Da chris anderson di wired un bel post su un blimp (mini dirigibile) automatico: un drone

BlimpDuino is a very low cost open source autonomous blimp. It consists of an Arduino-based blimp controller board with on-board infrared and ultrasonic sensors and an interface for an optional RC mode, a simple gondola with two vectoring (tilting) differential thrusters, and ground-based infrared beacon.

It is available as a commercial kit from the Maker Shed or the DIY Drones store for $89.

• What else you'll need

• Instructions for making the kit are here.

• Instructions for loading the code are here

• Correct LED/servo/motor behavior modes are here

• Instructions for using Blimpduino are here

• The parts list is here

• The discussion forum for teams using Blimpduino in the FIRST Robotics aerial robotics demonstration is here

• If you want to build your own board from scratch, the necessary files and component lists are here

• If you want to print out a cool DIY Drones sticker like the blimp above has, here's a pdf.

The Blimpduino board is the core of the kit. Features:

* 17 grams, with ultrasonic and IR sensors.

* Controls two motors and one vectoring servo.

* Built-in RC compatibility (can read two RC channels--throttle and steering)

* Designed for a 7.4v LiPo battery; has an automatic power cut-off at low voltage to protect the battery.

Here's the board with the ultrasonic sensor removed, so you can see the Atmega168 processor underneath it:

Here is a video of BlimpDuino in flight, using a breadboard version of the controller board:

At the moment, we're using Pololu IR beacons as the ground beacon, but we'll eventually release our own, open source, versions of them, too.

Here's the board on the gondola with vectoring thrusters and the optional RC receiver:

The commercial kit consists of the following:

--BlimpDuino board, with all SMD parts already soldered on

--Other through-hole components, to be soldered by user (easy)

--A very simple laser-cut plastic platform for the board, battery, optional RC receiver, and motor components

--A servo, gears and motor shaft for the vectoring (thrust tilting) function

--Two motors and props

--One IR ground beacon

--52" mylar envelope

The following is a chronological list of posts describing the development of the project. This is mostly for those who want to follow along and learn about Arduino-based robotics.

Personally, I loved to buy stuff: I admired a consumer society. I sincerely liked to carry out a clean, crisp, commercial transaction: the kind where you simply pay some money for goods and services. I liked driving my SUV to the mall, whipping out my alligator wallet, and buying myself some hard liquor, a steak dinner, and maybe a stripper. All that awful stuff at the Pottery Barn and Banana Republic, when you never knew "Who the hell was buying that?" That guy was me.
