![]() Anything under the control of a collection of home brew electronics can go haywire. If you've got the stomach for zombie movies then you'll find plenty of evidence for this on the web. In general, everything here can be done much better - plenty of room for the reader ) A word about safety- big quadcopters are very dangerous. It also means you have to know less about the fascinating arena of remote control aircraft in general and quadcopters in particular - so you can and should rectify this by taking a look at some of the great Instructables on the subject! The same thing can be done with other brands' parts - in particular anything that Deviation supports would probably be an easy enough port to Arduino. You should still order spares to build your own though! This assembly approach means you get to the stage of flying, and coding flying routines much quicker than most and is argubly cheaper as well. This, and other parts are all availble as spares, itemised below, however these little hubsan copters are fun toys in their own rate, and are probably worth the relatively cheap (~£35) asking price just to get the practice flying, and they come complete with one battery, spare propellers, charger & remote. ![]() This project leaves all the hardwork of copter flight control, radio receivers, Electronic Speed Controllers, IMU's and so on to a single part from a commercial RC copter, the Hubsan X4. It also makes use of plenty of other people's work, but most immediately the processing-serial-android library ( ) and the hubsan X4 and A7105 code from the deviation project ( ) Taster video 1: Drone controlled by tablet: Taster video 2: Onboard footage from flipping (and crashing) octo-droner: This work was inspired by the 18$ quadcopter thread on rcgroups ( ) - take a look at rcgroups for plenty more inspiration. The ability to write your own code to fly the copter make this more of a drone than many remote control projects, but you will need to develop your own code to actually decide what throttle, rudder, aileron and elevator commands to send it when - a work in progress based upon a 'Ground station' camera tracking the copter from underneath is included, but it doesn't fly it yet! As a simpler exercise for the reader, you can also look into adding forward/backward/left/right FLIP buttons to the android remote. However you go about it, this is a reasonably cheap project, the most expensive part other than my laptop and tablet is an Arduino DUE and a cheaper device could be used if desired. However if you go this route you will miss the satisfaction of combining the ancient chinese arts of bamboo lashing and cheap mass manufactured electronic toys. ![]() ![]() Here is how to make a small, indoor/outdoor quadcopter that you can fly with either: * an android phone or tablet * a legitimate remote * via your own processing ( ) sketches on a PC (or Android device) There are lots of optional steps in this project - for example, you can skip building the quadcopter, and buy one instead - you will still be to use the Arduino based radio to control it from your phone/laptop/tablet. Or how to become a drone developer without mortgaging your house.
