  1. lua export This is an interesting approach to the problem. What I, and I think others, have been doing is basically the opposite: automatically send all physical switch positions to the sim at mission start, and solve the problem that way. Your way will work too, though. Might even be more fun. Cheers, Colin
  2. Oh wait, it's 2-conductor; I didn't see that. And maybe extra heavy insulation. 22 ga should be a OK. No smaller than 24. Looks like it's solid wire so that's a good thing for connections on the same panel. You *could* daisy chain the grounds but with Leo's board having a ground per input, I'd be tempted to do it just the way you did it. Cheers, Colin
  3. Hey Pitbldr, what are you using for wire? Looks like you took it out of your wall :-) Cheers, Colin
  4. Very nice indeed. Colin
  5. Ususally we make the switches in the sim mimic the switches in the physical pit; and we make the dispalys in the physical pit mimic those in the sim. So if we can stretch the definition of "display" to include backlighting we use the brightness in the sim to set the brightness in the phys pit. But I don't know if we can extract that value. One other thing: we don't need to vary the voltage to vary the brightness of the LEDs; we can use pwm.
  6. So here is the working panel with pitbldr's light plate and my electronics. I've only populated one of the Fill Disable switches while I figure out what to do about them. Fuel-front.bmp And the back. Normally I would attach the circuit board to the switch plate. But this time I extended the 4 through bolts with standoffs to support a little platform, and attached the PCB to it. Fuel-back.bmp And some side detail: Fuel-side.bmp And finally a hurried video showing TCP output: Thanks for looking, Colin
  7. The calculation (and the many calculators) give you the minimum value, say 150 r or so. Of course a lot of us just use 470 out of habit or convention or something. Every Microchip development board I have ever seen uses 470 for the 5 V red LEDs. But try this. Hook up the LED with 470, then 330, then 220. Just to see if there's any difference in the brightness. Cheers, Colin
  8. This is good: http://sound.westhost.com/pots.htm And here is more detail than you would probably ever want: http://www.bourns.com/bu/bu02_17intro.html Enjoy, Colin
  9. Just look for "dual pot". Not "dual shaft pot". Cheers, Colin
  10. Yes. It's called "Potentiometer With Switch". Sometimes just "pot w/switch". No trouble, really. Happy to help. Cheers, Colin
  11. The standards don't call for acrylic however. I would leave it at 3mm, 1/8", whatever. Acrylic might be too flimsy at 1/16". One material that might work at that thickness is FR4 circuit board. Aluminum would probably be easier to work though. Cheers, Colin
  12. If you're not already losing sleep over this, maybe I can fix that :-) Consider also that when the power is turned off in the sim, you want the lights to go off in your pit. Just here to help :-) Colin
  13. Very nice.
  14. Thanks for the interest. These boards have 16 inputs. Any of the inputs can be: Momentary switch Toggle switch 3-way switch Rotary switch 2-bit incremental encoder 4-bit binary of Gray encoder Three of the inputs can be pots. One nice thing is that with multiple input devices, the inputs can be attached in any order. They don't need to be consecutive or even contiguous. I have one of these running the Fuel System control panel. I'll make a short movie with pitbldr's front plate and my circuit board. These are the Rev 1 boards. I just got the first batch of Rev 2 boards back from the board house yesterday. Rev 2 uses a newer processor. Only obvious difference is that now 6 of the inputs can be pots. Feel free to ask any questions. Thanks, Colin
  15. It is possible to use pot inputs to control those types of knobs through lua. It is not possible to assign an axis to these knobs. We have been through this. Cheers, Colin
  16. Switches are just electro-mechanical devices, but when you start asking about LEDs and resistors you are entering the realm of basic electronics, starting with Ohm's law and moving on from there. This is probably not the place to go for that education. Cheers, Colin
  17. Why would you do this? Just curious, Colin
  18. Here is a rotary switch: Here is a pot: The other thing that's very confusing is some people say rotary switch when they mean encoder. Then there's the two completley different meaning of the term "rotary engine". Just kidding; that's a little bit off topic :-) Cheers, Colin
  19. Sorry, all I meant was: which is the analogue of which? To me,a slider in a computer program works kind of like a pot in the real world :-) Colin
  20. TS, there's somthing funny about this statement, don't ya think? Colin
  21. See slide 7 in the link in this topic: http://forums.eagle.ru/showthread.php?t=73855

  23. For a 3-position switch in the sim you just need a SPDT center off, On-Off-On like TS said. Both the SPDT On-On and the SPDT On-Off-On have three terminals; the centre one goes to ground. The SPST Off-On just has two terminals; either one goes to ground. You can also get Off-(On), (On)-Off-(On), and On-Off-(On) Same as Off-Mom, Mom-Off-Mom, and On-Off-Mom Momentary is spring return.
