Hiya all,

Anyone got any suggestions/links for an electronics novice regarding building button bays.
Anyone build a controller based on this http://www.lbodnar.dsl.pipex.com/joystick/index.html ?
Does the game support 8 analogue inputs + 32 buttons on one controller?<div class="ev_tpc_signature">

I'm pretty good fitted with my CH HOTAS, but especially for LOMAC and Falcon4:AF, you just can have enough buttons. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

So I'm primarily planning an additional panel with buttons and switches. The additional analogue inputs probably will end up in a rudder and seperate thrust controls for LOMAC. Those will be added later on.<div class="ev_tpc_signature">

I've built a button bay with one of Leo's joystick controllers and cannot imagine flying without it now. There's a lot of info on the process on this thread: http://forums.ubi.com/eve/forums?a=tpc&f=26310365&m=9831081034

And this is a picture of what I ended up with: http://i10.photobucket.com/albums/a109/johnfsknight/LED.jpg

Best of luck with this - get a decent soldering iron!

PS BTW: I think Il-2 is limited to four controllers in total, but there is no limit AFAIK to the number of switches and pot inputs. My version has the full 32 switches and uses 4 rotary controllers for trim and prop pitch. It sits alongside a full CH set up, so God knows how many buttons in total... http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

I had something similar in mind. In my old room under a roof, I planned to build a flat pannel attached to the sloped ceiling above my seat. Now I moved, I decided to build a frame around my TFT, where the buttons and levers will be positioned.<div class="ev_tpc_signature">

Here's my project so far. I started with a desktop cockpit but it has now turned into a simpit. It uses the Bodnar controller and it's excellent stuff. Very easy to use...

Padser: I have seen your button bay before. It is indeed impressive.

But I wanted to ask you about your choice of switches. They appear to be toggle switches, that if I am correct will either send no signal, or a signal after the switch is thrown.

Is it not correct that after the switch is thrown, will it not keep sending that signal until the switch is returned to the open position?

So in other words for example while the hook up, (or any of them for that matter) switch it thrown, is it not CONTINUALLY in effect pressing whatever key combination is set for hook up?

Would not spring loaded buttons that only send a signal while the button are being depressed have been better? Would not these spring loaded buttons be more like keyboard buttons, in that they will only send a signal while pressed? Thus avoiding some strange key combinations from inadvertently being sent.

I am planning something very similar which is why I ask. Thanks.<div class="ev_tpc_signature">

Thats very nice padser, pretty much what I had in mind.

On a related question whats the status of devicelink and online play, I searched through old posts and found one that says these parameters work online, is that it? Can anyone confirm this?

~S~

I used a combination - some locking, some not - but all of them are ON-OFF-ON switches (either giving you a separate joystick button at either end of the throw, or the same button at either end, depending upon how you wire them up).

I tried to use locking switches (i.e., they stay in the ON position when thrown) where it seemed appropriate to the intended control. E.g., gear, hook, flaps, lights, etc.) as this gives me a degree of visual feedback on the control state. To assist in this feedback I also wired in some LEDs to highlight gear and hook status. Maybe I need to get out more, but it still gives me a blast seeing my gear warning light behaving in the same way as the one in my virtual cockpit... http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

With these switches, the 'joystick button' does indeed remain pressed and continues to send its signal to the controller. However, this doesn't seem to matter and has caused me no difficulties whatsoever. I like the feel of throwing a switch and feeling it snap into position - it works and feels like the switches in the little microlight I fly when I'm not flying my computer. Just my preference, I guess.

In other cases, I've used spring-loaded 'push to make' switches of the type you describe - i.e., I push the switch to the ON position and then release it (back to OFF). Were you to use these switches for all of your controls, you would not need to use diodes in your wiring circuits. If you use locking switches, the diodes are essential, otherwise, as you rightly suggest, having multiple (I think more than four) switches on at once would create unwanted row and column combinations in the controller switch matrix and result in extraneous inputs.

These are the switches I used - if you look at the specifications, you'll see that they are types B [ON-OFF-ON locking both ways, centre off] and H [(ON)-OFF-(ON) non-locking both ways, centre off]: http://www.maplin.co.uk/module.aspx?ModuleNo=2341&doy=15m11

Good luck with the project and stay in touch - I'd be happy to help if I can.

PS Have you seen these - I aim to use one as a weapon arming switch in my next controller... (like I said, about getting out more... http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif)

Well I think you have a life! I too like the weapon arming switch, can't hit it by accident. I totally believe you that constantly sending a signal causes you know trouble. (There is a switch on the x-45 that acts like that... so I believe. Still not keen on it, and I would like to avoid it, but I understand and agree with your opinion on liking to be able to see what is thrown or not. Also like the lights corresponding with the throw, very cool!<div class="ev_tpc_signature">

~S~ Waldo

There is another way of doing this, though it requires greater knowledge of circuits than I have to understand it...

The posting you want to read is by 'chuckrc', a little way down this thread over at (Shhh!) Simviation... http://www.simviation.com/cgi-bin/yabb/YaBB.cgi?board=h...splay;num=1145609154 (http://www.simviation.com/cgi-bin/yabb/YaBB.cgi?board=homebuild;action=display;num=114560 9154)

This method will apparently allow a single throw switch (ON-OFF) to send a momentary signal each time it is thrown - it sounds great and would be perfect for toggling controls in IL-2, I just don't understand how to do it... http://forums.ubi.com/images/smilies/blink.gif Doh!

I dont understand it either really, but from reading a website or two...
... when the switch is closed the relay will be held on for a short time (while the capacitor charges) and then opened again (once the capacitor is fully charged) thus resulting in the left hand circuit being made for a short time.
My question is what happens when the switch is opened? does the capacitor discharge causing the relay to be closed again???? If so this is super, and exactlt whats needed for a toggle switch to in game toggle function, I have seen a really nice looking toggle switch with an LED in the end which is switched on when the switch is on.. http://www.maplin.co.uk/Module.aspx?ModuleNo=43005&crit...20SWITCHES&doy=16m11 (http://www.maplin.co.uk/Module.aspx?ModuleNo=43005&criteria=TOGGLE%20SWITCHES&doy=16m11)
All this doesnt solve the problem of synchronisation at game start.
I wonder if it would be possible to drive multiple similar circuits as this off the single +5 volt connector on the USB controller thingy?

Its gonna be a right forest of wires in there, I wonder if theres a neater way... I remember a kind of white gridded board that you can stick component pins into a sort of quick and dirty circuit board, is there a more proffesional and durable version of this that could be utilised.

Gosh all this would be so much simpler if I had paid attention at school all those years ago. http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif<div class="ev_tpc_signature">

While we've got this thread up and running, I'm intrigued by your long shaft joystick, Vanderstock.

I've recently built one of these, too, and am very pleased with the results. I used a gearing system to increase the throw of the potentiometers - do you use something similar, or does the calibration software allow you to compensate adequately for the relatively small movement a longer stick allows?

For example, my CH Fighter stick has a throw of around 30 degrees from vertical in each direction. My long stick, which is around 50cm from high hat to pivot point, would only rotate around 10 degrees for a similar amount of lateral movement. My gears convert this to about 40 degrees (4 in 1 ratio).

I'm currently working on the next generation of my prototype and am again looking into using gears although would prefer to avoid it if at all possible as it looks like I will have to engineer them this time. Anyone have any experience of beta innovations and their X-AMP Small signal amplifier (http://www.betainnovations.com/)?

Cheers,
