You're welcome when you're ready! :) And my response is a month late ;)

I forgot about this thread. The programs have been updated several times. I think they were quite useless in their original form. I have added the latest versions to the first post. They work better now.

Thank you for your feedback! :) Good luck with your project!

Powell's design does not work in it's original form, however he has made a correction but I don't know where to find the updated schematics. I don't know where to find the original schematics either, only the layout :P

Hi 3dpilot! I really need to subscribe to my own threads so I get an update when someone makes a post :) Since we have spoken over PM I guess no harm was done this time :)

12 bits or 0.088 degrees per step.

Did some test flying with FSX today using a fake synchro instrument showing heading. I used SIOC and FSUIPC. It worked really well! :)

Haha ;-) It will take two boards since it doesn't have a heading axis. The cost is just an indication, I haven't calculated exact material costs yet and I don't know how much time it will take to assemble and test a board. It may be cheaper, but my gut feeling is that it won't.

Yeah, but it all depends on how dedicated you are. Imagine what we will spend on driving all the synchro instruments in our simulators then ;)

Interfacing with Helios will be up to Gadroc I guess :-) I will develop a program that speaks IOCP, for integration with SIOC.

Nice to see so much interest aside from the ones I already knew needed this! Maybe I should add some info about the price before everyone gets super excited, because it will be a little pricey! Info added to first post.

I have built the second prototype of my digital-to-synchro board and tested it with good results. I am about to design the final solution and order real PCB's. Will probably have something to sell in april or slightly before. It will require a separate 400 Hz power supply. Just wanted to tell because I know some of you are sitting on real instruments that need to be interfaced! Edit: The price will be about 800-900 SEK for one board. You will need one board for every synchro output, so for a 3-axis ADI you will need three boards. Also, this board only generates the three stator outputs from a synchro. That is not enough to control all synchro-based instruments. The ones with a synchro receiver/repeater that directly drives a needle will be fine with only this board. Instruments that just have the synchro as a position sensor that controls an AC-motor will need an extra amplifier. Some instruments have these amplifiers internally (the ARU-2B/A ADI for example) and will also be controllable with this board without any extra electronics (400 Hz supply needed of course). If you are unsure, get yourself a synchro transmitter or receiver/repeater. If you can control the instrument using only this synchro and a 400 Hz power supply, this board will be able to do it. Amplifier boards for driving the instruments that need them is my next electronics project. We need it for our standby ADIs in the Draken and Viggen simulators.

Nice work! This looks promising.

I have a lot of time to solder boards the rest of this week and in the beginning of the next one, so to all of you that are thinking about ordering one: Make up your mind and do it now for quicker delivery :-) Instructions in this thread. /Niclas

Just want to say that I have a lot of time to solder boards this week and the beginning of next week, so to all of you that are thinking about ordering one: Make up your mind and order now for quicker delivery :-)

You can press all the buttons at the same time. Except for the POV-switches of course, which can only accept the combinations N, N+E, E, S+E, S, S+W, W and N+W.

1020 SEK + shipping (170 SEK in your case) for a total of 1190 SEK. That is for a fully assembled board with eight assembled connectors + 10 cm cable attached to each of them and 200 diodes. Niclas

That is correct. We are working at ordered overtime until christmas as far as we know right now. It could probably be prolonged. On top of that we are refurbishing our apartment and I am in the working of writing a complete model of the avionics and airframe systems of the AJS 37 Viggen. Except for the modeling I also have to create the special electronic interfaces needed to drive the original parts. Sorry for not replying earlier. I read the messages but didn't have time to respond at the moment, and when I had the time I had of course forgot it :-) I have about 15 PCB's left but very little time to make them. Previously when I was overloaded I teached my girlfriend how to solder the boards so that I only needed to do the programming and testing, but she has also got a job now (finally!) so I don't want to force her into doing my interests anymore ;-) You can place an order if you want to. I am still selling them. But it can take 2-3 weeks to get the board done. If you want a DIY-kit it goes a little bit faster but I still need to test all the pins of all the IC's before shipping :-)

Hope you're not giving up? :)

Take a knife and rasp all the way between the first and the second rows on the back of the board. I think you have a bridge there.

Hi Tom! I don't understand which inputs are closed and when? The naming of the boards is a Windows issue. Windows can't successfully read the name of two different interfaces on the same device. It can't even read the name of two identical controllers with different names, it just gives the same name to all of them. I guess it can only save one name for every VID/PID-combination. Best regards, Niclas

Got to give people what they paid for :)

The first post in the thread over at the For Sale section has been updated with info on this bug and instructions for how to update the firmware!

The first post has been updated with info on a new bug and instructions for how to update the firmware!

I will give the same answer here so that others can see. A firmware problem has been detected. The matrix is scanned too fast which can give ghost inputs with longer cables. A new firmware that fixes the issue has been developed, but I don't have an Internet connection at home right now because of broken hardware. As soon as I get the new modem (today or on monday) I will post the new firmware along with update instructions in the official thread (For Sale-section).
