THANKS ROB

"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!

This channel is like the greatest rocket documentary ever

Now the tough choices - aquafina or dasani water tower for acoustic suppression

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

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

This is so cool I can’t wait to see it launch and then land. Best of luck

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.

"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 🤔

I never skip the KZfaq advertisement in this channel....to support BPS ❤️

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!

missed these High Quality videos; good to see you back. Can't wait to see your first launch and landing attempt

I’m so hype for this up coming project best of luck to you. Happy to see another video❤️

Loved the music during the build montage

So excited for launch and landing attempt!

Very happy that you try landing again!!

Awesome! I'm realy lexcited for the new project!

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.

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!

love the lego vibe! black powder rockets also have a much more interesting exhaust plume, so excited to see them flying!

I love your videos ! We can see you have great passion talking about your rockets and launch pad !

Nice t see you again rocking it

Interested to see how you’re 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 :)

I have been looking forward to your first rocket landing for so long! Can’t wait to see it!

Damn dude. This is freaking badass. I’ve always loved this channel and all of your projects have been so fun to watch. Keep it up Joe!

AWESOME!! Can’t wait until launch!!

It's very cool to see you back in business. 🚀

Really excited about this one!

Wooooow, your projects are progressing a lot!!! Let's hope this one can land on its feet, I believe in you! :)

Cool video!!! Thanks for sharing 👍🏾

Very cool ,inspiring ,and creative ,thanks .

This channel is actually growing at a descent speed

Brilliant, looking forward to seeing a launch Jo

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.

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

Excited to see some new launches good luck sir

Looks great joe

Well done Joe, keep it up!

"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!

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.

Looks great, looking forward to seeing it in action

Can’t wait!

1000 / 1000 I LOVED THIS VIDEO. Great footage and descriptions :D :D

*_Great Design Man!_*

All the best 🤧🤧🚀

Joey, we’re 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. Don’t feel bad, humidity kills Airbus too (Flew A340/A330 for 18 years)

This is crazy but I'm looking forward to your videos kinda with the same excitement as the SpaceX ones :D

Yay Joe is back!

I can't stop liking every single video of his!

Great Job

pretty sick man!!!

A streak of hope in the sky during the year 2020...#joeyisback

I love the launch pad. keep up the great work!

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!

WHAT?!? THROTTLE CONTROL?!? HOW THE HECC?

The best science channel ever

This is going to be AWESOME!!!

I love all of ur vids

Yess! Another vid 😄

Those new clamps are sluuuuutty

mini elon even looks like young elon xD nice video man!

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.

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.

Yay, a long-ish video of Joe looking positive and the launchpad looking ... cute! (Sorry, but that’s what you get for the happy colours 😛) Looking forward to the next firing!

Loved the overvolt servo comment. Made my day. Lol

You are a genius man ! I am building a silo rocket using some of your tip thanks!😄

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!

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!

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!

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.

grear person, great launchpad !

Waiting to see the launch.

Absolutely awesome update, love the channel though i dont watch it nearly enough

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.

Brilliant

I like you videos there are so educating

Can’t wait

Nice...May your sky be blue...!!!

Keep it up we dont care about how regularly you upload!

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

@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!

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???

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!

this channel is a good resume for SpaceX

This is so cool launch pad.

It's beautiful.

BPS is back

*it's getting real*

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. 🚀🚀

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!

Missed your stuff

Congratulations on your improvements!!!! Rocket on Rocketman!!!

Looks cool and is cool and how did you get throttle control

Awesome to see you are looking at the launch pad for gyro calibration are you looking at vibration on the lunch pad it's self??

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.
