KEYSPY Keyboard Data Logger

at 10:58 am. Filed under Cool Gadgets, Electronic Hacks

Not that I am suggesting you use this for illegal purposes… But there is something about the power of a key logger that is cool.

“The KEYSPY is a hardware keyboard logger that can record keystrokes from a PS/2 keyboard and send them back to the PC at any later time. It consists only of a PIC16C84 microcontroller, an EEPROM (24C32 up to 24C512) an analog multiplexer 4053 and a few resistors. A great advantage of the KEYSPY compared with software keyloggers is that it will also log bios passwords or show that someone tried to access the computer with a DOS boot disc. The used EEPROM (24C64) has a capacity of 8KB and can store about 8000 keystrokes.”

    OMGF. The same device (actually, a better device) can be made using just 2 components. Details here:

    Has anyone built this? I would like to try to build it but the included schematic isnt very clear.

  3. Alan Parekh Says:

    I haven’t built it, have you see this page? Looks complete at a quick glance…

    Yeah Ive seen that. The guy who runs that site is pretty helpful so hopefully Ill be able to complete this project soon. My new computer doesnt have a printer port to program the PIC controller which sucks, but Ive got others I can use for it. Does anyone know a good DIY PIC programmer to build? Ive seen a few but Im not sure if there is one that is much better than another.

    About the programmer: I only just started using PICs, and I bought the PICkit 2 from Microchip. It’s cheap, and best of all: it’s a USB programmer with no external power, which makes it really simple to use. Especially for me, I only have a laptop computer and no serial port or similar.
    It’s also pretty fast.
    I think it’s a good deal.
    Hope that helps.

    Keysnoop wants to ‘program your device’. Yes I sure want them programming that for me cause I trust everyone. Here’s my pin number…

    what is default master pasword of this device?
