SL-OmniTrack is a my very own telemetry and flight controlling system. It has a avionics bay which gather data's from sensors like IMU , Barometer's , GPS module and save it to SD card and send it to ground station module wirelessly via LoRa transceiver. Ground station just receives those data and send it to connected laptop via USB cable and i will also make a software under another project. That software will receive those data and do useful things like running sensor fusion algorithms like Extended Kalman Filter (EFK) and accurate GPS position to form a highly accurate visualization of rocket even in real-time. Software will also show usefull graphs in real-time like "alt-time" , "velo-time" etc. Later for TVC rocket i will add sensor fusion and steering login in avionics bay itself but in version 1 its only for data gathering.

Sl-OmniTrack V1

Today i started working on MVP of this project which is V1, plan for power cirucuit was to use one 18650 battery with MT6508 (not sure about module name hehe) to boost the 3.6v from battery to stable 5v for ESP32-S3, but boost module had some problem.
Intial decision to use one battery was due to weight but v1 isnt gonna fly so i used diff plan.
I used 2 batteries with a working buck converter to step down 7.4v to 5v.
I also tested my MPU9250 one last time with a diff MCU just to make sure before labelling it as corrected MPU6500

Devlog #3

What i did -

Mapped out exact pin layouts of most of the component so i can easily make wiring diagram later
Planned power circuit for avionics bay

Devlog #2

What i did -

Coded main.cpp to collect every data possible from MPU9250
Created a test.cpp which can be used to test physical wiring , connection , component’s health for every sensors include MCU of this project all from a single code
Added toggle code so i can toggle on/off which sensors to test

Constraints -

During using my test code, it found that my MPU9250 doesnt have magnomete so basically i got ripped off by seller and its just a MPU6500🥲

Next Goal -

See if i can get some more fund so i can buy original MPU9250
Refine my test code more so i can use it in future for other project too since its working great and found reality of my IMU
Complete my main.cpp to collect data from EVERY sensors instead of just IMU

This might get long…. I was working on this project since 20th June but was on macondo event, so here is whole devlog from start to end of untill now.
I started with learning about sensor fusing algos. Then learned about Euler angles but found they have cons like gimbal lock so decided on using quanterions. Even after these i have worked so much but couldn’t log them. Also you can use my github commit history.
