This electronic circuit detects changes in local electro-magnetic fields and converts them to human-audible sounds.
Electro-magnetic fields are all around us, but are usually invisible and silent. This detector uses two inductors to give a stereo audio output of the noise created by electro-magnetic fields.
This is useful for investigating electronic circuits, checking power supplies and investigating the unseen world around us.
This kit includes a high-quality PCB, all the components, an enclosure and a pair of in-ear earphones.
This is an easy kit to build and should take in the region of 1 hour to construct.
Note: The sensors need to be close to the device being measured (touching the outsheath of a cable for example). The output totally depends upon the EMF field so the stronger the field, the louder the sounds.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
Matt Little from The Curious Electric Company is an electrical and electronic engineer mainly working on renewable energy projects.
He is also a founding member of Nottingham Hackspace in the UK and is interested in helping people make stuff. Every so often there is the need for a device which has not been fulfilled elsewhere. Hence the projects here are a random mixture of things, including LEDs, displays, micro-controller development boards and renewable energy products.
