Mini Flight Telemetry Transmitter

admin — Thu, 29 Jul 2010 23:18:40 +0000

Morse Beacon is small transmitter that can send flight telemetry to earth from a small balloon or model plane like temperature and battery voltage, Call Sign identification and a sequence number for logging purposes. The design is made around an ATtiny13 microcontroller, a LM35 centigrade temperature sensor (or LM34 Fahrenheit), a RF module, and [...]

AVR Based Compact Email Client

admin — Wed, 28 Jul 2010 00:26:01 +0000

This ATmega32-based compact mail client project is easy-to-use and provides all the basic functionality you need to communicate via electronic mail. The project named as MiniEmail has a special stand-by mode in which it checks for new mail on a regular basis and alerts you in case new mail has arrived. Its intention is [...]

AVR Barometric Altimeter

admin — Sat, 17 Jul 2010 01:30:38 +0000

The project is a plug-in daughterboard that converts a stock AVR Butterfly demo board into a barometric altimeter with one-meter resolution named Monarch. The major enhancements from ATmega169-based system including barometric sensing of air pressure, 10–110 mbar absolute range; Barometric altimeter, 1 meter resolution, >16K meters max; Digital temperature sensing; R/C (radio control) servo pulse [...]

AVR Based Operating System

admin — Tue, 13 Jul 2010 03:41:59 +0000

kaOS project is real-time, multithreaded, preemptive operating system for the Atmel Mega32 microcontroller. It can loads and executes programs from a Secure Digital or MMC card. The system waits for a card to be inserted and a reset button to be pressed, at which point a program is loaded from the card and executed. [...]

Modular User Interface System

The IOSTRING is a modular physical user interface system which consists of a series of three basic board modules designed around the Atmel AVR AtMega88 MCU. Each module type can handle switches, pushbuttons, rotary selector switches, rotary shaft encoders, potentiometers, LED’s, LCD displays, and an alphanumeric LED display. Dual footprints are provided on each board [...]

AVR Based Rocket Telemetry Payload

admin — Wed, 07 Jul 2010 02:20:56 +0000

The purpose of the high altitude rocket telemetry payload was to design and develop a flexible flight computer to be flown onboard reusable mid and high powered model rockets. Since these designs are to be flown on relatively small rockets, size and weight were of paramount importance to the payload developed. At the same time, [...]

Low-Cost AVR Based Logic Analyzer

admin — Mon, 05 Jul 2010 03:19:46 +0000

This Logic Analyzer project allow you to monitors and captures a number of digital signals. It uses PC to display the data processing. The system consists of ATmega88-20PU AVR microcontroller as main processor and some simple components used for the interfacing with the PC, the man and the probes. The measuring instrument supports 8 input lines [...]
