Yet another very good idea how to secure traffic even more. I am looking forward to see this implemented in urban areas. Whit the low cost of WiFi and camera components it possible to build this into traffic lights or signs so your BMW cHUD can get these streaming life images.

This wouldn’t be my blog if I wouldn’t post a “scientific” video.
The video is from a high school physics project and demonstrates the calculations of velocity, force and acceleration of a pyrotechnic effect.

I’m off celebrating new year.
I hope to see you all in good health in the next decade.

I found this 20 minute video of a ISS fly around sight seeing tour with Astronaut Michael Barratt on youtube.
I had no idea how densely packed the whole station is with all the stuff brought up there. Space seems to be a serious issue up there.

Today I want to present a video about a different robotics concept: Softbody shape shifting though jamming. I haven’t heard about that before and personally think that it’s movement is creepy.

The video explains the concept and in the end you’ll see it move.
This is a very interesting concept if you think of bots on microscopic scale, lust like amoeba.
The less complex mechanical parts you have in a a machine, the less likely something will brake.

This video was taken from the worlds second largest fish tank.
From the youtube info, I know that the Song is “Please don’t go” from “Barcelona” and that it’s available on iTunes.

Be shure to watch this video in HD and full screen.

Even the biggest problems are microscopic if you see them in an astronomical context.

Some people know that vertigo is a problem I have to deal with. For me it’s less of a problem in planes or steel constructions – but old brick made buildings above ten levels scare the hell out of me.

I spent this january in Dubai and was quite happy, that our room was only at the 5th level. But today i found this video on youtube that even makes me feel bad by simply looking at it.
It’s taken by some guy on top of the Burj Dubai at 818 meters and the tower is wobbling…

My current project involves some jQuery code.
I needed to alternate the background color for a html table with subtables and i wanted to do it in javascript.

So if your table looks something like this, use my Javascript code to color the rows:

<table>
   <tbody class="Alternate">
        <tr><td>I'm a row</td></tr>
        <tr><td><table><tr><td>I'm a subtable for whatever purpose...</td></tr></table></td></tr>
        <tr><td>I'm a row</td></tr>
        <tr><td><table><tr><td>I'm a subtable for whatever purpose...</td></tr></table></td></tr>
        <tr><td>I'm a row</td></tr>
        <tr><td><table><tr><td>I'm a subtable for whatever purpose...</td></tr></table></td></tr>
        <tr><td>I'm a row</td></tr>
   </tbody>
</table>

Here’s the the JavaScript.
It’s a one liner, but i wrapped it for better readability

	//Nice trick to get zebra tables with subtables
	$("tbody.Alternate > tr").filter(function (index) {
                  return index%4==0;
				  }).addClass("Dark");

Finaly the CSS.

.Dark {background-color: green;}

I’ve seen this video linked on reddit today.
As some of you know, I am totaly into machine vision these days and this 3d tracing software that imediately caught my attention.

Think about putting your face into your favorite video game – the term “Headshot” needs to be redefined then.
