Circuit Lake

This project will detail the build process, and parts to build an Underwater ROV (Remotely operated underwater vehicle) with video camera. The project plan is to make it a flexible platform that will allow user to add new features like leak detector, temp/pressure sensors, depth, air lift balloons, torpedo, sonar, grabbing arm, artificial horizon, compass, [...]

Xarias is embedded car computer system, based on ATMega32 MCU and programmed using C language and compiled with gcc compiler. The project is designed to obtain different car information and display it in human-readable form. It can calculate momentary and average speed, calculate momentary and average fuel consumption, show engine RPM, calculate journey time and [...]

This low-cost stripped down mobile payment system features Radio Frequency Identification (RFID) for identification, 4-digit security pin authentication and Ethernet Data Transfer. The ATmega32-based project prototype is intended for a low-cost secure payment system that has the potential to change lives in rural areas of developing countries.

This project shows you how to construct a PCB drill machine driven by a master-controller board and three stepper motor driver boards. These four single sided PC boards each contain an Atmega16/32 microcontroller. Communication between the boards is performed using the RS485 protocol with all communication initiated by the master-controller. The PCB drill machine firmware [...]
