"Shredding the rocket would be pretty cool" - Joe Barnard

The most true thing Ive ever heard. "What did all this cost you?" hobbyists of flying things: yes

[@jeffvader811]

Since the mass of a rocket grows with the cube law, but area (and thus drag force) grows with the square law, big rockets have less of a problem with drag force.

@@IOwnThisHandle nonono, you're reading it wrong. The question here is "what did it cosine you to build it?", to which the answer "yes" makes a lot more sense, as this naturally means the solution to cos(cost) = positive That's quite a usefull answer, because it eliminates half of the possible solutions. edit: "answers" to "possible solutions"

[@blantondavis]

Geez as soon as you explained the problem with using PID when you didn't have a constant thrust from the motor my brain started churning. I KNEW that the instrumentation you have onboard could solve that problem and at 6:50 in the video I yelled out loud OF COURSE YOU CAN SOLVE FOR THRUST BECAUSE YOU KNOW THE ACCELERATION. I love it when you get to do useful shit with all those physics equations we programmed into our TI83s in college to cheat on the test

So very cool I remember going to LDRS 3 in a field in Ohio in the eighties when I was a little kid. I used to know the original owners of Loc Persision, North Coast Rocketry and Stargate Rocketry which was my father's company. My family were some of the 1st members of Tripoli. I am now 43 and it brings back so many cool memory watching. I am amazed at what is being done and amateur rocketry nowadays.

Q: How would you keep track of the telemitry for 1Km and beyond... A: some form of syncronus communication similar to 5he videos on how a Raspberry Pi can transmit video over 10Km. Transmitter on send inly on known channel, reciever set on listen only mode. It potentially can be done with nrf21n1 with whip antennas, the ESP32s would be a better option as it could do encryption on the data as it transmits. Keep up the progress, if I was going to discuss this at partirs, they would be Virtual as the only virus I could get is potentially a python script.

[@unrealreality.design]

[@JohanLind]

Huge improvement over Flight #1! Way to go!

[@microelectronics5732]

Your idea of building a controller around the torque, that's the way how we've got teached to set up a control loop. The first step is to describe your system in diff. equations. Reduce it to a first order system, solve it numerically or feed it into your PID Control.

[@LawrenceBrennan]

That was one well done Q&A session!

[@metaforest]

wow that launch vector recovery was smooth and fast!

[@Strelnikov10]

So, I bought all of the equipment to do a similar project back in January. I plan to build a TVC mount and train deep neural networks to fly it (I'm a data scientist). Kind of like an onboard pilot, but instead of a human, it's an AI who's entire brain is dedicated to the act of flying and who's neurons work at 2Ghz.... I will make videos detailing the process. I think that an AI approach will significantly aid in the landing process (which is what I intend to focus on). Particularly in the realm of visually tracking towards an intended landing site. Joe, as a Space Camp alum (and "Right Stuff Award" recipient) who sadly never ended up going into aerospace, this channel has been a MASSIVE inspiration. This is like living a dream all over again. Much appreciated, sir. Now I'm isolated at home with all of these materials and microcontrollers/sensors.... what to do with all of this downtime? Haha

[@tec4303]

The Q&A section was just ... perfect.

[@readysetnogo]

Just a tip with filming to reduce the noise/graininess in the image while filming in the dark: reduce the iso and lower the f stop to let more light in. There's a balance that you can find between iso and aperture to get good exposure and reduced image noise. I loved the video. Inspiring as always.

[@michaelaguilar9751]

Mate, your deviation from Echo to Sprite to Sprint has not stopped me from watching every video you've put out, as soon as I possibly can, (usually within the first hour or 2). If it flies, we'll watch it, if it explodes, we'll watch it, if it lands, by god we'll watch that too.. Nice subtle gestures in the final minute too.. wonder how many people caught that..? ;) Look forward to a Sprite with Echo legs.. :)

[@dmjimageryltd]

Very nice flight

[@DANHjAM]

Awesome channel! I’m involved in the DIY quadcopter and long-range fixed-wing drone building community and the speed of development in that hobby has been quite mind-blowing. I can certainly see a similar potential here for model rockets and this new way you’re building and flying them with thrust vectoring and adding in control software and flight computers. A lot of people will be interested in building these types of rockets, for sure. There are some comparisons here to how flight control software has revolutionized quadcopters in such a short time. It might be quite fun to add into your rockets some long-range video equipment to get a live feed and on-screen flight data in real-time. You could add something comparable to Betaflight OSD to give you live on-screen flight data (speed, altitude, range, and GPS coordinates). It’s pretty cheap to get this equipment and fairly straight forward to add-in with a bit of research. If you use 5.8ghz video equipment the antennas are small and could be embedded inside the rocket too. I get about 5km of video range on my 5.8ghz FPV setup. It would be fun to combine some of these developments into model rockets. Anyway, great work! I might have to build myself some rockets now, lol.
