sry i'm newbie here.
i have a lot of old keyboard in my home.
keyboard PCB has microcontroller inside right?
there is any idea to change old keyboard PCB to some kind of microcontroller device?
just my idea:
-computer software can turn off/on numlock led
-change the led to some relay circuit
-connect that relay to other device
-so i can turn on/off TV or other stuff from my computer (old keyboard use PS/2 port, my keyboard use USB port)
is my idea can do that?
any comment?
(sry if my english bad)
