Battery Discharge Analyzer
This project builds a simple automatic battery discharge analyzer. It can be used to measure the discharge characteristics of the batteries. The output data can be expressed into a graph with a spreadsheet by sending data to PC via RS232.[more]

AVR Datalogger Zero
AVR Datalogger Zero is an AVR development board that is designed to experience data loggers. This board is designed by Chris Kern. It is mainly intended to help develop experience with technology useful for building data loggers, specifically sd card storage and ethernet connectivity. The board is designed for low power operation. Most onboard systems are powered by a 3.3v switching regulator.[more]

Data Acquisition System using ATmega8
This project use a PC for GUI display and AVR Based data converter board. The circuit is built with the ATmega8. The GUI programming with Visual Basic to receive data from ATMega8 vai RS232. The ATMega8 chip has the onchip 10-bit resolution A/D Converter. Temperature sensor are connected to the 6 channels ADC input. You can connect up to 8 sensors with the ATmega8 TQFP package. [more]

AVR910 – AVR programmer
AVR910 is a very useful AVR programmer based on AVR910 application note by ATMEL. It can program almost complete range of AVR chips. The programmer uses ISP capability of AVR chips. It is one of the fastest programmers for AVR.[more]

AVR-based power usage logger
This device monitors household power usage and logs it to an SD card. A simple analog front-end amplifies the signals from voltage and current detectors and an ATmega168 microcontroller computes the power consumption using the formula P=V*I. The voltage and current are each sampled at 9615 Hz so the integration should be fairly accurate even for highly non-sinusoidal loads such as computers or fluorescent bulbs[more]
