Introduction: Supersonic Rocket Model Brahmos

About: Creator of things

This project is a 3D printed interactive rocket built for educational purpose. To be honest rockets normally look pretty lame just a long metal tube. Unless someone is launching one or something is in news no one really talks about them. This dummy interactive models aims to change that.

This design is based on worlds fastest super sonic missile BrahMos designed by India and Russia. Why choose this because it looks cool. Code is very simple even a school kid can understand it. You can see intro video to take a look of what you will be building.

Step 1: Things You Will Need

Honestly it dose not require much. Whole thing runs on Node MCU and is powered by a power bank.

  • Node mcu
  • MPU 6050
  • perf board
  • 2x 9g servo motor
  • Power bank
  • 3D printed parts
  • LCD screen (optional)
  • Long USB cable ad power bank.

You can download Code and 3D printing files from here

Step 2: 3D Print Parts

You need to download the stl parts and get it 3D printed. This is version-0 in few months i will upgrade the model. Whole body is modular so that you can use the printed parts another projects if you like.

Download here

Step 3: Assembly Process

Whole boy is snap fit. No need to use glue. There is nothing much to talk about here. Everything is there in the video. I dont know why i am writing this.

Step 4: Flight Computer

This is TAARA "Terrestrial Advanced Autonomous Rocket Avionics" is an experimental rocket flight computer for model rockets. Built for teaching beginners about thrust vector control and basic control system theories.

This is where all the magic stuff happens. TAARA controls all the movements of the rocket. If you download the code from github there is a readme file include. In that i have explained how everything works.Also the code is heavily commented you can follow as yu go along

There will be a tutorial on TAARA soon. I will update it here.Flight computer is itself a very vast topic very hard to cover in a small tutorial.

3d printed files for this is also include in the download package. Please read the GitHub page also to understand how code works.

Step 5: Power and Data

You can power it directly with your PC or you can just use power bank. Whole thing runs on 5V. Please do not go above that.

Step 6: Whats Next??

At this point you are done. But there is more this was version-0 In future i am planning a significant upgrade. You will be able to plot and see data from rocket direcly on your computer wirelessly and do bunch of cool stuff.

Also there will be a small mission control program. So please leave some suggestions below.
