Description
DIY Ion Thruster — Electroplating / Corona Discharge Experiment
A functional ion thruster prototype designed for high voltage corona discharge experiments. Comes in two versions:
Version 1 Spike ring
Features a circular array of built-in printed spikes on the emitter tube. The blue ring is a breakaway support to keep spike tips sharp during printing — snap it off after. Ready to use after electroplating or conductive coating.
Version 2 Smooth ring
A clean tube end designed for aluminum foil. Stretch foil across the opening and manually cut or poke your own spikes into it for a fully adjustable emitter.
Both versions can be made conductive by:
- Electroplating with copper sulfate + graphite coating
- Aluminum foil lining
- Conductive paint
You'll need:
- A high voltage source (high voltage aliexpress module (MC-901 or similar HV module)
- 3.7–6V battery
- Wire to connect electrodes
Recommended material: PETG for better dielectric properties than PLA.
