: I am attempting to hack a keyboard and need some advice.
: To map out the matrix you check for continuity between the
: mylar under the keys and the terminal on the encoder board.
: Can I use a test light continuity tester, a standard
: needle ohm-meter, or do I need a digital ohm-meter?
: The LED's are mounted on the PCB and I don't plan to use
: them. Does this mean that none of the terminals on the board
: carry voltage? If not, how can I tell? Would I check for
: continuity between the led solder points and the PCB terminals,
: between the hot lead of the keyboard connector, or something completely different?
: When it is wired up, is there any way to tell if its ok, besides the smoke test (plug it in and
: see if you see smoke!)?
: Please don't tell me to buy an I-PAC. I've seen it, it's
: very impressive and I may still order one, before this is
: over, but the keyboard should work for me and is essentially free!!
: Thanks in advance,
: Marshall
