Hi everyone! So, I'm trying to decide if I should interface real instruments for my 727 build or just go with monitors behind the MIP. Has anyone been successful in interfacing a Collins ADI such as is found here? https://www.ebay.com/itm/ADI-Indicator-Flight-Director/183449628182?epid=1953683399&hash=item2ab6732e16:g:7~EAAOSwkkNbJVnM (https://www.ebay.com/itm/ADI-Indicator-Flight-Director/183449628182?epid=1953683399&hash=item2ab6732e16:g:7~EAAOSwkkNbJVnM)
If this is possible then I am leaning toward this as I really love the old steam gauges!! Thanks!

Hi Woody,
You need to talk to Rob Archer (727737Nut). He built a 737-300 with real gauges and x-plane.
Definitely doable, and as Kyle said: Rob A is the resident expert for the older steam stuff.
I will say that you can pick one of those up much cheaper than the one you posted, so do a bit of shopping around.
There are also some great Facebook groups for used instruments and cockpit parts, its amazing what shows up in them from time to time !
Doable.
There are two ways to achieve it:
- ARINC cards to comunicate to instrument. So you don't need to modify them. I know nothing about this, but I think is expensive, and not very easy.
- Mod the instrument, and interface it with arduino/teensy... or similar. Cheaper, but not very easy neither. And you will kill the original gauge state, so only for people whose religion allows it .
I have fully interfaced a real bendix king HSI 525a + slave switch ka51b, and an RMI in this way. Now I am interfacing a real collins hsi 331a. You have to play with synchros (or change them with absolute encoders), d'arsonvals, pots, dc motors.. etc Each gauge is like a new adventure. You don't need a lot of money, but you really need some skills and A LOT of time.
Arturo.
Or, just have guys like Arturo vacation at your house for a week or two and do the gauge for you! And Woody, since you're a pilot, could you get discount airline tickets? Plus, I am sure he would love a free trip to the USA!!! :idiot

Hi,
If you want to do this, have a look here:

Thanks for all the replies! I posted that eBay listing just as a reference for the type of ADI that I was interested in using. Thankfully, I was able to find one much cheaper! It is good to know that it is possible, so I think I will go the steam gauge route! Of course I know this will mean added expense, time and complication to the project but I really want to see those old instruments working again. That is just too cool!
