The Raspberry Pi rocket camera project will need a rocket. For this purpose, I have started the construction of Hyperion II. Hyperion II will be a fiberglass-reinforced water rocket capable of operating at pressures up to 12bar with a peak thrust of 15kg.

At the moment, I have spliced the two pressure chambers, 3D printed the coupling that allows me to connect them as well as 9.5mm nozzles. Here is a short video showing the construction progress.
