Ionic Wind Generator + Testing Base Structure

Ionic Wind GeneratorThis project demonstrates how to generate ionic wind using only a high voltage of 10–20kV!To achieve this, I used a stun gun module (≈20kV), which can be sourced cheaply on AliExpress (see parts). I designed 10 different electrode geometries and tested various combinations to determine the most efficient setup. Based on my experiments:The best performance came from using needles as the first electrode and a ring as the second electrode.For maximum airflow, the first electrode (i.e. needles) should be positively charged and the second electrode (i.e. ring) negatively charged.If you invert the polarity, you can enjoy a beautiful blue corona discharge (best viewed in the dark). Electrode Mounting SystemI designed a modular baseplate with:A fixed mounting point for electrodes.A rail system for adjusting electrode distance.Two gantry versions are included:Toothed gantry → allows distance adjustments in 5mm steps.Smooth gantry → allows fine adjustments using a ruler.From
