Link1: How to Fabricate a Remote- Controlled Toy Plane For Beginners
Though i have done research for building a a flyinh object, I can not come to conclusion on what to type into google for a proper search. I treied many things, like how to build a flying object, how to build an airplane, do it ypurself airplane, but they were either paper airplanes, or real life airplanes. So I found this first link that would probably give me an idea of what to expect from this experiment. The instructions tell me to start off with an ordinary plane, where I can start off by making it from ordinary thermocol or polystyrene. The body of it can be made from 1in sheet for the wings and a quarter inch for the wings and also a quarter inch extruded foam for the tail. The type of foam that could be used would be the one similar used for disposable plates. The wings designed should be allowed to stretch to a span of 30in and length of 24in. For the airplane, you can use any orndianry toy motor and recharchable batteries. The link says that it is better to start with a simple RC set without servos. The site also suggests to try a self made kit. Especially one suitable for beginners. I fell there is a beginner benefit from using a kit because the beginner will get the hang of it. Though research is still need to be done more. Let's see what other sites have to offer.
Link2: How to Build an RC Airplane (from scratch)
In this web site, i am allowed to create any design of my desire for the airplane. As i read durther on, I question myself will this really work but only experimenting will prove it. It looks reliable, and fun at the same time. I expect a good model out of this. The materials needed are as followed. Plastic or balsa wood or foam, engine and batteries. An engine will be a toughy though. you will have to buy the engine. You can choose from electric powered or gas powered engines. The gas powered engines can be 2-stroker and 4-stroke just like the car engines. For the electronics, it will consist of a transmitter, a reciever, a speed controller, and batteries. You will need to install control horns onto each of the control surfaces. Oncec the control horns have been installed, the metal connecting rods which connect the control horns to the servos muct be formed. After the ontrols horns are installed and their control rods are connected, the cervos must be installed on the airplane and attched to the control rod.
Link3: Foam RC Airplane
This link i suppose is one of the must informative ones i have necountered yet. It actually gives me the instructablles of how to make the airplane along with pictures. This is a really good duidance in my opinion. This airplane will be built out of foam. The full scale desing and template can be printed out at http://www.foamyfactory.com/. here would use the templates and draw them on the foam board and cut them out also cutting the slots. Here I am also informed that I can make a rudder for more advanced flying, though the simplest control hinge is made from tape. Using a jig saw, both ailerons should be cut at a 30-45 degree angle where the control surface meets the wing. to make the hinge, mate the control surface to the main wing body at the cut angle and apply tape, folding the control surface the other direction and tape underside of the wing and aileron. The wing should then be slid though the slot in the airframe, and apply glue to the wing, sliding in to place. The slots should then be cut from the elevator, then slide and glue. Next the servors will be installed. The length of the control linkages dictate where the servos should be mounted. Simulate the locations of the control horns then make an outline of the servo on the airframe, repaet the same thing for the elevator, and cut out the servo locations. A hot glue gun should be used to fic the servo to the airframe. Later screw down the control horns or hot glue them in place. A table saw sould be used to then cut out a slot in a block of wood to mount your motor on, pre drilling the mounting holes in the block, gluing the block to the airframe, and mount the motor to the block. Then you would just need to mount the esc, radio and battery. the battery should balance out the plane.

Door Alarm System
Link 1: Make You Own Alarm
There a possible ways of building a door alarm. This link shows how make a door alarm yourself. You can use spare items that are already around your house with addition of a few minor things needed from the hardware store. Things that are needed are as followed: Insulation, Flexi-Wire, Electrical Tape, 9 Volt Battery Holder, Electrical Buzzer, Clothes Pin, Knife, Thumb Tacks, and a ruler. First you are suppose to prepare the wires, where you have to strip a half inch on insulation of both ends of flexi wire using the knife. The insulation should hold the two wires. The 2 wires should then be attached to the metal connectors on the 9 volt battery holder. This should be secured with electrical tape. After, the wire sgould be connected to the electrical buzzer.. and both wires need to be connected to the joints of the electrical buzzer and be held securely with electrical tape.
To check if the buzzer works properly, you would need to connect the battery to the holder. IF the proper connections are made, the buzzer should go off, and if the buzzer does not go off, the wires should be repositioned. Once a buzzz is made officially, the batteries should be removed. Assemling the wires would consist of going down the flexi wire to about half a meter, and cutting one of the wires in half. Separate both of the wires that are within it, cutting only one of the wires. Strip down both cut wires with the knife. Opne the clothespin as normally and stick 2 thumbtacks inside the opening of the 2. this is to assure the buzzer will make noise once intact. another wire should be attached to the opposite end of the clothespin against the other thumb tack. The clothespin should then be closed and the batteries shoud be attached again.
Link 2: Super Simple Door Alarm
In this link, it provides the basics of building a door alarm system with using simple items. There are many ways to build a door alarm system. All are different design and some are uniquely or prfessionally made. What is unique about this it uses a smoke detector. The idea is to take a door contact used in alarm systems which will then be connected to a smoke detector, and yes an on/off switch should be included. The materials needed for this door alarm are wires, smoke detector, battery, magnet contact. The plastic that protects the smoke detector should be removed as well as the pcb from the plastic shell. There should be a little metal strip next to the led, this is the test button, or the contact area. the pcb should be turned upside down and find the contacts for the switch. Here a wire of 10cm long is needed, then it should be solder to one of the test button contacts and to the other. Two wires should be loose in the end and they should be connected to the switch. A hole should later be drilled in the smoke alarm lock and the switch should be able to fit and later fastened.
Afterwards the pcb should be back in place and the lock should be back on. The Loose end of the cable should then be connected to the door contact and put the switch to on. Test it out by opening and closing the door contact, and the alarm should go off. Fianlly install on door.
Link 3: How to make a Door Alarm
This links shows the process of making a door alarm even kids can use it. Its fairly simple and the materials needed are 2 insulated wires, 2 stripped wires, 1.5 volt battery, string 3-5 long, electrical tape, 1.5 volt mini buzzer, string type wooden clothes pin, piece of plywood 4in x 12 greater, and glue. A battery and buzzer should be placed on the wood, where the battery goes on the top right corner of the wood and battery on the top right. They should then be taped down with electrical tape. The clothes pins should later be wraped with non insulated wire (end of clothespin). The wires should touch when the clothespin are closed. Later connect one of the free ends of the wire around the clothes pin to a wore coming from the battery. The wire should then be connected around the clothes pin to the buzzer and the remaing free wire from the batter to the buzzer. The switch should be tested by opening and closing the clothes pin. The buzzer should make a sound when the switch is closed, and if not, the wiring should be checked. The piece of carboard (or any other insulative material) in the clothespin to seperate the wires. This is to keep the buzzer from not going off anymore when it clothes. The clothespin should then be glued to wood, and a string should be attached to the piece of cardboard beween the close pin. The other end of the string should then be attached to the door. The alarm should be place where the string is taut between the alarm and the door. When the door is being opened, the string should pull the cardboard out, setting off the alrm.

Reflection
Blogging is actually something I enjoy doing in my spare time. It's a hobby to me. Keeping personal posts or inspiring quotes/ images/ typography is actually something that has changed me as an individual. It's like a personal portfolio to me, well in my personal blog, I like to keep things updated. Especially photography, but seeing that there are many things you can tie a blog into is very useful. You can keep in touch with friends, or in this case for this class,classmates. It's a very good resource for classes use. This way you can keep in track with class instructions. It's also a good way to keep track of records. With the use of a blog it is like having an interactive class.

Good and Bad Design features of a Blog
Since I've been a blogger for plenty of time now, I have too encountered many blogs that are either poorly desinged or have too much going on it it. For example, a poorly designed blog would have a default background or extremely small cursor or texts. As for the Overly desinged blogs, the text is either huge, too many colors in the page, animated backrounds or gif as a backgorund, or animated cursor and my least favorite, music being played in a blog. This not only distracts me from reading a text post or observing a picture, but also makes the blog not look decent. I would understand if it was a personal blog, but seeing if it really was a personal blog, would anyone enjoy such amatuer features that were put in the blog? A huge disturbance that approaches most readers is the background interrupting with the text. I have had several experiences where I would get lost in somone blogs because I couldnt find links. I also couldnt find proper navigation buttons. I'm not very familar with the use of blogger. I'm more informed with designing in tumblr and html codes a bit. Hopefully within more experience with blogger i could change certain features to make the blog a bit more decent.
Electrical Systems Module
Electricty is the flow of electrons. Electrons spin in an orbit around the center core of an atom whereas the center core is comprised of protons (positive charge) and neutrons (neutral charge). Electrons have a negative charge and balance out the positive charge of the protonsand. When an outside force causes the number of electrons to unbalance the charge of the protons, the electrons will split off the atom and look for another atom to balance out. Electrons will continue to move and an electrical flow will exist if the imbalance is kept up. The flow of electricty can be measured in the use of amperes.
Some materials also have more resistance than others. For example, those that have high resistance are said to be insulators. (rubber). Very low resistant materials are said to be conductors (copper). Based on the observations made in the module, there are numerous of things I can use from the module in real life.Whether is for home applications or for personal applications such as powering your car or alarm system.

Blogging Summary
I've been a blogger for a good amount of time now. Through my experiences with blogging, I have learned many things about blogging and how it has changed media communications. Many of bloggers these use blogs for journalism, memos, breaking news, or just for personal use. There really isn't a limit to rules in blogging and the things that can be associated with in one. You can create your own designs, write your own thoughts, have a class lecture and it goes beyond. Blogging can bring many people together to keep in touch through your posts.
