Master Alarm System

• intruder detection system

 

Project Description

• Construct a house built of acrylic and program the windows of the house using Scratch to activate to the motors of the Gogoboard to send the robot to investigate which window has been opened. A mobile intruder alarm system, complete with a live visual recorder.

 

• Susanna & Brian » Build the house and the base for the laptop measurements -- FabLab
• Angel & Takira » Interface Scratch program with Gogoboard through XO laptop
• Takira & Chavella » Program gogoboard to turn on motors and investigate windows

 

Using the GoGoboard, the project is to create a master alarm system to repel robbers. Our problem is theft, robberies, and fires (which have lately been common due to the weather that has been occurring). The GoGo Board will contain a heat sensor that will detect when a fire is present then the sprinklers will activate according to the heat sensor on the board. The sprinklers will then activate and then spray water on the present fire, protecting the house from any damage and/or further damage. For the theft and alarm system, we will outline our project in Scratch, creating a virtual draft version of our house using basic commands. We will have resistors on the windows, stating whether or not which certain windows are opened. This would tell the occupants of the house where the thief has entered the house.

 

 

 

Susanna will also be keeping day-to-day work-done entries for the project.

Underwent intensive brainstorming on how we could encorporate this into something new that isn't already on the market. Research shows that many different alarm systems already have a variety of different securities, down to cameras, fire, and burglar alarm systems. Brainstormed ideas for an automated robot similar to the vacuuming robot to go to the source instead of having just the system notify the owner, would actually go to the breach and solve the solution.

Draft made for the project completed: descriptions of the pre-final draft: cardboard walls, made three walls, excluded back door wall, have two walls with sides, windows to be fabricated depending on measurements, house to be fabbed in acrylic based on measurements of the sprinkler and fire alarm system, Chris helped with the plywood plating on the bottom of the house to support all the walls and all the sides that stand that are press-fit. Wall 2 had a cut error, fixed with tape, verified our measurements are correct and went on to creating back door. Tape temporarily used to secure down all walls of the house and the front wall down onto the plywood plating, acts double as the floor and as the support for the entire house. New measurements made, house needs to be slightly enlargened, project exposition today before the real thing on the 15th. Draft house fabbed and completed, verified all measurements are exact and no errors are made, slot needed on wall 2 not needed anymore due to the fact back door wall is knocked out so that viewers may see the room and house on display with the other modules that will be presented inside the house.

Sharted on the centrifugal water system, got a submersible pump from Chris and created a second version sprinkler using the submersible pump instead of the centrifugal pump. Using straws and a balloon we're going to manipulate the water pump through an outside source. Remodeling the house using the new measurements of the submersible / centrifugal pump, new outline to be made for the house in acrylic or plywood due to the fact that the cardboard will melt if water is splashed on the project or it will catch fire due to the fire simulation for the thermister on the model for the heart sensors.

Today Ed and Geoff gave feedback on our sprinkler system. They said that we should scrap our initial design and go with the more efficient model of the centrifugal pump instead.

Working on the different sensors on the GoGo Board. Also working on the motors on the GoGo board to react with heat (tested with human breathing). Tests are successful on the GoGo board, resulting in positive feedback and continuing procession into testing with the GoGo board. Group members learned the commands for the GoGo Board, found they are similar to the commands in Pico and Scratch, helping with the programming. Online manual used for instruction in the programming of the GoGo Board heat sensors.

 

Wednesday, July 23, 2008

Tested the sensors for the GoGo Board. Heat sensor on the GoGo board works successfully, #3. Began on the Scratch Virtual House using arrows and commands for the windows on the house. First draft will use the keyboard but will later soon use resistors on the GoGo board. Beeping testing in progress. Coding in progress.

Looking into more research on fire and theft systems on the internet as background research for the master smart ho use. Successfully created the 12.5% version of the original 2 ft. x 3 ft. x 2 ft. model. Decided to make a large bottom press-fit and glue-gun'd bottom platform for the house. Solder done for the GoGo Board Monitor. Programming still in process for the GoGo board. Scratch portion begin. FabLab end for now, final product used for ShopBot. Draft done for schematics, draft (small version) done for FabLab house. Programming being done on the GoGo board.

Researching different fire and theft systems on the internet to do background research for the project, learning how the different systems work and how we could encorporate the project into making it perhaps more affordable or more versatile. Created first draft schematics regarding the layout of the house and the placement of the Scratch Boards, Gogo Boards, and the sprinkler for the fire alarm and theft system. By Susanna.

 

 

 

 

Thursday, August 7, 2008:

Finished programming gogoboard to respond according to the heat resistance of the thermistor. Once the thermistor reads a temperature of less than 75, the gogoboard triggers the motor on for 5 seconds. The motor turns a gear that is connected to a water pump, and the water pump is then rotated which allows water to come out and extinguish the flames.

Fires in residences have taken a high toll of life and property. In 2005 there were:

 

 

 

Low Cost

 

At the present time, cost of a home sprinkler system is targeted at approximately $1.00 to $1.50 per square foot in new construction. It is hoped that the cost will decrease as the use of home fire protection grows. It is also possible to retrofit existing homes with sprinkler systems.

Small Size

 

For residential systems, the sprinklers will be smaller than traditional, commercial, and industrial sprinklers, and can be aesthetically coordinated with any room decor.
