I was thinking about breadboarding a simple 30 Hz square wave oscillator and connecting it to the tach input. You could scope the signal to see if the tach is loading the oscillator too heavily. Based on what we see we revise and retest.

We can build an oscillator with parts like a LM555 or almost any general purpose opamps. Have any parts floating around?

We probably should start a separate thread. We've completely hijacked this one. :oops:

Sorry Bob.. Moderators can move the last several post to new thread if they like.

No problem to me Rob - It's all good interesting stuff related to interfacing real aircraft instruments as far as I'm concerned!

However, I suppose it's not synchro, so good idea to split the topics - It keeps things tidy anyway.

I'll continue this one when I have more info.

Cheers,

Rob
