Ultrasensitive wideband magnetic/electromagnetic field detector This ultra sensitive wideband “E-smog” detector adds two senses to help you track down noise that’s normally inaudible. TAPIR also makes a great project to build since the enclosure is the PCB proper. TAPIR detects electric as well as magnetic fields at high frequencies. The PCB is ingenuously designed to double as a shielded case. Each of the two antennas that can be connected to TAPIR is optimized for one type of field. Magnetic fields are detected with a ferrite-cored coil, and electric fields with a rod antenna, which is easily constructed from a length of stiff wire. Using TAPIR is dead easy. Connect the headphones, the selected antenna and switch on. Move the antenna around any suspect area and you’ll hear different types of noise and noise levels with each electrical device, depending on the type and frequency of the emitted field.
