DDR Plans (part II)

Well, like I said before, I will be using a keyboard to attach buttons to. I have gutted it, and I have pictures :).

If anyone wants to do this themselves, and are unable to take the case apart, make sure you unscrewed everything. There were some tricky screws under the rubber "legs" of this keyboard.

Inside, quite compact (very good :) ) I found a microcontroller that claimed itself to be a Chicony MC17003.

The buttons aren't capacitance based, but are actually simple switches. Thus, adding buttons should be as simple as randomly pluging in switch leads between the two black headers. Of course, one would have to avoid buttons like ctrl, shift, enter, winkey... stuff like that. This will be guess work.

Now to test the buttons. Here's my testing "rig" :) :

By the highly scientific method of "poke-and-check," I have concluded that the best "rows" to use will be somewhere around the 7th slot on the bigger of the headers.
If you use linux (I do), you have an excellent program at your disposal called showkeys. Run it with the -a command to see which keys your poking corresponds with. Here is my output.


That's all I'm going to do today. Check back soon for more DDR pad goodness ;).
Out.
