1:05 The rocket knows where it is by knowing where it isn't

Awesome work!

nice one

I know that feeling of having to print SEVERAL TIMES the same thing

Nice work!

banger

This is very interesting. But could you do something about the audio? It sounds like you are far away from the microphone

I just came here from the rocketry discord. Great work!

Hey I'm a high school student too doing kinda the same thing I'm working on my first pcb using mainly breakout boards but i was wonder how did you do your voltage regulation circuitry and how many volts and amps it can handle. In my designs i am trying to use a smd switching regulator to handle higher current and volts but i was just wondering what you have done with yours.

This is sick! Awesome work Garrett, keep it up!!

yooo this is super cool, good stuff

These keep getting better lessgooo

Nice!

nice job!

That's cool

I just wanted to say that you did an excellent job of explaining quaternions. It was one of the better concise explanations I've heard to date. You gave an understandable explanation without watering it down to the point of falsehood. It's not an easy needle to thread. Well done!

Hey, good work, man! As I can see, all available fusion algorithms on BNO055 use accelerometer. Is it possible to configure ACC gain for sensor fusion? I don't think that ACC should be used for the TVC rocket since the rocket is flying, and the ACC does not provide any usable data for orientation. That could be your problem with the rocket if you didn't account for it. Unfortunately, it's hard to tell or test how exactly the sensor fusion will work in the case of a rocket. The product flyer claims it could be used for drones (and so, probably rockets, too), but at the same time, its sensor fusion offers only a 100Hz data rate, which is very low for a drone. Alternatively, you can easily write an orientation estimator based purely on gyro data + quaternions (no EKF needed), which works very well.

yoo I was wondering how to orient something upright, and this has exactly the information I need! I dream of building a rocket league car in real life, that can fly as well, but I'm sure it's a lot tougher than I imagine. If possible could you please list some things that might be important for me to learn during this project? Thanks!

Very good video bravo😊

HELP, I still don't get quaternions

AP as in "advanced placement"...? Is this something you did in high school?? If so, I'm absolutely blown away by this. This paper deals with content typically not taught until the 2nd/3rd year of engineering programs. Hell, I'm impressed by the fact that you even know how to use LaTeX in high school. Moreover, I took a look at the TeX file, you're not just using LaTeX, you're using it at an intermediate/high level too. Even by undergraduate standards, this is impressive. I wish I would've had your maturity and drive when I was your age. Incredible work! If my assumption that this was work you did in high school is correct, I have a question: Where did you find the time to learn everything you needed to do this? e.g. the physics, the math, the typesetting, etc.

"Hi, my name is Garrett, and I'm building a rocket controlled by imaginary numbers" That tells me everything I need to know. *subscribe*

7:45 yeah, could definitely use some kind of Kalman filter - altitude should not be jumping by 200 meters in a fraction of a second. If this is due to the pullups issue you mentioned in another video where you were gonna go with a software workaround, it might be worth scratching off the traces somewhere and adding actual pullups instead. The baro is physically shielded right? Cotton wool etc.

even a random kid on youtube is hiding his Intellectual Property lol

why is bro lowk majestic...

Acapella Science did a _Hamilton_ parody for William Rowan Hamilton, the inventor of quaternions. In it there's a line: "...and no one uses my quaternions, but just you wait, just you wait!" It's a real banger, y'all should look it up.

Go the next step and use Clifford Algebra and Geometric Calculus.

Garret.......is that the TVC system from BPS Space ? Or your own

1:27 an extended WHAT filter?

Good effort 👍🏼

Nice video. well done

gosh you'e cute

What an interesting name for the flight computer! Very unique lol

This is honestly really cool and I wish you luck. But it's so stupid you can't talk about math or Uncle Sam will get angry.

Awesome work!

A gyro from RC hobby to trigger the chute.

awesome project and pretty sweet editing. it may be worth it to test the gimble and the parameters with a pressure washer nozzle instead of rocket motor in a semi-static test stand. mount the rocket by its centre of rotation on a swivel and you get infinite flight time. possibly being able to adjust the PID values mid test. best of luck🚀

3:53 multiplying a quaternion the conjugate of it gets the real part i think, did you mean multiplicative inverse?

What you are using as rocket body ??

Loved the failure analysis. If you are looking for better servos I’d recommend the JX CLS6336HV. They’re a bit heavier than what you have but they are super fast.

I salute the humility🫡 awesome content man. Kept me retained the whole time🔥 Keep going!

4:34 The Wii melody saved it! 😇

I wanna talk to you about these things so could you help me plz ?

Great job bruv

Appreciate your work, keep going!

Keep going mate I liked this video so im subbed

I guess I'll follow this channel for the upcommin years now

Hi dude i m a sophomore electrical engineer, who wants to focus on control engineering, i had a conversation with a former gnc engineer. And he told me to study some group theory to understand quarternions. I didn't know what either of these things were. While being overwhelmed by heavy math. I found you bro. Thanks

Gotta love quarternions in control systems

THIS IS SICK
