Preparing Our DIY Rockets For Testing!

[@beanhole69]

Love this channel. No BS drama. No BS virtue signaling. No narcissism. Just science with a smidge of humor and a ton of fun.

[@TechIngredients]

Thanks!

[@MrFaaaaaaaaaaaaaaaaa]

the very act of accusing someone (or in this case, not) of virtue signalling is an act of virtue signalling in itself and its overuse as an ad hominem attack during political debate has rendered it a meaningless political buzzword

I'd be inviting the neighbours over to watch and experience these tests.. get them onboard and excited about it, less likely they'll call the cops and get you shut down.. I wish I could play with rockets like this here in Australia, but sadly the most explosive thing we can legally get hold of, is a packet of sparklers.. (but even, there's ways to bump this up to something a little more impressive..) shhh, don't tell the thought police.. 😁

This is just so wholesome. There's something really psychologically calming in knowing that you've taken all of the necessary safety precautions.

Now that you have a load cell incorporated, I would love to see the thrust difference between your homemade hybrid and solid fuel engines with a similar size and nozzle configuration. In the future adding the data from temperature and sound will also be interesting.

Absolutely. Seeing the thrust comparison between solid and hybrid motors would be great. Even better if we eventually get to see totally self contained hybrids and can see the differences in thrust:weight ratios.

[@Rattus79]

You remind me of my Grandfather. He was an engineer, and his attention to detail and yours are just so similar. I remember going out to his shed as a kid. It always had the best toys. He got a bunch of one armed bandits (old school poker machines) from the dump one time. He pulled them apart for the stepper motors (rare/expensive back in the late 80's) and made a centipede robot. Another time, he made a working electric guitar for a class project I was working on. Still only got a B... Anyways, Thank you so much for what you do. I love your teaching style, which so closely reflects how I best learn.

And this point it would be neat to see you also make a control computer that would automate the entire countdown process, and stop if anything falls.

[@SolarWebsite]

Yeah, that was what I thought. A Raspberry Pi or even an ESP32 would have more than enough power and GPIO pins to do that.

[@jonathanm9436]

With all of the solenoids present, it's a small step to full automation. Although, I think, having everything 'manual' is part of the education process. Also if shit goes west, it might be easier to stop on any one of the steps. That said, a BRB (big red button) would solve that too.

I am amazed by how thorough and dedicated you are. Please stay that way and don't get convinced to "quickly" produce flashy prototypes to increase the number views on your videos. IMO the most important lecture you are giving in your videos is not about the actual subject itself, but rather about your scientific methodology. Very good job!

@@TechIngredients in the larger systems I'm more familiar with, I know during the entire countdown (approx 15mins before launch and after flight systems give a full go for launch), there are a whole process if events from control handoff to the internal flight computer, to the ignition stack process. Was not aware that hybrids were more than just push button activation. I'd be curious to see if, with a ras-pi and some solenoids, if you couldn't automate a large part of this process leading up to launch....

[@Ts6451]

I never really thought of how such a hybrid engine would be lit up, but if I did, I would probably have assumed that you would coat the fuel with something more easily ignited, or perhaps have a thin coating of fuel/oxidizer mixture tuned to give the desired characteristics.

I am a little surprised that you have not computerised the start up sequence, automating the switching of the various components.

[@bobby_greene]

Maybe with a Deadman switch to make it easy to abort at any point

[@Ithirahad]

Probably because it's a work in progress and so far, their ignition sequence doesn't have very many steps. If this was a full-scale rocket with a mess of purge valves to open and close, and pneumatic/hydraulic systems to pressurize, and monitor sensors to turn on, and flight computers to arm, and a hundred other things, automating would make sense.

[@nigeljohnson9820]

@@Ithirahad one of the advantages of an automated sequence is that it reduces the possibility of human error. If more sensors are added, it may be necessary to automate. It can be difficult to computerising a diverse number of interfaces, such as the high speed camera, as a simple on/off input may not be available. Cable management becomes a problem, as more devices are added, and maybe some sort of data bus will be required, with distributed computing to handle the the bus data bottleneck.

[@Ithirahad]

@@nigeljohnson9820 Exactly; it seems like a good idea on paper but there are major technical challenges associated with automating. It gives more consistent results, sure, but trying to get all of the equipment to work together on an automated sequence is probably worthy of a long video series of its own. Probably not the sorts of decisions you want to make while so much stuff is still in flux.

[@nigeljohnson9820]

@@Ithirahad it is certainly a big project in its one right. I agree it is not practical while still experimenting, as it could be very wasteful. Potentially it could enhance safety, by implementing a number of interlocks. I can see the problems, such as adjusting the NOx release to occur after the was has ignited. It will not solve the problem of ensuring the manual oxygen and NOx tank master valves are in the correct position.
