Great teardown! That was definitely air transport class avionics. Sperry made a whole series of this model indicator to satisfy individual customer requirements. Rising runway was an option, color of the sphere, the use of one or two lights at the top of the indicator, etc. Sperry made several models for the DC-10 and the System Schematics revealed the pin functions and have simplified schematics of what is in the indicator. After wiring up the DC-10 indicator, per the DC-10 document, it worked as predicted. Pitch and roll are synchros, of course, and are used in the DC-10 indicators as well. The guts of the Sperry indicators I have look just like yours. Same module configurations and chassis construction. I then found that when I connected to other Sperry ADIs with the cable I made for the DC-10 indicators, that these indicators share a great deal of compatibility. The pinouts between the DC-10 version and the 747 version were almost identical. The critical pins that seem to appear on this class of Sperry ADIs are common. Pins such as power input(s), internal 5 volt lighting inputs, pitch X,Y,Z and roll X,Y,Z don't seem to change between models. There is even some commonality in the pins in Collins tape-type ADIs. I wish there was a way to send you just a few diagrams so you can do what I did without having to trace through all those flex circuits. If there is a way, let me know. I acquired quite a few of this series of Sperry ADIs since I needed to make sure I had spares for my 747 simulator cockpit. Changing modules is easy, but if the problem was in the sphere itself, or some kind of complex gear train for the roll function, it is best to just exchange the whole unit. Even though I have all the tools for working on these indicators, the investment in time must be considered. As one ADI dies, it may be a simple matter of swapping an amplifier module from the faulty unit. It would provide the spare parts needed to keep these masterpieces of engineering craftsmanship going. You can see the early days of my 747 cockpit at: www.petergottlieb.com/docs/747_Restoration_For_Sim.pdf It does not show the instrument testing, but that has been going on for the past 10 years now. Your work has been a HUGE help to me as you have figured out multiple 747 instruments in the past. That saves me the time of having to reverse-engineer the same indicators you already did in the absolutely fantastic videos you produce. Keep it up!
@@timmiller8600 Hi! Yes, it has evolved since 2012, but the work is not very glamorous. A lot of disassembly of control heads/panels, restoration and rewiring. The 2012 pictures are obviously outdated and different panels now populate the Flight Engineer's station and some different primary flight instruments installed. I don't have any social media accounts, or websites, detailing my progress. I can't possibly do a better job than Michel with his teardowns. Maintaining an on-line presence with updates would take too much time to maintain and I could not handle all of the questions I would get. I retired this year, which has allowed me to spend much more time on the 747 and all the support interfaces it requires.
@@mattwietlispach7606thank you. I understand, you do this for your own satisfaction! Appreciate what you _did_ share already. Good luck and enjoy your awesome creation!
І am an expert in Soviet aircraft instruments and have a big private collection, I am Ukrainian. As well a lot of documentation. We need to create some international community including Michel, but I do not know yet how to do that. Probably the telegram group. Problem is that Soviet instruments contains a lot of precious metals and I do afraid that in such a group could be more metal collectors and instrument destroyers, rather real hobbyists.
@@robertmonroe9728 I think that it was possible to directly cooperate with Michael, to send it to him through international forwarding, such as Novaya Poshta, for review.
I guess I got lucky since the attitude indicators I use only have 4 pins, 28 volts + - for the gyro, and 28 volts either polarity for the internal lighting, it's super small, it's a standby attitude indicator from an S211 trainer jet

Indicators! My favorite! Such pretty instruments.

@mattwietlispach7606 Really enjoyed the file you posted. But, has the work progressed since then? It looks like it's last updated in 2012!

It operates ! I love it ! Out of curiosity, how do you power aircraft equipment in the lab? These are usually designed to operate at 400Hz.
I use the inverter described in videos 323 and 334:

Hello! how can I support your channel? I would like to see more Soviet-style aircraft instruments. Thanks for your work Michael.

I have a similar attitude indicator containing real servo system, but not yet reverse engineered it. It is older and looks more complex than this
