    Tilt Sensors for axis movements

    Has anyone looked at using tilt sensors for axis movements such as yokes.

    Dual axis sensors are fairly cheap and one could be mounted in the yoke, thus providing X, Y, and Z input. I guess the issue would be communicating it to FSUIPC or windows.

    The benefit would be the ease of installation and interface.

    Hi Warren,

    Can you put a link to what these look like?

    Thanks

    Re: Tilt Sensors for axis movements

    Here are a few that I found. There are a ton out there, at different price levels.

    These are found in a lot of the newer cell phones (iphone and some that run android) and are the brains behind the bubble level apps and gamepads.

    Here's a link to something available at digikey:

    These are small enough to mount inside the actual yoke handle, I would think. If it was dual axis, that would be all you need.

    Re: Tilt Sensors for axis movements

    Wouldn't you need 2 single axis? One to read the shaft movement (pitch) and another mounter in the yoke for roll? Or could you position one on its side in the yoke and get both axis? Just thinking that the off axis reading is +/-45 on these so initial positioning might be critical (mounting vertical might already exceed available reading). Interesting idea!

    Re: Tilt Sensors for axis movements

    You will find that most of the sensors are noisy and need correction for drift.

    Also it is not trivial [and sometimes impossible] to separate forces caused by acceleration from those caused by gravity.
    To have good performance you might need to use directional gyros as well.

    If you look at the link he posted it clearly says, integrated signal conditioning and high precision. Your statement is totally incorrect. This option does need some more research! They even have an analog out version. Nice find!

    I apologise, of course you are right. This is the best solution for yoke movement sensing that I have ever seen.

    This one would work perfect,

    Notice the .02deg stability, much better than my Saitek yoke!!!!!! LOL

    Have you noticed cross-axis coupling of 3%?
    90 degrees input of roll axis can produce up to 3 degrees contamination input to pitch axis.
    Now compare 0.02 deg stability and 3 deg error. I suggest keeping your Saitek at least for now. LOL

    LOL, I think you picked the wrong guy to go after for his electronics knowledge
