Introduction

Situation: A commercial company requires a dynamic advert for displaying their wares in a showroom/office etc. Design and make an advert, which includes electronics. Solution: I have a huge interest in cars especially up market sports cars like Ferrari and Porsche. I will design a 3D advert to advertise one of these models using a series of flashing L.E.D's and a car alarm. The Internet I can use the internet as the basis of my project. I can find out about different types off adverts and research Porsche. I can use it to contact different companies. Companies I can E-mail these companies for information on their products and how best to advertise them. Magazines I can use these to look for advert ideas for products. My Teacher My teacher can give me ideas on how to go about producing my project. Classmates I can survey my classmates on how they think best to advertise a car. I used many forms of information, which I have listed below and I would like to thank them for their cooperation. www.porsche.com Isaac Agnew Limited (A Porsche Dealer in Belfast) Below is a copy of the E-mail I sent to Isaac Agnew. Dear sir/Madame, I am currently studying GCSE Design and Technology at St. Louis Grammar School Ballymena and I would be most grateful if you could forward to me any information, which may be of use to me. ...read more.

* A battery must power the project. * The project must have an on/off switch. * All components and wires must be protected by heat shrink tube. * The project must be safe. * The project must not be an eye sore; it should be nice to look at. * The project must be cost effective. * It must be secure and not tumble down on top of someone if it is mounted on a wall. Brief 1 Idea 1 I want a car alarm to sound three times before the L.E.D's come on. Simple Sound Bomb Circuit How the circuit works! Once triggered the buzzer will sound for a set amount of time, depending on the size of the capacitor and resistor used. The time high can be worked out using the following formula-: 1.1 x R1 x C1 seconds. Advantages The alarm will come on when triggered Disadvantages The alarm will remain on constantly untill it is switched off. Idea 2 How the circuit works! Once triggered the buzzer will sound on and of, the frequency depending on the size of the capacitor and resistor used. The frequency be worked out using the following formula-: FREQ (Hz) =1.44 (R1 + 2R2)C Advantages The buzzer sounds on and off Disadvantages The buzzer will keep sounding untill the circuit is switched off. Solution How the circuit works! Once triggered the relay will activate for a set amount of time, depending on the size of the capacitor and resistor used in the monostable circuit. ...read more.

Conclusion

I think the best material for my housing would be MDF as it is easily painted to whatever colour I want it, it is easily cut to the size I require, it can be glued or screwed together, it is cheap and it is quite durable which may be important if the display is in a showroom and gets load of use. Now I know what material I am going to use I must now decide on what type of box to use. There are many type of displays I could use. After many scrap pages I have decided on these next 3 shapes. There are many advantages to each of these shapes. Shape Advantage Disadvantage 1 It is open and easy to see what's happening The L.E.D's may not stand out well as there may be to much light 2 With this box your sight is focused in the middle because of the two sides and the sides will restrict light so the L.E.D's will stand out more. You have to be looking straight at it. 3 With this box your sight is focused in the middle because of the two sides and the sides will restrict light so the L.E.D's will stand out more. This box could be two enclosed with not enough light. Using this table I have decided to use shape two. Below is a diagram of what I hope the finished product to look like. Conor Mc Collum 4 Lisb 1 ...read more.
