movement tracking gimbal

Community Projects

Hi.

New to the forum and to the world of arduino and sparkfun.

I will start by admitting that I only have basic knowledge of electronics but want to learn and while doing the step by step arduino projects they are leading to a project I want to try.

I am sure there are similar projects out there and it would be nice to hear about them.

What I am looking to do is use accelerometer and gyro controlled RX. As it is now I use fatshark headtracking input into the trainer port of my spectrum DX8 controller but the reaction and precision of the HT isn’t good enough for me.

Before I commit to this project I want to know:

1: Using Arduino Mega 2560 R3 and the 9 Degrees of Freedom - Razor IMU can i count on precision good enough to give input to a gimbal (via RX) and not get any lag compared to regular stick input?

2: Is the combo I chose good enough for the project?

3: Should I build the unit in to an RX instead of utilizing the trainer port?

And ofcourse 4: Is this the right place for this query or does it belong somewhere else.

Thank you :slight_smile:

I don’t have any experience with Fatshark or the DX8, I just have a DX5… Anyway, my point is, maybe the reason why it’s slow is the hardware it has now. You need to check, because maybe the Arduino may be slower… Or the communication protocol is slow, which it could be set at it’s fastest without losing packets…

Something to think about…

Thanks, will look at that. Anyone know what the Latency would be from arduino to potentiometer? If that is fast enough I could easily connect the arduino straight to the dx8’s potentiometers.
