Here is some advice on how to make a great impression:
1- Make sure your project is always "Demoable"
- At any stage in the development, you should be able to make a demonstration to someone walking by. If you feel you have nothing to show, then you are probably not heading in the right direction.
- Instead of working one feature at a time, work on all features progressively.
- Always keep in mind the vision of the finished project and make sure everything you work on builds up towards that vision.
- Think about the Demo itself. The project probably makes sense to you, but someone who has never seen it might need a didactic interaction in order to "get it".
2- Find a way to make it interesting to a broad range of people
- You might be working on a very complicated problem from a computationally point of view, but this might not be very interesting to people outside the field.
- Find a way to relate your work to a broad range of disciplines. For example, if you are working on a portable Head-Up display, you can explain people how it could be used by an architect or a doctor.
- Try practicing ways to make your project sound cool. How would you describe it to a 10 year old kid. By the way, my team won the people's choice award by only a couple votes which were cast by a group of middle school children. (The runner up project was iLights, check it out)
3- Take pictures and make videos !
- Keep a record of all you have accomplished-- you never know when things are going to blow up.
4- Advertise your key differentiators
- Think about every aspect of your prototype that could be a competitive advantage.
- Is your project a revealing innovation?
- Is your project 10x cheaper than similar products in the market today?
- Is your product faster, smaller, cooler ?
- Is your product fool proof ?
- Is your product RoHS compliant ?
- Is your product children safe?
5- Sharpen up your Marketing and Public Relations skills
- Spend a good amount of time making an appealing (but also functional) poster.
- Make video demos that people can watch online.
- Call a local newspaper or magazine and tell them about your work.
- Talk to the department's editor so you can get on the school's website.
- Go to national and international competitions.
