I Tried to Break Mach 1 With a 3D Printed Gearbox

Check out PCBWay here: https://www.pcbway.com. Thank you to ‪‪@PCBWayCom‬ for sponsoring this video by manufacturing and assembling the RPM sensor PCB! Can a fully 3D-printed gearbox spin an object fast enough to approach the speed of sound? In this video, I push my over-engineered propeller launcher further than ever before. With an extreme gear ratio, custom RPM measurement, and multiple power setups — including dual-hand cranking and a drill — the objective is simple: Spin faster than seems mechanically possible… without destroying the machine. This attempt quickly turns into a battle against vibration, structural limits, and physics itself. Components fail, adapters break, discs explode — but each test gets us closer to the true performance ceiling of the launcher. RPMs over 20 000 are reached! Key questions: How fast can a human-powered gearbox really go? What RPM is needed to approach Mach speeds? What fails first — the object… or the gearbox? Watch to the end to see the highest RPM ever achieved on this build. 👇 Comment your guess: How close do you think we got to the speed of sound?
