Code Name "Sky Breaker"
Project Skybreaker is a small prototype rocket built for low altitude testing and checking how its onboard systems hold up in flight. It packs a bunch of compact sensors and cameras, plus real-time telemetry gear, so it can collect all sorts of data flight details, environmental conditions, and how the structure performs while it goes up and comes back down. The rocket runs on a budget-friendly onboard computer setup, which makes it easy to prototype and rebuild. This computer handles everything: combining sensor data, keeping flight logs, and sending down live updates on acceleration, speed, temperature, and position. Skybreaker’s also testing some experimental solid fuels, basically, looking for cheap and reliable ways to power small research rockets. All fuel batches get mixed under strict controls to study what they’re made of, how they burn, and how stable the thrust is, with safety always front and center. The current goal? Reach 2,000 meters above the launch site. That altitude gives me or the user a chance to keep improving guidance, test the rocket’s strength, and make sure telemetry stays solid. In the end, Skybreaker is about pushing the boundaries of DIY rocketry, but doing it with real engineering discipline and solid data, just like you’d expect on a professional test range.

Finishedf PCB Routing for version 1!
Finally finished the routing of the pcb, not the cleanest but it should work tried to make it as compact as possible so we should be fine about space, now its time to make some changes to the model and ask for the grant finally!

Sourced Parts for V1,bought labtools, and created hot plate!
I made sure the parts I modeled where available in common stores near me to make sure I could make more modeled rockets without also using more than 200 dollars in just prototyping. Thankfully the materials are cheap, strong, and even got a discount so we should be fine. I also bought myself a bit of lab equipment (with my own birthday money) for the fuel I am going to synthesis sooner or later. Plus im making a homemade hotplate because I cant afford the hotplate as of now, I scrapped them from my old ender 3 v2 I had, it still needs a few tweaks but it heats wicked fast. Not sure if the hotplate counts as "project time". Still going to ask because this has taken me a long time to make and its on the purpose of project skybreaker. Pretty happy with my progress, sure slow, but a good project demands a strong foundation and dedication.

Fixed Schematic and Created Ratsnest
This is the first time ive created a pcb this complicated so it took me a while to develop the ratsnest, the power and ground nets, and just fixing the schematic took me a while, since the schematic had over 200 errors. Afterwards I had to fix over 60 errors of pure logging and flags for the nets while also changing few components and choosing resistors, capcitors, inductors, voltage regulators, etc. Its still a mess but its already late, ive divided the work on 4 hours each over two days. Fingers crossed tomorrow its ready.

Schematic of V1 Complete!
Finally finished the schematic after a long (and sometimes painful) debugging session. Tracked down and fixed most of the small issues and inconsistencies along the way, and everything is finally looking solid. Now that the schematic is in a good place, it’s time to move on to the PCB design phase and start turning this into real hardware!

PCB Schematic
Getting the hang of the wiring and these new computing parts took me a lot longer than I thought it would. But once I pushed through that, I finally started routing everything. There’s still plenty left to sort out and connect, but I’m honestly confident of the progress.

Model of V1 finished!
I’ve finally got the model to a point where it should be pretty simple to 3D-print without any major issues. It took me a while to sort everything out, but I’m happy with the result. It shouldn’t be too hard to reproduce, especially since we still have a lot of fuel tests to go through.

Optimization (part 1)
One of my main goals for this project is to make it accessible and straightforward for fellow makers. To achieve that, I chose to simplify the model as much as possible, prioritizing ease of printing and rapid iteration even if that means sacrificing some maximum acceleration, distance, or velocity. This version will serve as the foundation for the design and formulas behind my rocket-fuel test platform.
Additionally, I was able to run simulations using a weaker rocket motor and still achieved nearly identical results, which was a great confirmation of the design’s stability. I’m really looking forward to seeing what this project can accomplish!

Designed V1
I’ve now begun developing the rocket’s infrastructure, focusing on determining the appropriate length and diameter. Based on simulations, the current design reaches an apogee of roughly half a kilometer using an H-class motor and achieves a top speed of about Mach 0.371. My next challenge is figuring out how to push the design to at least a 1-kilometer flight before I finalize the model. Lots of iteration ahead, but it’s exciting to see the progress so far!
