Variometer is a device commonly used by pilots of various kinds of air vehicles to visualize the vertical speed. The device is of importance for the ones who want to fly without any engine like paraglider and hanglider. It help glider pilot decide whether to escape from the sink area or to start soaring in the rising area called a thermal. Because after a few up/down bumps no one is able to tell if he is still rising or already sinking without variometer. This Variometer-Altimeter project is cost-saving alternative to commercial ...

Word clock is unique digital clock that used shine word to show the time. the project is built based on PIC 16F877 and uses mains to ensure that it stays accurate. To build this project, you need to make custom PCB and make word pattern that tell the clock as etched areas. The clock use 5mm Blue LED to shines the word. "I made the stencil using another fiberglass PCB. Just etch the board using the same method you used for the controller and display PCB, and lacquer it to protect ...

The goal of the project is to design and build an AVR ATtiny26L microcontroller-based model railroad car that helps locate and diagnose problems with your layout and track in order to improve the overall running performance of your model trains. The Diagnostic Track Inspection Car operates as it is pulled around the layout with a locomotive, just like any other rolling stock in your collection. The Track Inspection Car alerts the train operator of any potential trouble spots by sounding an audible beeper and simultaneously lighting color-coded LEDs. The different ...

This project presents a unique way of tracking the performance of your stock portfolio. It uses an actual traffic signal light and lights up red, green or yellow depending on how your stocks are doing, with results updated every minute. An Atmel AVR ATmega128 microcontroller is paired with an Ethernet controller to provide connectivity to the internet. At different times, the Atmel controller acts as both web server and web client. In order to enter the stock portfolio, the Atmel controller serves up a web page where the user enters ...

The project is an autonomous robot vacuum that picks up rice named as "Sir Sucks A Lot More". The robot was built around the Atmel Mega8585 microprocessor using the WinAVR tool set. To handles telemetry and debugging of the algorithms, it uses PalmOS program. The robot is equipped with sensors to navigate around the room. The main board was designed in Eagle Cad. A beacon was built to help the robot find home. The beacon used an Atmel Tiny15 that was programmed in Atmel assembly. "I began with the idea of ...

The purpose of the project is to monitor and display the water level in a 3000 gallon septic holding tank. The system consists of two main parts: the sensor unit and the display unit. An ultrasonic sensor is used to detect the water level in the tank. It has an analog output that is proportional to the distance between the sensor and the water level. The sensor measuring distance in this case is about 8 1/2 feet when the tank is empty. An Atmel AVR ATmega8 microcontroller generates a trigger pulse ...

The purpose of portable Power Meter project is to measure and average the voltage and current from each leg of the generator, and display the information on a 16x4 LCD screen. The project use Atmel ATtiny26 as signal processing and control. While the firmware is developed using Bascom-AVR. The high voltage sensors for voltage and current are isolated from the signal processing circuit by a quad opto-isolators. The signals, supplied to the signal processing section, are analog and proportional to the voltage and currents feeding the load. The signals from the ...
