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.\n\nI'll take you through my journey running an under-funded uni rocketry society, competing on \u003c10% 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.\n\nRocketry 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.\n\nSpecific content includes:\n- What are the engineering challenges?\n- Material Science \u0026 Composites\n- Manufacturing methods\n- Recovery\n- Electronics, commercial and DIY\n- How you can get involved in the hobby\n\nLicensed to the public
