Don't show that to Alex.

But seriously, that is pretty impressive. Magnetic field sensor and bluetooth built in all under a $100 price tag is awesome. Who needs quad manufacturers when the gaming companies keep developing inexpensive gear to build on? As long as we have great programmers like Alex, we can enjoy some pretty impressive features.

I already saw your mad videos
Who has not yet seen it ??
I really think MultiWii with WMP only config would allow you to fly like this. It would cost only $30 or $40 to try.
My flying skill is not good enough to show you, maybe one day

ok i will try it so i need a wii motion plus adapter and an arduino pro mini, right? something else?

and how i understood, i can switch between autoleveling and 'headlock' mode?

If you have motors, propellers, esc's, accu, frame and interface for programming Arduino, you are ready - go for it
you will can switch.

What that would have an idea??
strange...
For the moment, I've no hint or explanations

Are you using Turnigy Plush ESCs ?
If yes, configure them in HIGH mode.

So this does not feels like the right way to correct the LCD-stick-issue...
I admit it's not the best logic
But it is the case:
- to start the motors: full yaw right only
- to enter in conf mode: full pitch up + full yaw right. If you do full pitch up before, the motors won't start

Yes, very tempting. Not enough documented for the moment (refresh rate, way to interface with a arduino). But the ratio sensors/price is incredible !
The equivalent at sparkfun costs 2 or 3 times more: 9DOF IMU

For Wii components, it depends:
- If you want to have a head lock attitude only, you need only a Wii Motion Plus
- If you want the auto level + head lock functionality, you need to have a Wii Motion Plus + a Nunchuk. But the stability of this solution is not as good as the WMP only conf.

For a first test: take only a Wii Motion Plus
And I don't really think you and especially you need the autolevel function

Arduino: several options:
- arduino pro mini 5V/16MHz + FTDI adapter 5V (smallest solution)
- or arduino nano
- or a classic duemilanove 328 (cheaper but bigger)

I wait for my 3 blade props to find out if I have to change code to suit MODE2 radio

Until then I have 4 similar props... and lots of rotation...but it works to do handheld tests with minimum gas applied

thanks

i bought the arduino pro mini and a ftdi adapter

and the wm+ i will buy at a lokal store. thats it.

during my shoppinground i saw a gps for arduino, did u ever think to integrate this?

I thought about it, but it would be a lot of development. And a GPS needs also a baro + a magneto to work efficiently on a multi.
Arducopter with WMP sensors could be a good alternative.

The gyro roll axis is opposite than correct , why?

Hi all!
I've mounted the multiwii software on tricopter (it was running with baronpilot software since yesterday). All mounted (the sensors) like in the instructions of Multiwii. Is all ok, except the direction of roll of the gyro that is inverted. In practice when the right side go down, in a right roll, the gyro roll value become a negative number, not a positive number like the (correct) value of the accel roll; Is it possible to correct this error without to necessarily phisically rotate the WMP?

Thanks

(I'm not greedy........I just like my toys!)

Nice to have a read back through your thread Alex, I've been away for a bit working on the Arducopter. I missed lots of development here, but took the time last night to update myself, code and GUI. Still an awesomely stable platform, working really well. (still left the NK off...... until it's sorted)

I do however have the same problem as Sid3ways, where I have motor shut downs with slight impacts. I'm using HKSS ESC so does the same apply to them regarding the high/medium/low settings? [EDIT- Just checked, seems I cant change those settings on HKSS.......bummer....]

Thanks mate,

George

Is there any reason why my gyros has stopped working? they are connected and they have the nunchuk connected to them which is working.

I hope I haven't damaged anything.

Arducopter isn't good for me. The board is too heavy for my VTOl airplane applications.

Just wait for them to do the hard part and port it to two ProMinis or a teensy++ That would be nice and light. Keep up the good work. I need to jump back into your project after I finish some other stuff. Your also seam to be really good at making the code base nice and small! I wouldn't mind purchasing some ProMini or Teensy++ shields from you also.

@Alex
to do very fast flips/rolls like the ones that Warthok does with the kk board, maybe some changes in control code are needed.

I can do easly stall turns, high banking turns, large rolls and flips with a much heavyer and bigger quad that warthox mini quad (bilding a smaller and faster one too ), but for aerobatic purposes maybe is better to cancel interaction to other axe motors when performing full stick manouvers.

On the configurator, simulating fast back flip on the X axis, at full stick I see that the front motor is full throttle, back motor is min and the 2 Y axe motors are lower than previous point.

Perhaps this behavior helps on fast flight but limits aeobatics speed... am i right?
