9. Associated Problems for Hearing Impaired: awareness of caller - door bell / knocking! telephone ringing television / radio cooker alarm smoke alarm intruder dog barking Analysis, Research and Investigation All sound based

10. Alarm integrated into TV Remote Control Analysis, Research and Investigation

11. My Design Brief Design and manufacture a device which will signal to a hearing impaired person that someone is at the door. An output light will indicate when someone is at the door. The device will also include an alarm to indicate that an intruder has entered the house. Analysis, Research and Investigation

12. My Specifications Analysis, Research and Investigation 1.The device should be operated by a normal door-bell push button 2.When the button is pressed the LED will flash until the device is reset 3.It should be easy to change the battery 4.The product / device should also hold a TV remote control 5.I should be able to make the project in the Technology room 6.The electronic parts should be visible and accessible to the examiner 7.The product should be strong and withstand sudden shocks 8.The product should be environmentally friendly

17. Design Ideas & Selection of Optimum Solution Design Idea 2

18. Design Ideas & Selection of Optimum Solution Design Idea 3

19. Optimum Solution I have decided to select idea 1 as the design I will make. I will make the last version where there is a housing to contain the circuit as shown below in the sketch. Design Ideas & Selection of Optimum Solution

20. I chose this idea because: It does not have too many parts All the parts are quite big so they will be easy to make Acrylic is easy to shape and bend A light will flash if an intruder enters the house Another light will flash to show someone is at the door It contains an electronic system It will hold a remote control Design Ideas & Selection of Optimum Solution

21. Circuits Outline how circuit works Pros Cons Design Ideas & Selection of Optimum Solution Circuit 1 Circuit 2Circuit 3

22. Design Ideas & Selection of Optimum Solution Optimum Solution My circuit design will use a combination of circuit 2 and circuit 3.

23. Design Ideas & Selection of Optimum Solution I chose this circuit because: It will show when someone is at the door & when the door is open. All the components are in the technology room. I can use the CNC router to make the PCB board so soldering this circuit will be easier than using strip-board. I have used push to make and push to break switches before so I am familiar with how they operate.
