Great to be here

@valerio I do not apply microelectronics first hand to the rocketry. But the whole Guidance, Navigation and Control area of rocketry has to deal with similar computing challenges and setups as the other stuff I do with microelectronics. So that is a field I wanna get into deeper. Only things I can directly apply on my very subsystem on the rocket would be design of a power supply for linear actuators and vehicle dynamics also regarding these actuators, but mostly software wise.

Unfortunately this is mostly outside of my knowledge.                                                                                All the vehicles that I've made use simple algorithms (ex. move eight servos in sequence for my walking robot) and are controlled with an Arduino, so that seems quite different from what you do.

But I do know some youtube channels which make video about rocketry, like rctestflight and ProjectAir.

Nevertheless, I hope you enjoy your time on this forum.

Have a nice day

@zander thanks for the explanation

@inq thanks for adding the picture I have forgotten to link. The crew is often also international even when mainly german. Especially the permanent crew knows english very well. Sometimes a whole watch is set to be the international one and english is used as the primary language in that watch then. Depends on the location of the trip wether many internationals are aboard or not. 
And I have forgotten to ask, but what does AE stand for in one of your first posts?

I was not really serious.  Although I would love to be on a ship like that, would do it in a heart-beat even now, I'm only qualified to be a swabbie.  I'm not quite limber enough to be climbing in the rigging.  🤣 

AE = Aerospace Engineer - My school had three sub-majors - Astro physics, Aerodynamics and Structural Analysis.  I was S.A.

@valerio RCTestflight is such a great channel. And when it comes to rocketry I can recommend Joe Barnard with BPS.Space. He gives insights into his progress of building and flying model rockets. Definitely worth a visit!

I checked out the BPS.Space link.  Really interesting.  I used to do those rockets... oh nearly... 50 years ago.  Interesting... doing thrust vectoring.  I would have thought those motors were nearly expended by the time it left the launch rod.  

One of my buddies is an 8th grade Science teacher.  I volunteer when they do a class project using 2 liter water rockets.  Typically they use poster board for fins and traffic cones for the nose cones.  It typically is mostly about getting wet and goofing off outside, but some of the students accidentally learn something.  😉 

Before Covid canceled this kind activity, we wanted to explore/demonstrate making design changes.  From a rocket perspective, we wanted to use different rocket nozzles to compare and contrast higher thrust / short duration versus lower thrust / longer duration.

We were looking to instrument it with the camera (shown above), but later we were going to use an ESP-01 with a GY-89 Gyro/Accel/Mag/Barometer sensor.  Then we do real-time telemetry back to a large screen TV so the students could see the data and the rocket flying at the same time.

It might still happen for future classes... we'll see.
