Is my idea of basecam usage on a motorbike possible?
  • spamplemousse
    Hello,

    I discovered the basecam world recently, so I don't yet really know what's possible with, how to work with, etc... And as I have a little bit different usage than with a drone, I have some questions... (I also don't know the right terms, and english isn't my mother tongue, so sorry if my message isn't crystal clear ;))

    But first let me explain what I'd like to do. Instead of using gimbal under a drone, I'd like to use it on my motorbike (on top of the handlebar), to keep a stable horizon while motorbike is tilting. So I don't need 3 axis, but one or two:
    - Roll is definitely necessary, but I'd like to be able to deactivate it to go back to "classic mode" with camera tilting with the bike
    - Pitch ... I don't know yet
    - Yaw isn't necessary in my case.

    So I'd like to use a SimpleBGC card, and 3d print a case for the card and motors. But I'd like to have possibility to lock an axis at 0°. The idea would be to have 2 switches (one for Roll, one for Pitch) to:
    - or have the axis moving to stay horizontal while bike is on tilt
    - or lock the axis at 0° to let the camera follow motorbike movement (as if there wasn't any gimbal - but on one axis only)

    Is that possible? Is there inputs on SimpleBGC cards to plug switches, and is this function existing on firmware?

    Thanks!

    I am not sure I follow what you are saying, but pretty sure you want all axis working. You can set the follow functionality separate to each axis on the user interface.

    Hello,
    No, I don't need Yaw axis, and for Roll and Pitch I'd like to be able to activate or deactivate them independently. But when I say "deactivate" it means stable at 0°, no move at all (like no gimbal on this axis)
    And I want to activate/deactivate using a switch for each axis.

    Two axis gimbal works ok, but it needs to be 2 axis. There is now SW lock for the motors, but if it is ok gimbal follow works well.

    Why does it need to be 2 axis? For a drone I understand, but my goal is to keep horizon stable when my bike is on tilt. So roll axis should be enough I think. I'd like to test with pitch too, but I'm not sure it will have a better render than without it (that will compensate acceleration and breaking, not sure it will be better than without). That's why I want to build a 2 axis gimbal and looking for a way to lock one axis independently of the other (pitch if I don't like the effect, roll if i want to have image tilting with bike).

    Or said differently, with the same hardware, without having to change nothing else than a switch position, I'd like to still be able to record this kind of movie:

    but with also this kind:

    Build a very strong 3 axis gimbal and look into the follow functionality. Or build just 2 axis gimbal. It still needs to be strong to withstand the external loads. Also you will need vibration dampening. And you can build also 1 axis gimbal.

    What is not possible is 3 Axis gimbal with SW lock for the axis, but you can have different 1 or 2 axis profiles and mechanically lock the unused axis.

  • spamplemousse
    If I understood well what follow mode is, that's not what I need.
    And a mechanical lock was my first idea, but I don't like it. If I forgot to remove the "mechanical lock", I think motors will burn... That why I would prefer a "motor lock".
    And why that's not possible to do that with a switch? Because there's no input on the card, or of the software? (I don't see any other reason)

    Because it is not how it works. You can use very tight follow settings, that is the best SW "lock" you will get.
