[Noisebridge-discuss] I want to make an Eckbox and I need help

Eckbox ( http://eckbox.sourceforge.net ) is an open source implimentation of
Van Eck phreaking. Van Eck phreaking is capturing electromagnetic emissions
from a computer monitor to eavesdrop. I want to make it clear that if I make
an Eckbox, I don't intend to use it to spy on people. I want to protect my
own computers from this attack and feel I need a Van Eck phreaking device to
check the effectiveness of things I try. The author of the Eckbox software
says it doesn't work from a long distance, so I don't think I could use it
to eavesdrop even if I wanted to.

I'm having a difficult time trying to figure out how exactly to put together
the hardware. I think the most useful sort of help I could recieve would be
if someone could tell me what I should be reading or doing to learn the
things I need to learn to understand this. I'm going to explain now exactly
what problems I'm having.

I bought an analog digital converter (I don't have it yet, it's in the
mail), but it doesn't meet the requirements described on the Eckbox site.
Specifically, the site says I should get an ADC with a high sample rate,
recommending 1 GSPS, in DIP format. I couldn't find ADCs with anywhere near
that sampling rate in DIP format. I bought an ADC with the best sampling
rate I could afford (200 MSPS, I'm cheap), and it is in TSSOP format. I
don't understand how I'm going to power the ADC, and I don't understand a
lot of the stuff in the documentation for the ADC (
http://www.national.com/ds/AD/ADC08200.pdf ). I'm also supposed to get a
breadboard, but I don't know what kind of breadboard to buy or how to use a

If someone can help me figure this out, thank you. I feel like an idiot
admitting I don't know how to use a breadboard.
