BlimpDuino home page

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.~~

[UPDATE: The current Blimpduino kit has been discontinued. Stay tuned for a new design in 2012]

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

@Peter. Welcome! What are you working on and how would you like to collaborate? We're focused on contests initially, and the next technical tasks for us is adding a magnetometer and multiple beacon sensing.

Chris, we are very interested in your progress with blimps and would love to collaborate - keep up the great work!

@Andy. It would be pretty easy to add LEDs, but these can't be used outdoors or anywhere where there's any wind. You'd need blimps at least 4x their size (and 10-20x their price) for outdoors

Cool Concept! Did you guys think about incorporating LEDS for text on the side of the blimp...Like a floating billboard....I have no idea what it would require, I saw this post and had visions of mini blimps floating around at the next street festival passing along funny messages.

Well, sure, if you put the ground beacon on a slow-moving toy train, I suppose the blimp would follow it around. But remember that this is indoors only, and really only for altitudes of less than 2-3 meters.

Could it maintain position at a specific altitude above a moving target?

Very interesting !

Blimpduino is not full duplex. Our original one, which used the Pololu IR transceivers, was full duplex, but we didn't see any real advantage in that and wanted to save money and weight.

We'll probably do multiple sensors with a centrally coordinated Arduino beacon sequencer on the ground (one Arduino pulses multiple beacons in order) and use a trigger pulse to sync the ground and air clocks. No full duplex required.

If you include a microphone in multiple beacons - capable of hearing the sonic system,
Then you could:
1. Assign each blimp to a timeslot for pinging.
2. On each ping - take a time reading from each beacon, use the results to triangulate location.

How about a scanning IR transmitter on a servo. This is easy.
Create a narrow IR transmitter window, turn the transmitter on a servo, transmit the vector.
Either of those should work with the current blimpduino design.

Also, I'm curious, is Blimpduino fullduplex?
I only see ir receivers.
