Let me know if this is of any help.

I replied asking for information on their newest models and specifications and anything else relevant.
I also carried out a small survey of 20 of my classmates to find out what they thought would be the most effective way to advertise this product. The results are as shown.
As you can see clearly from the table and graph the overall majority think that the most effective way of advertising would be using Light and Sound. I will try to use both of these methods in my final project.
The task is to design a dynamic advert for displaying a company’s wares in a showroom/office etc. Design and make an advert, which includes electronics.
I have 40 hours to complete this task and I should aim to spend 13 hours on the designing and 27 hours on making the final project. I need to spend more hours on making the electronics rather than the case, as it is these that I get the most marks for.
Things I need to find out!
- How many different ways are there for making an advertisement like this.
- My random flashing lights will need a pulse generator; how many ways can this be made and which is the easiest and most cost effective.
- Is it possible to get an alarm of some kind that sounds like a car alarm to run on a 9v battery?
Safety
Is my project safe is their anything that could hurt people.
Size
I plan to use a model car so I need to design the size of my box around the size of my car.
Shape
I need to ensure my car will fit in the shape of the box and it is well proportioned.
Colour and Finish
My advert needs to be attractive to look at some times bright colours are too hard to look at. Also if it is a light colour my L.E.D’s will not stand out.
Material
I will need to consider what material is the cheapest and if I will be able to make it into the shape of my project.
Durability
My advert will need to last and hopefully will not break easily.
There are many specifications my project needs to achieve.
- The project must be completed by early April 2004.
- The project must take no longer than 40 hours.
- The project must include electronics in a suitable case.
- 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. The time high can be worked out using the following formula-: 1.1 x R1 x C1 seconds. Once the relay is triggered the buzzer will sound on and of because of the astable circuit. 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
This circuit fullfills all my requirements so I will use it in my finished product.
Brief 2
Idea 1
To activate a series of flashing lights. Firstly for the lights at the rear of my circuit to start flashing and after a set amount of time the lights around the car to start flashing.
How the Circuit Works
The lights will flash on and off. This is set by the 555 chip. The frequency can be determined by The 2 resistors and capacitor set the frequency.
FREQ (Hz) =1.44
(R1 + 2R2)C
Advantages
The lights flash on and off
Disadvantages
All the lights will flash at once not in sequence like I want them to.
Idea 2
How this circuit works!
Pulses are supplied from the 555 astable circuit to the 4017. As the pulse from pin 3 constantly changes the 4017 output. The output from the 4017 will rotate around legs 2,4,7,10,1,5,6,9,11. Causing the L.E.D’s to appear to be chasing each other. The frequency again can be determined by the same formula.
Advantages
The L.E.D’s will flash on and off in a random fashion.
Disadvantages
The circuit will stay on until it is switched off. I want it to stay on for a set amount of time.
Sollution
How the Circuit Works
This circuit works the same way as the previous circuit apart from the time delay. When the push to make switch is pressed it activates the 555 timer, which remains on for a set amount of time set by the resistor and capacitor. The formula for time high is.
1.1 * VR1 * C1
Advantages
The L.E.D’s flash on and off in a random fashion for a set amount of time
Disadvantages
There is no disadvantages to this circuit this satisfies all my requirements.
This circuit could be used twice for the lights at the back of my project and the lights around the car.
How the Circuit Works
When the circuit is triggered it sets off the two 555 chips both of them are timers and the circuit is powered up for a set amount of time. On the first part a buzzer will sound three times. The second part of the circuit will switch on 10 L.E.D’s which will flash on and off in a random fashion. The third part will wait for a set amount of time set by the resistor and capacitor time delay. After the time has elapsed the lights will begin to flash on and off.
This circuit fulfills all my requirements so I will use it in my project.
There are many types of materials that are accessible to me as a 5th year Technology student, from acrylic, MDF, solid wood and metal. In this chapter I will investigate the properties of these materials and decide what would be best for my project.
These are just a few properties I could use for my project. 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.
Using this table I have decided to use shape two. Below is a diagram of what I hope the finished product to look like.
