Joule Thief

[Pirate88179]

Sort of off-topic, but not really.  I have been assaulted by wood boring bees this spring.  When I stand on my patio to smoke, they bounce off my head and body.  So, I have established a "No Fly Zone" enforced by my Harbor Freight 1,500 volt fly swatter.  Score thus far.....Bill 8, bees 0.  Now, all of my friends say these bees do not sting.  but, I Googled them and it says the MALES do not sting, the females cause a heck of a wound.

I am not taking the time to determine their biology.  This is war.  My No Fly zone will be enforced!!!

PS  This bug zapper fly swatter works on 2 D batteries and makes 1,500 volts.  Yes, I have a second one that I took apart to see what was inside.

I corrected the circuit problem in my replication attemp and the efficiency is now only 36%, but this is still a bit better than a normal Joule thief. My new video is at:

Hello xee
In the video you show that efficiency is watts out divided by watts in, and I was used to think that it  should be watts out minus watts in. Will you be kind (to forgive my ignorance) to explain this a bit ?

Noooo don't tell me, sounds like you got a squadron of them.

Experiment time Bill, walk out on the patio without a smoke, do they want to play with you then  time to drag out the Jeanna Light and armed with your bug zapper fly swatter and give em what fore, try a right hand forearm then a back hand, see how that goes.

Just don't forget to duck if one gets by the defences, well you could spit at that one and gum up its wings and it'll fall to earth  .

cartoon time?

I have to say that they exhibit a lot of intelligence.  Once I took out like 4 of them....the rest of them buzzed me profusely BUT, they kept out of reach of my bug zapper swatter.  Now when I go out, I get dive bombed by these things.  They do not bother the neighbors but are after me.  That is fine...I can accept the terms of war, and war it shall be. (or bee, ha ha)  Last year, I took out over 30 of the buggers.  Possibly, they remember that.  That 1,500 volt swatter is the bomb though....it really works when you can hit one of them.  But now, they come at me in groups of 3.  It is rough out there but, I will prevail.!!!!!!

I have already tested that.  I walk out to get the mail and they are all over me.  I walk out to my car to go to work....same thing and no smoking at all during these times.  These buggers will know the wrath of my 1,500 volt swatter!!!  This is war!  It reminds me of the mice war of Australia a little while ago.  We have technology on our side.
