A Pi-based camera that will record what you’ve just seen at the touch of a button has been designed by Johan Link and put it on a cap.

It consists of a Raspberry Pi 3B, combined with a 1080p USB webcam and a 5000 mAh power bank. These are attached to a baseball cap in order to shoot footage from the point of view of the wearer.

The camera records continuously, saving the last 7 seconds of recorded video when the button is pressed so capturing things just after they’ve happened.
