To get a password, touch the banana.

The administrator of a Danish company, who received the task of providing guests with temporary Wi-Fi passwords, did not stoop to such trivialities as printing a list of passwords on paper or providing a secretary with reception access to passwords. Instead, he built an automatic system for issuing temporary passwords using the Raspberry PI, the Makey GO board and the banana.

To obtain a password, a visitor needs to turn to a special stand. On it is fixed Raspberry PI with a screen connected to it. The program running on “Malinka” issues temporary Wi-Fi passwords valid for 8 hours. But the issue of passwords does not occur at the touch of a button - instead of a button on the stand, a banana is fortified.

The banana is wired to the device. Makey Makey GO is a small fee, the creators of which in the summer of 2015 successfully received funding on the Kickstarter crowdfunding platform. The fee, the distribution of which to buyers began only last month, works on a capacitive principle and, when touched, emulates a key press, sending the appropriate commands via USB.

In the commercial of the board, its creators just connect various conductive objects, from donuts and apples to bananas, to this board, and those magically turn into controllers. Touching an item changes the capacity of the system and the board is triggered by sending a push code via USB to a connected computer.



Everyone is happy with the result - visitors smile, passwords are issued automatically, no one takes care of the secretary in the waiting room, and the administrator does not need to print periodically. True, someone needs to periodically replace the banana with a fresh one.
