Liddup is Litten Up with LEDs

Have you ever wanted a cooler cooler? If so, Liddup is for you.

It has lights in it that make everything glow. Not only does it make parties even awesomer, but it saves hours of countless rummaging to find something you want. Okay, maybe it would just save you five minutes.

The creators ran through 200 prototypes. But there work payed off; the cooler can allow up to 40 hours of light.

What a cooler cooler!

Internet Minute

Did you know that six Wikepedia articles are published every minute? Or did you know that people buy 83,00 USD worth of things on Amazon every minute? 694, 445 search queries happen every minute. And 50 WordPress downloads happen every minute. Wow.

Kinect Fusion Makes 3D Modeling Easy!

Released in 2011, the Kinect Fusion for windows has just gotten an update. It can now make 3D models on your computer! These models can be used for many things such as augmented reality. It could also take 3D measurements.

It works by taking a lot of pictures and depth readings, then modeling them into a 3D model. It provides much more detail than if it would have just taken one picture. You can make a model of the whole room you are standing in, just by moving the sensor around.

The future of special effects will probably be impacted!!

New UAV Navigates By Bumping Into Things

A future version of AirBurr.

A future version of AirBurr.

Have you ever seen a fly bumping into a wall to navigate around? Picture that fly made of metal, being round, and having a rotor on top, and you have the AirBurr.

The AirBurr has a carbon shell, which keeps the crashes it makes (from trying to navigate) from harming it. When it gets knocked down, it can get up with four retractable legs. Once someone pushes the legs in again, the AirBurr resumes flying.

The AirBurr has four photosensors, to help it to seek out light sources. Unlike some robots, it learns from its crashes. For example, if it crashes in one place, it won’t crash there again.

It is made by the EPFL. For more information click here.

How to Copy all the HTML of a Webpage

In my last post, I showed you how to delete all the content of a webpage. Know, I will show you how to copy all the HTML of the webpage.

WARNING: The content of a webpage is usually copy written. You can’t copy all of the HTML, and upload it to a server. If you do, the original website may take legal action.

First, (like last time) you will need to open up Google Chrome (this trick might not work on other browsers). Once it loads, type in a webpage address, and wait till it comes up. Then, right-click on it. A drop-down  menu should come down, and click inspect element on it. Like last time, you should see a lot of code.  Right-click one more time, and press copy as HTML. Paste the HTML into a Notepad document, if using Windows. If using a Mac, open up TextEdit and paste it there.

If you are learning HTML, you can look at how all the code makes up a site. If you want to make any changes, save the file as a .html file, then search it on your computers finder. Even if you aren’t learning HTML this is a fun activity.

How to Delete All of The Content on a Site (Then Get It Back)

This is a  neat trick I stumbled upon while previewing my website. This trick definitely works in Google Chrome, but it might not work in other browsers. Also, this trick makes it so only your computer doesn’t see it. 

First, open up your browser and go to any site. Then right click on any word. You should see a list of options. Click on the one that says “Inspect Element”. You should see a lot of strange words. This is called HTML (hypertext markup language), and id the language every website is written in. To make the content disappear, select a line of the HTML and press delete. Keep doing this until all of the content is gone.

To get it back press ctrl+r on Windows, or press the refresh button. On Mac, press command+r, or press refresh. Another way to do it on all operating systems is to close the site the re-open it.

Pov: The Wonderful World of Illusions

Have you ever saw a flip book and experienced how the pages  seem to make up an animation, even though they are just flipping very fast? If you have, you experienced Pov. Pov isn’t the name of a brand or product; it just stands for persistence of vision. What that means is that your vision can only see things so fast, and that it makes the illusion it is moving.

Animation by Jan-Eric Nyström, Helsinki, Finland

As an example, Pov is used for the animation to the left (to see it, click on it). It is licensed under creative commons license. For information about the creative commons license, click here. The animation is made up of many frames, going from one to the other very fast.  Online, people usually put images like this in GIF format (instead of JPG or PNG).

To demonstrate Pov, you can make a flip book. You can make one by:

  1. Cut 5 sheets of paper into quarters.
  2. Draw something on the first sheet, then draw something slightly different on the next one. Keep doing this until you have all the pages drawn on.
  3. Staple them all together.
  4. Flip through them. You should see an animation!

That is only a simple way to demonstrate Pov.  Crayola used it in its digital light designer. With that product you have a stylus where you can draw on a dome. How it works is complicated. A simple explanation is that there is a ring of lights that spin round and round. They are hooked up to a computer chip, which controls the ring of lights. The stylus is equipped with something (probably an infrared light, like whats on your TV remote, but I don’t know) that submits a signal to the dome. The stylus’s signal, draws the line. That is a simple explanation of how the Crayola Digital Light Designer works.

There are still other things Pov is used in. If you search Amazon for “POV kits” you can find some kits you could build that create coll illusions!
