Make your own DIY Keylogger. Er…?
Before you start, go down this list and see if you have all the basic stuff needed to do this project on your own: * a little bit of experience in electronics * a soldering iron * a microcontroller programmer supporting the Atmel 89C20XX family The biggest problem will probably be the programmer. This will be needed only once, to program the AT89C2051 chip.
As a receiver…add a 9V battery and a hardware keylogger in a cigarette box, drop it on top of a high shelf or in a drawer and you have the perfect covert portable receiver recording the transmitted keystrokes in real-time!
I suppose that u must use a 315/433 transmitting module at the ps/2 port? What about the clock signal at the keylogger then? does it work without it?
