Finished Helmet The helmet is almost finished. It contains a 5.8Ghz RX, a 1.3Ghz RX, 4 way video splitter, Xbee, EPI-OSD board, Wireless head tracker, and LIPO alarm. I have one triple pole switch to swap RXs and video feeds and another triple pole switch to power the EPI and Xbee and...

Circular Polarized Antennas Circular polarized antennas are the way to go for flying vehicles. When properly designed, they have the ability to reject multipath interference. That translates to better video and usually better range. Watch this video: http://www.vimeo.com/8826952 IBCrazy on...

The ACC was only included on the MK3Mag for use in other robotic applications and for a future head tracker application.

I haven't seen that before. Thanks Ken.

That's not me. There are photos of Simon's quad on RCG. One is below. BTW, Welcome to the site.

Funny you mention waterproof. I'm mocking up something right now. I's basically an upside down quad. The electronics are going in the tub on the bottom and the battery will sit on top. Here's a video for you: http://vimeo.com/groups/Mikrokopter/videos/10051940

Yes, I got the baro and magnetometer. The baro support is crude at the moment. I recall there being an accuracy of a couple meters but someone recently posted code that brought that down to 20cm. There is support for the magnetometer in the code. I have no idea how well it works. From what I...

It's on a Jakub frame that costs $70 I think. You could build this on an old yard stick and plastic tub from the dollar store. So including a 3000mAh battery it was a little more than $200. Motors and ESCs were about $10 each. The new Quadrino board I bought is from here...

It levels well. I can snap the sticks and the quad will hit about a 45 degree angle and bounce back immediately. I do need to use a lot of trim to maintain a level hover. It's a problem with my setup that I haven't figured out yet. I ordered a new board that has all the sensors built-in so I'm...

Yes, you can balance the motor with weight, index the prop differently on the motor, etc.

Darn it. Now I need one also. Droider: http://en.wikipedia.org/wiki/DGPS DGPS allows for a little better accuracy by using an error signal from a ground station.

Can it be upgraded to a hexa or octo frame?

How about propeller and motor vibration analysis with the ground station software. I wonder if Frederick already has that for openpilot: http://www.mikrokopter.de/ucwiki/en/VibrationTest

Autotune PID loops!

Am I correct in remembering that servo support in multiwii isn't quite finished yet? Have you seen this? http://www.declspec.com/quadrino-datasheet.pdf He may be coming out with a very small board with the same sensors. That may be a good option if/when the multiwii firmware can properly...

I think you are referring to what they call gimbal lock?? http://en.wikipedia.org/wiki/Gimbal_lock I don't think that is what is going on but I'm not an expert and I don't currently have a camera mount installed to test. If you simply roll the MK to the limit of the camera mount does the...

I may not be understanding the issue but there is a setting to adjust camera nick and roll. Is it called compensation? Can't remember. What I do is to temporarily put the settings to level the mount on potis. Then I level the mount and put the values into MKTool. Then I will put the...

I wouldn't suggest flashing firmware wireless.

I bought 3D capable goggles for my bird just for 3D cameras. This is the one I've had my eye on for FPV: http://www.nghobbies.com/cart/index.php?main_page=index&cPath=1_8_112 It's expensive and It doesn't look like it would survive a crash very well though. BTW, Youtube has 3D capabilities...

There's no more information in that thread. You can click the thread link at the top right though.
