Martin Lydon Hey random stranger, I do not know what you are going through, but I know what I went through. If you are similar to how I felt then you are probably really depressed, feel alone, and anxious, and maybe even going a little insane... and I am not here to tell you it is as simple as continuing living. It’s not. You probably need a big change in your life. New job, different classes, or whatever. My point is that you just need to be patient and work with what you have. For me, I changed programs in school from mechanical engineering into the automation field. All of a sudden I was doing stuff I couldn’t have imagined months before. It made me excited everyday to wake up and go to school, or now a days, work! The truth is that it’ll be a difficult road, but you stick to that road, and you may find an intersection full of options. Options that you will look at and say “It was all worth it. All the pain, the loneliness, the sadness, it was worth it.”. It made me see life in a new light. Like I had a purpose. I hope at the very least my message gives you hope, and it helps you understand that you aren’t alone in that feeling, and that there will be a silver lining. It took me two years and I still have days where I feel beaten. But I have more days where I feel like a king, where the world can’t stop me from being glad, and I hope you get to that point too. Because there truly is no better feeling than knowing you conquered your lowest point in life.

Really cool PID explanation. And btw your progress on Sprite is amazing. I don't know what's your plans for the future, but with all that knowledge BPS might be within few years delivering components or services for commercial cargo landers (moon or planetary stuff). Am I crazy? 🤔
Agreed. Last thing we need ist for velocity to be represented by (royal public hair length)/(time until a stone dropped from the tower of London hits the ground)
None of your "rough video quality" impacted your presentation in a negative way for me. Great job!! I edit "rough" videos of others all the time. You Rock Joe! PS: try unplugging the HDMI and reinserting next time, could be a quick fix for screen issue.
3:25 currently at Florida tech, doing a design project on point to point launch and landing at the model scale. Was genuinely shocked when you mentioned vector bravo! Good vid
Brilliant presentation, especially loved your summary of PID control. I've been tinkering with GNC in Simplerockets 2 (which is basically a more technical version of KSP) for the last couple of months and it's so interesting to hear you explain something that took me all those weeks to sort of "reinvent" myself. It's kind of fascinating how so many people end up with the same solution to a problem.
I'm a D to F candidate in math and physics (by idleness)... and I still watched the whole thing listening to a whole bunch of words I only have vage concepts of in my head and I still enjoyed his enthysiasm. xD
“And I’m being Really exhaustive with covering all this stuff ” did no one else find this pun! Hilarious 😂 And thank you for sharing this, I would like to get into this type of thing when I actually have money so huge thanks
its just incredible: i just was coming to your channel again after few days so i could ask you for the stuff i need for a school project and now... i dont need to ask you answered all of my questions without hearing my questions xD thank you :)
Awesome. I would love to see a more in-depth video on the whole control analysis. I’m taking control of dynamic systems in college right now, and I think it would be awesome to see how you solved a real problem with it.
Thank you for this Joe. I started playing around with arduinos a year or so ago but I could never find the right application to learn about and loose myself in. Then I started 3d printing water rockets for my kids. Omw how much fun is that. I'm so glad I found your channel. Let's see if I can get a few things up in the air. Great work man!
So I've been writing scripts for KSP rockets for a while now, and kinda got scared off from PID controllers since I didn't understand them. Thanks to this ( 33:00 - 42:00 ) I now understand exactly what they are. I can even identify that I've written mostly proportional controllers, but I also a Proportional-Derivative controller on one occasion. Thank you so much for this. It's so hard to find good verbose descriptions of these things online
In gliding we use the MS5611 barometric pressure sensor a lot. They might be more precise than what you're used to, but the membrane also acts as accelerometer if you have vibrations.
Thank you soooooo much! I started an aerospace club at my college. We're starting to work with weatherbaloons right not and this talk was a huge help with the hardware!
Great video. Now that small hobby drones are popular, we have readily available tiny control boards with the microprocessor and all the needed sensors pre-built. Much smaller and more suitable than something like a Pixhawk.
I is what will get u back on track. Removes offset. D is what is responsible for quick changes and future predictions. However it will/can cause “windup” the fastest, and needs to be looked at closer than I. Windup will occur faster with D than anything.
Awesome explanation I'm currently trying to build my first tvc controlled rocket and it already helped a lot. But I have one question if you're simply adding the derividive back into the loop you'd get, in your example, 1°+2°=3°. wouldn't that mean that you're accelerating even more since you're pushing the engine even further outwards Did I miss something or is there another problem I just don't see.
Very clear presentation on your project! I am a nerd on this topic but I understand what you mentioned. Thank you very much for showing us what you did. Congratulation!
Wow.... PID controller huh? Amazing how nothing changes but the names. Pretty sure this used to be called a servo control loop back when I was younger 😂😂
I was wondering about the use of a sliding tube for variable Krushnic effect (fine down-throttling, especially at landing) combined with four side ports in that tube which would be opened and closed to possibly cause some degree of thrust vectoring.
IMUs have high sample rates, but BMPs have very low sample rates coupled with some hysteresis. Is there a modern alternative for determining altitude, besides BMP and LIDAR?? Please and thank you! Great talk.
Great info - thanks! One thing: at engine burnout, at any real velocity, there's usually quite a large deceleration. I'm confused by the statement around the 22:00 mark that acceleration at burnout is zero. So this assumes a positive acceleration only, yes? This negative acceleration (deceleration), of course, has been long used to actuate staging switches in model rockets (originally, mercury switches).
Hello @ Matt. In what way is the 388 updated from the 280? Just asking as I am in the middle of this serious learning curve here. I'll compare both nevertheless.
what i find to be awesome about Joe Barnard is how he says smart stuff in a funny way. He always gets to the point, but usually throws a laugh in their. its not a skill many posses.
This was TERRIFIC! I have only one suggestion and that is to balance a broomstick (preferably on your nose) as a graphic representation of the forces and logic (and difficulty) involved! 👍😎
Came here to meme about how did I end up here (SpaceX binge). Ended up watching the whole thing, refactoring some code I was working on to be more "state machinish" and dusted off my old (3 years) arduino kit and googling projects to get back in the groove.
For uC selection I think I'd opt for a esp32 for the dual core processor, then dedicate one processor for guidance/tvc/pid and the other for everything else.
Can anyone explain to me how the calculus behind it works? He explained about the integrals and derivative between around 30 to 40 minutes but I did not really understand. Would the calculations be of a function of degree change over time?
