  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 ...
  2. The complete WLAN solution for AVR and other CPUs Software The software needed to drive the SPI2CF consists of two main parts: The low level drivers needed to access the PRISM compact flash slot via SPI and a (hardware independant) TCP/IP stack on ...
  3. The complete WLAN solution for AVR and other CPUs The SPI2CF chip used in the SPI2CF demo system is based upon a cheap CPLD. The necessary WebPack ISE development system is available as a free download from Xilinx. It can therefore be used for ...
  4. The complete WLAN solution for AVR and other CPUs The page is about equipping an Atmel AVR microcontroller based system with a PRISM WLAN interface. This document is intended for people that already have experiences with the AVR microcontrollers ...
  5. Overview The “Simple Wireless Security System” monitors the open/closed state of two (garage) doors. Sensors detect the state of the doors, and a Zigbee wireless transceiver sends the state information to a PC. The PC runs a GUI ...
  6. Introduction How many times you needed some remote control to handle some electric device ? many times. There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more. The basic small-range remote controls are 2, Infrared ...
  7. Here is my home-built, cloth iron soldered, range extender for CC1101 (included onboard) RF transceiver chip from Texas Instruments. You could say that it is a CC1101+ CC2591 , but for 868/920MHz band. I used MAX2233 RF amplifier from Maxim-IC. It ...
  8. John Samin The original diode in the Microwave detector has been hard to find. I have found a supplier for the diodes... Purchased here: Site Main Page : ...
  9. Jerry Wasinger I. Introduction In the Midwest, the main topics of conversation may include the local football team or how the crops are doing. Inevitably though, the conversation always leads to the weather. Most of us take the weather for granted ...
  10. Features so far Displays menu via serial port if attached to PC Can run unattended or interactively for debugging Fetches GPS positions and sends them via SMS every two minutes If the circuit is powered on, the following sequence will be executed: ...
