Atmega Alarmclock & Thermohumidity meter

First, rise and shine, let me introduce you to my project. I’ve crafted an Alarm clock with extended functionality, including a thermometer and a humidity meter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register […]

DIY: Retro Style Analog Volt Meter using Servo Motor

Digital equipments have rapidly replaced Analog equipments in the long run. Well that is because the former has lot of advantages over the latter. But do you miss those retro style analog measuring instruments? Those pointy indicators and graduated scales? Well I do and so have decided to build one with the “modern” parts. This

Light Tracker Demonstration

Electricity is the most required and important element of human life. We cannot imagine our day to day life without electricity. Electricity is generated using conventional (coal, diesel) and non conventional (water, wind, sunlight) energy sources. The recent and latest trend is to generate electricity from solar energy. The solar panel (made up of solar-photovoltaic

Zigbee Wireless Relay Control and Power Monitoring System Using Atmega644

Zigbee Wireless Relay Control and Power Monitoring System Using Atmega644

Introduction We designed a system for wirelessly controlling relays and monitoring current. This is used for a home load simulation. By wirelessly turning relays on and off by sending commands from a PC to a microcontroller we can change the total load (current) to our simulated home. For wireless communication, we used XBee Series 2

Self-Adaptive Hybrid Electro-Magnetic Levitation and Active Balancing System Using Atmega644

Introduction In short, our project is just an isolated floating plate. Just as our title explained, it is mainly a floating plate that is segregated from all outside vibration using electromagnetic force. This purpose of the project is to design a system that complements common passive shock absorption mechanics and enhances their performance. The main

CUAUV Voltage Sniffer Using Atmel Mega32

Introduction The Cornell University Autonomous Underwater Vehicle team (CUAUV) is an undergraduate engineering team that designs and builds a fully autonomous, robotic submarine. Over the past year, the team – of which both Manoj Lamba and Ian Wang are members – has had a stringent policy of testing the vehicle weekly at Cornell’s Teagle pool.

Galvanic skin response meter using Atmel mega32

Introduction Our project measures the user’s skin conductance for monitoring his or her mental state. Summary Medical experiments have shown that the magnitude of the electrical conductance in a person’s skin is directly correlated to their emotional state. The short term changes in electrical conductances also correlate with a person’s mental response. We implemented an
