After I watch “SUPERNATURAL” TV series, I got an idea about making EMF which can detect some supernatural things like spirit, demon etc. So I looked for the project about EMF at google and I found at this link. This is the photos of mine.
And this is the schematic and layout.
You can download my schematic and layout in here.
Enjoy!
