I love my crazy hard hat, but if you really want to audit some wifi it’s not the most inconspicuous option. Beacuse of that, I built the Fruit Box with some parts I had around my workshop.

The Fruit Box runs a Raspberry Pi and a Wifi Pineapple with an embedded battery and additional 5ghz adapter. You can utlize basic controls on the Pi to start the wardriving app or SSH in to the box for full control.
