README
README.mdManifesto
I believe that anybody who wants to should be able to build rockets in their garage.
I'm not talking about shitty cardboard rockets that you can buy on Amazon. I mean real intelligent rocket systems capable of actually getting to space (or at least high into the atmosphere).
The goal of this repository is to help make that possible. I want to build a community where people come to share their designs, get inspired and learn from each other.
I'm new to the rocketry scene, but I intend to learn quickly. I will try to document my entire journey right here. All of my designs, code and schematics will live here, open-source, for anybody to use or improve upon.
Enjoy.
Repo Structure
All designs related to my rocket projects will live here. Everything from CAD files, to PCB designs to code for flight computers (once I get there).
The structure will likely evolve over time, but for now I'm thinking something like this:
- Root directory (You are here)
- Rockets folder
- A list of rocket projects I've worked on
- Each entry will be a folder containing files for that particular project
- Satellites folder
- A intend to design and develop satellites at some point too
- Rockets folder
Contribution
I am just one person, and I'd love for this to be a community effort.
If you'd like to share your designs here please reach out to me at braeden@brhall.dev or just make a PR :)

Questions
How big is the Lulu v1 PCB?
It measures 36 × 64 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lulu v1 use?
93 parts, built around the DPS368XTSA1, W25Q16JVSSIQ, 2450AT18D0100E and LSM6DSV80X. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lulu v1 KiCad files?
From the broskicodes/elrocket repository on GitHub, at the commit this page was made from: the board is PCBs/ion/v1/design_files/lulu_v1.kicad_pcb and its schematic PCBs/ion/v0/kicad_design_files/lulu_v0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lulu v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask broskicodes before reusing the design.
