I don't know why you think this project is boring. I think this is fascinating!

Would you be able to write a little bit as to how it works? Some questions below on what you could include:

What makes it an E-field probe (as opposed to "H-field"). I imagine you still pick up some H-field?

Also, what frequency range does it work at? How is the frequency response /directivity?

You are correct that it does not sense only electrical, but also to a certain degree, magnetical field. It is just a very high impedance unity amplifier and that's it. Since its input has a high impedance in range of 10s of Megohms, a very tiny capacitive coupling like placing it nearby to a source of noise while not even touching it provides enough coupling that you can measure it using an oscilloscope, spectrum analyzer or so.

Hey man really cool project. How much is the amplification? Standard 12 or 20 dB?

The amplifier is just a buffer, therefore its voltage amplification should be near 0 dB. Its purpose is to have high-Z input  (several Megaohms in parallel with several picoFarads) and 50Ohm output.

I was under the impression that you needed some application for e filed probing.
Examples - https://www.tekbox.com/product/TBPS01_TBWA2_Manual.pdf or the Rohde & Schwarz HZ-15 (Probe set) + HZ-16 (amp). 

To be fair, i've never had to measure e or h field. i'm currently looking to get a set of probes + spectrum analyzer for the office, so i'm really curios about the subject.
