The WITNESSCAM is a self-recording surveillance camera that’s perfect for the home or office. The innovative, ATmega32-based system features a VGA CMOS color camera, a passive-infrared (PIR) movement sensor, and a 1-GB SD card. The aesthetically pleasing prototype looks like an ordinary alarm detector, but when it detects movement, it silently starts recording. You can control the camera an infrared remote. The interactive camera responds with voice prompts, and the circuit can recognize when the box is open.

I am a fan of blue colored LED’s, LCD’s, any kind of light emitting source 
, so when i stumbled on this project it got my eye immediately. The project features a Digital Clock based on Atmel Atmega8535 microcontroller. For displaying the info the circuit uses four, blue, 3mm, 7 segment LED modules. Three are used to display the hour and minutes, and the other one is used to display the status of the alarm: on or off. The clock uses a small lithium battery to keep the current time if power is lost. The alarm time and state are saved in EEPROM and restored after a power outage. If you would like to start building this Digital Clock follow the link at the bottom of this article.

Remember the article on Tv-B-Gone kit ? Yes it was a nice project that you can play with, but here come big-brother with its learning function. It means you can now teach the kit to turn off every TV imaginable. The current hardware includes an Atmega 168, a USB port, a 2MB Atmel dataflash (for storing all sorts of codes), a learning mechanism (which can detect the correct carrier frequency), four buttons (selecting transmitter and learning mode, enable USB, …) and of course four powerful infrared LEDs.
