High-Power Rocketry on the Cheap
Rocketry is an expensive hobby. There are things you can do for cheap, but cutting costs too much can impact safety, or more importantly: fun. This is a guide for how you can have as much fun as possible, as safely as possible, without breaking the bank.
I'll take you through my journey running an under-funded uni rocketry society, competing on <10% of the budget of our peers, and later how I continued with the hobby on my own. We'll touch on materials, manufacturing, makerspaces and more on our trip into the clouds; cross our fingers that our ejection charges and parachutes deploy at apogee; and venture into electronics both commercial and DIY to log our altitude and pop our main chute.
Rocketry is an incredibly multifaceted hobby with so much to explore and such a great community. My hope for this talk is that I convince a few more makers to try it out by covering the breadth of the hobby in enough detail to make it approachable.
