PulseStar: An Open Source Argon-Ion Plasma Propulsion Kit
Project type
DIY Technology
Date
5/12/2026
Location
Fort Collins
Pulsar is a desktop argon plasma thruster you build yourself. Feed it a small argon cartridge, turn the dial, and 15,000 volts ionize the gas into a glowing violet plume. The same physics NASA uses to push spacecraft through deep space, sitting on your workbench. A ring of neodymium magnets shapes the discharge. A brass needle valve gates the gas. An honest, 3D-printed kit you assemble in 45 minutes with a single hex key. No vacuum chamber required, no PhD required, no soldering required. Just real plasma, real high voltage, and the most beautiful physics in propulsion, finally in your hands.
