Our Sun in 3D

STEREO Sun

Another link sent to me by secret agent Greg a few days ago. Its a space mission to send two probes in an orbit around the sun that will enable us to see the surface of it in 3D. On Earth you can’t do this very well because you can only get so far apart and when your at that maximum distance you have a whole lot of distorting air between you and your object of observation. Once these satellites are in place it will allow CME (coronal mass ejections) and other particle emission events with depth. Why is this a good thing? Well it will give us a much better chance of preparing for the problems that often occur when the sun has a little ‘gas’ and we all get washed with extra radiation. That can cause communications blackouts, power failures in big cities, satellites to die. And if your living in space or just visiting (think airline crews) it can be a health hazard. I for one can’t wait until images from these guys start showing up on Astronomy Picture of the Day.

Robot Magazine On the Stands

Robot 

I’ve been reading through the premiere issue of ‘Robot Magazine’ and have nothing but good things to say about it. Anyone that has an interest in the growing area of hobby robotics needs to read this publication. No matter if you have a LEGO Mindstorm kit and want to get some ideas, a new VEX robotics system, or are building a ‘Robo One‘ classed robot there is going to be something in this for you. The lead story of how the Mythbusters built their own PackBot out of the new VEX Robot System is a great read. First class stuff!

Project Plowshare Book

Nuke

Greg sent this to me yesterday. I have read about Project Plowshare before, a good idea except for the radioactive leftovers you get from detonating nukes underground. I’m looking forward to reading this book.

Geography professor writes first in-depth account of scheme to engineer with atom bombs from PhysOrg.com
What would you think if someone told you that not so long ago, the U.S. government, led by gung-ho scientists, seriously considered exploding 300 or more atomic bombs to blast a sea-level canal in Panama? Or up to 764 in northern Colombia? []

 

The RSStroom Reader

This is a sweet conceptual item (BTW, it’s amazing how many people can’t figure that out!). The idea it that as your sitting doing your business the RSSstroom reder is printing up your favorite feeds based on your biometrics. Just what the guys at Homeland Security need to keep up on top of things! If this were a real device I can see it being a popular accessory for the uber cyber toilets in Japan.

DIY Line Following Robot2

 

 There you go, a fantastic DIY project that involved LEGOs, electronics, and robotics.

As any good engineering project goes, we will start out with a problem and a solution. The problem is going to be to build a Lego robot with sensors, a motor controller, and a microcontroller that 1. Follows a black tape. 2. Upon reaching the end of the tape will pause for three seconds. 3. After pausing for 3 seconds will return back to the starting point.

This reminds me of my first robot. I had just about the same setup as he does except I had touch and IR sensors connected to a Basic Stamp all on a LEGO body. I used a hand built H-Bridge to drive the motors and not a 2998. It worked OK except the motors were geared wrong and it went far too fast. After smacking into one too many walls I took it apart and started on another project.
