this one uses a mouse trap and a toy gun bullet caps as the buzzer. the mouse trap is considered the switch. this is an outdoor alarm for the yard. it gives off a loud bang when the enemy walks by. nails are used to hold the gun caps in place. the placement of the garden stakes have to be placed on a walkway. when the alarmed is tripped a metal hinged pulls back. then that releases the trap turning the coil. the trap arm hits the metal caps creating the bang. this was very low tech.

this one was the most difficult how to alarm system ive seen. he uses a little welding tool. a 50v battery is used as the power source. this is a parallel circuit. the welding tool is used in place of electrical tape. a Duracell procell D battery i think is used. video and audio wires help transfer the sound throughout the house. this one looks more professional by the tools he used. this one is in series with the door bell when it s rung. the door bell helps set off the alarm as well. a mother board has all of the wires connected to it as the brain. everything was pure electrical no wires of anything.

this is a basic trip wire alarm. the materials needed are basic like electrical wire and a battery. He uses aluminum foil on the clothespin as a conductor. all sound devices don't come with wires attached. a complete circuit was made after connecting all of the wires. it is good to test the circuit to see if current flows through. a piece of paper was put inside the clothespin as the thing that sets off the buzzer. when the clothespin is closed it connects the circuit. the wood is used as a conductor also. when tripped the buzzer goes off. the piece of paper inbeyween the clothespin is equivalent to an open circuit.

blog 5

Blogger is a very enjoyable website. its like your creating your own web page with the things you like. I have been using blogger for the past 2 years and found out it is like Microsoft word but on the internet. You can customize your page with YouTube gadgets and pictures.  It is an easy way for you to write a paper and the teacher can see it fast because its on the internet. There is no need to print out papers or email the teacher. I really like the advanced design features of how you can color coordinate the page with the help of a template. the gadgets are like apps with a lot of them in the market place. the market place has all kinds of gadgets like calendars and pictures of your favorite TV show. I just found out that even though my old blog was deleted, the old post was in Google reader. When your blog is deleted it stays in the system for a day and in Google reader. It also allows you to blog about what you have to do. its your personal website to do what you want. It is a representation of how i am. That is how i designed my page.

First blog

A blog is a space that allows you to talk about anything you want. Your own personal website where viewers can come to read what you type. You call call it a internet diary. A blog is used as an amateur and when you become a professional who dialog science journals or articles. the privacy settings can be customized to allow your page to be seen by friends or the world. Blogger profiles let you connect with more people like you by how you customize your interest settings. The template designer let you create your page with all types of fonts, Background, and layouts. As an added bonus you can also customized the color of your links. when customizing your blog you can upload a photo from the computer or just paste the URL. you can never be away from your blog since now there is blogger mobile where you can post blogs from your cell phone. SMS lets you text photos and blogs directly to your blogger page. Blogger is fun and free.

AC/DC stands for alternate current and Direct current. AC/DC is a very broad field to work in as seeing that everything runs on electricity today. Resistors are essential to a circuits because they help control the amount of current flowing through the circuit. there are to types of circuits: series and parallel. A series circuit is the most simple out of the two. A parallel is the type used in house today because it allows the same amount current to flow through because it doesn't flow in one direction. A circuit breaker trips when too much electricity flows through. A circuit breaker can be reset. A fuse is a simple device that blows after the max current is met but cannot be reset. AC/DC can be used to troubleshoot electrical problems like hooking up a radio in your car.
