (https://electronics.stackexchange.com/questions/452219/mimic-a-pick-up-coil-to-drive-a-cdi-ignition). 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
