David Simpson’s Bug-in-a-Book Kit for Covert Listening
David Simpson was contacted by MAKE to create a spying device for MAKE Volume 16, so he came up with the Bug-In-A-Book project, a hacked together wireless listening device embedded in a hollowed out book. As Simpson explains at Maker Faire Bay Area 2011, a project using scavenged technology has flowered into a product with a kit that DIY folks can build and experience for themselves.
