Even if it is to be used as a code input device it could be more convenient than using a key matrix. The guys over at Nerd Kits have put together an informative video that is based on the NerdKit however it is applicable to any microcontroller.
“The PS/2 Interface is quite easy to implement. To send a key stroke, the keyboard begins driving the clock line. On the falling edge of the clock line,…

A Washington Post reader was quoted as saying ‘If Microsoft had been put in charge of marketing sex, the human race would have ended long ago, because no one would be caught dead doing something that uncool.’” Even the Guardian’s resident die-hard Apple hater calls it “the most nauseating…
This steampunk enthusiast created his own retro-submarine themed steampunk house. While the look of steampunk is pretty neat, this house might have gone too far by recreating a shipwrecked submarine. The engineer from Canterbury, New Zealand themed his playroom with his submarine shipwrecked on a deserted island.
Built at an absurd cost of $100,000, the 12-metre by 5.5m personal den definately resembles a rusting interior of a submarine (it better for that price)….
Great overview - Making the most of open-source hardware - Electronics Weekly - Gerald Coley, Texas Instruments…
AT A GLANCE
* Open-source hardware offers an advanced start on your design.
* Open-source software complements open-source hardware.
* Open-source hardware prepares your PCB (printed-circuit-board)-fabrication and -assembly houses for high-volume production.
* You may want to share your improvements by making them open-source additions, as well.
Many designers are familiar…
