DIY electronics workshop
Introduction to the physics of electromagnetic field spectrum and audio spectrum with drawings. What are EMF waves? How do they travel through space? Which EMF waves are harmless, which are dangerous, and why? We detect EMF with a coil. A coil is an electrical conductor in the shape of a spiral. We use electromagnetic coils in electrical engineering in applications where electric currents interact with magnetic fields in devices such as radios, electric motors, transformers, and sensor coils. An electric current is passed through the wire to generate a magnetic field.
In the workshop, we will first uncover how a coil is connected to an electric device. Then we will build a test coil with conducting copper wire wrapped around a pencil. We will connect it to a breadboard and listen to a crackle of the electromagnetic field in electrical devices around us such as a soldering iron, laptop computer or mobile phone. Next, we will use an industrial-grade coil and solder it to a stereo audio jack (3.5 mm) that participants will connect to a loudspeaker. We will listen to the EMF emissions in their immediate surroundings.
No prior knowledge is needed to attend the workshop. The workshop is free of charge. Girls welcome!
The workshop is a simplified version of a three-day workshop for field recording and sound mixing Tentacles for electromagnetic field.
