High-Speed Data Link Made from Laser Pointers Works Where Wi-Fi Won't

Wi-Fi isn’t always practical--in places like hospitals or labs, for instance, where radio transmitters are prohibited--and physical USB cables can be slow and cumbersome as well. Engineers at National Taipei University of Technology have built a low-cost, easy to implement optical setup that can beam data's across the room twice as fast as USB 2.0 technology using conventional laser pointers. This only cost about $600 and  build and employs the green and red laser pointers for conference rooms. By replacing these batteries in the lasers with a power sources it can switch them on and off rapidly about 500 million times per second rapidly. A two-laser rig can beam a billion bits per second across roughly 30 feet. If you combine these, the signals roughly double the data rate of USB 2.0 or Wi-Fi, and could link together systems in portable labs or medical centers, or simply make it easier to set up networks in places where radio signals might interfere with other equipment.

A Massive Robot Dog Made all from Scrap

This event is about these steampunkish dudes at Mutoid Waste company who have been in the lap of everything we call scrap, making stuff that is beyond even the best sitting in the helm in factories. This picture right over here shows Larry the robotic dog made out of scraps and  is their latest induction to crawl through the gates of the workshop and onto the busy streets of London, breathing fire out of its metal hood with each step forward. The robotic dog has a Citroen 2CV engine fitted inside the metal frames. This took the Mutoid Waste company at least 4 weeks to build and it took a lot of hard work and determination to build it. For the eyes, Larry has a radar detecting device from an airplane scrapyard and some industrial machines parts for the other body components.


This reminds me of when I was in school and we had to create a car using the material given and then we had to race them which is just like how Mutoid Waste company made Larry out of the material given without the racing part. It was really fun! I feel that Mutoid Waste company worked very hard to make this robot and that if they made a business out of this they would make a lot of money.

Autism More Common Than Previously Thought: CDC Report Shows One in 54 Boys Identified

This story is about the recent news about the U.S. Centers for Disease Control and Prevention estimates that 1 in 88 children in the United States has been identified as having an autism spectrum disorder, according to the new study released March 29. This takes place in the Unites States. Autism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behavior. These signs all begin before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood. I feel that autism is a very bad disease and that it is sad and that now even more of the boys in America are getting this. The people that don't have autism should be happy that they don't have it. Trust me you don't want to have it. This reminds me of our school, we have many autism students and when you see them you should not laugh at them but instead you should be say hi to them and be nice to them. How would you feel if you were a autistic child? You would probably feel left out and lonely. I bet you wouldn't like that!

When here about more people getting autistic I feel very sad and hurt. And then when I see people making fun of them I get really angry. So one of the solutions that I used was that I told that person that, that person was autistic and that you should stop making fun off them. Then I told them how they would feel if they were autistic! Then the guy went to the autistic kid and apologized to him. And now he plans on joining the autistic club. So for all the people who are out their you should read this article and before you start laughing at autistic kid think about how you would feel you were an autistic kid.

States of Matter Lab!

These are examples of the candles we used!

During the past week we have been doing an abundant amount of labs. We successfully did these labs, Marshmallow lab, Candle lab,  Observing Changes in Matter Lab, and finally the Pouring Gas lab. In this essay I will explain to you what all these labs are. First we will talk about the Candle lab. During this lab, we lighted a birthday candle and observed the changes. But, before we lit the candle, we used some of our senses to observe the physical property of the candle. I first noticed that the candle was very tall, thin, rough, and that it was made out of wax. Mrs. Rousseau lit the candle for us so that we did not start off and fires, then we quickly saw many chemical changes. The candle showed heat, light, and burning wick is turning black. After a little amount of time we discovered two physical changes that the candle was melting and shrinking slowly and slower.

These are examples of some the marshmallows we used!

The next lab we did was the awesome Marshmallow Lab. We did this lab on two different marshmallows, one huge one, one small one. We tore the small marshmallow into two pieces, which was a physical change. Then we ate the small marshmallow and we jotted down how it tasted. I thought it taste scrumptious and sweet in my mouth. The next step that we did was using the Bunsen Burner and that large marshmallow. First, we put the marshmallow over the Bunsen Burner to see what the outcome was. The marshmallow had changed from a sweet and scrumptious white marshmallow to a dark and black hot disgusting marshmallow! This was a physical change because it melted the inside of the marshmallow but was also a chemical change because it was burned by the fire. After the burning, the marshmallow went from a solid to a liquid and solid mixture. Out of this lab I learned that when we burn the marshmallow that it was a chemical change!

This is an example of the candles that we used!

Another lab that we did was the Pouring a Gas Lab. First we lit the candle to start the lab. After this my group mixed the water and the vinegar into the same glass. Then we carefully added some more of the baking soda into the glass. The reaction was quick that I could barely even see it. The liquid exploded and created a white foam to go up quickly and drop all over the edge of the glass. Then we all decided that this was a chemical change. Once the foam came back we slanted the glass over, but we had to do this without making the liquid fall, and then we held it beneath the flame. The flame immediately went out as soon as we did that. Out of this lab I learned that when mixing water and vinegar into the same glass and then add some baking soda it would create white foam.

This is a chart!

The last and final lab we performed was the Observing Changes in Matter Lab. In this lab, we implemented many diverse experiments to sugar cubes. We took a sugar cube and used our senses to examine it. We concluded it was small, white cube-shaped ,sweet. We took two of the cubes and decimated them. This was a physical change because the final outcome was still sugar. Then we took the crushed powder and dissolved it in water performing another physical change. The sugar was still their because we could still taste the sugar. If we could not taste the sugar, we would have noticed that the water had become less pure as it was before we dissolved the sugar in it. Next, we took the last two sugar cubes and put them into a test tube. We used a tong (are used for gripping and lifting tools, or which there are many forms adapted to their specific use) and put them over the Bunsen Burner. My group first saw a yellow liquid sprouting underneath the sugar that was precipitously turning brown. Soon the liquid changed into the color black and we couldn't see the sugar cubes anymore. We concluded that this was a physical change. After a few minutes we took a look at it again. It was bigger than it was before and it was black and burnt.

Procedure Lab!

On Thursday, in science class we  separated a mixture. Inside the cup were 7 mystery objects and our task was discover what were the 7 objects and state our procedure.We were allowed to use 2 graduated beakers, a funnel, a graduated cylinder, cup, spoon, magnet, taunts, paper. The steps to the procedure were:

 Step 1: First you should observe the cup to see what you are going to be touching. 

Step 2 :  Then pour the water from the cup into the graduated cylinder and when you pour the water, make sure that none of the other objects come out with it. Then use the funnel and pour it into the graduated beaker.

Step 3: After that observe the cup again and you will see something black. That is called Metal Filim. Use the magnet to pick up the Metal Filim and then put it into the one of the beakers. It might be hard but if you try your best you will be able to do it. Make sure you get it all out of the cup.

Step 4: Next examine the cup and you will find something white. Those are beans! Put that on the paper and let them dry.

Step 5: Use your pipette to extract some water from the container. See if any object has revealed itself by sight. 

Step 6: Now put your graduated beaker that contains the water and put it on the hot plate and be careful because the hot plates are real hot. Stay away from the hot plate and keep the paper away because it might cause a fire and we know you don't want that. SO BE CAREFUL!!

Step 7: After a minute or two pour out some the water out of the graduated beakers.This will speed up the process of the water boiling.Watch too see if there are any changes in the water. Mark my words" only some of the water".

Step 8:  Now identify all the different objects that you saw and have taken out of the cup. You should have been able to find 6 items. If not check back to see if you left a procedure out.

Step 9:  Finally pour out the rest of your water into the drain. and check to what you have at the bottom of the beaker. At this point, you should have found 7 different objects including the object at the bottom of your graduated beaker.

Step 10: Now since you are done you must clean up all your supplies and including the tray. Then recycle the paper, metal strips and the cup. After that get a cup and paper for the next class and put all the supplies in order. Now you are officially done with this lab!

Hope you had fun!!
