Arduino Rocket Thrust Measuring System!

- In this video i will build an Arduino powered thrust measuring syetem that will not only be able to measure max thrust but create, using excel, a thrust over time graph! This is great since it allows to see how my motors perform during its entire burn.

I want to thank you very much, im just too lazy to learn c++, and needed desperatly a test stand. I made one by you and it works perfectly fine.❤
This literally made my day thank you! That is the goal with my channel, to teach people cool skills. I wish I could post more but this summer I should post another video or 2. If you have questions let me know!
just started doing this myself! can’t wait for the next video man 😁
Very well done project, I can't wait to see the "Engineers Cut" soon!
That custom PCB board is pretty sweet too.
That's what I was looking for! Complete project with sources
I am glad you liked it, i will be posting a more in-depth video soon but if you have any questions let me know!
add a relay, pushbutton, time delay and use electric igniter and you're all set!
I am so impressed by this project and very happy to see you share it! As an older guy who has been into model rockets, electronics, Arduino, and so on this is very inspiring. I have not yet tried 3d printing nor custom PCB design but perhaps one day I will. Frankly the skill set you laid out in just 10 minutes is very impressive not to mention the work that I DO know goes into making a RUclips video. Wishing you the very best and hope to see your channel grow! Perhaps you or someone affiliated could make this project into a kit for sale. Building kits is more my speed rather than duplicating all of the steps presented. As a side note I used to work as a Mechanical Technician in the Test Lab of Rocket Research setting up and firing rocket engines in large vacuum chambers where we collected pressures, temps and thrust of both prototypes and production small engines. Cheers!
Thank you very much! I look forward to putting out more videos very soon. Having kits would be a pretty cool idea! Maybe one day when I have a bit more time I could make kits out of some of my projects. And that is awesome you got to work with real rocket engines, they are incredible machines!
Love the color of that box
Just the video I was going to look for.
Very well presented informative and enjoyable to watch. I’m Looking forward to watching the engineer cut and will probably now use a printed PCB myself for my test stand. I wouldn’t mind knowing what influenced you to opt for a vertical test rig instead of a horizontal?
I am not sure if vertical is better than horizontal, however if I went with a horizontal test stand I’d have to find a way to hold the stand down since the motor would be able to push the test stand. Since it’s vertical all the thrust goes straight down so i don’t have to make the stand very heavy
Now that you have tested code and hardware, increase your sampling rate from 10 Hz to 50 Hz or 80 Hz which is the maximum for the HX711. Your Arduino Nano can easily record at 500Hz using a 16 GB SD card. The newer and larger memory cards have internal data buffers. It may require a minor change in your code, but higher sampling speeds opens new areas of understanding.
I have found that anything past a few GBs in SD card size lead to the card not working with the arduino. Also to change the refresh rate of the HX711 I believe I have to solder something on the board and I don’t want to risk messing that up. But a higher refresh rate would be better that is true! Thanks for you reply
@@theeverydayengineer1701 My HX711 board has a jumper to switch from 10 SPS to 80 SPS. I know some pcb's do not have a jump and require cutting and soldering traces.
I use the SdFat library in my Arduino projects. That allows me to use 32 GB SD cards. Update your Library Manager and add these two lines of code at the beginning: #include "SdFat.h" and
SdFat SD; . I recently updated to SdFat 2.2.2, but I have not completed testing it on my non-Arduino projects.
Great video 👍.
great video
How many kg was the load sensor, I am in a rocket club and trying to determine which to get, the rocket will be heavier and bigger than the one in the video. It will be made out of aluminum and were hoping the weight to be 8-10kg.
Hey, I used a 10kg load cell from Amazon. I do think they sell load cells with higher ratings. So maybe check Amazon and see how big of a load cell Amazon sells? If that doesn’t work then you might have to search for a supplier somehow
@theeverydayengineer1701 thanks! I have another question though lol. Would there be complications using the sensor horizontally? Were thinking about doing this way to avoid having to 0 out due to the motor weight.
@@Bobby11567 you could definitely have your stand horizontally, the main thing to worry about is that your test stand has to be much more secured, since your thrust is horizontal your test stand could fly away if your not carful. But I think horizontal would work just fine
Is the "Engineers Cut" available yet?
Unfortunately I won’t be posting anything until summer. I have college classes and work so I just don’t have the time sadly. But if you have a question I could answer it in the comments!
What is the nozzle diameter
0.3 inches is the nozzle diameter
