  • Flight Controller Shield for an Arduino Mega

    Posted on by Experimentaltechnik Comment

    Here is part 3 of my homemade quadcopter series. I`m making the flight controller shield with a protoshield and the 10 dof IMU the GY-80. It would be easier to buy a complete flight controller with integrated IMU, but I already have the Sainsmart Mega and the IMU and I know how they work and that they work, so I decided to use them. The advantage of making a shield is that I can try different IMUs if I want, and it`s easy to add other components like LEDs or ultrasonic senosrs to the pins of the Arduino Mega. The disadvantage is the higher weight and the time that it takes to make the shield.
    In the last part of the video I test it with the Multiwii software.

  • Featured Image Quadcopter Multiwii Settings for an Arduino Mega with IMU

    Posted on by Experimentaltechnik Comment

    The multiwii code is very large and can be quiet overwhelming at the beginning(at least for me it was), but once you know that all the important settings are made on the config.h tab it becomes more overseeable. In the following I show the settings that I have chosen so far. Here is the video in which I tested them: http://youtu.be/ad5JCKX0C40
    I can`t guarantee that the quadcopter will fly with them, because I didn`t try it yet. When I change something I will update this page.

  • Homemade Quadcopter – part 2: Making the Frame [How to]

    Posted on by Experimentaltechnik Comment

    Here is the video of how I made my quadcopter frame. It consists of 4mm laminated birch wood for the centerplates and 10mm Aluminium square pipes for the arms. With 240g it won`t win the price for the lightest frame, but it is stable, relatively simple to make and it is possible to upgrade to stronger motors in the future.

  • Homemade Quadcopter – part 1: Project Start

    Posted on by Experimentaltechnik Comment

    So I finally have all the important parts together and can build my quadrocopter. Here is the first video in which I give an overview about them and explain the basic concept. There will be more, in the next video I will show how I make the frame.

  • A2212 Motor and 10×4,5 Propeller on the Test Stand; Thrust, Current and Speed Measurement

    Posted on by Experimentaltechnik 1 Comment

    For my quadrocopter I have chosen the drive combination of A2212/13T 1000KV motors and 10×4,5 propellers. It`s time to get some data for the dimensioning. What I want to know is of course the thrust and the current at different rotational speeds. From that I can calculate how heavy the multicopter can or should be and how long I can fly with it. I screwed the motor with the propeller onto my homemade test-stand and connected it with a 3-cell Lithium Polymer battery, a 30A ESC and the Unitest 2, that I bought some years ago. Then I started with the measurement.

    You can change the values and use it for your own measurements.

  • Brushless Motor A2212/13T 1000KV review

    Posted on by Experimentaltechnik Comment

    For my quadrocopter I needed some good and cheap motors. This A2212 1000KV brushless outrunner motors from ebay seller global.mart are very cheap and in this video you can see what I got for my money. I`m also measuring the radial runout.
