Canon EF-S Protocol and Electronic Follow Focus Two years ago, I spoke with a film maker who told me about the problem of manual focusing with the video enabled Canon DSLRs. As the focusing sensor works only when the camera’s mirror is down, when in video mode, with the mirror up, the camera switches into manual focusing mode, via the lens focusing ring. Several solutions exist on the market, but they mainly use mechanical links to deport the focus ring to more accessible place on the camera rig. Some electronic solutions exist, but they use the Camera’s USB input and the focusing speed is quite low. I decided to dig into the communication protocol between the camera body and the lens. Canon EFS lenses are connected to the body via a 7 pin connector. Marta So Mourning of the Father of the Nation, King Sihanouk Norodom, in front of the Royal Palace of Phnom Penh, where his body has been exposed to the public for three months. On Monday 15 October, “Father of the Nation”, king Norodom Sihanouk of Cambodia died in China, aged 89. Born in 1922 he lived through the most turbulent moments of Cambodia’ s history, witnessing independence from France, Lol Non’s coup, life in exile, Khmer Rouge regime, Vietnamese occupation, UN protectorate, power struggle between Cambodia’s political factions and, finally, peace under (not official but still) one party rule. By the end of his life he gave up throne to his son, and spent much of his time China, where he has always been warmly welcomed.

Log In Quad position hold with mouse sensor (reproduced) You might remember this blog post by Marko Klein Berkenbusch on using a hacked mouse sensor for position control of a quad. With some help from Marko himself, I've mostly repeated his results on a branch of ArduCopterNG and thought I should share how I did it as it's slightly different. Please note that this is not official ArduCopterNG code, there's no support or anything for it.

It was built by reverse-engineering the encrypted protocol. Emokit has been deprecated in favour of emokit. Open-source Matlab toolboxes such as EEGLAB, Fieldtrip, and the Neurophysiological Biomarker Toolbox (NBT) can be used to process data from the electroencephalography.
Cloud Engine - Embedded Tools Embedding a 3D Gallery Embedding Sculpteo's 3D gallery on your site allows users to visualize and choose from a multitude of models on the same page before making their choice of purchase. Embedding a 3D Gallery or a shop from Sculpteo Sculpteo's gallery of 3D models easily integrates to your site using an iFrame (an HTML element which can be copy-pasted into any site). PX4FLOW Smart Camera - PX4 Autopilot Project PX4Flow is an optical flow smart camera (it provides the image for setup purposes, but it not designed to capture images like a webcam). It has a native resolution of 752×480 pixels and calculates optical flow on a 4x binned and cropped area at 400 Hz, giving it a very high light sensitivity. Unlike many mouse sensors, it also works indoors and in low outdoor light conditions without the need for an illumination LED.
Hemming a curved edge by machine When I was a young sewist, I made a ton of circle skirts which, oddly enough, I learned to make from a Usenet newsgroup (I am old and a nerd). I wore them over brightly colored crinolines like a 90s goth version of Cyndi Lauper. The one thing that always stuck in my craw about circle skirts was the hemming. Curved edges can be quite a pain to hem, because the raw edge that you fold under is bigger than the seamline.
