6/5/07 New Wheels

I bought some new wheels today. I changed the wheels because tests after tests, the CD wheels can are just not working right. So I got 4 foam wheels to replace those.

5/20/07 Final Assembly & Quite A Few Adjustments

Later on in the day, I started putting all the materials together. It did not turn out perfectly as planned. As my father and I worked with the rubber band and the 1 kilogram for weight, we had to make many changes. Some more CDs had to added for wheels, and place adjusments for the rubber band. We still have to do a lot more things to do before it is finished. I will keep you updated.

5/14/07 Materials & Blueprint (Paint Program)

Today, I bought the materials I needed to start making my rubber band car. The other picture is the blueprint with the 3 differents views of the car (Top, Side, & Front). No need to explain anymore.

5/7/07 Blueprints (Paint Program)

I went over, with my dad, the different ways we could propel the rubberband car. On the rough sketch blueprint, the peg will hold the rubberband in place. The rubberband is wrapped tightly around the wheel axel. When the car is released, the rubberband will want to pull back towards the peg which will spin the axel causing the car to move.

4/30/07 Ideas and Not A Single Rubber Band

My father and I talked about what to do about the rubber band car project. We talked about the main issues such as the frame, aerodynamics, wheels, and the capacity to hold one kilogram (2.2 pounds). We thought of a possible way for the wheels to spin smoothly as if they had bearings in it. Our only major problem is what to make the wheels out of. I do not want use the materials the old classes used or those seen on the internet for the wheels. I am going for creativity here.

4/24/07 Just Thoughts, No Rubber Bands

Today we were introduced to the Mass Transport Vehicle project in Mr. Tillay's class. It was a very straight forward presentation with a few advices here and there. As a class, we were able to go on the computers and check out the site set up for this project (http://dhsvhs.org/tillayd/dc/index.htm). I went on thinking about the rules (especially where it says that we may not use the rubber band as a slingshot) and I asked if it was okay to cut the rubber band. It was okay to do that and so it gave two options for my project now. The subject about Mr. Gillespie's wind tunnel came about and so I will consider it. The thought on my mind now is whether the car will be a front-wheel drive or rear-wheel drive (i.e. Which is easier, to push or pull a heavy object?). I will just have to try it out when I get home from school.
