Hardware keylogger circuit with Atmel AT89C2051

The keylogger circuit built on Atmel AT89C2051 is connected between the PC connection cable of the PS 2 keyboard, the circuit is written on the AT24C512 eeprom, then the eeprom is read with the program running on the pc.

Open source DIY hardware keylogger

Keelog has decided to release an early version of the hardware keylogger family into the public domain, including full firmware and software source code, keylogger hardware electrical diagrams and documentation. This PS/2 keylogger is a 100% working and tested device assembled and used by hundreds of people around the world.

The operation of this hardware key logger is similar to KeyGrabber PS/2. We provide KeyGrab application for retrieval and analysis of recorded keystroke data. However, please note that this DIY hardware keylogger project is provided as is, with all defects and with no warranty of any kind.

    Satellite Finder Circuit PIC16F877 Digital SatLock Project

    Satellite finder SatLock name as an applied project is going, but I’m not sure Does it work? I do not know, but a good example of the contents of 128 × 64 graphic LCD with PIC16F877 (A-2ylg mt12864) and use the tuner satellite receiver (d7g2121 tuner) communication with the pic and have a lot of detail

    Following the 46-page thread on each page different shares there also some satellite receiver SMPS supply ENABLED given in MPLAB crafted with code files and sparint layout program with which you can open pcb spline with the program you can open the Satellite Finder schematic drawings available
