If you’re looking for a fun project to teach a kid the wonders of electronics tinkering it’s tough to beat a book that lets them spy on their siblings.
Designed by David Simpson for MAKE Volume 16, the Bug-In-A-Book project takes off-the-shelf parts and, with a little DIY elbow crease and crafting, turns them into a clever hollow book laden with an FM frequency bug. You can easily adapt his tutorial to any object large enough to hold the electronics–eavesdropping Millennium Falcon, perhaps?
Watch the video above to see the inside of the Bug-In-A-Book and then hit up the link below to grab the full write up from the digital edition of MAKE Volume 16.
