The Advance Snow Lab Can Predict More Accurate Avalanches

January 25th, 2009

If you’re being offered to do some researches, by studying the nature of avalanches, would you mind to risk your life on it? Well, you might say, “Why should I do it?”

Do you know, Ed Adams, a 58 years old civil engineering professor has traded in his dynamite for a more challenging approach! He has used a $2 million new snow lab, where it’s aimed at gaining a better understanding of how avalanches occur.

The National Science Foundation and the Murdock Charitable Trust funded the snow lab, where it has been named as “Subzero Research Facility”.

According to Adams, this lab will help the experts getting to know the avalanches and more importantly, the best and more accurate ways to predict them.

Avalanches are difficult to understand and hard to predict comparing to earthquakes, as they can be suddenly happened without even an early warning on it. According to the New York Times, there are totally 31 winter ski resorts should be pay attention with, 16 in the United States and 15 in Canada.

The new snow lab will allow Adams and his colleagues to set the artificial sun at varying conditions to form different structures of snow crystals. Beside that, they have carried out endless avalanches simulation tests inside the snow lab as well! [source]

You Can Be Totally Invisible With This Invisibility Cloak!

January 23rd, 2009

If you a big fan of Harry Potter series, then you must be very familiar with his invisibility cloak, where he uses it to hide himself from being spotted by anyone else (Although Alastor Moody can easily penetrate it by using the magical charmed eye!)

You might think that It is impossible to develop the invisibility cloak, as this stuff only exist in the magical world! Guess what, the scientists from Duke University explained how to hide objects from a dramatically extended range of wave lengths, and they informed that the invisibility cloaks for visible light could be done within the next six months!

It’s time to start the spinning work…

The Proper Ways to Prepare The Eagle Designs For Manufacture

January 21st, 2009

You have to prepare many multi-platform eagle designs for manufacture, but you have no ideas what to do about it?

Well, there are many ways to turn an eagle design into an actual PCB. One of the best ways is to save the eagle designs as industry-standard gerber files, where you can use the gerbers files to order a single prototype or in a full panel.

For your information, the toner transfer is the favorite choice of beginners to make a PCB, as the total investment in materials is minimal comparing with other methods. Most of the PCBs are made with the photo-resist process, since the photo process makes nice boards, but it requires a bit of equipments.

While some of the board manufactures, such as the olimex, can be used to make PCBs directly from eagle .brd files. Olimex requires a minimum order of one eurocard-sized PCB (100mmx160mm).

Here’s the simple process of Eagle Designs:

  1. Firstly, you’ll need to prepare the design;
  2. Secondly, create grebes and generic files that accepted by any PCB fab house;
  3. Thirdly, remember to verify the gerbers;
  4. Lastly, send the design for production!

The best and cheapest option you can get is to submit gerber files like the professionals, and the best part about it is any of the PCB manufacturers will accept gerber formatted design files without any further modification!
