We first had a penny board that I brought in from home.
Since we had to attach something to the motor that will turn it, we took everything that might work. We found wheels in Ms Chan’s lego box, glue caps from home and many more.


After tests, we decided the glue cap was the best object that would suit our needs. In our first design, we originally decided we will put it at the front. However, after seeing how the motor will go on, it was evident that the motor would not fit on the front wheels unlike what we anticipated on our first and the second plan as you can see below.

We attached it at the back wheel as you can see in the bird eye view photo and in the close up.

However, since the motor could not become stable, we had to use cardboard to lift the motor up that can make the glue stick touch the wheel like the above.

After we attached the motor that produced light, we decided to increase the safety a level higher by attaching a device that can produce sound when the rider wished. In order to achieve this, I decided to use an NXT system. This is how our third plan came into
We attached an NXT Brain connected to an ultra-sonic sensor below the skateboard. I programmed it so that when an object came into a certain distance within the sensor, a sound would come out from the brain. The picture of the 3rd and final plan is below along with the side view of the Penny Board.
