Ok, i build one zapper for curiosity_research_purposes. We did it really good in a box etc, i measure it, and the output is aboyt 5.6 volt 30-33 KHz. I will ask some friends to see if we can make the test i describe.
Off of the zapper topic, just for information - i don't know is there in USA, but in Europe there is a medicine called Rimantadine. It is really strong against flu (type A), you are fine in just one day and 6 pills :) The price of Rimantadine is exactly 11 times less than Tamiflu. The advantage of Tamiflu is that it is active against all types of influenza virus (types A and B).
