Well done! Unit looks great. Please keep us informed of how well it works.
Did you do a test of coating using the corona discharge preparation versus coating without the preparation?
You have set me thinking of alternative High Voltage sources that are readily available.
-Neon sign transformer with a rectifier on the output. (5-30kV).
-A car ignition coil with a driver circuit
-A corona module from an older scrapped photocopier. (The one I have is 5kV)
