Hey guys! I know most of you guys are on spring break, so this will be a short post about my week. Since I took off a few weeks ago, I still needed to go into ASU to get my 15 hours. And let me tell you, the ASU campus during spring break is dead. By observation, it seemed the only people on campus were the graduate students. As my sister put it, "There are no breaks in a life of a graduate student, including mine."
Not much happened this week in terms of my new project. The group I'm working with is slowly getting everything together so we can finish making this pressure sensor. The only thing I did this week was research the wires the lab and I are going to use for the circuit board. Why you ask? Because I need to know the spacing between each wire. Why do I need to know the spacing between each wire? Don't I just get 12 wires and create a circuit board? No. Before I would have though that, but in reality the wires come in a long strip. And each long strip has a bunch of wires. Since the lab is using a flexible wire type, I need to research online the spacing to edit my circuit board design. In my last blog, I put a picture of my circuit board design. So if you haven't seen it, you should go check it out. On my design, there is a total of 12 lines in that photo, and therefore 12 wires for the circuit board. It was important for me to know what the spacing between each of those wires needed to be, to ensure there was enough space on the board, and that the wires wouldn't touch. From researching online, the spacing between each of the lines needed to be 0.1 inch apart. Knowing that, the lab can put in an order online (or go buy it in a store if it is available) to speed up the production line.
So that's about all that happened this week. Not much hands on experience, but hopefully in the next coming weeks, the project will be complete and we can start different testing with the pressure sensor. Hope you guys are enjoying your spring break! Until next time!

Hi Tina! What does the spacing between the wires affect?
ReplyDeleteWhy I worried about the spacing was because each square of 6x6 matrix of the pressure sensor is only 3/4 of an inch, so I needed the precise spacing of what the wires will come as to then see if the design worked
DeleteTina: YOu are living the most common situation of SRPs....the one you finally are doing is not remotely like the one you thought you would be doing when you began the process. However, your project looks interesting and I am encouraged that you will be able to bring this project to a conclusion by the time you have to do your final presentation. The pictures you provided are very helpful in understanding your new and improved project. Keep doing what you've been doing.
