Build a Redneck RF Detector!
(files.catbox.moe)https://files.catbox.moe/jeqyfb.jpgThis is a very simple RF detector, which you can build yourself for around $10, with many potential uses. It could be used to see if the CIA is putting words into your brain!!11! (

To construct this, you will need:
- A 0-1mA panel meter; you may need to search for "ammeter" or "milliammeter". Found one on Amazon under the "Baomain" brand (yeah, you can guess where it's coming from) for $9.
- A germanium diode. The 1N34A signal diode is pretty common. Be careful, they're fragile; don't bend the leads near the body.
- A 0.1uF ceramic capacitor.
- About 28" of stiff copper wire; a scrap of #12 solid electrical wire will do.
You'll also need a soldering iron or a crimp tool and a crimp connector.
Form the wire into an antenna, you want a deep "U" about 3" wide and about 12" tall. Attach one end to the negative terminal on the ammeter. Attach the capacitor and diode between the other end of the antenna and the positive terminal of the ammeter. MAKE SURE THE END OF THE DIODE WITH THE STRIPE CONNECTS TO THE TERMINAL. Aaand that's it.
