Interview on Open Hardware Junkies and Museum Exhibit

I was recently interviewed on a new podcast called Open Source Hardware Junkies about the Jansen walker, we talked about the walker, CAD and laser cutters. It was fun and you should check it out. http://opensourcehardwarejunkies.com/2011/05/jansen-walker/ Also, I’m taking the opportunity to post these photos from the exhibit the my “Jansen Walker” and a Theo Jansen original Strandbeest last fall.      It was Jansen Walker built to my design in the an exhibition at the Verbeke Foundation. (www.verbekefoundation.com) (It's the version built by hexman, Kurt Van Houtte, Ghent) The exhibition...

A t2i / 550D Magic Lantern firmware Alpha is Now Available!

Trammel Hudson of Magic Lantern fame has started porting the custom Magic Lantern firmware to the cannon t2i / 550D. So for it seems to be an alpha release,  but I suspect that things will start moving more quickly now. In this first release the only new features appear to be audio monitoring and lens info, but that is a great start. In my opinion the poor audio quality of the t2i is in my opinion the biggest flaw the camera has right now. With manual audio control and a little skill, I think the t2i could be used to shoot feature...

Canon T2i/550D Practical Video Review

I got my hands on the Canon T2i and I ran it though it’s paces, the things I was most interested in was the video modes and low-light performance. To see the HD version downsized to 720p, you have to load the video from vimeo directly: Canon T2i, 550D Practical Video Tests. T2i Vs. 7D First a quick word about the T2i vs. the 7D. The T2i does not have that pro-feel that the higher level cameras have. The body is fairly light and it is most defiantly made of plastic, and you can tell when you hold it. For me...

Digital Video: The HD tipping point is now

Over the last few years HD video has been getting constantly cheaper, easier and better. I bought a used HD camera in 2001 (JVC HDGR1) for about $2,000 that was one of the first cameras under $10,000 that could do HD, and that it does at 720P, with some other deficiencies. For a while now cheap HD has been available, for instance last year I bought a $150 camera that could also do 720P, but the sensor was small and noisy, that and the audio quality made the footage unusable. However now the latest versions of digital...

Power required to emulate a human brain

Recently, I posted a article about how much computational power it would take to emulate the human brain, and my calculations were off by a factor of 10. I've corrected my estimates and here are the updated sections: Emulating the Human Brain The Blue Brain Project has successfully simulated 1 cordical column on the Magerit super computer (100 TeraFLOPS), and human brain has an estimated 1,000,000 columns. So with 5.2 ExaFlops, one could emulate 52,000 cordial columns. And that’s 1/20th of enough power to emulate a human brain. To emulate the entire human brain you would need approximately 100 ExaFLOPs That's a lot of...

Total Processing Power of the Internet

As a brain exercise I decided to try and estimate the total processing power of all the computers on the entire internet, and see if that is enough processing power to emulate the human brain. Since this is an estimate, I will try my best to figure it out with public data. Here was my process: Total Number of Computers No one knows exactly how many people (computers) are connected to the internet since a single IP address can be shared with any number of pc’s, but the best estimate I was able to find was here: Internet World Stats They use population statistics...

Tekzilla

So one of the random things I did at CES was watch a filming of the show Tekzilla, it’s pretty popular and use to be on “real” tv. Check it out at: http://revision3.com/tekzilla/ces2010 We’re even in a couple shots. Woo!

CES meetup!

a3o Studios, the company that I do my professional work though will be at CES in Vegas this week, and I’ll have some laser-cut trinkets to give away and a distinct lack of definite plans. I suspect most of the readers of my blog are of the technical persuasion and out of any group of people I would think that at least some of you are going to be going to CES. A chill meet-up wherever would would be cool, so leave a message, or send me an email. That is all.

US Droid + Root = Multitouch?

After having the new Motorola Droid for about a week, I've been very impressed with it’s features, usability, and experience. Previously I was using a windows mobile phone, and as far as usability goes, Android is leaps and bounds better then even the latest (6.5) version of Windows Mobile. Although, when I show my phone to an iPhone users, they generally complain about the lack of multitouch, especially in the web browser, and the on-screen keyboard. I think that feature alone will end up being a major sticking point when people talk about switching from the iPhone to the Droid. As you...

Star Trek Movie Preview

So far this site hasn’t been much for movie reviews, but I was in a preview screening of new star trek movie on Saturday and I wanted to share some non-spoiler thoughts. Before the movie, I was mostly concerned with how high of expectations I should have. With sufficiently low expectations it wouldn’t take a very “good” movie to be pleasantly surprised. On the other hand if one has high expectations it takes a better movie for it to make the grade. So with that in mind, I wasn’t sure what to expect with Star Trek movie. I’ve...
