CyberSpar is real-time interactive martial arts training system is built based on AVR ATmega16. Incorporating high-quality digitized audio and speech feedback, it simulates a bout with an opponent while providing audio motivational cues and other helpful feedback. It offers three different skill level settings, with bouts ranging from three to six rounds, and is designed to be very user-friendly and economical. The sensor(s) and speaker are separate from the electronics themselves and connected with regular 2 conductor wire via jacks.Themi Kotsiras explained that the impact sensor used in this project ...

The project implements a canon RC1 remote control that allows the user to trigger almost all Canon SLR cameras from a distance. This is a great utility project with minimal extra components. It consist of AVR Butterfly (AVR ATmega169), an IR LED and NPN transistor. The Remote is shown here powered by an external 9 volt battery to increase the range if the remote but it can also be powered by the butterfly battery itself. This digital camera control firmware is written in C and compiled using AVR-GCC."Most modern cameras ...

According to Wikipedia, Electroplating is a plating process that uses electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material, such as a metal. Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g., abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.)In this project, Robert Papp built an electroplating controller based on Atmel AVR Butterfly Kit. It control two main physical parameter for an electroplating bath, the temperature ...

This versatile data logger is built around the AVR Butterfly. It is a cost effective solution that monitors light, temperature, battery voltage and external sensors. The external sensors can be digital signals, analogue voltages or a frequency. There is provision for up to four external analogue sensors in addition to those shipped on the butterfly for temp, light and battery voltage. Although the digital sensor interface is currently designed to use Phillips I2C it could easily be expanded to include a Dallas 1-wire bus as well. Simple wake-up circuitry was ...
