This is maybe my favorite BPS Space video, which means it’s one of my favorite videos on UA-cam. Great work Joe!!! Thanks for the knowledge, laughs and fun!
🔥🔥🔥
Wow! Hello Everyday Astrount
By far the best and most authentic video ever! It was amazing!
I concur Tim.
agreed
I love your energy. Especially the "oh god why is everything awful I'm going to slide down my chair onto the floor now." It feels very authentic. Real, not glamorized engineering.
No comments? Dang also nice comment
You remind me of an Elon Musk with upgraded comedy software.
@@grant0617 I don't know how to respond to that. Thanks I guess? I meant my comment honestly. The whole sliding-down-the-chair-in-despair thing is quite familiar to me, and I appreciate content that shows what engineering is really like. Joe manages to strike the perfect balance between entertainment and reality. A video diary of the entire process probably would not be much fun to watch, but I don't want to see just the successes. If I were on an engineering team with Joe, he would be the one who kept everyone going even when nothing was working.
@@EthanReesor I am a dumbass. I accidently replied to your comment when I was just trying to comment on the video, referring to Joe. You must have been so confused. I never read your comment until now, and I think we were making the same point; that Joe is a genius, as well as being very relatable and humble. And you made an honest attempt to reply to my accidental reply, which in itself is remarkable and rare on UA-cam. I'm so sorry to have wasted your time. I'm going to leave my comment up for everyone to see my stupid mistake. Take care, Ethan.
yes I was close to say the same, similar, ... well not let it get weard!
12:16 was mind blowing. Totally awesome.
Absolutely
Amazeballs!
ong bro
nah this here is mind blowing 0:38 thats how we work what a great job
I will never get over just how spectacular you are at making beautiful (and also funny and educational) videos. Congrats on an absolute BANGER
Also le soundtrack be bumpinnnn
Wow, Xyla is here! 😎
He’s designing the boarddddd
About 10 seconds into this video, I thought, "Man, Xyla should see this..."
I really should have known you already had.
@The mRNA jab Is the mark of the beast tf
@Xyla Foxlin >>> Are you and Joe RELATED by any chance?
Uh, asking for a friend...😉
Wow, the transition into 12:22 is absolutely top tier! Amazing work as always!
even the deer thought so too :)
"We don't want magic smoke to come out, because it's really hard to put the magic smoke back in"
This is one of the most beautiful explanations of entropy I've ever heard!
Hello Icarus Thiccarus, I hope you're well. Thank you for teaching me about grey sauce and magic squares. Your T-shirt speaks to me at a fundamental level and that one part of the video was transcendental and changed me as a person for the better.
I've been getting pretty good at putting magic smoke back in.
Oh, and I'm going to need the rights to this song for future videos, just fyi.
The 12th minute was amazing!
12m30s: That was AMAZING.
Actually, it was. The last stage was unstable-as you said-but that was a solid multistage flight. Well done.
i haven't visited your channel in quite a while. It was always entertaining because of what you're doing and how well you communicate that and your enthusiasm for it. But I see a real quantum leap in your production and entertainment value, story telling, stray deer, moon rise, BPS interns, musical Shre-e--ek accompaniment and all. You're a pro youtuber. Very well done!
you can say 12:30
Just FYI, for precision tech, especially digital applications, I'd recommend 4 layers: with 2 signal layers, and 2 hidden ground planes. The signal layers can create enough EMF in smaller electronics to induce signals into nearby circuits. A ground plane directly beneath both signal layers will protect against that.
So signal ground signal ground? Or signal ground ground signal?
@@AB-om4ls prolly the second one
@@BMac420 Nah he said directly beneath both. So that means directly beneath Signal 1 and directly beneath Signal 2. S/G/S/G
@@Jeremy.Bearemy if you're designing a 2 layer pcb you've signal panel on "top" of the two side, in a s/g/g/s arrangement, each face is a signal plane with a ground one just beneath. i'll put my2c on s/g/g/s as @B-Mac
the not including of a log was the worst.
How can you debug the Code without jtag and without log?
Can you buy these boards? asking for an Iranian friend who is asking for a Russian friend who is asking for a Chinese friend who is asking for a North Korean friend.
My Talibani friend's Iranian friend told me that these are dirt cheap
The climax of the video is at 12:15 and it couldn't be any better!
Soooo good!
Very good
Hi Marcus 👋
Hey hey
Very
man
Joe, whether you know it or not, you are promoting the idea that it’s ok to fail because it’s still an opportunity to learn,and that’s inspiring. You are an inspiration. Keep up the great work.
Cheers from Moose Jaw
Tim
After many years he finally used his audio degree.
Lol
🙃
I've actually been thinking about """streamlining""" the process for a big (huge) project I'm doing (go direct to the final version, what could go wrong?), thanks for being my test subject on what not to do.
We’ve all thought this. 😂
there is no such thing as a final version
@@starry4471 final version
vinal version rev 0.1
vinal version fix

😂
@@starry4471 as a software dev I couldn't agree more, goalposts keep moving forever...
1:58 "We don't want the magic smoke to come out, because it's really hard to put the magic smoke back in."
What a fun way to think about frying a board. Due to conservation of mass and information, it's technically possible to put every atom of material that was combusted back where it belonged to make the board work again. It's just "really hard." Lmao
"....I crave external validation!"
That earned a solid like and sub. Keep it up. Failing is success.
OK fine, have my sub as well. Group pressure
external validation is best validation.
12:16 oh man this was the climax of the video, incredibly well done editing at this part
This Chanel is, put in a simple way, extremely satisfactorily.
Love the rockets, your thought prosess, and your filming/editing skills.
Actually to get 2 stages to fly straight without fins is impressive. How many times did Rocketdyne have F1 engine failures in testing before they got it to the point that the Saturn V 1st stages never failed with crew on them.
.. How many times?
Is it safe to say that in rocket science, there are either people who are built different and decide not to record any flight data or rockets that are built different that decide not to record any flight data, and everything else is just all the magic smoke building up in high enough concentrations to actually make things magically work? 😉
You summed up debugging
My god an actual rocket company this is crazy
@@alt8791 Not a company, just a group of volunteers building rockets in their spare time. 🙂
@@CopenhagenSuborbitals I think it's fair to say that you are THE institution within the field of rocketry in Denmark. Glæder mig til jeres fremtidige videoer.
In rocket science there's two kinds of magic smoke: The fiery smoke that makes your rocket go up and the sparking smoke that makes your rocket go down.
The montage of creating the board was true art
"Maximum Ogredrive!"
-Joe Barnard 2021
"You squeegee the grey sauce onto the magic square"
this guy is a treasure trove of hilarious sentences
12:00 This part of the video is amazing. The climax right here.
The segue into the 4th launch was an instant UA-cam classic, and possibly motion picture history being made. The storyline. The footage. The editing. The casting of the main characters. Even the catering, as shown through the fresh and healthy appearance of the cast. Wow!
"If you drop one of these on the ground it ceases to exist." Oh so true. LMAO
Guitar pick feels also... 🥺
YES. THIS.
Also, 0402 components are a great way to learn about complex / imaginary numbers... like when you assemble 9 LEDs, and you ordered 20, so... 20-9 = 3 left.
Listen ok conservation of mass is a myth made up by nasa
Do you sell your demo CD after the concert? "Designing the Board" sounds like a hit to me.
At the very least I hope he registered it with a content matching service, otherwise someone else will and then claim all his hard earned monetization because that's how broken the UA-cam system is
The climax of the video was amazing! It truly captured what it takes to turn new ideas into a reality. It's easy to feel like you're done at that point because it's not talked about enough. The leaning back in the chair is so familiar, I was smiling right through it. Keep up the great work. I loved the video.
Music slaps on this one
Please make “designing the board” a full song!
-> Bo Burnham
Yesss, make it.
Drop the whole album please!
re: logging: An oldie (but goodie) is an ATMEL DATAFLASH. Only 8-pins and an i2c interface! Got two spare GPIO's on your MCU?
Your videos do such a good job at demonstrating that "failure is part of the process." And with the right attitude (and healthy self-deprecating humor), failure isn't to be feared, or even to be avoided to the point of progress-lock. It happens. I hope people get that.
Oh and I sincerely hope that I am appropriately feeding the algorithm here. Your channel and all the supporters deserve more views.
"maximum ogredrive" just made my day
This is one of the craziest projects I've seen on youtube. Honestly man, congrats.
Omg that was amazing!!! My favorite part was his intellectual knowledge he gave us before the 4th flight, very impressive! I don’t think even my college professor could match to your level
Must be an American professor 😅 In Germany they are next level smart, literally all of them that teach physics or electronics.
So when do we get a full BPS.space album.
Cause like... we need it.
Even if it requires my patience.
+1, these are bangers
We need that as a KSP official OST
Great video - The deer stopping and looking at you on the 4th flight - You could almost hear him ask 'Are you collecting flight data this time?'.... 😄
i mean, holy shit, this was so amazing. right around minute 12 was literally the best moment i have come to witness in the entirety of my existence on planet earth. simply breathtaking, except even that doesn't do it justice.
I was looking at the comments while watching this, and I saw a few comments like this and I was so hyped for that moment. I really am so insanely stupid.
Between the silly song and the decent into madness (which honestly was hilarious and one of the best parts of the video) it really looks like you’re having fun with your projects, which is great to see. At the end of the day, such a cool idea and fun to watch you having a good time!
This has to be my favorite video on UA-cam so far, maybe tied with the magnet spinner episode or the correcting section on the fins episode keep crushing it
When you forget Joe has a music degree and he pulls bangers out of his ass.
Thank you for making my day better with that "designing the board" segment lmao
Step 1:no wings
Step 2:no safety motor,buggy code?
Step 3:This part of the video is amazing!
Yet,not lighting for stage 2?
Step 4:Great work!
No schute?
Petition for Joey B to only refer to solder paste as “grey sauce” from now on ✅
Upvote for spelling grey correctly
I’ve seen very talented engineers spend days sitting on the floor by million dollar machines pulling and smelling boards look for the source of the magic smoke.

- Joe Barnard (BPS Space)
The “chair slide” is a completely underrated coping mechanism for dealing with challenges. Just sayin.
agreed 100%
OMG that design montage was delightful!
That first launch reminds me of a time long ago when I took a model of a General Lee and turned it into a rocket car. It started off great (without doing the math but careful assessment of weight, balance and guessing the thrust). It went straight for about thirty feet, curved toward the right, hit the side of the local junior high school track, launched in the air, spun around like crazy and exploded midair. It was a blast.
Can we just take a second to appreciate the video? The writing, the cinematography, the music.... pure perfection
It's brilliantly, brilliantly composed. No joke. I enjoy watching his videos for the directorial choices alone.
"we don't want the magic smoke to come out because it's really hard to put the magic smoke back in" got me
When you get the bugs ironed out, you can build a rocket to go up to the edge of space with multiple cameras to see for yourself what it looks like, rather than relying on what NASA wants us to see. Recovery would be another issue unless you have a quad copter made on it to activate return to home. Just a thought
This was fun, and this video shows how you review what you have done, critique your effort, and get better with each iteration of a project. Well done!
Dear Built Different,
I sooo enjoy your videos especially the transition to the 4th flight. I don't want to say I enjoy seeing the unsuccessful flights, but I do enjoy watching the problem solving process, the creative energy and ideas. I am more mechanically inclined and I want to want to be more programming savvy. Please keep up the great work. We are rooting for you.
Honestly, EVERY aspiring engineer needs to see this video. Nobody’s built different - physics befuddles/exhausts/schools us all equally. Your one video is probably going to save billions of dollars and who knows how many lives down the line.
You didn’t phone this one in, you simply made a very common mistake, and had the good grace to keep it all on film. Good on ya dude.
And no kidding, that montage music is my new jam. Your rockets flew at least a little, nothing seemed to blow up, all of it was designed to withstand the foreseen failure conditions, and most importantly: the safety protocols seemed to function perfectly. Overall, great work!
Just know that this energy and vibe is what I carry from BPS into Starship development!
Xyla said you might be coming here to film with us. I'm curious what HS camera you use.
Why do all these rockets fly short and crash
@@STEEPPOW except for the high power stuff Joe has been focusing on low level flights for their stunning visual effects and system development such as stages and landing. You don't want to fly to 1k plus feet for every little system test.
@@STEEPPOW Complexity and efficiency vs dumb shit brute force.
The later is crude but reliable, to a degree; the former attempts finesse, but is far more suseptible to 'weakest link' failures.
didnt expect to find you here, are you potentially planning an in-flight guided bullet?
Record the flight data with a secondary controller that’s links to the primary one and then once you have it tuned in after being able to “learn the error of your ways” then use all that same data for your “worlds smallest rocket flight computer”.
I think this is one of your best videos yet. I really love how you bring us with you along the process. It's extremely inspirational to watch how you respond to the challenges that prop up. Thank you!
Thank you Joe! You are refreshing as well as an inspiration. It is wonderful to see you so exited and enthusiastic. Keep having fun.
"I'm Joe Barnard and you're watching BPS Space" had me shrieking out loud alone in my room, good lord
No, it had you SHREEEKing*

Broke the first rule of Rocketteering.
"Didn't take into account that the missle needs to know where it is by knowing where it wasn't, and by knowing where it isn't, the missle knows where it is doesn't need to be"
Great video.
Oh shiiit Barnard posting time to hop on! Liked the NSF interview, wish they would've read my question and put you on the spot for why it's Barnard propulsion when propulsion is the only thing you don't make lol
That part on sage four of shreeeek when the deer was there was pog.
I didn't even notice until editing! I had no idea it was there in the moment, too focused on ShEEEk I guess :)
@@BPSspace Sheeek
@@BPSspace really missed out on calling it Shreeek 2, Shreeek the Third and Shreeek Forever After.
Maybe I missed it, but If that was me, I'd be moving the rocket off vertical by hand to check if the Atmel chip was programmed right to correct the deviation from the IMU ground direction reporting. Also, your take off G-forces should exceed gravity, so you need to have a fool proof way to analyse the IMU changes under real world conditions. You can do this by mounting your tiny circuit board on a drone with a couple of tiny servos and then record it's attempt to correct actions as you shoot it up into the air. Make sure not to swap your x and y servos! No logging required. speaking of(writing of) logging, most of the Atmel AVRs have on board user accessible flash. Check your chip's flash size, data set to record and set it to write from takeoff, with more speed for early stages as those are where you seem to be spending more time.
Apart from that, great video, refreshing change to see attempts, too many people on here obsessed with only showing their successes!
This entire video feels like a UA-cam short
"I am... *not* built different". Laughing out loud in my chair. Love it! Keep going Joe; we are loving what you do. :-)
Decades ago (at Scientific Atlanta) I was caught looking under my solder-station by my manager for a Resistor that I had dropped, and he said: "What the hell are you doing?" Me: "I dropped a part and was looking for it..." He said "I'm not paying you to look for a worthless part, I'm paying you to install them, so get another part and use it. What makes you think you found the same part as you lost anyway?". Wow!
I could not fault his logic, and did so immediately. This was back in the 0804 sized part days, and this mindset is much more true today with 0402 and smaller parts, and will be forever more. Maybe even for CPUs!
Joe: I built a custom tiny rocket flight control computer and soldered tiny SMD parts with my hand.
Also Joe: Shreeek
This has simply taught me data logging is even more important than I thought. And I already thought it was pretty damn important!
feedback is surprisingly essential during a development process
As an alternative strategy you could add a drill on the top of the rocket, so when the flight controller decides to steer the rocket to ground instead of sky, it can dig through the earth and come out in the sky of the other side when it all makes sense again
Thanks for the board design sequence. It was a detailed and thorough breakdown of your thought processes during the build.
That song and "build montage" might just be the best thing I've seen all day.
12:10 is what i came for
when will the next episode of landing model rockets come out for blip and blop?!?!?!??
Hate to break it to you, it's not.
@@shlok975 WHAT!!!!
HOW COULD YOU SAY THAT NEVER UNDER ESTIMATE JOEY B.
he needs to add to the series again.
@@bozothejew4850 I'd be only too happy to have another episode but he used to upload every episode within 2-3 months of the previous one and sometimes even with a gap of only a few days. It's been 2 years since the last episode.
@@shlok975 yeah lol
Love your work. Failure will teach you. And the line "everything worked" is a sad short beer story
"It's really hard to put the magic smoke back in" that made my chuckle
Pleeease joe, this kind of video has a quality that is so rare on youtube these days. Please keep going!!
LYRICS for “Designing the Board” by Joey B:
Verse 1:
He’s designing the booooard
Now he’s routing the traaaces
**presses delete for some reason**
LOOK AT HIM GOOOOO
**aggresively slides over keyboard*
PLACING THE ORDEEER
**spills water everywhere**
Outro:
**j u m p**
Smash that like button I crave external validation.
**chortle**
12:25 i would say perfect who is learing programming for the same purpose at the age of 40.
All stages deployed were at par.
Work well done.
"i crave external validation" OMG i laughed so hard. (and pressed like)
This is SOO GOOD, and you're one of the model humans I use when aspiring to do great things!
from my observation in the last minute, i.e. in the failure of 3rd stage, in my opinion, the problem with the 3rd stage control is due to reaction wheel control you are using. I mean, in the first stage, everything looks ok because your mass is enough to balance the system where the reaction wheel can "actuate" and control the rocket, then, the second stage control, still ok because you still have some "mass" to balance the rocket, then, at the third stage, the mass significantly reduced so that when your reaction wheel try to control the rocket, this reaction wheel lose its counter weight so that your overall parameter system is different. That mean, what ever your tuning gain was used, it cannot stabilized the system anymore. My humble suggestion is, try to use "robust control" like gain scheduling or adaptive one.. the idea is, for each different stage your tuning gain would also different so that the reaction wheel would "adapt" with different parametric system.
I feel like the making of the board section was the most informative circuit tracing software tutorial that has ever been put to any form of media.
Also, that song was fire. I need more of it.
Yep, when people say some projects are a waste time, I always tell them it doesn't matter because it's fun :)
Amazing content as usual. Your camera work is on point! Loved the humor, excellent video!
Just eyeballing the flight, it looks like you have hunting and overshoot. That's where gyro correction overdrives and then reverses, inducing oscillations. What I see here is almost an updated video of 1950s gyro stabilized rockets.
By the way, my Dad taught me about hunting and overshoot in compasses while we were boating in the Atlantic. I was looking at the crap on the Bermuda triangle and insisted that a fluctuating magnet field was the only way to make a compass spin. He proved me wrong by swinging the bow of the boat repeatedly and the compass spun like a top. The compass card would lag alignment N-S due to the viscosity of the fluid in the binnacle and shoot a little past the alignment N-S, then return. But by keeping the bow swinging left-right, the oscillations would increase until it began to rotate.
It really does look like that's what you have going on here.
That conservation of mass gag really gave me a hearty nerd-laugh
This is insane and I have enjoyed the progress off your space program over time!
Honestly this was my favorite BPS video to date, nice work man!
Great. Now I have “🎵He’s designing the board🎶” stuck in my head for who-knows-how-long…. 😆
And that one part was DEFINITELY the best part of all. Definitely.
I nearly choked while laughing during your deigning the board montage. So hilarious. Good Job.
I don't have words in my vocabulary to appreciate this video and everything related to it in most humanly way possible. I might just edit this later when I come up with.
I think you did great! You kept trying and made great steps forward. You learned lots and had fun. (remember the fun, forget the frustration) If it were easy, everyone would be flying multi-stage rockets.
I've had this question for a while: do you run some sort of RTOS on your flight computers, or just a bunch of functions called from a runloop?
In one of his earlier videos, Joe talked about data logging taking place at 40Hz. I don't remember which one it was, but there could be a scheduler (at least) with a data logging task that executes every 25 miliseconds.
@@akhilathawale725 data logging? Who would do that? Are you not different or something?
@@simonabunker hahaha got me there. I pretended not to be, but realized I am. #wipeallbackups
40Hz is so slow for me. I have a 20mm x 82mm datalogger collecting 7 channels of data at 500Hz and 3 channels at 5Hz as a typical configuration. It's still a prototype in testing. Looking to fly it in 3 weeks. Joe and I are going down different paths within the field of rocketry. We are both making advancements, that I hope others follow, in our specific fields of interest.
You tick all the humor check-boxes, but you are still a serious designer! Enjoyable and informative... sounds like a TV slogan!
We love how you love the process, Joe. Great video.
"Little known fact; if you drop one of these parts on the ground it actually ceases to exist. Conservation of mass does not apply here it's just gone."
SO true.
Yep! The old look down and follow it trick one learns after dropping one too many small parts doesn't apply for small SMD caps, resistors, diodes. Best to just order three or four extra!
Use some light nearly parallel to the floor, the multiple times larger shadow is much easier to see (if you have an even floor without many bumps)
