Build an Electro-Magnetic Field Detector
Thu 1 December 2016, 19:30 – 22:00 GMT
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.
At thie workshop you will build your own electronic circuit to detect changes in local electro-magnetic fields and converts them to human-audiable sounds.
The kit is shown here and includes all components, PCB, headphones and enclosure:
I'll be on hand to teach soldering (if you've not done that before) and to get all of the kits working.
