Words can't express how utterly amazing inspirational and inspiring these videos are it is quite fantastic what you have done and it can't be overstated. Thanks so much for all your hard work and keep it up all the best.
Good job. +1 subscriber. I will say based on what I know of supersonic flight transitions, if you ever intend to make this project supersonic, the proximity of the long fixed body fins to the articulating fins in back may prevent the articulating fins from 'grabbing' much air for maneuvering as the shock cones from the body fins will create 4 localized regions of low pressure around all of the movable surfaces because all 8 fins directly aligned fore and aft. Using grid fins in the back would fix this at the cost of subsonic efficiency, or maybe moving the body fins more forward on the rocket body. I wouldn't suggest rotating the body fins to be off axis because this would increase the drag and would put the back fins in line with shock cone paths, but this option might be better for subsonic only maneuvering. Look forward to seeing more of your videos. 👍
What about the articulating fins seamlessly connecting with the fixed ones such that when aligned with the main body axis (z axis?) it forms one seamless fin (or negligible gap between them)? Would the low-pressure pockets still have an impact in that case? I don't know much about airflow dynamics but it seems like its probably a low pressure "cone" so as you get closer to the source you'd have to articulate less to eliminate the offset? Just curious.
@@laytonmiller5865 In my mindsim (thinking about it for 3 seconds), the closeness to the source of the sonic boom would hurt the controls, not help. It could go either way I guess, but the turbulence coming from the fin's leading edge would probably get more manageable the farther away from the leading edge you go. I think that either way, active controlled fins for supersonic flights is a bad idea. The single point of contact would have to be very strong, adding weight and drag. Then again, we do it for fun so who cares about performance.
That's why you distort the rocket body as the control surface in supersonic flight! Requires proper Reynold's numbers modeling in a wind tunnel. Just 2 cents. Think of "Flight of the Navigator", 1986. Party On!!!🎉🎉🎉❤🎉🎉🎉
Good shit bro, this stuff is like a better version of what Joe Barnard was doing a couple years ago. That board is beautiful! There's a guy on the rocketry forum that cuts holes in the bottom of his body tubes to add to the base drag, his rockets fly stable with no fins and no active control, but they are inefficient due to the high drag. Rockets like that are really fun especially since the FAA waivers are low where I live, so I want to get into active control to spice things up. This is not a tutorial, contrary to what everyone yapping in the comments thinks, but it is a good resource with lots of good ideas that will simplify the engineering design process for people like me who would otherwise have to build the know-how from scratch. You could have kept your solutions a secret, but you shared it with everyone, thus making this part of the hobby slightly easier to get into. Thanks!
i have always wanted to become an electronics engineer or aeronautical engineer but i was not smart enough , damn your work is so impresive . Alot of respect
Crazy to see how far DIY has come that whole rocket project is just incredible. Really good work. I would be carefull not to show too much since I dont know how the government reacts to something like this. I think in many countries this can be problematic. Anyway I hope to see more from this project its just to cool.
Perfect to put under the wings of that massive fiberglass drone I was thinking of building, with this I can either get a scholarship to MIT, a job offer at Raytheon, or a nice and comfy spot of "the list".
Fun fact: you can’t send guidance data of any sort to the rocket in flight because that suddenly turns it into a guided missile. The FAA isn’t too happy about that. Edit: there's a difference between an internal guidance system for maneuvers made for the rocket, by the rocket, and externally choosing its direction from a controller. Missiles don't need a warhead to be a missile, and they can be tiny. Plus a supersonic dart does a lot more damage than a drone on Ebay which is why these are all legal, minus the missile aspect.
Is that true? So the FAA rather has uncontrolled probably malfuntioning aircrafts in the air? I mean a RC Plane can be controlled, or are there other restrictions that apply?
@@einhalbesbrot RC vehicles are different than what are essentially recoverable missiles. The internal guidance of the rocket can work, but any active external commands are NOT a good idea. You could use a tiny model rocket to hit something flying 5000’ up easily, and if you made it bigger and guided it (like a lot of later steps in the hobby), you could hit things at 20000’ or up.
@@judet2992 but there must be some form of internal guidance. A self correcting "fire and forget" rocket must be worse. But then again its rules and regulations, they dont have to make sense. Here in germany there is a bunch of weird rules.all different for drones, helicopters, rc planes, rc gliders.
So sweet man this is excellent work. So cool. why not multiplex your signal lines ex: single wire PPM for your multiple pwm channels. Or better i2c (wire.h), address different stages/sections with a small microcontroller slave, connected to corresponding actuators. all receiving data from a single i2c bus from the master avionics stack. This way you don’t really need more than 4 wires in the raceway.
If he doesn’t need to receive data back from the lower modules then just using uart and only using the TX line on the main controller would work, just connect it to the RX line of the slave microcontrollers since they can all receive without interfering with each other, just start the data packet with an address. Then you only need three wires.
Great video and love the detail you are going into. As someone getting into model rocketry I love channels like yours. What kind of motors are you using in these builds?
Thumbs up ! Proper work - from the rocket to the software to the test processed or to say from A to Z! I am deeply impressed!!! Never saw such a proper work ! (BTW how do you measure current? Can you give me a clue?)
nice stacked build. i been using teensy 4.1 and custom 915mhz in similar hard realtime use, but wow the 3d print fits are so nice with cots nightmare footprints
im sure you know this exists but if not its handy stuff. there is heat shrink that is adhesive lined and heat activated. can make any soldered assembly pretty resilient.
The rollerons used in sidewinder missiles need to be spun up in order to work correctly. Sidewinders are launched while already in motion so the rollerons have been spun up prior to launch. I'm pretty sure there's a minimum airspeed required when launching a sidewinder since it the missile needs the speed to spin up the rollerons. A sidewinder launched from zero airspeed loses the benefit the rollerons would normally provide. Digital IMU technology has come far enough that it makes more sense to use the digital sensors. I personally think rollerons are super cool. I just don't think they're appropriate for this application.
@@ddegn The MIM-72 Chapparal was a SAM that used Sidewinder missiles and entered service in 1969 and phased out in 1998. I think the initial launch, because it won’t have to do crazy off bore-sight maneuvers, would give them the spin up needed.
Rollerons solved the roll instability problems the early missiles had with canards. I have built canard controlled rockets in the past (without rollerons) and had similar issues. This rocket uses aft fin control, so I have to worry less about roll reversal and changes to the roll control dynamics throughout flight. Other folks like Jim Jarvis use canards, but let their entire aft fin assembly spin freely about the rocket's long axis to solve the problem. Spinning fin cans seems to work well, and are used on a number of missiles like GMLRS and the Excalibur guided artillery ammunition.
100% great video but to help speed up the fun alignment you can 3D print a cap with slits and program it to "calibrate" by wiggling them back and forth until a resistance is detected (fit into the slits) and set that as a the aligned position
Wish this was in anyway legal to do outside of like in a university or something where I live 😢 there is barely any rocketry hobbyists here I'm ireland ,as someone who builds and flies fpv quads I'm pretty at home watching this too lots of similar components and I'll have to watch how you designed the pcb ,nice work on the build man.
We need to start a go fund me to buy this guy a deserted island with a volcano on it so he can fulfill his potential of being a class A Bond villain. This is one of the greatest compliments I can pay a person. Kudos!
You should try and get a pi into leo. A couple of high res cam modules and some reaction wheels, some photovoltaics, a bigger fuel tank and engine, and you'd have your own orbital telescope.
Some rocket systems use a piston that’s driven pneumatically to physically push the rocket out of the tube and then the booster rocket kicks in fires it then might help you get a little bit more speed or flight time because it takes a lot of thrust getting the rocket to go from zero to plaid
Be careful not to violate ITARs, guided rocket technology can be classified as munitions under it, so be sure not to violate any laws. Otherwise, looks great!
Dear FBI agent, i only clicked in this video for hobby and education purposes. I would never think of making one of these things to hit something and explode. Thank you for your care over me. Edit: Blud, im muslim but i ain't going to no towers with it, nor scream alahu akbar and shoot it...
If you end up having issues with the wireless telemetry downlink, it might be worth getting a different antenna or orienting the existing antenna differently. Currently, the antenna dead-spot will be pointing straight downwards = basically where your launch site and presumably receiver antenna will be located.
The missile knows where it is at all times. It knows this because it knows where it isn't, by subtracting where it is, from where it isn't, or where it isn't, from where it is, whichever is greater, it obtains a difference, or deviation. The guidance sub-system uses deviations to generate corrective commands to drive the missile from a position where it is, to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position where it was, is now the position that it isn't. In the event of the position that it is in is not the position that it wasn't, the system has required a variation. The variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too, may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computance scenario works as follows: Because a variation has modified some of the information the missile has obtained, it is not sure just where it is, however it is sure where it isn't, within reason, and it knows where it was. It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum og where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "air"
What? Essentially, the GPS receiver measures the distance to each satellite by the amount of time it takes to receive a transmitted signal. With distance measurements from a few more satellites, the receiver can determine a user's position. I can see the GPS device he installed.
@@ClickClack_BamHe copy pasted an early engineering meme from a video from back in the day. It basically is describing a Proportional Integral Derivative (PID) loop to control the missile's course, just in an funny obtuse way. The GPS would be the position sensor in this case.
These would be perfect missiles for shooting down drones, cheap and could be massed produced. Just some modification to make them more suited for military use. You can carry them around in portable packs, and as far were you would get the targeting data, maybe from ground or air based infrared sensors or radar.
Could you make a video talking about the software aspect of the project? How you built the dashboard and code for the rocket too, would be really cool to learn!
I'd love to learn more about the camera system. I notice they are FPV drone cameras, but are they digital or analog, and do they record and save data on their own (meaning do you just have to power them, and their built in electronics handle everything to get you a video file)? Looking into options for cameras for both rockets and cars. Thanks!
That would actually be MUCH harder than what he doing now. His current project is GPS/camera based. For an anti-air rocket, it needs to be radar or IR guided. That introduces MASSIVE issues to be overcome on a NON multimillion dollar project. For example, a current sidewinder IR missile has an actively cooled seeker head, using liquid nitrogen...
@@sorryociffer IR sensors are need to be cooled to do their job properly. Radar modules have come down in price incredibly in the last few years, which would make them an easily obtainable item. I also think I remember Lafayette Systems saying something along the lines of "Not including a guidance system because that would be crossing the line and I might get shut down". But I may be thinking about different channel... ;)
@@pompeymonkey3271 Radar modules that are available to a random dude are hobbyist level at best and worthless for this application. IR is also too complex and both would fall prey to countermeasures easily.
@@sorryociffer this makes his model rocket capable of working as a gmlrs (guided multiple launch rocket system) capable to land attack like the himar with imaging cameras for terminal guidance 😂 Gotta be badass

Some rocket systems use a piston that’s driven pneumatically to physically push the rocket out of the tube and then the booster rocket kicks in fires it then might help you get a little bit more speed or flight time because it takes a lot of thrust getting the rocket to go from zero to plaid
Bro, please make a video about how to code that Telemetry GUI you made
Be careful not to violate ITARs, guided rocket technology can be classified as munitions under it, so be sure not to violate any laws.
Otherwise, looks great!
Definitely interested in the PCB creation process. Hopefully you can go over your logic for the decisions, even if some are just best guesses.
Dear FBI agent, i only clicked in this video for hobby and education purposes. I would never think of making one of these things to hit something and explode. Thank you for your care over me.
Edit: Blud, im muslim but i ain't going to no towers with it, nor scream alahu akbar and shoot it...
The schizophrenia is strong with this one
You are being investigated right now. Please just tells us where you live and make our work easier. You'll spend just a couple of years in Guantanamo!
😂
I would.
FBI OPEN THE DOOR!!!!
Impressive job! Suscribed!
Okay, this is awesome. Instant sub
If you end up having issues with the wireless telemetry downlink, it might be worth getting a different antenna or orienting the existing antenna differently. Currently, the antenna dead-spot will be pointing straight downwards = basically where your launch site and presumably receiver antenna will be located.
Офигенная работа. Браво.
Impressive! Great job!!!!
The missile knows where it is at all times. It knows this because it knows where it isn't, by subtracting where it is, from where it isn't, or where it isn't, from where it is, whichever is greater, it obtains a difference, or deviation. The guidance sub-system uses deviations to generate corrective commands to drive the missile from a position where it is, to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position where it was, is now the position that it isn't. In the event of the position that it is in is not the position that it wasn't, the system has required a variation. The variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too, may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computance scenario works as follows: Because a variation has modified some of the information the missile has obtained, it is not sure just where it is, however it is sure where it isn't, within reason, and it knows where it was. It now subracts where it should be, from where it wasn't, or vice versa. By differentiating this from the algebraic sum og where it shouldn't be, and where it was. It is able to obtain a deviation, and a variation, which is called "air"
What?
Essentially, the GPS receiver measures the distance to each satellite by the amount of time it takes to receive a transmitted signal. With distance measurements from a few more satellites, the receiver can determine a user's position.
I can see the GPS device he installed.
@@ClickClack_BamHe copy pasted an early engineering meme from a video from back in the day. It basically is describing a Proportional Integral Derivative (PID) loop to control the missile's course, just in an funny obtuse way. The GPS would be the position sensor in this case.
These would be perfect missiles for shooting down drones, cheap and could be massed produced. Just some modification to make them more suited for military use. You can carry them around in portable packs, and as far were you would get the targeting data, maybe from ground or air based infrared sensors or radar.
Ah, finally! A missile that knows where it is!
Bro. Next level
This is so good!
This is extremely impressive. Would love to see the details. Are you planning to make this open source, or share in any way?
US laws prevent the sharing of potentially dangerous software/hardware designs, refer to last video for confirmation from OP
Thx for the info , now I will put a warhead 🤓
Could you make a video talking about the software aspect of the project? How you built the dashboard and code for the rocket too, would be really cool to learn!
Dude got skills.
I'd love to learn more about the camera system. I notice they are FPV drone cameras, but are they digital or analog, and do they record and save data on their own (meaning do you just have to power them, and their built in electronics handle everything to get you a video file)? Looking into options for cameras for both rockets and cars. Thanks!
Are you building a model rocket or a model anti-air rocket?🔥
That would actually be MUCH harder than what he doing now. His current project is GPS/camera based. For an anti-air rocket, it needs to be radar or IR guided. That introduces MASSIVE issues to be overcome on a NON multimillion dollar project. For example, a current sidewinder IR missile has an actively cooled seeker head, using liquid nitrogen...
@@sorryociffer IR sensors are need to be cooled to do their job properly. Radar modules have come down in price incredibly in the last few years, which would make them an easily obtainable item.
I also think I remember Lafayette Systems saying something along the lines of "Not including a guidance system because that would be crossing the line and I might get shut down". But I may be thinking about different channel... ;)
@@pompeymonkey3271 Radar modules that are available to a random dude are hobbyist level at best and worthless for this application. IR is also too complex and both would fall prey to countermeasures easily.
Anti Deez nuts🚀🥜🫥
@@sorryociffer this makes his model rocket capable of working as a gmlrs (guided multiple launch rocket system) capable to land attack like the himar with imaging cameras for terminal guidance 😂
Gotta be badass
