Hello guys, Long time no see! This post is to ask if there is still a desire for this product. I still get an e-mail a few times a year asking if I still produce and sell these boards. I just now made a forum search for the B256A13 and I must say that I am touched by the posts speaking well of it in the last 8 years or so that I have been out of the market. Someone guessed that I may have left the hobby. That has never been the case even though I spend some less time with it now. I work with real fighter simulators nowadays but I still love it enough to have it as a hobby as well. The real reason behind the disappearance of this product is I got an offer for the design of the B256A13 so I sold an exclusive license to use the design for commercial purposes meaning I am not allowed to sell these boards any more. I got this offer in a time when I was also quite tired of soldering these boards by hand during the evenings and weekends, even though I loved helping the community with a product that was needed. I received so much gratitude and love from my customers and that was an amazing feeling. Believe me, every request I have received since then I have been like "Aaw, I wish I could just make him a board" because as I understand there are still no alternatives available with similar specifications. I miss the electronics hobby now and so I am thinking about making a new but similar design. However this time I would have them assembled by machine and so would require larger production batches than before to make it feasible. This new design would feature the encoder support that the B256A13 lacked. I am thinking about a price tag of 900 SEK for an assembled and tested board. Probably no DIY kits this time because packing these was quite time consuming as well. If you are interested drop me a PM or an e-mail (farbror_brydling@hotmail.com), or just give a shout here. If I receive enough interest I may launch a Kickstarter and get this going. I would also happily receive some constructive critizism about the previous design. Personally I think that this design of button matrix was superior in that it allowed wiring up a panel with a lot fewer cables than for example a BU0836X. You could wire up a 16 input panel using just 8 wires or a 25 input panel using just 10 wires instead of having at one wire for every input + GND as on the 0836X. The drawback being you need to put diodes in the panels and it is a bit harder to understand if you're not into electronics. Does this scare some of you off? Would you rather have the diodes mounted on the board making this matrix connection technique to the panels impossible thus requiring more wires but a bit more straightforward connection?

I hope it will come of use to you :) If something is missing feel free to add it to the code and send me a pull request. There are probably lots of features to wish for.

Projects are up on GitHub now and the original post is edited. Feel free to contribute :)

No problem. I'm glad if it can be of use for more people. I've just migrated all my SVN repositories to Git, so I'm thinking about putting this up on Bitbucket/GitHub so that others can contribute. Regards Niclas

Updated to new versions in the original post: -Fixed a bug on Windows XP where local_supervisor would not detect if the processes are manually started by the user -Removed separate buttons for Start and Stop in Supervisor. Now you just click in the big red/green field. Made it this way because it looks better on touch-screens. -Removed the window frame in Supervisor. To move the window, click and drag where there are no elements. In the gray area between the buttons/labels. To close the window, use Alt+F4. -Made it so that Supervisor remembers where the window was last time, and opens it in the same position on the desktop.

That's great news! :) By changing the position of the wires you can move both the zero position and the rotation direction. Many indicators don't actually have the electrical zero at the visual zero position, so an offset will always be needed in software for these. But in Helios it is possible to make whatever mathematical manipulation of the values you want by using Lua if I have understood correctly?

Is this still available? :)

I see that you have been told otherwise, so I just want to clarify. Higher resistance does NOT give better accuracy. It gives more electric noise however, giving poorer accuracy. I would recommend 1k, not more. They are the same price. Edit: Just to clarify some more. You probably won't notice much difference between 1k and 10k, so if you already have some pots with resistance >1k you can use them without a problem. When buying new ones however, there is no reason to buy ones with a resistance larger than 1k. If you notice problems with unstable values from your >1k potentiometers you can try changing them to 1k. Long cables and a noisy environment will make them more susceptible to noise.

Ok. Just give me a shout if you want any help when you have the necessary equipment :)

The ADI should be straightforward as you say :-) What I think you should worry most about is the standby attitude indicator. Why is there a synchro and a resolver for each axis? I think that is very odd since a synchro and a resolver is basically the same thing with a different number of phases. Don't you mean a synchro and a 2-phase AC-motor?

That sounds odd. If you can get your hands on some technical documentation or open them and take some photos of the components inside I'm sure we can figure out how to bring them to life :)

Simulator intstruments are perfect, then you have a good chance it will work without too much struggle. Do you know if they have electronics built-in or do they just consist of a synchro control transformer and an AC-motor for each axis? If the inverters are too expensive I'm sure you can build your own on a breadboard. I don't think there are many parts involved.

Are you sure they can be controlled by just a synchro transmitter or a DTS-board? I think that you may need special amplifier boards as well. The ADI in the A-10C and the AJ37 have these amplifier circuits built-in, so your primary ADI might have them too. Your HSI may also have them internally if you're lucky, the one in the A-10C does. Your standby attitude indicator will most probably not have them however. Is it a SAI from a simulator? If it is a real one it probably has it's own gyro and doesn't use synchros at all. If you have the part designations then maybe it is possible to find a technical manual on the Internet? Powell has some schematics for building your own 400 Hz inverter if I remember correctly. Shouldn't be too hard, just an oscillator and a pair of audio amplifiers in push-pull configuration to get up to 26 Vac. You will probably need a 26/115 Vac transformer as well, because the ADI/HSI might need 115 Vac.

Do you have a technical spec for the indicators Gene?

Didn't see this the first time :) It is very superior for it's purposes. It seems I was wrong about "downgrading" though. The TIDLS link seems to be there in parallell with Link16 on the Gripen. They complement each other. TIDLS is being used for stuff like sharing sensor information, for example using several aircraft's radars in passive mode to triangulate targets and other tricks you can use with several radars integrated in real-time. Very much more detailed information than Link16 can share, but it only works with a group of fighters whereas Link16 can be used to communicate with lots and lots of units. Edit: - http://aviationweek.com/awin/saab-takes-next-step-fighter-development Sweden has been VERY early with data links and exploiting the possibilities they give.

The ES-05 Raven radar chosen for Gripen E/F is made by Selex. The older PS-05 is made by Ericsson in cooperation with some other party that I don't remember.

Quoting this again, because I realize I forgot to reply to the link. Again with the intention of making a fool out of someone instead of using arguments, but I am going to ignore that for now. What was the fun part anyway? Larger hydraulics systems enables faster control surfaces. Gripen's comparatively small and cheaper hydraulics system was the root of this problem, and the US had never had to handle a case like that because they just throw bigger hardware at the problems (not saying it's a bad thing, just expensive). The control surfaces in for example the F-16 move fast enough to not be subjected by this issue. Haha, finally it came to good use! ;) Yes, I did confuse them. I knew the US also had an aircraft at the same time that they experienced difficulties with now that I read it, hence the cooperation. But if I remember correctly their problems was caused by something else. I believe they had a powerful enough hydraulics system to have control surfaces that doesn't lag behind the pilot input.

I don't think that I do. Not with the intention of making a fool out of someone. Just with the intention of being able to clearly reply to just one bit of a post. The intent of that post was to make it look like I say that I had proof when I didn't, and make it look like I demand proof from others even though I can't prove things myself. Totally different from what I am doing when quoting only one fragment of a post. Now, bring the discussion up one step.

This specific patent is owned by Saab.

This is the solution I have heard about. Didn't know the details existed on the Internet. That is also the patent that I was referring to. Saab came up with this solution.

I agree :)

Ah, ok. Actually I think almost the whole aircraft is designed in Sweden, if you look at size of the parts involved. The airframe, all the major physical systems, the main part of the avionics and software for it. The only big thing designed outside Sweden is the engine. Then it is various sensors and weapons and some other small stuff. Important stuff of course, but no-one can claim that most of the aircraft is not Swedish.

Too long to read to get answer to a simple question. I still don't understand how the US could prevent Sweden from exporting their own software. Still, it doesn't matter since some of the hardware is American anyway.

There is no need to be rude about it. I think I keep a pretty mature level in this discussion. It is a fact that I have heard these things. I think it is a perfectly correct formulation. Again, the maturity level of your language.. No, I do not know exactly how export restrictions work. Can you explain how America could put export restrictions on software that they do not own?
