"Proof of principle is a realization of a certain method or idea(s) to demonstrate its feasibility, or a demonstration in principle, whose purpose is to verify that some concept or theory has the potential of being used. A proof-of-concept is usually small and may or may not be complete."
This week (22-06-2013) we made Hack a Day with the PS3 long distance RC controller :).

The development of the custom PS3 controller board is finished, lets start with the transceiver!
June 19, 2013 - "Sony’s DualShock 3 controller can be seen in a number of projects here on Hackaday. There’s a reason for this: it’s easy to sniff the Bluetooth signals coming out of this controller and make any electronics project do your remote control bidding. Bluetooth has a fairly limited range, though, so what happens if you’d like to use this very comfortable and very functional controller over a mile or so? Just replace the mainboard of the controller with a new design using an Xbee radio. It’s a great project from the workbench of [Marcel] and looks to be just the solution for an awesome Xbee remote control.
The Sony DualShock 3 controller is designed around a single main board for the bulk of the electronics and analog sticks with three daughterboards used for every other button on the controller. Marcel took the main board out of his controller and stated to reverse engineer the thing, keeping the USB charging, PC communication, force feedback and LED indicators. Instead of Bluetooth as in the original circuit, [Marcel] used a 60mW XBee radio, allowing him to control just anything connected to another XBee radio with a range of up to a mile.
The new main board is a direct drop in replacement for the original DualShock 3 mainboard, and the only modification to the controller is drilling a small hole for the new antenna. It’s a great piece of kit for RC vehicles of any kind, and it’s fully programmable for whatever robotics project you might have in mind."
"Roomba SCI is a serial protocol that allows users to control a Roomba through its external serial port (Mini-DIN connector). The SCI includes commands to control all of Roomba’s actuators (motors, LEDs, and speaker) and also to request sensor data from all of Roomba’s sensors. Using the SCI, users can add functionality to the normal Roomba behavior or they can create completely new operating instructions for Roomba."

Een Nederlander heeft een wifi-module voor de Roomba ontwikkeld waarmee je de robotstofzuiger via apps of computers kan besturen.
Die Roomba-robotstofzuigers zijn handig, maar jammer is dat ze nog altijd niet standaard via mobiele apps zijn te bedienen. Nederlander Marcel is een crowdfundingactie gestart voor een wifi-module voor de Roomba-robotstofzuiger. Daarmee kan je via smartphones, tablets of computers je Roomba besturen, zelfs overal ter wereld. En je kan data van de sensoren van de stofzuiger ontvangen.
De module sluit je aan de bovenkant van de Roomba aan op de externe seriële poort met een zogeheten mini-DIN-connector. Onder meer de motoren, leds en de speaker zijn te bedienen. Ook is het mogelijk om sensorgegevens op te vragen van de stofzuiger. Eventueel zijn ook nieuwe functies te programmeren.
De wifi-module kost 69 euro. Hij moet voor 10 januari via Indiegogo 7 duizend euro hebben opgehaald. De wifi-module zou de accuduur van de Roomba nauwelijks verkleinen. Er zijn al enkele apps voor iOS en Android waarmee je de Roomba kan bedienen via draadloze verbindingen, omdat er ook al Bluetooth-modules voor het apparaat zijn gemaakt."
