Going from the gear train you have to a stepper you have to keep in mind the power requirements for just the motor in flight and flight time. It goes to my comment on the other video on ' hold ' current ' as you want it to hold position as well as change position. With the size of stepper motor you showed, any ' step stick ' stepper driver should work and the variable resistor on those boards should follow the practice of 3D printers where the motor attached and the driver powered up the center adjusted to max voltage ( not measuring resistance as that is not holding force, it is movements ). I can be wrong on that, feel free to reply with otherwise. Almost any MPU could work with the data to drive the step stick and I still recommend having part of the launch sequence not just start recording, take ' current rotation ' at the MPU driving the rotation then applying the difference as it launches with a delay of no greater than the time to clear the launch rail. You don't want to get stuck on the launch rail by a camera. This is still awesome as was and hope some of my view on your progress gets you closer to where you need to go. ( Moon shot with rover?? )
Joe, I put this comment on the video on your main channel, and I'll put it here too. You are way too hard on yourself - that footage (for a first or second-generation design/build) was absolutely AMAZING! You are an incredible engineer, machinist, and rocketeer!!
One thing to remember... Every action has equal and opposite reaction... The movement of the spin device is pushing the body of vehicle away so you get 2 times the roll rate
Yes and no. The mass of the spinner versus the mass of the rest of the rocket is important. It may add to the total roll rate, but since the rest of the rocket is so massive (lots of mass) it’s inertia will make the effect of the spinner way less than doubling the roll rate.
My favorite part is when the camera goes "it's spinnin time!" and then spins all over the place
Camera go brrrrr weeeeeeeee
My favorite moment of all time.
Definitely one of the cameras of all time.
Yep
Pretty darn good for a first attempt.
I like how the camera goes crazy on the way down
I believe this worked much better than you told in the main video. Cannot wait to see the rapid improvement on it.

Maybe a 360 camera on a rocket with the footage edited for whatever benefit
3rd lol! Amazing footage.
Why can't you use a reaction wheel
I mean… it landed in a planned and assembled mode.
Cool rocket , u should have documented the build and design process as well. Video makes no sense there's no context
It's all documented on the BPS.space TH-cam channel - the videos are about my Level 3 build process and were published in the spring of 2022
