Weasure is M16C/62P-based system that can weigh and measure packages for shipment. Simply place the package on it and both the weight and dimensions are instantly displayed on LCD. If user connects the device to a PC’s serial port using RS232, then the data is uploaded directly to the PC, where a shipping application [...]

The project aim is to build a quadrotor helicopter flies with 4 spinning propellers on a + shaped frame. It uses four brushless motors. Each motor will be controlled by an ESC (Electronic Speed Controller). The ESCs will be controlled by the microcontroller. This microcontroller will also take input from a RC radio receiver, so [...]

The AeroQuad project is an open-source hardware and software project to build a quadcopters or quadrocopters, remote controlled four-rotor helicopters. The hardware consists of an Arduino microcontroller (Mega-2560 or Uno) as the flight controller board and an AeroQuad shield with various sensors like accelerometer and gyroscope.
