Need to take some secret spy photos? Make shows off a simple way to build a spy camera inside a coffee cup using an Arduino.
This one’s about as silly as it gets, but it works well. It’s built so when you lift the cup up like you’re taking a sip, it snaps a picture. If you’re caught, you can rotate the cup to hide the camera. The build uses an Arduino, a cheap camera module, and an accelerometer to trigger the picture. You can find the full build instructions over on Make.
