  • @Robert: Perhaps, but a flux capacitor would only be good for going back 10 seconds before you crash. Jokes aside, Ellison, any ideas for a tempro spacial projector?

  • Gareth, I was going to put it in the "hacks" wiki page.

  • Ok Gareth, now please tell me all this sub-space talk is a joke.

    Maybe we just need to use some flux capacitors to stabilize the mount?

    Jim, so you're saying that that mount system doesn't work for units with accelerometers, only with gyros?  That's interesting. As I said I tried a super soft mount and found the wires pulled it all over the places (a number of my cables are shielded/jacketed and stiff).   I wonder then what is the ideal for us?  Maybe the heli gyro system where they have a layer of gel, a metal plate, more gel, then the sensor.  The plate in the middle absorbs much of the vibration.

  • @Ellison, An inertial dampener wouldnt work too well. It would have to be very specific.Dampening or removing inertia from the equation would remove the apms ability to sense where it is. With regards to putting the board in a sub space bubble. That would cause interesting effects relative to time compression with the rest of the copter. Perhaps a 3 space (temporally unpolarised) bubble around the entire copter would work better. Then again, propellers that move air wouldnt function in a temporally de-coupled environment. Perhaps a form of subspace projector would work better for movement. As far as navigation or spacial orientation in an "out of phase" environment goes... I'll have to ponder more on that... Direct vectors would work

  • Hey Max, do you mind if I add your mounting method to the AC wiki?

  • no, that adds way too much mass to the autopilot, it needs to be able to follow the movement of the frame

  • 3692342667?profile=originalSomething like this.

  • So my impression is that an ideal mount would be something along the lines of: four LIPOs mounted at the ends of a rigid cross for a large moment arm, with the PCB at the center, attached to the rest of the frame by tight rubber bands which have a bounded position (can't slip)?

  • This a similar idea to the FeiYu Tech suspension mount.  That was fine for their gyro only FY20A because the vibrations are less of an issue for those sensors, but it gave problems to many who used it on their modules that used accelerometers to self-level such as the FY-90Q and FY-91Q.  They never should have provided that o-ring mount for those modules!  Those problems were a result of the mount not being able to maintain a level platform for the board,  Every hard-landing changed the level.  Only a degree out of level makes a difference in multicopter performance and when that is always changing you get the Toilet Bowl Effect(TBE), oscillations, etc. The o-rings change with temperature and rot with aging.  I agree with Robert above on the separate IMU.  Isolating the IMU and tuning the weight to isolate or change the harmonic vibrations that negatively affect the sensors is key to optimal performance in multicopters.  Having a Vreg that changes temperature next to these sensors also can cause poor performance.

  • @Ellison: see, now I don't know if you're joking again, or if I'm just way under-educated.   {:o
