Week 1 Narrative
I receive my project(Electromagnetic drive) this week, I spoke to my teammates, and together, the possible changes that could be done to make the project more interesting were brainstormed. Since I don't have a good bag ground in electricity, I planned to make a some researches before the next meeting with the my team on ohm, watt, capacitors, volts, and electromagnetism. I will do so in order to also see how they are related, and see how I can use it to have the project be more successful. Before I do so, I planned to read what the other group did, and extend my ideas on how I improve it.

My Second Task
For my second task, I started by looking what the group before me did. I learned from them that copper is the most electronic conductive metal and that makes it a good option to use as coil for the electromagnet. After I read all what they did, I went on internet and searched for volts, and I found a tutorial were it was briefly explained, and from that I found out an easy way to remember it, which is the pumping pipe, in fact I figured out that by increasing the pressure of water flowing out of a hose, more water will come out of that hose, that is exactly the same with volts and current. More voltage will generate more current, and less resistance will lead to more current, and this applies with the pump as well(If the diameter of the hose is increased, more water water will come out of the pump). After that, I started looking stuff on Electromagnetism. I found that electromagnetism can also be called magnetic of current which means that a current flowing in a wire produces a magnetic field around it. After that, I looked up some tenets of the electromagnetism, I found that for in a straight coil carrying current, the magnetic field is stronger if more current is added, and it becomes weaker if the distance it has to traveled is increased. I also learned that if I want to find the direction of the magnetic field, I can use the "left hand" rules. I also looked up the principles for a magnetic field due to a circular coil carrying current, and I found that the magnet is stronger when it is passed through a circular coil(This means I may want to use it for my project than the first one).I found that by increasing the current going through the coil, the magnetic field will increase, and it will decrease if the radius of the coil is increased. After I finished with the magnet, I went to the capacitors. I learned that it is an electronic device use to store charge,and that they are in most of our electronic circuits, and that they are various types of capacitors which can be found under capacitor types. I end up looking capacitors networks in series, and capacitors networks in parallel, and I learned that in parallel, the total capacitance is equal to the sum of the capacitance of each capacitor in the circuit, and in series, the total capacitance equals the sum of the inverse of the capacitance of each capacitors in the system. This means in series you store less charge, and at this point I asked myself why will people use it. And after some researches, I found that it is sometimes done because capacitors have maximum working voltages, and with two 900 volts maximum capacitors in series, you can increase the working voltage to 1800 volts. Now that I increased my knowledge on the materials I will be working on, my step will then to use what I have learned.--Stivi10 (discuss • contribs) 03:57, 24 March 2013 (UTC)

Week2 Narrative
Before the spring, I met with my team, I showed them what I have been working on, and my researches. It was decided to include the switch in the system in order to put the generate the current.

Week3 Narrative
I then went home, I started looking at how to make coil guns, I watched a bunch of videos, and from those I learned that if I am wrapping the coil, that I have about 80 to 90 turns otherwise there will be too much resistance, and that will lead to less current inducted. For the materials to get started my team is only waiting on the wire that was ordered the week before the spring break, so normally on the next meeting with my team, it will possible to start building and shooting!

Week4 Narrative
Back from the spring break, my team got the wire ordered, we started to find how to charge our capacitor before we get to use it. Couple of attempts were made before I suggested that we should leave the capacitor charge before measuring its voltage. The result changed after the team did so, but not as I wanted, so we went online and looked a video on how to do it. I went home I looked up how to charge a capacitor, and I learned that it depends on the time constant which is a time delay between its input and output when a Voltage is either continuous, (DC) or alternating (AC) is firstly applied to it. So I figure out that we should take this in consideration when charging the capacitors. Also, I learned how to measure the capacitance of a capacitor, so now I am just waiting the next and last meeting with my team to propose what will be the next step for the next group. Finally, I worked on the CDIO page for project two.
