* rejoice *

since last night i feel much better. this is the reason why.

i thank god for 2 things.
1) telling david early on in the design stages to think of another idea and try to covert air power into mechanical power. after reviewing that cart i decided that it will be a backup plan only to realise 2 nights ago that it is a very wise choice.
2) Yin Leng for telling me to try using the backup plan and improve it.

basically david's idea was really good. he did most of the design and i remembered that i suggested him to move the valve from facing the tophalf of the gear to facing the bottomhalf of the gear, which was a good move indeed as even my lecturer, Dr. Colin Burvill, commented so. Jon Hua who i thought contributed little thought of a very good startup of the car and it was effective.

on flat surface we did 8m at least. today the track was on a bumpy tiled floor and the most we did was 2.71m [our requirement was 10m]. we wanted to use 6 balloons but apparently we wasted 3 mins just getting the car ready. so we had to use 4 and it wasn't too shabby. it's a shame though that the lecturers could not see the real performance of the car, but what matters was that the car moved!

the official fastest time for 10m was a 2 wheel shaft-cum-car of 3.47s. however after everyone left this dart-like car made like 2.68s in 10m!!! that's amazing! it's a shame that the lecturers weren't there to see it!

all in all i felt really good. i've learnt a valuable lesson from this whole project and i pray hard that i do not repeat this mistake in the future.

i shall post up the car's pic in the near future if possible.
