This GM-Counter is build on 2 PCB’s. One is a standard high Voltage generating circuit, whilst the second is a Counter based on an ATMega16™ which also handles serial Communication with a host (Environmental Control).
The High Voltage generator is based on a 100 Hz Chopper, which is build around a ’555′ in combination with a standard Transformer and a Cascade to achieve Voltages from 400 to approx 900 V. (adjustable) The Regulation is just on-off (Burst) which will result in approx 1% Drift. This Circuit consumes about 20 mA at a 9 V (Battery). (more when starting up

Here’s a good tutorial from ExtremeElectronics.co.in explaining the types of stepper motors, their uses, and how to interface them with an AVR microcontroller.
It includes the xstepper code library for use with the AVR Atmega16, and demonstrates how to interface the MCU and the motor using a ULN2003A high-voltage high-current Darlington transistor array.
This tutorial is comprehensive and provides beginners with the theory and sample code to get started with a simple stepper motor project.

This Frequency Counter:
(a) works well into the RF range (I tested it to 50MHz and it was solid, unlike some of the posts here which stop working at a few hundred kHz)
(b) is extremely cheap (around $10),
(c) is portable, battery powered, and hand-held, and
(d) uses common components that are stocked at mouser.com so anyone build one! It’s based around an ATMega16 microcontroller reading frequency from a 74lv8154 dual 16-bit counter (acting as a 32 bit counter) and displays frequency on two multiplexed 3 character 7-segment displays.

A circuit made for displaying the time using 7 segment display (for decimal display) and LEDs (for binary display). I used an Atmega16 microcontroller and shift registers in the schematic. For more details contact me.

This project is a nice world clock that displays time using words. It has Polish words but can easily change to other language. The lines on the bottom are used to indicate minutes. This clock is based on ATMEGA16. [via]

If you are going to use ATmega16/32 on your next project consider using this color sticker on top. This sticker made by Miroslav Batěk will help you identify each port I/O pins, SPI, I2C, UART, JTAG, ADC and do the correct wiring on the breadboard.

The AVR robot controller (ARC 1.1) was designed as the base controller for a high school Mini-Sumo robot project. The controller is built around the powerful Atmel ATMEGA16 processor with 16kb of memory running at 8 MHz for an 8 mip processing speed (contrast this with a 20 MHz PIC which has a 3-4 mip equivalent speed or an 8mhz HC11 with about 1/2 mip equivalent speed). A 16 MHz crystal is included to allow doubling of the CPU speed. Pin compatible upgrades are available that double the memory.This board can be programmed with a variety of free or comercial tools such as GNU C compiler, BASCOM basic compiler, Atmel Assembler/simulator, CodeVision C, Imagecraft C.
