Would this ionizer work? Answered
I built an ionizer in an old metal ATX power supply case.
My electricity is 230V 50Hz.
It uses 22x 2.2nF capacitors and 22x 1N4007 diodes.
The circuit is about this(with the activity indicator). I also added a small unregulated non-switching power supply for a fan that:
cools the transformer
forces air through the 5 needles.
The ionisation current calculates to 5uA/needle.
or 25uA total.
Important (or so I think) details are bold.
