Wireless is supposed to be cool. We all love Wi-Fi, Bluetooth, Zigbee, radio and television, mobile phones and various gadgets and instruments freed from any cable, as long as we don't worry about the electromagnetic pollution caused. Are they harmful for living organisms or not, and if so, to what extent?

TAPIR is assembled from 7 small PCBs

Does this worry you? If you want to learn how dirty the ether really is, then the E-smog detector is what you need. Also known as Elektor Tapir* this tiny electronic device with an antenna comes as a complete kit including two types of electromagnetic detectors and earphones. Sturdy and easy to build thanks to a comprehensive Construction Guide  the three-dimensional assembly will sniff electro smog of almost any frequency.
