Team fidget spinner By: Matthew Flicker, Kevin Puliti, and William Pinkow

Problem

Who - Shawn Rowe, a young male who attends Garnet Valley High School who also has ADHD, which means he has a hard time focusing. He is often very loud and makes a scene when in public.

What - Shawn has a hyperactive disorder known as ADHD. It is hard for him to focus in school and on other things.

When - Everyday when he tries to study or attempt to do his homework. Shawn can’t concentrate when trying to do this.

Where - At school and when he goes out in public.

Why - He takes medications to help calm him down, if he gets too hyper. This calms him down by working in reverse effect. We feel that if we can make the spinner for Shawn, then it will replace the medications and therefore if he is getting too hyper, then he spins the spinner and calms down.

In the United States of America, the number of young people with ADHD continues to trend upwards. According to the Center for Disease Control, better known as the CDC, approximately 11% of people between the age of four and seventeen have attention deficit hyperactivity disorder. One of these kids is Shawn Rowe. Shawn is a young, energetic student at Garnet Valley High School. Since he has ADHD, he has a difficult time on focusing. In order to reduce the effects of the hyperactivity disorder, he must take medicine every day. Without medicine, staying on task is difficult for anyone with ADHD, especially in school. The problem is, the medicines are not flawless. While the safety of drugs used to treat ADHD is not known for sure, there are some potential risks and red flags. Since medicines for the disorder are stimulants, it is possible for the user to develop an addiction to the medicine. It could also potentially stunt or slow growth in the user, and the medicine is sometimes shared with other people who do not have ADHD. In order to reduce the amount of medicine Shawn has to take, a spinner device will be created for Shawn to have in order to help him pay attention so he does not have to use as much medicine. According to a new study published in The Journal of Abnormal Child Psychology, researchers found that when students with ADHD were asked to perform a task that involved working memory and organization, those who were allowed to move or fidget did significantly better than those who were asked to keep still. If he starts to lose focus, he can begin to use the spinner and stay on task.

Brainstorming

We drew a few quick ideas that we had for our spinner.

Research

We put all of our research into a coggle page which makes it easy to follow along as we gained more knowledge.

Build

First, we wanted to see what the spinner would look like before we printed it. So, we made a 3D model with all of the weights and bearing to make sure we liked it before printing.

3D Model of What It Would Look Like

Moving on to Printing

We then changed our STL file to a Maker Bot file and plugged it into the printer to begin printing.

Printer We Used to Print Our Spinner

Printed Model

After our spinner was printed we added the 608zz bearing and all the weights which were 3/16, 3/8, and 9/16 ball bearings.

Spinner with Weights After Being Printed

Test

To test our spinner we put it onto a skateboard truck screwed to a board with a 3D printed part and a nut holding it in place. We then lifted the arm until the back of it was flush with the wood and droped it on the edge of the spinner. We started the timer as soon as it started and when it completely stopped. We recorded the time of each of the three heights three times each.

Our Times

Analyze

Relationship Between Weight & Time

We found that there is a relationship between the weight of the spinner and the amount of time it spins. This relationship is limited because, if there is too much weight, then the arm can't make the spinner start fast enough. However, if there is not enough weight on the spinner, then the spinner will not be able to keep spinning for extended periods of time.

Relationship Between Number of Arms & Time

The number of spokes can have little or no effect on how long a spinner can spin. Rather, it is what is on the arms that makes the difference. If you were to give the spinner 20 arms, all of which with no weight on it, the spinner would not last for very long. However, if you were to make a spinner with 3 arms and .8 grams worth of weight on the arms in total and the weight is evenly distributed, then the spinner will last much longer. The number of arms of the spinner is much less important than the weight and balance of the spinner in general.

Relationship Between Height of Trial & Time

In theory there is a correlation between height of the trial and the amount of time the spinner will spin. Since, gravity is working longer on the arm so there would be more force. However, that is not what we found during the testing process. We found that the way our design caught the arm caused Tier 2, the middle tier, to have the most consistently long spin times, which lasted on average 3 minutes and 25 seconds on each spin. Tier 2 also had the longest spin, at 3 minutes and 40 seconds.
