It's quite fascinating that currently we have resources available for the general public to build a rocket brain like this :D Imagine doing that in 1950's
Back in the 2000's there was a guy in New Zealand who built a pulse-jet rocket using only parts ordered online. Supposedly it would fly up to 160km and deliver a 10kg "package". Apparently this guy took part in a British TV show called Scrapheap Challenge. He constructed a working pulse-jet out of scrap in about 10 hours. It was then attached to a kart that got up to 64km/h
@@ralphm6901 a pulse jet is the most basic form of jet engine anyone can make one you literally just bend a metal pipe into a long u shape and a fuel source in the middle
@@BobaPhettamine It's also easy to make a torch using a lighter and a Febreze can, doesn't mean it will perform as well as an oxyacetylene kit. A pulse jet that can reach 64km/h and a whole *Switzerland* worth of range is nothing to sneeze at.
The safety culture that armature rocketeers keep is really awesome. It reminds me of what the RC multirotor hobby was like before the uneducated got hold of drones from DJI and other companies, and governments quickly banned everything. That safety culture will keep the hobby alive and thriving for as long as it is maintained. You guys are awesome!
I agree that people fly where they aren't supposed to and that has caused a *ton* of issues for those of us who practice proper safety. But it's worth mentioning that not everything was perfect before the DJI influx. RC hardware and software has gotten sooo much better, safety-wise in the last few years. I remember a bunch of runaways, wrongly set failsafe modes with never to be seen again equipment, just straight up bugs in esc software, burning drones and whatnot. All the old timers that I know fly without prearm switches and even mentioning it gets met with scepticism. Some hand-launch or even hand-land their drones. It's just a hobby that tends to attract slightly insane people 😂
Excellent book. My area only covers a single chapter in this book. It does an excellent job of describing the fundamentals of ....something, but there is a LOT more that goes into that particular system and "how the sausage is really made".
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 subsystem 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 that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired 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 computer 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 subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
@@kiq4767 that's what I was implying. They know he can build this shit, so either accept a lockheed martin job offer, or spontaneously go on an extended vacation/impromptu "retirement"
In Germany for example, building an amateur rocket with any kind of control mechanism able to actively modify the flight path is illegal, and you'd get into very serious trouble for it (possibly jail time), because it's considered military weapons technology here. Kudos for including that section on laws and safety at the end of the video!
Anything sideways you'll have people at your door. Straight up and you can do some neat stuff without too many issues, assuming you clear everything with FFA above a certain level. I think it's sad that it's not encouraged in a safe manner. There's so much to be learned by tests like this
Actually the video is wrong in that regard. I know he said he checked multiple times, but there's this little thing called the USML, a part of the federal code of regulations. Normal model rockets are exempt from this because they rely on passive stability to maintain flight and are made of lightweight materials therefore are not a guided missile as defined within 22 CFR Part 121.1, category IV. The exclusion note specifically says model rockets shall not contain active control i.e. RF/GPS/etc. I work in aerospace for a living and we must abide by both ITAR for export purposes but also the USML as a categorical definition.
not at all. nothing state of the art about this. this is actually very archaic tech compared to what is current state of the art. We've had more advanced rocketry and missiles back in WW2.
Fins are incredibly difficult to use for rocket guidance because they give you an enormous power of steering in all axis. 1 degree off and your rocket will break under the high g forces… This rocket is a masterpiece!
17:25 I was just going to say it looked like it had an infill structure! Getting into 3d printing and I love rockets. I am looking into integrating the Aim 9 sidewinder fin wheels gyroscopic correction system into a model.
You and BPS Space need to talk, he’s building up to a space shot, some of your R&D would probably be useful. Also please post some sort of articles for fellow amateurs to implement and understand what you have built, please. I’d love to understand the electronics and code side of this better to basically do the same thing but with side mounted cameras. Not saying share code btw just understanding concepts and software language better in context to these sorts of things.
My favorite part of your projects, especially compared to others, is that you are repeating the flights to some degree. For example the self-land projects all seem to never fly after the first successful landing. So I'm really glad to see you reach an objective then set a new related goal and keep flying that concept.

Years ago and in another life, this would require an inertial navigation system so heavy this rocket could not lift it. Then MEMS systems get better and better and better as well as available to nearly anyone. Plus they weigh very little and a few other good things. Cool to see someone playing around and seeing whats possible. All the sam, mind your P's and Q's or the wrong people will take notice.
i allways thought there was a reaons for youtube rockets to go only go up, i think youre reaaallyyy pushing the limit here, i love it i'm downloading this
Do you think it could be helpful to check at the transition of Launch-Dir-Hold to Waypoint whether the angle or resulting force between the current trajectory and the predicted trajectory would exceed a threshold for safe maneuver?
"I am not supplying code, cad or PCB files for this project." BORING how else am I supposed to make ballistic weapons that can hit a fly a continent away????? Fund my own researchers???? Cringe.
You’ve done an impressive job on this! In the olden days, there was a design called the Sun Seeker, which used a photocell to aim generally “up.” Not sophisticated, but it was in reach for amateurs with a soldering iron.
Could you program the Abort Euler to activate after a certain time or distance traveled at various bank angles? Have the distance or time vary based on the severity of the bank angle and you can keep the rocket traveling straight up within a predetermined cylinder... which may be tilted or skewed, but would provide a safety margin that could be mapped in 3D space but allow the rocket to move around within that space as needed.
Wait.... Are you saying the US State department & Pentagon In all actuality DO NOT sit at their desks watching BPS Space & Lafayette Systems UA-cam 🚀🚀 videos!? 😁😁😜😜😜
And many advanced technologies will not let you know. Just like Snowden's PRISM , it is basically impossible for you to know if it is not exposed. This is just nothing Intellectual freedom is not actually free, and is not freedom of speech.
Why did you choose to go for carbon fibre PC for that connection point on the avionics assembly? Adding fibre to a filament makes it stiffer but makes it slightly weaker and more brittle/lower impact resistance. For that piece you want a material with high strength and impact strength, but stiffness isn’t important from what I can see. Something like a TPU or polypropylene would likely be better here with polypropylene likely being the better choice although it is difficult to print.
At time 7:27 accidental is misspelled…just minor thing. Love the full video, description, etc. What you have accomplished is what we dreamed of 60+ yrs ago…back when red one transistor radios with a white wired earpiece. to hear Sputnik beeps as it passed overhead.
Holy crap I did not know you could casually just put step by step instructions on building a homemade guided missile on youtube and not get disappeared
I was at Muncie,on 4th flight,I have your video on my ch. Cool stuff back in the day we couldn't have Guidance due to 911. I'd love to print your rocket for my fun.
Why not have an IAS sensor to tune the control loop in function of the airspeed and also detect optimal parachute deployment? It looks like your rocket deploys before apogee, but i might be wrong
Looks like flight 5 might have actually worked quite well too if the pitch limit hadn't kicked in. I wonder if that limit could be relaxed above some minimum altitude? After all, the higher pitch only becomes necessary if the rocket is already quite high.
Yeah I think flight 5 would have gotten pretty close! I may relax the pitch limit a bit. I think the limiting factor is being able to pitch up to vertical after reaching the waypoint. If it reaches the waypoint going horizontal, the rocket may not have enough energy to do that pitch-up. This is a hugely limiting factor and really restricts the types of maneuver I can do with this small rocket. I’ll need to go higher and faster to really get into the fancy maneuver profiles.
put a photovoltaic sensor on the rocket body and point a laser to a know position in space so that its pierce point is on the waypoint trajectory. reference the simulated reference(from flight controller) to the triggered results detected from the laser. collect enough resulting differences at different positions to calculate the range of certainty. awesome build.
You have a Cool Channel and Project. I love those *_DIGI XBee radio Modems,_* I used a lot of the Digi modems, I started using them back when they were still called *_Maxstream_* long before Digi bought them. I used the frequency hopping spread spectrum, the direct sequence spread spectrum and the XBee. But I like the 900 MHz direct sequence the best. I used them the on my UAV's for the control links and data down links. On one trip to Australia while we were conducting test for the Australian Outback Rescue, we tracked one of our UAV’s over *_20 kilometers_* using a pair of one Watt 900 MHz Digi direct sequence spread spectrum modems. We were the first team to fly into and come back from the Outback Rescue search area. I used the direct sequence spread spectrum modems on my redundant spread spectrum R.C. link. I could configure a redundant system for *_900 MHz or 2.4 GHz or a combination of both 900 and 2.4._* I had the same issue the *_ITAR police,_* I was doing this in the late 1990's to mid 2000's I had all kinds of visitors from all kinds of 3 letter agencies. This was long before most people knew what a UAV or a drone was and I would get reported to these agencies on a regular basis. At first it was scary but after a while it became a pain in the ASS.
Instead of printing parts at 100% infill, print them with 99 walls (obviously that many walls won't actually print) - walls provide strength along the axis you need for the application of chute line anchor.
People in the 90s: its rocket science. People in 2024: here is a youtube video about rocked guidance, open to the public, for free. Made by an amateur.
Might sound dumb but could you install a edf fan in the rocket inplace of the rocket motor then you could have near unlimited test flights . Would probly need a contra rotating edf to cancel out the torque of the motors
Congrats!!! 1. You could put 2 or 3 waypoints on each flight to gather more data. 2. How precise is your measuring system of actual path and how it works?
Are you using PID's? The wobble in the roll suggests overshooting caused by large gains. It would be useful to tune these systems a bit more, but you may even need to apply another factor on all the modifiers depending on what air speed you have which is changing the control strength.
You should setup an algorithm verification pipeline which tests the control sw in sim everytime you make a change. It is a bit more work in the beginning but will pay thicc dividends in the end. Cheers!
Random idea but maybe for the silo have it jettisoned out in a manner similar to what destroyers have. There's the initial launch to get it out of the tube then the rockets ignition kicks in to prevent damage to the tube. That may resolve the problem of wrecking it.
Damn I love your videos so much Pls keep it up btw, the AIM-9s have a control system, which are increaseing their control athority step by step after launch. Seems lke a good idea for Diamond-X as well
You can do the same with a gyro. in fact that's how Autopilot works in some aircraft. Also you could make this a radar guided system using tracking software connected to the control system.
Why don't model rocket makers use counter rotating blades that fold down, along the rocket body while under thrust but fold out (and spin) when the rocket is coming back down instead of using parachutes to control the rocket's descent?
We have been making "video" guided rockets and drones for the past 9 years using both visual and IR cameras and combined the two recently. No gps or rf jammers to worry about. 😂😂 I'm currently working on a multiple spectrum system now that combines many different spectrums to make them even more fail safe. 😊
Just my opinion, but I feel like a thin metal washer fixed to either side of the parachute attachment point on the wishbone with an adhesive would go a long way in limiting the risk of the 3D printed material failing when it experiences that big shock load.

The ATF: *KNOCK KNOCK*
ATF? fuck try DOD, DOJ, DHS, FBI, US Department of State. All of them will sending hit squads, sorry, sorry... officers to execute search warrants.
Do you think it could be helpful to check at the transition of Launch-Dir-Hold to Waypoint whether the angle or resulting force between the current trajectory and the predicted trajectory would exceed a threshold for safe maneuver?
"I am not supplying code, cad or PCB files for this project." BORING how else am I supposed to make ballistic weapons that can hit a fly a continent away????? Fund my own researchers???? Cringe.
This is a company’s UA-cam channels
😂😂agreed
He does not want to commit an ITAR export violation.

You’ve done an impressive job on this! In the olden days, there was a design called the Sun Seeker, which used a photocell to aim generally “up.” Not sophisticated, but it was in reach for amateurs with a soldering iron.
Thanks!
It's good he called it "Waypoints" not "Targets"
Waypoint is stationary. Targets is another objective but will come later in this series.
Thanks for the tutorial! I'll go build a guided missle right now.
Could you program the Abort Euler to activate after a certain time or distance traveled at various bank angles? Have the distance or time vary based on the severity of the bank angle and you can keep the rocket traveling straight up within a predetermined cylinder... which may be tilted or skewed, but would provide a safety margin that could be mapped in 3D space but allow the rocket to move around within that space as needed.
Well done. Need a steerable chute to bring it back to the launch pad.
This is gonna be a banger.
Your production quality is getting better as fast as the guidance system! Keep it up! Love your videos! 🚀
The sound recordings from the rocket are great!
talking about precision - is there the measurement error assessment and/or objective control?
It's crazy how many people don't understand ITAR
Wait.... Are you saying the US State department & Pentagon In all actuality DO NOT sit at their desks watching BPS Space & Lafayette Systems UA-cam 🚀🚀 videos!? 😁😁😜😜😜
people are joking
And many advanced technologies will not let you know. Just like Snowden's PRISM , it is basically impossible for you to know if it is not exposed. This is just nothing Intellectual freedom is not actually free, and is not freedom of speech.
Nice work. The level of control is impressive. Those onboard camera sounds are sweet.
Bro's building the next-gen Iron Dome or Patriot Battery at home.
Keep it up, excellent work, mate!
idk why but the fact that he uses names like Data Link and INS is amazing, probably because i'm using to hearing it when i'm playing DCS but i love it
Why did you choose to go for carbon fibre PC for that connection point on the avionics assembly? Adding fibre to a filament makes it stiffer but makes it slightly weaker and more brittle/lower impact resistance. For that piece you want a material with high strength and impact strength, but stiffness isn’t important from what I can see. Something like a TPU or polypropylene would likely be better here with polypropylene likely being the better choice although it is difficult to print.
At time 7:27 accidental is misspelled…just minor thing. Love the full video, description, etc. What you have accomplished is what we dreamed of 60+ yrs ago…back when red one transistor radios with a white wired earpiece. to hear Sputnik beeps as it passed overhead.
Excellent work. Very professional
17:23 please correct me if I'm wrong but isn't adding more perimeters to a part more effective strength-wise than upping the infill percentage?
From my understanding that is correct
Are you using Euler angles (rotated) or are you using quaternions to determine the current orientation of the rocket?
Holy crap I did not know you could casually just put step by step instructions on building a homemade guided missile on youtube and not get disappeared
Dynamic waypoints when
😭😭😭
naw tracking midair is crazy
What if your way point is moving like real life scenarios? Love this video and also the safety part.
Absolutely insane, well done. How much do all the components for the rocket cost?
Outstanding presentation of the system. Looking forward to Hatchet.
Haven’t even watched the vid yet and I’m less than 30 seconds in and i already subscribed, this is the kind of content I love to find on UA-cam
wow that’s gotta be the coolest thing i’ve ever seen
I was at Muncie,on 4th flight,I have your video on my ch. Cool stuff back in the day we couldn't have Guidance due to 911. I'd love to print your rocket for my fun.
Heya, do you plan on making any merch at any point?
Why not have an IAS sensor to tune the control loop in function of the airspeed and also detect optimal parachute deployment?
It looks like your rocket deploys before apogee, but i might be wrong
Looks like flight 5 might have actually worked quite well too if the pitch limit hadn't kicked in. I wonder if that limit could be relaxed above some minimum altitude? After all, the higher pitch only becomes necessary if the rocket is already quite high.
Yeah I think flight 5 would have gotten pretty close! I may relax the pitch limit a bit. I think the limiting factor is being able to pitch up to vertical after reaching the waypoint. If it reaches the waypoint going horizontal, the rocket may not have enough energy to do that pitch-up. This is a hugely limiting factor and really restricts the types of maneuver I can do with this small rocket. I’ll need to go higher and faster to really get into the fancy maneuver profiles.
put a photovoltaic sensor on the rocket body and point a laser to a know position in space so that its pierce point is on the waypoint trajectory. reference the simulated reference(from flight controller) to the triggered results detected from the laser. collect enough resulting differences at different positions to calculate the range of certainty. awesome build.
You have a Cool Channel and Project.
I love those *_DIGI XBee radio Modems,_* I used a lot of the Digi modems, I started using them back when they were still called *_Maxstream_* long before Digi bought them. I used the frequency hopping spread spectrum, the direct sequence spread spectrum and the XBee. But I like the 900 MHz direct sequence the best. I used them the on my UAV's for the control links and data down links. On one trip to Australia while we were conducting test for the Australian Outback Rescue, we tracked one of our UAV’s over *_20 kilometers_* using a pair of one Watt 900 MHz Digi direct sequence spread spectrum modems. We were the first team to fly into and come back from the Outback Rescue search area.
I used the direct sequence spread spectrum modems on my redundant spread spectrum R.C. link. I could configure a redundant system for *_900 MHz or 2.4 GHz or a combination of both 900 and 2.4._* I had the same issue the *_ITAR police,_* I was doing this in the late 1990's to mid 2000's I had all kinds of visitors from all kinds of 3 letter agencies. This was long before most people knew what a UAV or a drone was and I would get reported to these agencies on a regular basis. At first it was scary but after a while it became a pain in the ASS.
Instead of printing parts at 100% infill, print them with 99 walls (obviously that many walls won't actually print) - walls provide strength along the axis you need for the application of chute line anchor.
I remember when Mark Rober tried making something and someone in defense told him it was illegal to do so 😂
We shoudl seriously turn this into a hobby just like how drones and RC Planes turned to a hobby.
This would be so much fun.
Did you drop the /s?
Bro doesn't know amateur rocketry is a hobby. Check this guy out! 😂
For representative statistics, it would be great to randomize the waypoints👍(maybe within a certain radius)
this guy has either a million recruiters in his inbox or already an amazing job
People in the 90s: its rocket science. People in 2024: here is a youtube video about rocked guidance, open to the public, for free. Made by an amateur.
This is motivating me to try and make a guided missile for my large-scale RC planes
I think that might be a crime
Skymaster F-14’s chasing each other with functioning sparrows would be the future of xtreme sports!
@@Gl1tchy_B01_09 Yeah, I'm not gonna actually do that. Just in theory.
Might sound dumb but could you install a edf fan in the rocket inplace of the rocket motor then you could have near unlimited test flights . Would probly need a contra rotating edf to cancel out the torque of the motors
Congrats!!!
1. You could put 2 or 3 waypoints on each flight to gather more data.
2. How precise is your measuring system of actual path and how it works?
Pretty sure he cant talk about no2
Sweet!
Probably getting real close to crossing some lines here lol if not already!
Well done!
Great work so far! I can't wait to see the next few flights!
Are you using PID's? The wobble in the roll suggests overshooting caused by large gains. It would be useful to tune these systems a bit more, but you may even need to apply another factor on all the modifiers depending on what air speed you have which is changing the control strength.
Homemade sidewinders, I will be following
You should setup an algorithm verification pipeline which tests the control sw in sim everytime you make a change.
It is a bit more work in the beginning but will pay thicc dividends in the end.
Cheers!
Random idea but maybe for the silo have it jettisoned out in a manner similar to what destroyers have. There's the initial launch to get it out of the tube then the rockets ignition kicks in to prevent damage to the tube. That may resolve the problem of wrecking it.
Damn I love your videos so much
Pls keep it up
btw, the AIM-9s have a control system, which are increaseing their control athority step by step after launch. Seems lke a good idea for Diamond-X as well
This reminds me of the bleed air on the fins of some soviet missiles (igla? Or was strela)
@@nikolaideianov5092what do you mean ?
Awesome video as allways! 🥳
Fantastic vid. Really cool tech and amazing footage. The last video to were cool but this one was next level. Can’t wait for the next.
Well if a cruise missile is not next, then how about a parawing chute and self steering back to base? Awesome job!!!!
What kind of autopilot structure do you use (3 loops, 2 loops etc....)?
Thanks!
Congratulations 🎉
Welcome to the 3 letter agencies list 😂
You can do the same with a gyro. in fact that's how Autopilot works in some aircraft. Also you could make this a radar guided system using tracking software connected to the control system.
Why don't model rocket makers use counter rotating blades that fold down, along the rocket body while under thrust but fold out (and spin) when the rocket is coming back down instead of using parachutes to control the rocket's descent?
We have been making "video" guided rockets and drones for the past 9 years using both visual and IR cameras and combined the two recently. No gps or rf jammers to worry about. 😂😂 I'm currently working on a multiple spectrum system now that combines many different spectrums to make them even more fail safe. 😊
measure any bedsheets with that ruler lately?
Thought about making a crossbow that launches model rockets
This is most interesting shit I've seen in a while now. What's the ground control software visible at 8:18. Did you develop it yourself?
You should add 3d sbs video of the xyz flightpath animation. Crossing your eyes would really show its true flightpath in all dimensions
I'll have to install a few of these on my property so when the neighbors piss me off... lol
Child: Can we have an Iron Dome?
Mom: We have an iron dome at home.
I love the external design of this rocket. Do you have plans available to recreate it as a "dumb rocket"?
Needs popout wings and a ramjet engine!
Can you please do a beginner video on how to get into rockets and electronics? Could you provide resources or like a Google doc or something.
in the future try and build a cool launch system. maybe with kinetic energy (flywheel) or an electromagnetic rail or something.
Just my opinion, but I feel like a thin metal washer fixed to either side of the parachute attachment point on the wishbone with an adhesive would go a long way in limiting the risk of the 3D printed material failing when it experiences that big shock load.
Amazing video! I'm quite interested in the fin's shape, how did you come to the four small wings? What's their purpose?
Stuff like this illustrates the changing nature of modern warfare.
