I forgot to mention that PCBWay is hosting its annual design contest at the moment! You can enter your electronics, CAD, or STM32 projects to be judged by a team of engineers. Prizes include cash, coupons, and various DIY electronics. Details: www.pcbway.com/activity/7th-project-design-contest.html
You're really great at striking the balance of technical detail and brevity for RUclips. Also I've got my kalman filter set up the same way! I assume you're doing your filter in the inertial frame, and acceleration is rotated out of body frame first?
Real men convert to perifocal and hate themselves
Thank you so much Joe! Yes exactly, I’m transforming the acceleration to the inertial frame before it goes into the filter.
Finally a video that at least somewhat explains the magical Kalman filter. Love the more technically in-depth stuff, very nice work!
Good job, Jacob ❤🔥! Can't wait to see your next one!
Great IMU choice, integration, and video!
Thank you! I'm loving your content too, and I'm very envious of your telemetry system!
Very nice project. I am really impressed how much knowledge you have in such different fields (math, programming, electronics, aerodynamics etc.). I hope you can successfully finish your model rocket. Best of luck!
Excellent video, thank you for sharing! Excited for your first flight!
Thank you!
Super clear and insightful explanations.
Great work Jacob 🚀
Great job, you are a wizard in the world of rockets, congratulations Jacob 🚀
Ah yes. The missile knows where it is at all times. It knows this because it knows where it isn't, by subtracting where it is, from where it isn't, or where it isn't, from where it is, whichever is greater, it obtains a difference, or deviation.
jk, great video, can't wait for more
I know the ESP32 well. Now it seems I have to learn the STM32 since they are used everywhere.
Learning any new chip in depth is a 1,000+ page of manual pain.
What PCB software did you use to design your PCB? Great video :)
Thanks! I used KiCad for this project
Nice video. One question for AHRS fusion alrogithm. Why did you use Madgwick filter even if you can implement kalman filter for position tracking? One of the most key benefit of using Kalman Filter is fast initial convergence and most commercial SOMs using it for this reason. Of course they put their own recipe filters to cope with the external disturbrance and optimizations.🐱🐒🦄🐅🐹🐘🐪
Very impressive!
great you share your knowledge, thank you! I only watched the IMU part. You seem to you pick your favorite car for the highest indication written on the speedometer, not for the real top speed? 🙂bit resolution typically doesn't matter that much, focus on the noise instead, e.g. 2.8mdps/sqrt(Hz) for the gyro. If you integrate over time, the noise of the time gets as important as the sensor noise (as you mentioned with the external clock signal)
Interesting, thank you!
Amazing video 🎉
BNO055 and BNO085 are better alternatives.
They can make sensor fusion for you as well 😊
BNO055 is 9 axis IMU so you save one component on board
This is awesome!
Hello! What software are you using to desing the 3d models of the rockets ?
Fusion360!
Super cool!
impressive
Sehr gut
Why STM32 instead of ESP32, Teensy or RP2040 ?
I really like the STM32 dev environment, and I have quite a bit of experience with them 👍
@@jacobthornhillbut the best for this project is rp2040
Nice
Ok. I'm not an engineer 😅
We need a file for the three-dimensional design of the rocket

Thank you so much!! More to come…
They don't call it rocket science for no reason!
Weeeeeeeeeeeeee 😁
"model rocket"
Your image is really good, but your sound is shit.
Please change it, and the video will be as nice to watch as BPS's.
Yeah, it might be time for a new microphone…
It's really not that bad. It's not amazing audio, but totally passable. I think before dropping cash on a new mic, you should try running your audio through a gentle de-esser and maybe a subtle EQ and compressor, and I bet that would take the audio a long way for free. Although there is something really pleasurable about recording with a really good mic!
Stl??
