Signal Conditioner for Sensorless BLDC Operations
This is a back EMF signal conditioning circuit that can be used to develop high-voltage sensorless motor drivers. When a sensorless algorithm is used to control the BLDC motor speed, the Back EMF (BEMF) signals are used. Based on zero crossing of BEMF signals, motor commutation is...

ATtiny 85 EMF detector
arduinomaster @ instructables.com has build an EMF detector based on ATtiny85 mcu able to detect signals from 0-999Hz. He writes: An EMF meter can measure AC electromagnetic fields, which are usually emitted from manmade sources such as electrical wiring, while gaussmeters or...

Attiny85 EMF detector
by masteruan @ instructables.com: This is a simple tutorial to create an EMF detector. You can use Arduino for this job, but is better use a microcontroller called Attiny85. It is possible program it throe the Arduino interface. Attiny85 EMF detector -...

Attiny45 EMF Sensor
by Khaleel123 @ instructables.com: This sensor is very sensitive and can pick up electrical signals from anything that uses power. It displays the amount of interference it picks up by sequentially lighting 4 led's one after the other. I have tested it all around the house and its...
