Techie Club, 11/19/14
Today in Techie Club we learned about micro controllers and microcomputers. We watched a presentation about what micro controllers are, and they are small objects that can be used to program other objects. Microcomputers are just computers that are small, like the Raspberry Pi. Also, micro controllers can only run 1 program. The micro controller we got to work with was called Arduino. It comes in various sizes, and one is even as small as a penny! You can connect wires and other things to them and make them do all kinds of things, so in a way it’s like Lego Robotics. You can connect the parts to a breadboard, which is a board that allows you to connect different electronic pieces. We then got to help program it, which is done with a computer and is fairly easy. The program we worked with made a light blink, and we played around with it to make it go faster and a different intervals. It was really fun!
P.S. I think I might do something with the Arduino at TechieLoka!

Peanut Butter and Jelly
Today in techie club we had to write the steps to make a peanut butter and jelly sandwich. It was so hard. One of the volunteers went in the front and we had to tell him how to make the sandwich. They had to be more detailed than I thought. For example the step for just opening the peanut butter were: 1. Put one hand on the bottom of the jar. 2. Grab the blue part at the top. 3. Turn the blue part counter clockwise 10 times. 4. Grab the blue part. 5. Lift up the blue part. 6. Put the blue part on the table.
The whole point was that when you program the computer you have to be detailed. Each step is called an instructions and all of them together is an algorithm. There is a computer language too. That is the only language the computer can understand.

Today we did scratch (look at the title.) So we started off by making are person whirling and changing colors. Then we did we have to click a color on the screen to change what our sprite looks like (sprite is a character in programming words.) So I’m done can’t wait till next week.

The Internet of things
Today, we learned about the internet of things. At the beginning of class, we watched a short video about different types of sensors and how in the future, there might be a lot of sensors in a house that will figure your ( depending on what type of sensor it is ) temperature, emotions, hunger, and heartbeat. There might even be refrigerators that will tell you what is in it, and what you can make with its contents! After that, we broke up into groups and wrote down ideas for things in the future that will use sensors to figure things about you. Our project idea was a virtual reality helmet.

Today in techie club we learned about HTMLs. The first one is <h1> you type that in to make a heading. You have to close the heading by typing in </h1>. You have to close every HTML that you make. The next one is to make a paragraph. To make a paragraph you do <p> and close it with </p>. You can also make things bold, italic, and underlined. Bold is <b> and closed with </b>. Italic is <I> and closed with </I>. Underlined is <u> and closed with </u>. You can also add a font by using <font>. You have to put a color too for example <font=color”red”> would make a word red. You have to put <body> at the beginning of everything. At the end you have to put </body> because you need to let the computer know that everything you wrote is the body. You can also add pictures. To add pictures you look up a picture and copy the URL which is just the title. You then put <img src=paste URL here>. Today was our first day of coding and it was really exciting. I can’t wait to see what else we learn.

Bits and bytes
Today we learned about bits and bytes. The bytes are the things that save the data in the computer. The bits are the on and off switches on the computer or other of such type. We even learned how to contrast numbers into letters to spell words. For example we spelled out the word ”zebra”. Now that we know how to contrast the numbers into letters, it will be very helpful for life. We can also resort to the data saver bytes when we need to see some of the most important stuff. just from this, I want to learn even more about computers and how they work.

The Start of App Development
Today, we started making apps. First, a volunteer talked to us about apps. He said that the difference between a mobile phone app and a computer app is that a computer uses a mouse to click on things, but on a mobile phone app, you have to use your fingertips. Another difference is that a computer needs the internet to see a public application, but a mobile phone app does not always need to be connected. He also said that before an app looks good, it needs a wire-frame, which is a foundation for the app. He said that we would be drawing a wire-frame today. There are two languages that apps are coded in: Objective-C and Java. After that volunteer told us things about apps, another volunteer shared a demo with us on his phone. It was a weather app.
After both volunteers shared, we got two transparent pieces of paper with a mobile phone outline drawn on it, and two regular pieces of paper with the same design. We also received sheets of paper with examples and outline drawings of weather app wire-frames and symbols. We were to draw a wire-frame for our app on the outline of the mobile phone. When I saw that we would be drawing, I was really excited, because I like drawing. I, personally, did an extremely detailed wire-frame for a weather app, but not all did. I hope that next week, we get to continue on our app development and wire-frames, because (at least for today) it was awesome!

How the Computer Works
Today in techie club we learned about how a computer works. We learned that there are little things inside the computer called packets. When things like emails go through the computer they do not go in one piece. They travel in little pieces that I mentioned earlier called packets. We learned that a server is a giant computer that stores information. The internet is a giant network of these servers. We learned that these things called routers direct the packets to the shortest path in the server. We also learned that their are really bad things in the computer called viruses. They are tiny things that destroy the information that is in your computer. They can be really bad and can even lead to your computer not working anymore. There are also hackers who steal the information in the computer. Hackers can get into things like credit card information and other important things. So protect your computer from viruses and hackers.

After an incredibly busy summer (680 students in TECH CORPS programs); moving into a new office (stay tuned for details about our open house) and recruiting and training nearly 200 technology volunteers (all now sharing their time and talents in our afterschool and Saturday programs), you can imagine that we might be a little behind on our to do list.

to day we learned about css like
will change the font size. I think css is grate so tell me how is my web site going here is the link http://codepen.io/anon/pen/fACkc?editors=110 .

What is Happening In the Computer
Today in techie club we learned about how information travels through the computer. Almost all of the information would start at the keyboard. We learned that the processor is working all the time. I thought it was interesting how it does everything in one second.
We learned how you send an email. First, of course, you have to type in the email with the keyboard. Then, the keyboard sends it to the processor to process it. After that, the information goes to the random access memory(RAM). The RAM then sends the information back to the processor so the processor can give it to something else. That is the NIC. The NIC sends it to the other computer. That is one example of how stuff travels through the computer.

Today we played a game Peter Packet. It was about hackers, viruses, severs and routers. I learned a lot, I now know that a router directs packets to the shortest path. I also know that the internet is a giant network of servers.
