Wireless Keylogger-Do It
Yourself! Part 1 - Introduction Familiar with the concept
of hardware keylogging? A hardware keylogger is a perfect solution for monitoring user activity, at very low risk
of disclosure. A hardware keylogger is a purely electronic device, so no access to the. . .

Yourself! Part 2 - Power-up Once you have a
transmitter-receiver pair of devices assembled, it's time for the first test. We recommend to use a single
computer for testing both devices. First, power down the computer and connect the transmitter unit between the
PS/2. . .

Wireless Radio
Data Link - This is a description of a very simple unit
designed and constructed for use as a wireless data connection between two nearby computers. The error rate is
excellent over short runs, and the transmission speed means that a useful PPP. . .
Xsboard Parallel Port Interface - that is programmed into the CPLD. . . [Application Note by D. Vanden Bout]
XSPIII Cable Interface - that configures the CPLD so it emulates a Xilinx Parallel Cable III interface. This allows
you to use the WebPACK programming tools through the simple XESS downloading cable. . . . [Application Note by

µC's Serial Port - 10/10/96 EDN Design Idea Interfacing
an X-Y keypad to a microcontroller usually uses a parallel port of 8 bits or more. But with the circuit shown in
Figure 1, a more efficient interface using a microcontroller's serial port reduces the number of connect. . .

Z80 Computer - The successor to the Great Z80 Computer project. The new Z80 computer is much simplified in
comparison to the original, but in many cases borrows ideas and circuits from it. When it is working I will be
able to extend it as time permits. . . [Written by Hans Summers]
Z80 Core #1-Z80 CPU & Memory Pdf - In simple words you can
say that the AFC will lock the receiver to any valid RF signal. To the right you can see a basic block diagram of
an receiver. The RF signal enters a mixer (yellow) and mixes with the VCO (green) . . . [maxit91 AT hotmail.com]
Z80 core #2-RS-232 drivers for the SIO - The purpose of this
project is to explain how a cordless phone works. You are allowed to build this project, but the law forbids you
to use it in the purpose to listen to other peoples phone conversations. . . . [maxit91 AT hotmail.com]
Z80 Core #3-Z80 CTC & SIO - This is the third receiver I will
explain to you. This receiver is built on a minimum number of components and with superior performance of all my
previous receivers. . . . [maxit91 AT hotmail.com]
Zeiss OPMI-1 LED Conversion - I was lucky enough to get an old Zeiss OPMI-1 surginal microscope, with very high quality
optics. Surgical microscopes differ from conventional ones in that they leave plenty of room between the subject
and the microscope to work with hands and tools, which makes them ideal to work in electronics. . . . [Roberto

Zero-Power A/D Converter Uses Printer Port - 07/06/95 EDN Design Idea You can use a desktop or laptop PC to monitor physical variables
such as temperature or pressure. A convenient way to do this is to connect an A/D converter through the
ubiquitous Centronics printer port[. . . [by Dhananjay Gadre, IUCAA Instrumentation Lab, Pune, India]
