Here's a list of supplies I used:1. Large, clear light bulb
Not just any light bulb will work. It must be one that has been gas filled.
Typically, anything 60 watts or higher should work. Lower wattage bulbs typically have a vaccuum. 60 watt and higher usually have an argon nitrogen mix, which lights up nicely!
I found a 5 inch 60 watt bulb for about $2.49 at the hardware store.2. Aluminum screen, painted black
The aluminum screen will be our ground to attract the high voltage.
Instead of shelling out a bunch of money for an entire roll of aluminum screening, just look for an HVAC vent with some right on the back.
I found the one below at the hardware store for about $1.50, and the screen was already painted black!3. A cheap black plastic pot
This is going to be the holder for the globe. Since it will be used at night, it doesn't need to look pretty.
I found a black plastic pot for about $0.79, you guessed it, at the hardware store.4. A high voltage power source
This is what makes the magic happen.
I used the same monitor as the one in my Electric Fence Monitor Hack Video
With people upgrading to LCDs like crazy these days, you can easily get a 15" monitor from someone for free. You might even talk them into paying you for removing the hideous eyesore from their humble abode.WARNING:
Color monitors put out close to 30,000 volts. This voltage can harm you and quite possibly kill you, depending on the depth of the water you are standing in or how old your pacemaker batteries are. Seriously, though, be careful.
