6. How common is burglary? Every 37 seconds a home somewhere in Britain is burgled. Every year there are over 1 million burglaries and attempted burglaries. 20% of households experience more than one incident a year. 13% are burgled twice and 7% three or more times. Between 1981 and 1993 burglaries increased by 137%. There was a decline through the rest of the 1990’s but which has now leveled off and 2002 showed a 5% annual increase. Aggravated burglary (where the occupiers are home at the time) rose 14% in 2002.

9. Questionnaire NoQuestionYesNo Q1Do you feel your home is secure ? 128 Q2 Do you fell that your doors and window could be more secure 164 Q3 Would you expect the security to be reliable yet affordable? 182

10. Questionnaire Continued NoQuestionYesNo Q4Do you fell having a security system would deter burglars ? 91 Q5 Would you feel securer in a home with security ? 100 Q6 Do you fell that the security system should be visible? 82

11. Questionnaire Continued NoQuestionYesNo Q7Would you what a security system that you control? 100 Q8 Would you want a security system that you can extend to out buildings ? 91 Q9 Do you want a system that is difficult to override? 82

12. Questionnaire Continued NoQuestionYesNo Q10 Would you want a system that the security code can be changed ? 82

13. My Conclusion From the questionnaire I conclude that the majority of persons questioned would like their property and out buildings to be better secure, however the driving factor that the vast majority want from their security system is reliability and more importantly affordability. Therefore cost would be the major factor. I have deduced that 80% of the people that I asked said that they would like the product to they want a system that the security code can be changed, this will be because they can change there pass code if they feel that there security has been compromised, this makes the user feel that bit safer.

15. Design brief Design brief My design will be to use a switch that will cover all access points to the building, such as doors and windows. It will consist of two contacts that when separated will set of an audio and visual alarm system. The alarm will sound and flash until you put a main key code into the main alarm box. The contact switches will be small to ensure they are discrete. These can be easily installed into door and window frames and linked internally throughout the building.

16. My final design brief My final design brief will be a baby bath water temperature alarm. This is because I have done some research on security in the family and one of which is on the children of the family. Within the family one child of the family is a new addition to the family. In this case the new bourn baby, many mothers with a new bourn take care of them as much as they can but when it comes to bath time some mothers do not know how hot the water really is. Many mothers try a method that they think is the best way on checking if the water is to hot or to cold. The average temperature for a baby to enter the bath is 37 degrees and a average persons temperature is 34 degrees which this is a big divergence between a baby's and a fully grown person.

17. Creativity (slide 8) Product Analysis Analyse in detail 2 products related to your project (probably 2 different types of burglar alarms, one fairly simple and one a little more complex.) Use the table on the next slide to help you organise the information. A simple system for the hotel room on holiday. A more complex system for the home.

19. Specification Feature describedReason for feature 1.The purpose of my product is to protect baby's from being burnt. the reason for this is because many baby`s are being burnt because of the parent or guardian does not know how hot the temperature of the bath water relay is. 2.My product will sense the temperature of the bath water is not to hot or to cold. This is because many of the parents do not realise how hot the water is. For there baby. And to fulfil the products propose. 3.My product will need to sense the temperature of the water. For my product to fulfil is primary propose. 4.The out put of my circuit will be a buzzer. So that if the user is doing something else at the time or is down stirs the buzzer will sound so that they can hear it 5. My power supply will be a battery.The reason for this is because it will be easy to buy for local shops and they would be much better for my circuit. 6.The voltage that my circuit will be run on is 9v.The reason for this is that it will work and it will be safe for the user. 7.Myproduct will have a on and off switch.So that the user can turn it on and off very easy and it can save some of the battery supple.

20. Specification Feature describedReason for feature 8.NO my product will not have a power indicator.Because you may have to buy a sertian types of battery`s for it to show up and it may take up more room in the design and may cost more. 9. The shape of my design will be in the shape of a life ring. Because they are usually go into the water and are also on the side of ships or on other on sea ships. 10. My circuit will be manufactured by polymer plastic. And by using pcb`s and soldering all of the parts together Because it is a easy substance to get plus it is easily flexible and is water proof as well. 11. I will ensure that my circuit will work and will be made well. So that the user will not be happy and have to return the item and about the product itself e.g. the three LED`s aren`t working and that it does not work in water.

21. Design (slide 11) System Diagram Show a systems chart to show possible inputs, outputs and processes. Show pictures of the components required for each input or output mentioned. Do not include combining inputs and delays if not appropriate to what you are designing – although you could use the columns to show that the response is immediate. (i.e. 0 seconds.) Delay before INPUT INPUT Combin e inputs? Delay after INPUT PROCESS Delay before OUTP UT OUTPUT Time delay between power on and input sensed? Delete these instructions from your table. List of possible things that could be sensed + images of possible components. More than one input that needs combining ? – e.g. AND or OR? Time delay after input sensed? List of possible ways that the output can be controlled. Time delay before the output is turned on. List of possible outputs ( include power indicators etc.) + images of possible components

22. Three circuit diagrams from the web This PCB circuit has 3 LED`s and has a battery supply and has nearly the same layout as my circuit has. Also it has 5 resistors but it does not have a buzzer. this PCB circuit has only one LED but it has a buzzer which helps with any one who has trouble hearing as well as that it has a latch switch so that it can be turned on and off plus an battery supple so that the circuit can work. Even though it is more complex than the first one and the second one. This PCB circuit has a buzzer not like the first circuit witch it does not have and has a latch switch as well so that it can be turned on and off plus it has probes to sense the temperature of the water a power supply so that it works as well.

23. Design (slides 12 and 13) Slide 10 – Ideas for the circuit Include 3/4 circuits that could solve the problem: ◦ Picture of each circuit – from internet, hand drawn and scanned in or from circuit wizard. ◦ Brief description of the circuit saying what does in terms of what it senses and how it controls its outputs. ◦ How well it could it solve the problem? ◦ Choose one circuit and give your reasons for choosing it. Slide 11 – Development of the chosen circuit Build your chosen circuit in circuit wizard ◦ Show annotated screen shots of the circuit being developed – component values being changed to fine tune the way it works (especially in terms of timing delays etc.) ◦ Show annotated screen shots of the circuit being tested to show that it will work and that it will solve the problem. ◦ Include a video of it working using “Blueberry FlashBack Recorder for top marks. It is important that the screen shots and video show it working so that it is clear that it solves the problem.

24. My chosen circuit This is my chosen circuit is along the same lines as a goldey locks circuit. I chose this because it has the same function as on what I want my product circuit to do. I have desgin in a swich near the battery so that the circuit can be turned off and on without having take out the battery. This means that you can save money by not wasting battery power when you don’t need to, this will save the user in the long run.

25. My circuit working

27. Design (slide 14) Development of the PCB Show the stages of the development of the finished circuit into the final PCB You must show at least 3 stages of development. Each stage must be annotated to describe the changes and the reasons for them. The final PCB must be shown including the off board components and the connecting wires – it would be a good idea to label this final stage. The list of components must be included – images of the components to be used could get extra marks. (from earlier in the project?) Include a video of it working using “Blueberry FlashBack recorder for top marks. It is important that the video show it working so that it is clear that it solves the problem.

29. Making (slide 15) Planning for manufacture Use the table below to describe how you plan to make your circuit. Use the information and pictures of equipment on my website to help you.website Description of ProcessTools/Materials required Tips for success Design PCB and create mask Cut board to size Expose Mask and photoPCB to UV Develop exposed PCB Etch PCB Drill holes in solder pads Add resistors Add capacitors Add transistors/thyristors Add Chip socket Add off board components Add chip to socket Delete any of the processes that don’t apply You need to add detail to this column for each process

30. Making (slide 16 to 18 - approx) Manufacture of the circuit Include photographs to show the stages of the making of your circuit Annotate each picture to show what is happening. Highlight any problems that were encountered and what you did to solve the problem or anything that you changed as the circuit was constructed (i.e. what is different to what you planned. This evidence is an important part of the mark scheme. In addition: ◦ You must include a clear photo of the whole circuit including the off board components and the connecting wires. ◦ You must include a clear photo of the top side of the PCB showing the components. ◦ You must include a clear photo of the underside of the PCB showing the soldered joints. To ensure the marks for problem solving are gained it might be best if the changes made and the problems encountered are summarised at the end of this section.

31. Evaluation (slide 19) Testing your circuit Show a step by step plan that can be used to test your finished circuit. Write it as if it were for a person who does not know how it is supposed to work. Tick of each step to show that the circuit works. Provide a video showing it working so that it is clear that it solves the problem. Use Blueberry Flashback Recorder). Evaluation Describe what went well and what did not go so well in the manufacture of your circuit ◦ Consider the development of the circuit and the development of the PCB ◦ Consider the actual building of the circuit Could it have been made differently? – alternatives? Could it have been made better? – how? Compare what you did to the steps of your plan See table on next slide as a suggestion.
