Ionizers/Negative ion generators

[.jiMbo.]

Anyone ever heard of plans to build your own environmental ionizer?
(negative ion generator)

Any info would be appreciated.

Used to be lots of articles in Elektor, Popular Electronics and Radio
Electronics. The simplest one was a 120V to 400V step-up power
transformer followed by a voltage multiplier (about 20 stages)
using 800 V 1N4008 diodes and 0.1 uF 630V film capacitors. The emitter
was the typical sharp needle. By the way, back when I was doing this, I
found that living plants made really good emitters with no discernible
ozone production. Just put the plant pot on a good insulator and bury the
negative probe in the dirt. The water evaporation helped release the
ions. Sharp, pointy leaves worked best.

Try to look in the indexes for back issues of Electronics Now, and
for Popular Electronics. I can't recall which issue, but I believe it
was in the last three years. A library may have backissues on
microfilm. Look at the index in the December issues.

Great idea!

I *never* would have thought to try that!

What voltage were you using? Was there any positive or negative effect
to the plants themselves after extended use?

(Please e-mail if possible, my News service has become spotty as of
late.)

This works really well, I've tried it too. But... don't put the plant
somewhere where you walk past it, as it will reach out and bite you !

This of course can have a funny effect if one of you plants near a door
like to greet visitors but reaching out and grabing them.

I have read that if you get it wrong you generate a lot of ozone (bad)

What you don't want to generate is positive ions. They have been
linked to cancer, disease, psychological problems and Bill Clinton
getting reelected. You want the negative ions.
