Hello there,
This is a little bug-zapper that works with a computer FAN and a CCFL inverter.
The insects will get sucked-in and then get zapped by a 2kV arc :D
It's powered by a 9V battery and is easy to use. The compact design also makes it mobile.

Signing UpStep 1: Requirements
• a sheet of cardboard (or PVC pipe, better)
• cutter knife
• hot glue
• computer FAN
• CCFL inverter (paper scanner or screen back-light)
• a 9V battery
• a 9V battery holder (clip)
• some wires
• a push-button
• some bare wire
• electrical tape
• high voltage diode (3kV+) or three times 1N4006 or 1N4007
• high voltage capacitor (500v +) (somewhere between 60nF and 10nF, NOT HIGHER!)
(using a bigger capacitor won't harm the circuit, but it would become lethal).

The inverter circuit doesn't really draw a lot of current, so the battery doesn't die that fast at all, but I never emptied a battery with this so I don't know how long they last :/
For saying a random number, I think you can zap 100 bugs with it :P
Good project.
It is very cooooooooooooo,e+560,oooooooooooooooooool!!!!!!!
I wouldn't try electrolytic capacitors because they will definately blow.
Those ceramic capacitors will make snapping noises inside, which means the layers are arcing to each other trough the insulation. After that, the capacitor will just no longer work but those won't explode.
I don't really know where to get them in other countries, and even not in my own country :/
I'm a newbie when it comes to electronics and will be following your instructions almost verbatim, so I'll probably post a picture of it if I can't figure it out.
Would it be possible to give me the ebay link? Maybe I can make up some stuff from it. Something like this is perfect:
<link>
I also see a lot of these black boxes on ebay:

I don't know if these are good because I can't see what's inside, but looking at the incoming and outgoing wires, and the box size, I think it's content is exactly the same as the one from the first link :)
The inverter should be just fine.
If it arrives, and there are any problems or questions, don't hesitate to leave a comment ;)
From a compact flourescent lamp like those with E3 fittings? It might be possible but I'm not really sure.
I 'think' they also convert the input voltage to high voltage, but the disadvantage is rhat they operate on 120v (or 230v in europe)
There is no use for that here.
THANX!
You also have some nice instructables ;)
I just didn't really think about it because I thought I wouldn't make an instructable for this.
Your "Safety to the user" sounds like a little bit of experience. 8-D
You can build it your own and have as much fun as you want to :D
I hope you got a mail of it?
could you send me back the text please? I typed so much :(
anyway, here is the new video: (I deleted my previous video)
