Danish network engineer Stefan Milo used a banana to set up an 8-hour password for office guests to access Wi-Fi. The banana was wired to a Makey Makey circuit board and a cheap Raspberry Pi computer. Milo swore at one point that the banana would live in rotten eternity, tethered to the Pi, with Milo ruling over the system as Lord of the Fruit Flies. Milo says the Pi has 5,000 vouchers and could run for years on end, accommodating thousands of office guests.”]
