bfauska: Thanks for the kind words my man! I just believe that we all help each other on here whenever we can, and I like giving back a little of what I have gained from the community.
puffyeye: If you use a "regular" computer, you will need a way to interface the buttons, switches, or sensors to your PC.
The easiest way is to order a keyboard encoder, which takes switch inputs, converts them to certain keys being pressed on the keyboard, and sends them to the pc. Examples would be keywiz, ipac, etc.
But with a project like this, that wont have over 4 or 5 inputs to deal with (unless im missing something here), so a paid for keyboard encoder might be a bit of a overkill.
On a keyboard hack, you remove the "brain" of the keyboard (usually a small circuit board with copper contacts.)
You use the keyboard hack by shorting two of the copper contacts to simulate a certain key being pressed. (The keys connect in a pattern called a matrix, there is no common like there would be on a keywiz, etc.)
Now there are some major drawbacks to doing this. First, it is rather difficult to construct (but Ive already done that), and if a bunch of keys are pressed at once, the computer might receive false key presses. (This is called ghosting.).
You can solve most ghosting issues by using diodes to block certain parts of the matrix.
Also you have to run two wires to each switch, since there is no common you cant daisy chain the switches, but I don't see this being a problem on this project.
After I studied up on keyboard hacking I decided to use a keywiz, since I had 2 joysticks and 16 buttons, and I figured that would be a ghosting nightmare.
Of course I had already done what I do best, jumped the gun and hacked a keyboard.
Don't know why I held on to this hack for so many years, I am a bit of a hoarder I guess.
Anyway, if you want it, and you can tell me what inputs (keyboard keys) you want to use, I will connect wires for those inputs.
If you don't know but still want it, that's fine. You can hook it to a pc, open notepad, and start shorting the terminals until you find the keys you want. (I had the terminals mapped out on a piece of paper, but its gone.)
Only drawback is that this was hacked from a PS2 keyboard, so the PC has to have the PS2 keyboard connector (round). If not it may be possible to use a USB to PS2 adapter.
