I have two recommendations for your firing device: a) Use a guarded pushbutton (EG Grainger P/N 12J255) b) build a circuit to safe it after the button is released so it can't be pressed again until the keyswitch is reset. If you want to get even more extravagant, have a separate low voltage current limited resistance detector that is live when the keyswitch is in the safe position to monitor whether you have a good connection to the igniter, that would light an amber light, and prevent it from arming without that good test (and beep and flash the amber if you try to arm it with an open circuit)

[@Pyrichia]

@@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."

[@organizedfromwithin2525]

@@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.

[@Pyrichia]

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

[@professorg8383]

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!

[@aaroncameron1494]

When connecting the starter at the rocket, use a thick cable with alligator clips to short the signal comming in from the launch control. If there was ever a stuck contact or a capacitive discharge, the energy would be shorted and could prevent an accidental ignition.

[@ac3146]

And a small capacitor to prevent rf sources from causing accidents

[@horusfalcon]

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.

[@TomKappeln]

BINGO ! HF would shortend out also.

[@r.gilman4261]

don't forget induced potentials from AC or RF sources

[@cezarcatalin1406]

How to improve the electrical system: 1.) Add a voltmeter - basic test to see if the battery is still alive and if you have enough voltage to fire the charge. 2.) Add an ohmmeter (if you are planning to use long wires). This is for testing if the wires are too long and if you need a higher voltage for reliable firings. This needs to be disconnected or protected during operation - one does not simply hook up an ohmmeter to an external power supply. 3.) Add a big 4000uF capacitor in parallel with your battery. This does two things: Depending how fast it first charges from the battery, it tells you how much power your battery really has. The main advantage is that it dumps most of the energy stored inside during a discharge, making discharges much more reliable. Remember, a battery can be full but if it’s cold outside it can behave really sluggish - basically functioning at a fraction of it’s designed power. Note: A big capacitor really behaves like a temporary short circuit when connected to a power supply of different voltage - put a big inductor or a resistor between it and the battery. This will extend the life of both the capacitor and the battery. 3.) Add an energy dump tester - basically a variable high power resistor hooked up to a power meter connected to the battery. This literally dumps a load of energy into a big power resistor to see if the circuit can actually deliver and it’s the most direct test and the closest one to the real deal. But it comes at the expense of a bit of energy. Well-built electronic igniters are extremely useful in high power rocketry because you can test everything before the actual ignition.

[@TechIngredients]

In general I agree with your upgrade suggestions, except for the capacitor. Use a well charged battery and don't skimp on the voltage, 12 V is a minimum. The actual energy spent to fire a bridge is a miniscule fraction of the battery's capacity.

As usual, an outstanding video.... Two points I want to share: 1) An additional safety measure is to shunt your wires together to eliminate incidental charge build up at the ignition compound. This ensures risk of ignition is mitigated when you DO NOT want to ignite the compound. 2) The "shelf life" of the Al powder and NH4ClO4 mix is not that long. In other words, make the igniters at the last possible moment before you want to fire them. 24 to 48 hours is typically okay but your mileage will vary on home-brew ignitors...so experimentation is warranted to determine your time intervals and associated confidence levels for good ignition. In short, do not make up a bunch of igniters and expect them to work a year from now.

You are great teachers! Very good camera work and presentation speed!

[@JaenEngineering]

Trained pyrotechnition here. I was always taught, that once you've rigged the pyro (or motor in this case), you ALWAYS cable back from the device to the fire controller. If you're reloading, switch off, remove the key, disconnect and short at the fire controller end. Also, 9-12R, damn that's high! Pro pyro normally meters out at a nominal 2R. Also, the reason we like bridge wires is you can specify the firing current, usually 500mA, and this allows you safely push a 5-10mA continuity test current without the risk of an accidental ignition.

[@TechIngredients]

That is a good point about the cable hook up proceedure. The ohms isn't really an issue as long as the supply voltage is sufficient. Furthermore, a low resistance bridge means you need a proportionally low resistance cable to support the same power deposition in the starter. This requires heavier cables.

[@JaenEngineering]

@@TechIngredients you'd be surprised when it comes to cable gauge. In lovey land (theatre), I've used 0.5-0.75mm2 (22-20 awg) cable on runs well over 25mtrs (75ft) without issue. A 500mA fire current isn't excessive. It's low enough that you don't need high voltages to overcome volt drop along any reasonable cable run, but high enough that you don't need to worry too much about static discharge or, to a lesser degree, emi. That said, if you're designing a system from the ground up, it should be fine, although I will add that I'd recommend the use of actual bridge wires (eg nichome wire) over dipped compounds, as it allows you to get much greater consistency, which if you want to fire several devices (or motors) at once, is important. With consistent current requirements and series wiring it creates an all-go/none-go situation. Something that's very handy you don't want a rocket to go round in circles or worse, come back at you!

There's only a handful of channels I'll stop what I'm doing and watch the new video when I get notified, and this is one.

[@TechIngredients]

Thank you!

One of the best YT channels out there. Thanks.

During my childhood (50 years ago)My early design of sugar rocket igniter was a piece of brillo type steel wool dishwashing scrubber rolled around a bell wire and dipped into gunpowder which is diluted with water to make it like a soft gooey form and dried under the sun, used to ignite with old vacuum tube radio batteries. always worked first attempt, never failed. Good old days.

Wow, I'm impressed, I build my own rockets. Commercially, I can only get E motors, I want to go bigger, and fly higher.. Well done with your explanation of the igniters. Well done.. I get it know.. Good job, love your content!

This video is the perfect way to launch my weekend with a bang.

Living in the Netherlands, (where you can forget buying these products) I absolutely LOVE your videos. I'm 65 and I used to make black powder rockets in South Africa (illegally) but man, if these videos were available in those days, I would have beaten the Mars rovers to Mars. Brilliant indeed.

[@stefanomorandi7150]

this rocket series is awesome! in-depth on both theory and safety, well explained and everything is shown with no time wasted. just awesome! thank you

[@Nemesishk]

You are easily one of the smartest youtubers who does science videos. I love the way you explain the subtle details and particularities of everything you are working with. Very in-depth educational content. You have my subscription and my eternal likes, sir.

[@TechIngredients]

Thanks and welcome!

[@michaelblacktree]

This is arguably the best DIY channel on youtube.

[@BoyceBailey]

T.I. the only channel I go from 2x, to 0.75x, back up a bit and learn again to really make sure I listened.

[@BoyceBailey]

and you get to the end and its the best dad son video on youtoooobe.

[@neilfurby555]

This guy can make anything interesting, superb presentation style.

[@supergeek1418]

Another *EXCELLENT* video. Well done, again.

You really should teach a seminar at PGI. They would love you. I started with Estes rockets in the 60's. Graduated to high power rocketry later in life and now my main hobby is fireworking. The PGI convention is scheduled to take place in Fargo, ND August 7-13. It is definitely a bucket list thing to do. You would fit right in. This was a great video.Thank you sir.

Intro music fits much better than a lot of what I've heard here previously

[@TechIngredients]

Thanks.
