ah yes you mean my magic 8 ball?? well It was the best deal ever. I got 
from a scrap/surplus place here in town..
I think I only gave 50 bucks for it..
the HSI well thats an ebay thing over 100 bucks :(
I still need aircraft mounts for both of the dam things..$$$$ ( 
http://www.avionicsmounts.com/ ) or
  ( http://www.msp-aviation.com/index.php?cPath=1_8 ) or get lucky on 
ebay..


I am actually looking into reading synchro phase signals with an Arduino 
now, so I may soon be able to drive and read synchro instruments 
directly. That would save hacking up ADF heads and other synchro 
instruments. I'm having to pack a lot more new knowledge into my brain 
though! :P Matt
Its not quite that simple I dont know if it has dah juice to do the 
job.. you could use the Ti part (they changed the name )
Tiva^(TM) C Series TM4C123G LaunchPad EK-TM4C123GXL  $12.99 LOL

https://estore.ti.com/Tiva-C-LaunchPad.aspx

remember you home its just a TX ie 1 stator field and Y connected 
rotor..  go to my blog to see the thing.. (understanding)
http://www.element14.com/community/people/phoenixcomm/blog/2013/04/29/nexgen-flight-simulator-understanding-syncrhos

2 choices:
1. generate a 3phase (at whatever freq/voltage)  then just look at the 
output  (remember 4 quadrents)
2. generate a single phase (at whatever freq/voltage) then decode the 3 
outputs..
YOU CHOOSE!! me im lazy and pick 1. run the dam thing backwards!!

my blog post was based on a paper i did in school (lots of ugly math) 
maybe one day I will write it.. 2ed. and put it up for others to see... LOL


enjoy
Cris H..
