100 Experiências prá Malta Jovem! E o David, agora a cores, Raspi com o dobro da memória, etc.

Para as Escolas, nada menos que 100 Projectos, para os Alunos...
É bom!

100 Awesome Engineering Projects for Kids

By Kristie Lewis
Engineering and fun aren't always two things that kids naturally associate with one another, but there are hundreds of ways to make engineering, physics and design fun and challenging for kids. Here are 100 great experiments that will let kids construct, play, learn and grow, all while they study the fundamentals of engineering.
These projects focus on the basics
of motion, force and other essentials of physics.

O Scanner 3D David não pára, e vem agora, numa nova Versão, com texturas coloridas...
New DAVID Version 3.5
Dear DAVID Friends,
We proudly present DAVID 3.5 - the best DAVID ever! ;-)
In the last months we have been busy implementing some great improvements:
  • Color texturing for SL scanners even with monochrome cameras, like the SLS-1. Real color, no tricks! It also performs white balancing, so you will get realistic colors on your 3D models.
    These have been captured with a monochrome camera (SLS-1):

O Raspberry Pi duplicou a Capacidade de Memória, o que vem aumentar ainda mais o seu interesse como Plataforma de Ensino de programação, e tudo mais o que se lembrarem:

Raspberry Pi Model B RAM doubled

James Holloway

Apparently in response to Raspberry Pi enthusiasts calling for a more capable addition to the lineup, the Raspberry Pi Foundation has today gone one better and doubled the RAM available in the existing Model B unit to 512 MB, without increasing the asking price of US$35.
In a blog post published today the Foundation implies that the RAM increase transforms the Model B into a viable general purpose computer capable of running "multiple large applications" at once.
There's good news for consumers who have ordered but are still awaiting their Model B Raspberry Pi delivery: they will receive the 512-MB variant without having to take action. A firmware upgrade enabling users to access the additional RAM should be released in the next few days.

Removing Tar from Fiberglass
audreyobscuraI have just begun the restoration process of my tiny fiberglass trailer. When I pulled the windows off of the hull, there was this tar-based weather stripping sealing the window from the elements. I knew that if I was to replace the windows at any point, I would have to replace the weather stripping too, and the new weather stripping wouldn't stick to anything besides a pristine-clean surface.

I removed what I could with a razor blade and a putty knife, but there was still a thick layer of black, sticky residue remaining. I went to the hardware store and found a product called GooGone. WEARING GLOVES, I put some the solvent on a paper towel and rubbed an ample amount on to the surface of the hull. I allowed the solvent to set for a few minutes before wiping it off with another paper towel.

(Note: I am using very heavy duty shop paper toweling)

The GooGone took off, or kind of melted, most of the tar. The small amount of tar remaining cleaned up with lacquer thinner.

In summary:

4)Lacquer Thinner
