I saw this on the Web and found it interesting:
Do you think it was all programed into the GPS, or did it have some direct communication to correct its course in flight?

Massive day at Maker Faire yesterday, with Jordi manning the booth in the Maker Shed and me bouncing around with kids between that and the GeekDad booth (shown above), which is my other hat here. We gave a UAV talk on the main stage at 6:00 and then did a photo shoot outside for next month's Make Magazine.

I bought a BlimpDuino today at the maker faire. I hope to have it made by the time I go to the borg meeting.

What can it do:
the atmega 128 can control all the servos and the engine speed. It can communicate with my Windows PC via the xbee so I can send it commands (like inc/dec engine speed, tail rotor servo, etc). It know's it's pitch, roll and heading using the sparkfun 6DOF + the compass (combined using kalman filters).
What can't it do?
well, first off it can't fly (yet). it can't even control it's horizontal direction using… Continue

Your Blimpduino kit comes with most of what you need to compete the blimp, and all the hard-to-find and unique parts. Here's what else you'll need:
- A soldering iron and solder
- A FTDI cable (DIY Drones cable recommended) to program the board.
- Helium (Available in the balloon kits available for $18 at Target, or a…

Here's how to load the Arduino code on Blimduino:
First, you need to download and install the latest Arduino IDE
Then, download the latest Blimpduino code from the code repository
Unzip the file. You should have a directory that looks like this:… Continue

The UAV Devboard is back in stock at SparkFun, with a new design.
The reason for the design change is that Analog Devices no longer makes the gyro that we were using on the previous board, so we have switched the design to the LISY300AL. Paul Bizard and I have thoroughly tested the new board on fixed-wing aircraft, the LISY300ALs work just great with DCM.
We have modified all of our existing firmware to be able to run on either… Continue

"The world's first 6-axis MEMS-based motion processing solution delivering the smallest, most robust inertial measurement unit (IMU) for CE applications. This solution includes two 4x5x1.2 mm packages for the gyroscopes and one 3x3x0.9 mm package for the accelerometer, providing a small 7x7mm equivalent footprint with 10,000 g-shock… Continue

I'm sorry to report that FMA is no longer carrying Z sensors. They ran out of existing stock and because their basic Co-Pilot doesn't require them, they won't be making any more. They will continue to make XY sensors, which the Co-Pilot does use, and those should be back in stock in a few days.
We're currently exploring alternative sources for the Z sensors, but in the meantime, I suggest you buy them from Dean Goedde for… Continue

Hello again! I'm not so good making intros, so imagine you just read a long and well redacted introduction of why uBlox (the best GPS ever) is so difficult to find and interface with (Specially the SparkFun version). So let's go to the point. ;-)
If you are beginner please don't try to make this.
Fallow this pictures in order to make… Continue

It would seem I’m not the only one using ArduPilot1 code so I fiddled with the code and took some extracts from
Ardupilot 2.1 and used it to save the home alt in the EEPROM.
When the autopilot resets it self during flight or is reset by the user (quick 5 times toggle of AP switch) the home position (WP 0) would reset and for that given position during the flight the alt. will be “0”.
If you descend the alt would read something silly like 65000 subsequently with AP armed… Continue

-I want my UAV to be able to go from point A to point B, take a picture, go back to point A and then land safely.
-My UAV should be built using the cheapest commercial available products and the total cost should not exceed 1000$.
-I'm giving myself no more than a year to complete this project.
List of my skills:

Integrated picoc as a runtime thread in VicaCopter. The current version locks up, it doesn't do floating point, it crashes your entire autopilot when it encounters an internal error, but after working around all the problems, managed to get some nifty flights out of it.
It's like turtle graphics with a very very expensive turtle. U can build up incredibly complex flights out of reusable maneuvers. U can repeat maneuvers. U can nest maneuvers in maneuvers.
Ironically, picoc… Continue

I got the Radio Interface running today and am talking thru the XBee radio to the Ardupilot ground station. I'm not sending all the data yet, but most of it. That's my house down there!
That just leaves the SD card as the last bit of hardware to validate. I'll probably wait a bit on that and focus on getting the magnetometer integrated with the attitude estimator. Then I think… Continue

Got the Altitude sensor working (BMP085). This graph shows the responds from holding the autopilot near the roof then lowering it to the floor, then back again. All in all about 8 ft. A little noisy, but not too bad. I haven't attempted any filtering of the data yet.
This graph shows the accelerometer data as I hand held it and did several rotations about the roll and pitch… Continue

The more we get into the RC world, the more we're shocked by how overpriced and underpowered a lot of RC equipment is. Most of the specialty electronics, from ESCs to servo amplifiers, are just cheap PIC chips with a few support components. The parts cost a few dollars, but the completed boards often sell for as much as ten times… Continue

This version has many additions, including the support for three different GPS protocols (SIRF, NMEA and UBX) and can be added as many are possible.
Has the well integration of the pressure sensor and battery level conversion with an offset for the ADC voltage to increase accuracy in the conversions.
Has been debugged using the ArduPilot… Continue
