Laurel, Maryland, April 5, 2012: Northeast Regional Fire Management Specialist Gerald Vickers of the U.S. Fish and Wildlife Service gives a safety briefing to firefighters before a controlled burn. The burn was done at Patuxent Research Refuge's Savannah Restoration Unit to increase refuge species and habitat diversity. Specifically, the refuge hoped to increase density and diversity of rare darkling beetles and forest floor plants. Credit: Sandy Spencer/USFWS.
This is the “HobbyKing Quadcopter Control Board V2 (Atmega168PA)” [QUAD-CON16K] board. It’s bases on the KK control board. It contains three Japanese Murata piezo gyros for roll, pitch and yaw that are meant to be less sensitive to vibration than other gyros. The board has an Atmega168PA micro controller.
The board is meant to stabilise the quadcopter during flight. While there is documentation and I understand some of it I’m still struggling with this board. Adjusting the pots for roll, pitch and yaw is proving difficult but may not be the cause of my failing to fly.

Controlled Chaos
In chaos theory, control of chaos is based on the fact that any chaotic attractor contains an infinite number of unstable periodic orbits. Chaotic dynamics then consists of a motion where the system state moves in the neighborhood of one of these orbits for a while, then falls close to a different unstable periodic orbit where it remains for a limited time, and so forth. This results in a complicated and unpredictable wandering over longer periods of time.
On the second to last day of my vacation, November 2, I went to the Morton Arboretum and found they were having a "Controlled Burn". Of course I had to park and take some pictures of this—something you don't see everyday at the Arb. I was thinking of naming them "Cheech and Chong Visit The Arboretum" but decided on the more conservative naming convention.
From Moebius, the Seaview (1/128 scale) comes with a great control room. I chose to display mine outside the submarine, so it can be seen in all its glory.
I'm redoing the control box to take 6 AA batteries instead of a LiPo. I want to keep things easy, because I plan to sell the helmet.
The box will have 3 switches and 2 potentiometers. An on/off switch, a "photo mode" push-on/push-off switch, a sequence selector rotary switch, a sequence speed potentiometer, and an eye color potentiometer.

The alignment algorithm evidently knows to sacrifice those control points that it considers hopeless. This view indicates the discrepancy between the control points. Those that align well are shown as dots. Those that could not be aligned are connected with lines showing the residual distances.
This begs a question: why didn't I ditch the second frame? I tried. The result was even worse. However awkward its orientation seems to be, it helps to join the frames 1 and 3 where it matters most — at the skyline.
The distance view makes it easy to understand the orientation of the original frames. For example, it shows very clearly that point of view of the second frame (of which only a portion is visible) was a few steps away from the more-or-less shared point of view of the other frames.
This screenshot is best viewed in the original size because the dots and lines are one pixel wide. They vanish when the image is scaled down.
