Step 6Read EEPROM after logged

After the soldering process and re-assemble you Keylogger, you should connect to the keyboard that you want to log and wait for the information, "legal" data, or anything you want to get from this Keylogger..
Then, unplug the Keylogger and re-plug the keyboard ;)
Now, you have to read from the eeprom, so, If you have soldered also the SDA and SCL pin to the two N/C pin of PS/2 (like it was on the circuit) you can now build a simple converter from PS/2 to ICSP connector of your EEPROM-reader (In my case, Pickit 2).
See the documentation of your programmer to see exactly how to build it.
Mine, look like this.
After read the eeprom memory, you should save it to a file for better usage. You can do this with a simple Hex Viewer.
Remember that the data collected from PIC are pure "keyboard scancodes", so you need to convert to a readable version.
You can do this by hand, basing your conversion process to this link .
Another way is to use my homemade program, made for make this process easier.
I've attached it, but BE AWARE, IT'S A ALPHA VERSION, it's FULL of bug and REALLY not optimized.
By the way, it make his work quite well..
It's an Italian Version 'cause I'm Italian ;)

Step 7Conclusion

Here we are. 
I don't know how many will have the bad idea of make this Keylogger, but, if you really want an homemade (and almost free) solution to log a keyboard, this is what you're searching!
