Phidget where do you get them

[747captian]

where do you guys buy your Phidget slider, Phidget boards and servos. When I check for how much they cost they where 100.00 a piece and I need 4 for my overhead panel for the 747 and I dont know what type I need for the throtel's. I would like to have the auto throtel. what type of servos do you need. I build RC airplanes and I have a 4 servos laying around frome a plane that my friend crashed last year. They still work I ave tested them would they work for the auto throtel.

Why, at the Phidget Pharm of course!

Is the Phidget slider 60mm is what you use to build you trotel quadrent or is ther some other slider that is long like a 70mm slider or is that as big as they come?

[Michael Carter]

I used 100mm Panasonic slide pots for mine.

I don't use Phidgets though. I just posted the link for you.

I am using Leo Bodnar's BU0836 for my throttle and one for my SP-150 autopilot. Inexpensive and work very nicely if I do say so myself. Course that overhead has so much, I can certainly see the need for Phidgets.

Another option: Consider using string pots.
These can be expensive to buy, but can be built fairly inexpensively.

Mike has shared how to do this.

Fs2phidgets & textlcd

--------------------------------------------------------------------------------

Hello, I have installed a textlcd in my aft-overhead functioning as the IRS display.

I cannot figure out how to convert the 0560 (lat. offset in fsx) and the 0568 (lon. offset) for displaying right numbers in degrees on my phidgets textlcd.

Is there anybody who can help me and give me a push in the right direction ?

thanks

André

Andre,
Conversion to degrees is not supported at this time.

Thank you for your reply Alan, I know it is not supported, but can we handle it with fsvariable editor ? I can see the raw value,, but do not understand how to edit it. (recalculate) Maybe it makes sence for you after reading the text below from Enrico ?

here we go....

offset 0560 8
Latitude of aircraft in FS units.
To convert to Degrees:

If your compiler supports long long (64-bit) integers then use such a variable to simply copy this 64-bit value into a double floating point variable and multiply by 90.0/(10001750.0 * 65536.0 * 65536.0).

Otherwise you will have to handle the high 32-bits and the low 32-bits separately, combining them into one double floating point value (say dHi). To do, copy the high part (the 32-bit int at 0564) to one double and the low part (the 32-bit unsigned int at 0560) to another (say dLo). Remember that the low part is only part of a bigger number, so doesn’t have a sign of its own. Divide dLo by (65536.0 * 65536.0) to give it its proper magnitude compared to the high part, then either add it to or subtract it from dHi according to whether dHi is positive or negative. This preserves the integrity of the original positive or negative number. Finally multiply the result by 90.0/10001750.0 to get degrees.

Either way, a negative result is South, positive North.

No, you cannot handle with FSvariable. Is not supported.
Don't know how many different ways I can say this.

Technical document that Enrico forwarded to you is from Peter Dowson's SDK. Peter Dowson is the author, not Enrico.
If you read the acknowledgments in the SDK you will see I am one of the early contributors. I am fully aware of this document and its contents.

Doesn't pmSystems support IRS functionality?
Wouldn't pmSystems work better for you?
