Playing with the ArduIMU+ V3

The ArduIMU V3 is an Inertial Measure Unit (IMU) plus an Arduino compatible processor that can run Attitude Heading Reference System (AHRS) code much like the Sparkfun 9DOF AHRS board. The hardware consists of a 3 axis accelerometer and three gyro sensors, dual power regulator (3.3v and 5v), GPS port, an Atmega328@16mhz and a lot of status LED's. The best thing about it is unlike the Sparkfun board, this one has additional analog and digital pins so that you can add additional sensors and inputs. ...more

The 3DR Power Distribution Board & Assembly

A  Power Distribution Board (PDB) is a simple circuit board who's function is to distribute the power from a battery to the four Electronic Speed Controllers (ESC's) that are used to power each of a quadcopter's motors. For my quad build Penny, I opted for a PDB made by 3DR. My rationale for this decision is that unlike other PDB's the 3DR board design includes connection heads for each of the ESC's servo headers ultimately resulting in a single plug connection that can be used to connect the ESC's to the main control board (in my case an Ardupilot Mega 2.5) and also one which can be used to power it too. ...more

Project Penny – My First Quadcopter

Ever since I first saw a quadcopter a few years ago I wanted to have a go at building one. So slowly over the last year I have been collecting all the parts, with the idea that following the completion of my PhD, I would treat myself to putting one together.This week (with some much appreciated help) I finally got around to getting my first quad build aka Project Penny finished and off the ground. ...more
