Attiny EMF Detector

Attiny EMF Detector

“As is tradition, finished product image first. Inspired from masteruan’s similar build, which I will link below, I set off to build my own micro sized Electro-Magnetic Field Detector. The goals were to make this as small as possible while retaining enough stability that it would not break in someone’s pocket. The challenge to that was the antenna …

Electromagnetic Field (EMF) Detector with LM358

“In this instructable I will show you how I made an Electromagnetic Field (EMF) detector with dual operational amplifier and 2 inductors. With this device you can hear for example how your TV or phone are working. The circuit is relatively simple. For me the hardest part was drilling the enclosure.”

EMF detector 0- 999 Hz for ATtiny 85

“An EMF meter can measure AC electromagnetic fields, which are usually emitted from manmade sources such as electrical wiring, while gaussmeters or magnetometers measure DC fields, which occur naturally in Earth’s geomagnetic field and are emitted from other sources where direct current is present. First a BIG thank you to the Arduino open Source community where I learned in …
