The Bored Engineers
We are two bored engineers 🙂
i have found your library about the osd: https://theboredengineers.com/2012/12/a-max7456-library-for-arduino/
i have a little problem with it:
can you provide me the exact wiring between arduino and max7456 (by sparkfun)?
can i have the code for MAX7456 library and a sample sketch?
Everything's here https://theboredengineers.com/2012/12/a-max7456-library-for-arduino/ 😉
I would like to put an IMU on a non-goto telescope (Meade 2110)
and use the output of the IMU to show on stellarium where the scope is pointed.
Perhaps select object in stellarium and then push or drive the scope with it's
original to the object.
I have IMU working with arduino ---- but can't get good enough angles out of it
and stellarium to use them
Can it be done?
It's fun because we thought about doing this a while ago 😀 The thing is, as you said, the precision of the angles. Honestly, I think that using a cheap regular IMU that we typically use on drones/ Arduino won't make it. If you want to keep youor current IMU and get better angles, I suggest you to look at , which is the most accurate and computing power efficicient algorithm I know. It is fairly simple to implement on Arduino (understanding it is another thing :D). Nevertheless, the amount error dure to the sensors themselves might be too much for guiding a telescope with a long focal length.
So I really think you should give it a shot, because it's a really cool project, and who knows how precise it will be ! 🙂
!6 bit output from each gyro axis
that should get around 0.0055 deg accuracy in azimuth
and much better in elevation (0.0014 deg).
So an IMU can keep a Quadcopter steady enough for video imaging
but can't tell me where a telescope is pointed.
Where can I get some help coding up something like this?
Well there is an Arduino library called Free IMU that implements this algorithm, if I remember well. But if you download the pdf thesis, there is a C implementation of the algorithm at the end, so it's pretty much a matter of copying/pasting to put it on your Arduino (assuming you're using one). You really don't have to use this algorithm though, I'm just giving you an option here 😀
But there are many ways to compute 3D orientation with an IMU, I showed a very simple one here:
Hope you can succeed in this project, it would be really cool ! 🙂
Can you please please please guide me/give me the code to get height from MS5611 GY-63 barometer moduleusing Arduino (Due)?
I will be extremely grateful!
