Next Steps: UAV_Zwo

Since UAV_Eins is MIA since a couple of weeks, my projekt slowed down a little bit.

I also burned my arduino board, and had to replace it. "5V" really means output, NOT input... ;)

The new arduino arrived a couple of days later, together with the em-406a GPS module.. :)

The first GPS-code a copied from the arduino HP worked perfektly.

I also ordered a arduino prot shield to… Continue

Winners of the 2008 Outback Rescue competition

(above: crashes and near crashes at the competition)

From the press reports:

TOOWOOMBA man Simeon O'Neill and his best mate used their patched-up 30-year-old model plane to beat teams of university aerospace engineers at the UAV Challenge in Kingaroy. Mr O'Neill and his high school buddy Aaron Donaldson, from Geelong, won the main event, the Search and Rescue open category,… Continue

Poll: how important is a 5HZ GPS to you?

I mentioned in a previous post that we plan to make ArduPilot compatible with both 1Hz and 5Hz GPS modules. The problem is that the 1Hz EM406 that we're currently using is a 5v device and all the 5Hz devices we're looking at are 3.3v. So to be compatible with both, we'll have to put a power regulator on the board (right now it just uses the RC receiver as its power supply), and that will delay us another month for board fabrication and testing.

So my question is: how important is 5Hz… Continue

SpaceX countdown on now!

This has nothing to do with UAVs, but it's cool all the same. SpaceX, the Elon Musk company that aims to be the first private effort to make it to orbit, is scheduled to launch their fourth attempt this afternoon, sometime after 4:00 PST. All details and live webcast as soon as they start the countdown… Continue

Declocking the new ArduPilot boards

Nothing every works exactly the way you'd hoped. We're testing the new ArduPilot boards and it's looks like we'll need to tweak a few more things. One stems from our decision to run the CPU at its top speed, 20Mhz. That's the best way to get maximum performance (it gives us 20 MIPS), but it introduces some incompatibility with the standard Arduino bootloader and libraries, which for legacy reasons run at 16Mhz or… Continue

Final production ArduPilot boards are in

So cool: the final production ArduPilot boards are in--they're really tiny! We just have to burn the bootloader and upload the ArduPilot code to check all the components. Assuming everything works, we'll just give our production partner the green light and three weeks later I can send you to the page with the "buy now"… Continue

Totally new antifail system code (uses interrupts and timers, OMG! )

Well better read the source code and enjoy, please try to customize the code to your own system.

You need an attiny85 and is programmed with AVR studio (don't forget to desactivate the CLOCK DIVIDED BY 8) it uses the internal crystal, you need also a mux like 74ls157, or either you can use the output pin to read it with you microcontroller in… Continue

UK FPV Legality

Just been reading the latest BMFA News (British Model Flying Association); they've got a small article about European UAS Seminar 2008 they presented at - essentially they're saying that the UAS guys needs to get their act together! Apparently they're unhappy that the UAS community don't have an umberella organisations, and don't appear to be taking safety seriously...

The other article that caught my eye was entitled "First Person R/C". It summarises their safety concerns, and lists… Continue

Sweet Tango

DraganFly, released a Bi-Plane UAV, TANGO , very very nice looking.

the specs, here, are very promising.

Just one doubt ... will the target of $1000 be respected??

I'm back!

Woot offs are great! I am hoping to buy a recorder like the one i posted for sale the other day :) we go...

We're no longer loading down that poor little predator. Infact, it's role has be relegated to a training machine versus the final project. The main board has changed to something else, lower powered, but, still fun. No programming will be changed, and the basic idea of a network based remote controlled UAV will still be in that plane. The full project isn't… Continue

Google Android autopilot?

Now that Google's released the open-source Android OS for cellphones, who's up for creating an Android autopilot?

You can start with our Windows Mobile autopilot code.

nMine UAV Controller, more hardware options than anybody could need!!!

Hi, I would like to present my project, i know there are a lot of uav projects but i think it is a amazing balance of price, performance and simplicity! It is based on OLIMEX E2468 board and Sparkfun sensors.


4 Layer board with ground plane for high noise immunity I/O Connectors:

- 8 x Servos - Standard pitch 2.54mm

- 4 x speed input (for sensors, motor RPM, or PPM capture)

- 2 x CAN BUS with transceivers - Header 2.54mm

- 10 x Analog… Continue

Stay tuned...

No i'm not done, nor have i given up. but a few things have changed, and almost all for the better :). in the middle, and almost done with upgrading almost every computing system in my network. New components have arrived and need to be tested. Also have been learning linux, which i have decided is going to be the main OS of the my project. I have until Februray to finish off this project and get my frist autonomous flight logged. If it is not done by then, that will be very… Continue

Ten days till goes live

Dean Goedde's highly-anticipated Attopilot, in Pro, Basic and RTL form (estimated costs: $800, $400, $100), will have a proper home in ten days, when his site goes live. [UPDATE: Dean doesn't have an exact date for availability, but as he notes in the comment below, he expects to start taking order in 4-6 weeks, with units shipping around… Continue
