Assembly Instructions
The EMF Explorer Badge is an electromagnetic frequency sensing circuit that lets you listen to the world of hidden electromagnetic frequencies all around you! So much can be discovered through listening. The way that Bluetooth hardware sounds when it’s operating. How cellphones sound when they are transmitting data. What a laptop touchpad sounds like when it detects touch. The electronics world is invisibly emitting sounds around us all the time that we are mostly unaware of. The beautifully detailed art on the completed PCB can also be worn as a badge on a lanyard, used to illuminate yourself at night, and be ready to sniff out hidden (and possibly otherworldly!) EMF signals with the use of headphones or an external speaker.
No previous electronics experience is required to appreciate and use this badge, and it’s a great way to learn more about your world by exploring the different properties of our surroundings.
Please note: This kit requires soldering and runs on two AAA batteries (not included). Ages 11 and up, with appropriate adult supervision required.
