RE: Flight Simulator 101, or Back to College - Part 7: Understanding Synchros.

Ah yes, I remember 400Hz Synchros well. Hate the tone today as it reminds me of the constant annoying whine I had to deal with during development and testing.

I used just 12 bits on my 8085 to control them back in the 1980's. Make sure you keep the signals clean with low jitter. A couple of good line filters should do the trick.

Do you have a 3 phase 400hz generator? As I recall they were a little pricey, but are probably available on the surplus market today.

I always found the synchros to work reliably. I built up a software accelerator and decelerator to move it long distances, but you can do fast updates about + or - 2 degrees.

Sounds like a lot of fun, but use your ear plugs.
