Rocket Ignition System On Steroids! 

Fire in the hole.

LOL

I have risk assessed from a distance and after the fact and believe it would be safer to switch back to having a dead trigger circuit after the initial firing. Even safer if you work in a warehouse.

Yep. That beeping nearly drove me bonkers!

I hope this get's pinned!

Agreed. My one criticism would be lack of clarity in some of the shots. A down camera on a white background cut in for detailed work would be great. E.g. Nile Red

@@VinceDonkovWorks NightHawkInLight is fantastic! Been watching for a very long time now. SmarterEveryday, ElectroBoom, NileRed, Cody's Lab, NurdRage, love them all so, so much!

@@VinceDonkovWorks we all know Nighthawk in light

@@CallMe_DrWorm the king of random for a little fun as well lol

Thanks!

Careful what you're asking for... I had a Science Teacher similar to him who'd regularly involve students in his experiments and every time he asked for a volunteer, we all went i.imgur.com/1ahwClb.gif I for one was part of a static electricity experiment - What happened next would shock you!

If Tech ingredients taught physics/chemistry when I was in school, I might have gone a different direction, or at least retained more. Thank you for your videos

@@TechIngredients this truly is the next advancements of education. And to be sustained on a platform that has other means of garnering ad revenue. It really is the new encyclopedia of information.

Yes - real quality demos, as always on this channel! I did some of this as a little kid. Moved. Wondered about it ever since. I get to see how this is done even though I have no other opportunity for creative interests.

Trust me, the plastic bag weighs -2 grams

You sound experienced.

Him... I would trust.

Well this isn't exactly making meth 101. Either way you might actually blow up lol

🤣

i just needed the tools and materials, didnt need uncle nor grand parent that will show me how ;)

No they don't! I have grand children who are scared of everything. Every time I go to set off a rocket or explosive they run inside and hide.

Really really true.👍

@@alexrXX You're the grandpa they need, not the grandpa they want!

@@bkuker So true.

I love his deadpan expression as the car drove by. They were probably thinking, "the crazy guy is lighting stuff on fire again".

Just had to reply to your comment specifically because you have an NPN transistor for an avatar, and I use a beam power tetrode!

I agree. So many channels make that mistake. Annoying, repetitive background music is just distracting and unnecessary. If you want to listen to background music, you can always add whatever music you like, but it's much harder to remove it, if you don't want it.

Ditto! I despise the usual background music, all too often way too loud, and not contributing to the content.

More like he wants to teach how to get off this planet.

I second that

Google Virgin Galactic

Perhaps the long term plan is to change the earths orbit: TI: "Today, we are going to attempt to alter the orbit of earth with some very powerful rockets we create here in the lab." /joking

@@guytech7310 I don't know about changing the orbit, but getting the Earth's axial tilt regulated would be nice.

Well, it was just the cardboard tube burning at that point.

@@NemoConsequentae Yup. Rigid safety precaution protocols are mostly for people who don't know what they're doing, anyways. Of course you'd always instruct everyone else to follow those precautions because you know how people are, but that doesn't mean you can't take shortcuts when you know your stuff.

@@Baalaaxa Yes, the problems occur when people who don't understand go all, 'monkey see, monkey do' on the shortcuts when the shortcuts are _not_ applicable.

spaceX needs to hire this guy ASAP

Mr Wizard was a kid's show.

No. He is God. He knows everything!

@@alexrXX Close, unlike Somebody, he knows when he _doesn't_ know everything! But then proceeds to figure it out!

@@michiganengineer8621 True! But God is also still figuring out how to make a perfect universe.

@@daithi007 Not really. Guarded pushbuttons are fine for systems that could be activated with a single action accidentally. The keyswitch already prevents that by requiring a separate, different action to arm the system, and you have two indicators showing system state besides. Yet another guard doesn't add to safety in a unique way, it's just redundant. Circuits to disarm on ignition don't make sense either since the igniter has to be replaced, it automatically can't fire again anyway. Low voltage detection is probably impractical or dangerous depending on wire length due to voltage drop, either you can't reliably detect a good circuit, or you have to get the voltage high enough to account for losses and that could cause ignition just from testing. It's a terrible idea to suggest putting electricity through the igniter when it's that electricity that fires it off. There's systems that can do that, but they're not using homemade igniters. Finally, you don't gain safety by checking for open circuits since an open circuit on an igniter fails to a safer condition, which is "no ignition." There's no penalty for pushing the button on a disconnected igniter other than "your rocket doesn't fire."

@@Pyrichia Continuity checking for the rocket igniters has been done safely for decades. Using Kirchhoff's Voltage law and calculating the voltage drop across the relatively small rock igniter resistance compared to the series lamp resistance and using voltage division is how such systems are designed. It's too bad YT does not allow pictures and LaTeX like equations in the comments.

@@organizedfromwithin2525 reminding me of things I should have remembered from other domains; you're right. You can check continuity without setting off an igniter.

So how about mounting it to a base with two spring return key switches 6 feet apart and a momentary contact pish button to fire. The idea is taking two people each holding their switch closed and with one of the remaining hands, pushing the fire button. If you use two buttons in series next to the key switches, a contortionist would have trouble firing it by themselves! You can add in lights like he has in his circuit. Of course you could just pull the ignitor wires and connect to a battery! But if you want to add some drama to your rocket launches, this will do it!

Yes, he is.

This!

Ive never heard of that before, sounds 𝘤𝘰𝘰𝘭. and tough to ignite for sure.

Slowing down of thermal conductivity is hard with these the gel was a good idea

Actually magnesium can also burn with dry ice. Or if you wanna feel REEEEELY nerdy, use CO3! en.wikipedia.org/wiki/Carbon_trioxide Even more violent than those is H2O2m which you can obtain in a [relatively safe] form known as Sodium Percarbonate - en.wikipedia.org/wiki/Sodium_percarbonate Just don't try reacting dry sodium percarbonate with high concentrations of acetic acid ['vinegar' because it produces a highly sensitive explosive, diacetyl peroxide - en.wikipedia.org/wiki/Diacetyl_peroxide

@@DeliciousDeBlair this is not cool. Your comment is what would have probably killed my teenage ass many moons back...

And a small capacitor to prevent rf sources from causing accidents

Your point is well taken, but, with the air gaps in the industrial switches used in this system it's probably not needful. Both the key and the palm button should be OPEN when connecting igniter leads. It would have to be a relatively powerful transmitter to bridge those switches while they are open. Systems I've used in the past had a high resistance continuity lamp circuit which indicated a good igniter connection once the ARM switch is made, but restricted current to levels well below that required for ignition. With such a system, yeah, RFI could be a problem, but not here.

Yes, it’s really nice, especially when it comes to detailed explanation. Check out “Stuff Made Here” and “Applied Science “ as well 👍

😀

he will do thrust measurements

Yes. I'm no expert but it seemed a very long time for such a small motor. Hard to imagine it could produce enough thrust to launch a rocket very high

No nozzles.

The burn rate is slow, as it is pressure dependent. Without a nozzle, the chamber pressure is very low and it burns longer than in a real flight

This is Tech Ingredients. We all know he's going to science and engineer the heck out of these. I'm looking forward to the hybrid engines myself. Possibly using cryo LOX and Perchlorate. Ofr course if you wanted to take us on a guided tour of the book Ignition possibly with a collab with Nile Red that would be really interesting. Incredibly dangerous, but definitly interesting......

BINGO ! HF would shortend out also.

don't forget induced potentials from AC or RF sources

You did mention that.

yeah, funny how he waits with his hand on the key for the flame to go down before shutting the bloody thing off lol

No kidding

MON CANARD EST EN FEU! www.schlockmercenary.com/2005-06-22 I'm also thinking of the gulls on the SpaceX barge during their last attempted landing. (Looks like engine malfunction during reentry burn, missed it entirely.) Lucky gulls...

Professor for sure he is...and NASA, that was also my thought.

Well , I'm betting 3m or some company similar .

This is why i stick with my "old" Colts and Remingtons.

Extremely dangerous fabrication. I think Cody's Lab made one long ago, but probably he had to take it down somewhere along the line.

I just recently saw a YT video on that subject.

@@benthere8051 with elvis ammo?! He's got a great channel! They should collaborate

Pictxels

Oh dear Brian. I do hope you’ve recovered

aka IEEE1394. For a while "firewire" wasn't used, and IEEE 1394 used, instead. This was partially because a fancy speaker wire company (like Monster Cable, but don't recall which one) was using it as a trademark. The two businesses were too close together, in category, so the data protocol vendors, just avoided the name.

Firewire from back in the day. You have a webcam that supports Firewire? It's not like any of those cameras of that era needed that kind of bandwidth. Power hungry, somewhat flaky protocol.

Good luck.

You're welcome and thank you!

Thank you!
