Prototype Testing

One of the problems we have come across in the early stages of coming up with a prototype is deciding how long we should make the stadiometer bar. In order to help us make a decision I have created an adjustable bar that we can use to test length. I was able to use my knowledge in solidworks and training in the maker lab to have an acrylic base to the bar laser cut. I think this early test will give us a good idea of the size of our product. Besides the length of the bar we also wanted to put in perspective how wide the bar will be and if it will be feasible for what Niki needs.

As you can see in the image above I have drilled holes to make the length of the bar adjustable between about 10-16 inches. I have made the bar wide enough to fit the ultrasonic sensors and the arduino mega. The big holes on each side are for the ultrasonic sensors and I also had four small holes cut (which are hard to see) that i think should fit the arduino mega. These holes are not in the place we want them, mainly because the adjustable holes take up most the bar. I put these holes in order to make sure they would work for the arduino since they are very small and precisely located.
