THANKS ROB
no bob
Yoo just discovering this channel but who is he??? He looks sooo familiar
@@Takeyoho Yo its me
Kewp Time Elon musk
What if I rip off the rip off of your design
"Overvolt your servos if that's who you are as a person" Hey man I feel offended. There a 10% tolerance on most electronics for a reason!
"I paid for the gauge so I'm gonna use the whole gauge"
When there's a will, there's a way.
Ya so you can undervolt them but if you buy them in a 20 pack and rust them out intentionally maybe you should give some old rusty junk to your patreon supporters?â€ïž
In my rc rock crawlers I overvolt my 6v servos to 7.4v ;)
Yes but they fail faster
This channel is like the greatest rocket documentary ever
Yeah sure
The sequel to October Sky.
Yes I too agree!! Also, I like Copenhagen Suborbitals!
It's Probably because Elon mars's twin brother.
Now the tough choices - aquafina or dasani water tower for acoustic suppression
Fiji duh
Of course carbonated milk!
Dieter MacPherson nah we saved all of that water for my aunts gender reveal party next week
Tom Scott taught me that the Dasani water will be contaminated.
Tears of the doubters.
5 years later: so in a few weeks we will attempt our first orbital launch
2:20
As much as I love designing all my projects myself, when you find a cooperative someone with a legit idea that you can really use, MAN does that save time and materials. Its a great feel
This is so cool I canât wait to see it launch and then land. Best of luck
Love the excitement Ian. Im excited too.
Yeah, I've never seen a launch pad launch and then land again, should be super exciting
You have 4 motors actuating four clamps- they are never gonna all release at the exact same moment- you also have 4 times the chance for a clamp delay or motor failure.
I suggest you actuate the red clamp props all simultaneously by making a RING with a crown gear run by a single pinion geared motor so that 4 pins protruding inside the ring all strike the red props at the exact same moment. Alternatively, you could make the Ring Spring loaded so that it is counter wound 80 degrees, just shy of the next clamp over, to a single catch that when released would release the sprung ring to accelerate thru 80 degrees to strike all four clamp props simultaneously and with enough momentum to overcome any amount of upforce on the clamps.
Either way- a large ring with cam pins, spinning outboard of the four clamp mechanisms offers a sure fire way to be certain that all four clamps are struck and released exactly at the same moment.
Christopher Pardell i was just going to write the same thing.
Or he could use explosive bolts to release it...
Might not be practical, but would be cool.
@@zenithparsec it would be realistic!
I thought of the same idea. Instead of the red pins have the large ring. Put a long ramp and cut out for each yellow hook. Now the ring can rotate one way to release and the other to lock the pins back in place.
The issue i see with that is for triple core launches. The current mechanism allows for him to move the clamps where he needs to. A single ring would limit that and would require a completely different mechanism. He doesn't seem to have issues with the timing of old set up, i assume that he's confident it will be just as reliable. At 5:37 he has slow motion of them actuating, one is slower than the others, but he stated that it's functionally irrelevant. Cool idea though.
8:55 "I said that a landing test would come back in August, and as with any good rocket project, it is delayed."
Truer words have never been spoken
Well he said that almost a year ago so like what happened (I know there is lumineer and moving and shreeek but like still
Mentions legos:
*Jerry Rig Everything has entered the chat*
"Black powder motors will light when you look at them the wrong way" LOL
Not a rocket scientist but shouldn't the firey bits go __into__ the flame trench đ€
the igniter goes up into the rocket motor to ignite it.
Bob _into_ *just testing*
Oh ya ya it works
I never skip the CZcams advertisement in this channel....to support BPS â€ïž
Iâm so hype for this up coming project best of luck to you. Happy to see another videoâ€ïž
missed these High Quality videos; good to see you back. Can't wait to see your first launch and landing attempt
This in-depth on the launch pad is great! I think it helps give everyone a greater appreciation for the details and thought that need to go into ALL the aspects of a project like this, not just the complexities and challenges of the rocket itself. Keep up the good work and videos!
I love your videos ! We can see you have great passion talking about your rockets and launch pad !
awesome video as always .... cant wait to see landing test again.
Great stuff - I love the logical, methodical and professional approach on everything you do. Keep up the awesome work!
That was awesome! Love the changes you've made and I'm keen to see how well that conformal coating works out as it seemed quite thin.
So excited for launch and landing attempt!
Awesome! I'm realy lexcited for the new project!
Interested to see how youâre throttling the solid motors!
P.s. Those of you who want a simple flight controller for all your various projects, I just released my code over on my channel :)
Loved the music during the build montage
Very happy that you try landing again!!
Damn dude. This is freaking badass. Iâve always loved this channel and all of your projects have been so fun to watch. Keep it up Joe!
Joey, weâre all behind you. Remember the Boeing axiom ( which they seem to have forgotten) KISS ( Keep It Simple Stupid). Best of luck, you will do well. Donât feel bad, humidity kills Airbus too (Flew A340/A330 for 18 years)
love the lego vibe!
black powder rockets also have a much more interesting exhaust plume, so excited to see them flying!
Nice t see you again rocking it
I have been looking forward to your first rocket landing for so long! Canât wait to see it!
"Overvolt your servos if that's who you are as a person"
That's definitely the kind of person I am. That magic smoke won't release itself!
Well sometimes it does...
Its awesome to hear your giving propulsive landing another go! You've come along way since echo, and I know your going to get it this time. Good luck
Cool video!!! Thanks for sharing đđŸ
Hold-down - two rods of simple solenoids, 180 degrees (or 120 degrees for three) from each other, inserted into 3D printed fuselage attachments with holes for the rods. Solenoid rods pull back into 3D printed enclosure with rods held back until rocket exhaust is no longer a factor. The end of the rods are protected from corrosion by lacquer coating and/or a thin disc of something non-corrosive epoxied to the end of each rod.
Very cool ,inspiring ,and creative ,thanks .
Looks great joe
Wooooow, your projects are progressing a lot!!!
Let's hope this one can land on its feet, I believe in you! :)
Brilliant, looking forward to seeing a launch Jo
*_Great Design Man!_*
1000 / 1000
I LOVED THIS VIDEO. Great footage and descriptions :D :D
Really excited about this one!
It's very cool to see you back in business. đ
Well done Joe, keep it up!
Excited to see some new launches good luck sir
Very good!
Good luck
Great! About the release mechanics, think again: Use a ring with three release points, activated by one servo only. Less is more and also more simultaneous and 3 point is more stable than 4. Cheers.
I love the launch pad. keep up the great work!
AWESOME!! Canât wait until launch!!
This is crazy but I'm looking forward to your videos kinda with the same excitement as the SpaceX ones :D
Looks great, looking forward to seeing it in action
I love all of ur vids
This channel is actually growing at a descent speed
I didn't read all the comments to see if anyone mentioned this, but the new clamp release design looks like it's based upon a very ancient design for a sling trap. You know the kind where you pull a sapling tree over under high tension, with a slipknot loop attached, which is released by stepping on a twig or trip wire. Same concept. Ingenious using it this way. A trick I need to keep in the back of mind anytime I am facing a similar situation. I am an electronics guy, so the mechanical stuff is always lost on me.
Canât wait!
pretty sick man!!!
Hi Joe. Thanks for your fantastic and inspairing job. For hit the pins that are sostaining the clamps I suggest a ring moved for one servo (or two for safety) ensuring that the clamps gave out of the way at the same time every single try. Cheers!
All the best đ€§đ€§đ
I can't stop liking every single video of his!
This is going to be AWESOME!!!
Yay Joe is back!
Great Job
Yess! Another vid đ
The best science channel ever
You are a genius man ! I am building a silo rocket using some of your tip thanks!đ
I like you videos there are so educating
mini elon even looks like young elon xD nice video man!
WHAT?!? THROTTLE CONTROL?!? HOW THE HECC?
YEAH HE CANT JUST SKIP OVER THAT PART, THATS ILLEGAL
@@SHMIDTEY I KNOW RIGHT?!?
I think he just vectors the motor at different rates.
@@levedelson1924 It's an SRE, it can't really throttle. If so, mind explaining?
@@thechanceogden im guessing that means alternating thrust vectors "wastes" thrust slightly in directions other than down. Cosine losses basically.
The red and Yellow do look cool but it also helps identify what moved/didn't move when it should/shouldn't have more easily in playback. You know, when when you start with the Orbital Class rockets. Best of luck with the upcoming flights!
if you run a thin wire (or aluminum foil) under the engine, when it burns through, you could use that as a sensor to tell you the engine has lit and have it release the hold down clamps. (or two tungsten electrodes (TIG rods work well) with a voltage bias and have it measure the plasma from the flame if you want more complicated but more robust). Small weights on the end of the servos to act like wee little hammers could be fun too... (You do have static friction, it is now just easier to address). As always these videos are a whole lot of fun and look forward to the next!
I want to say this, and I hope it doesn't sound wrongly worded, but...
I am so very proud of your work on this channel.
You are inspiring ton of young lives to seek STEM courses and learning and to dream big dreams.
Big huge props to you!
Absolutely awesome update, love the channel though i dont watch it nearly enough
grear person, great launchpad !
A streak of hope in the sky during the year 2020...#joeyisback
You can definitely make covers for the new clamps, with just a slot for the clamps to retract in to. In this way, you use the clamps themselves as the sealing "door" for the cover. Use magnets to secure the covers, and you will be able to take them off easily as well.
Pretty impressed by the new launch pad. And I was really surprised to see how corroded those stainless screws were. Totally insane the damage these engines can dish out.
you can 3D print a housing cover for the servo so you mostly only need to replace the servo arm rather than the entire servo. Think like an open top box where the servo arm protrudes out of a cut out on the side of the box as for your boards you should also 3D print covers for your boards if theyre on the launch pads in general rather than just coating them just for added protection once the rocket clears the platform. Its excess filament but i mean
components add up lol Good work so far!
Don't know if anyone already suggested this, but add a simple thrust/flame detector. Could be something as simple as some thin gauge wire between two probes. When the circuit opens, you know the rocket is lit (regardless of the fuel source) and start a short timer to automatically fire the hold down clamps.
Great video, Joe! I've been following your progress since this past March and have learned much so I've upped my Patreon support for you.
By the way, other great folks in the discord helped direct me with info on the conformal coating for the board; great idea and it's something I will consider for my build. Could you allude as to which conformal coating you're using? I'm "speccing" on Amazon at the moment for some and it looks like there is quite a selection to choose from.
Scott Manley, Joey B, astrum and everyday astronaut? What an awesome day.
Loved the overvolt servo comment. Made my day. Lol
Waiting to see the launch.
It's beautiful.
Yay, a long-ish video of Joe looking positive and the launchpad looking ... cute! (Sorry, but thatâs what you get for the happy colours đ)
Looking forward to the next firing!
Brilliant
@BPS.space The launchpad is looking great, I hope no one will mistake it for a water tower though :P
Looking forward to seeing you try to propulsively land model rockets again!
This is so cool launch pad.
Those new clamps are sluuuuutty
Canât wait
WOW!! Way to go, I can't wait to see it FLY. I've always wondered were you fly your rockets from. I think I'm just right down the road from you, I live 40miles west of Nashville Tn. Congratulation on your Success so far. đđ
If you put a sensor in the flame trench (IR sensor or spring-loaded deflektor plate) the launch pad can detect ignition and only move the clamps when it detects flame or thrust. When using side boosters, this can even prevent lift-off unless all rockets are running.
In my opinion, the deflector plate approach would be more reliable because it doesn't care so much about soot buildup. Simplest way to implement that would be a plate on a long-bladed micro switch with a low spring force.
Another way to implement that would be a pressure transducer in the flame pipe.
Who would imagine that a launch pad would be so interesting đđđ keep it up, brilliant âïž
I would recommend replacing the four motor design with a geared ring with notches on the inside. If you have a ring that goes around the entirety of the clamps and have notches on the inside that would push the pins out of the way, it would allow for a more unified retraction of the clamps. You could use the servo motors to turn the ring, and it would be a cheaper and more simplified design. This launch pad is already really awesome how it is though! Keep up the good work!
Insanely cool bro, keep going.
Oh, time for bells and whistles...
Add 4, one in each corner, led flood lights, to light up that beautiful rocket for those crispy mega cool shots at dusk or even just for display photos at night..
Whatcha think???
Keep it up we dont care about how regularly you upload!
SO glad you decided to resume landing! Very inspiring. My son is attempting to land model rocket like Space X now. Good luck, can't wait to see your landing.
Good luck with your son but thatâs gonna be hard
A thought - I noticed that the posts holding the clamps shut aren't necessarily releasing at the same time which seems like it could be an issue. If the posts were printed attached to a disk parallel to the launch pad, you could use a pair of servos to bump it and all would release at the same time. You'd probably need something slick like PTFE or whatever as a bearing surface for the circular slot that holds it in position but it seems like that could synchronize the release better.
Instead of 4 servos and a bunch of clam pins you could use a bearing ring with notches to hold the clamps and use a single motor to rotate the entire ring. This synchronizes the release of the clamps and makes it easier to inspect and change. Also... single motor ;)
this channel is a good resume for SpaceX
Notification squad!!!đ
Hmmm.....the past launches are the most beautiful launches i have ever seen (i like launches of bps than spacex) i just cant stop imaging the future missions....all the best joe
