The author made the project for a friend who wanted to include it into an amplifier as an extra function. The project turned out really well and it works flawless. It’s based on the ATmega8 and it uses a 4 digit 7 segments common anodes led display to show the time. The code is pretty simple, written in C, but it lacks comments as the author did not felt the need to add them.

The LM35 of National Semiconductors that is used in this project is a precision centigrade temperature sensor, which has an analog output voltage. It has a range of -55ºC to +150ºC and a accuracy of ±0.5ºC . The output voltage is 10mV/ºC . The output voltage is converted by the AD convertor of the ATMega8. The temperature is displayed on an LCD module. In this example the thermometer has a range of 0ºC to 40ºC and a resolution of 0.5ºC. If you want to have a readout in Fahrenheit you can use the LM34.

Some would say that an electronic dice would take the fun away from the game, but I’m not sure that’s always true. Anyway as the friends from PyroElectro say “we’ll make it anyway”. It’s based on the ATmega8 which controlls 7 LE’s that show you the number. All the schematics and source code is available for download.
Every gadget gets hacked sooner or later, it’s just the way things go. Some people get bored and can’t help themselves not hacking something to make them different, unique. In this case, you’ll be learning how to install a Wii modchip.
The WiiKey modchip doesn’t actually go on the Wii’s motherboard, but the DVD drive’s motherboard, effectively sitting between the DVD subsystem and the Wii’s DVD interface, and it tells the Wii that any disc inserted into the drive is an authentic disc of that Wii’s region. The Wii never suspects that the DVD drive is lying, and that’s why the modchip allows you to play backup up games, homebrew, and so forth.

ATMEGA8 DevBRD is an open source development board for the Atmel ATmega8 build especially for Linux users. The board is well suited for beginners who just want to start learning the avr programming but also for advanced users who want to use it as an MCU board.
