Final Presentation and Last Day

Today was sadly the last day of our internship. We presented our final presentation to an audience of what looked like about thirty to forty people. I was a bit more nervous than yesterday but it still went very well. After, we all received a certificate of recognition and a letter of recommendation. It was so great to have this opportunity to participate in this internship and meet so many talented, extremely intelligent, and creative people. Even though it probably took about four weeks and a few group bonding activities to become comfortable with everyone, I was able to get to know everyone and all their unique personalities very well. The best part about this internship was the environment - as everyone was so knowledgeable about their project, and actually excited to learn and teach others. I really hope this internship continues and grows because it is one of the best summer experiences I've ever had. Thank you so much for accepting me, this was definitely an experience of a lifetime.

Rehearsing Our Presentation

On Thursday, we all rehearsed our presentations in the large auditorium! It was extremely nerve-racking when I was about to go up to the podium to present, but when I got up there I actually felt relatively confident and excited to tell the story of our project. Nate and I took into consideration the constructive criticism the other interns and Joe and Bob gave us. After, we ate our last lunch as a group where all twelve of us played a game of "President." Then we went back to the lab to work on our presentation and we were able to correct it to perfection!

Finalizing

Today we finished our presentation and we are ready to present tomorrow! Our difficulty today was trying to embed our videos into our power point because we can not use YouTube or the internet in our power point. We tried putting the videos on a USB drive at first so we would simply play the videos after our presentation, but when we tired that, the format of the videos made it so that the videos would freak out when played. Then we asked around to see if anyone could get the video onto the slide, so we used Reagan's computer which has power point initially, then Trevor helped embed the video! After, we gave the presentation over on a USB drive and we will do a run through of our presentation tomorrow!

Perfecting our Presentation!

On Tuesday, Nate and I wanted to get the system working again to see if we could do our tests, so we walked over to the machine shop and had a hole drilled. When we came back, the new light fit perfectly in the new hole, but the image was not very clear and the image was also brighter on one side. We even put a pin hole in front of the light to make the image be more focused, but it didn't work. After lunch, we presented to Aly, but we forgot to time it and that was the initial reason why we wanted to present! She really enjoyed the presentation and gave us minimal things to fix!

Getting the Presentation Ready!

Yesterday we worked on our presentation for almost the entire day. We also talked to Bob and Joe about our broken light so they brought us a pinhole and a really bright light! Then we talked to Aly and agreed to run through our presentation for her the following day to time it and tweak it for this Friday.

Broken Light

On Friday, Nate and I tried to Solder our light back together. Yiquin brought us a switch to see if that was our problem, but it still did not work even after changing the switch. We tried using a spare light, but it's not as clear as the previous light. Afterwards, we went outside to have our last cookout where we played volleyball and ultimate Frisbee. Then I had to leave early to walk across campus to participate in RIT's college and careers program!

Presentation Work

Today, Nate and I worked on our presentation in the morning. We wrote our outline on the white board and sorted our who will explain which aspects of our presentation. After, we went to lunch with the other interns. When we came back, we visited Yiquin and Kevin's lab to see how they are progressing with their camera. When we came back to our lab, I found another type of glue for our foam and hopefully this one will finally stick!

Spray Adhesive!

Yesterday, Nate and I went outside with the Schlieren System and the carrying case to glue the pieces together. Then we came back in to let it sit overnight. We also looked at really cool posters that showed some research done during the summer. After, we went to lunch and came back to watch a presentation about life on mars. This was a really interesting topic and the speaker also kept me intrigued with her deep interest in the topic!

Slow Tuesday

On Tuesday, Nate and I worked on our final presentation. We then ate lunch with the other interns and afterwards, I had to leave. It was a very slow day, but at least we are getting prepared for next Friday! We also spoke with Ally and she gave us some adhesive spray glue to glue the foam together!

Busy Monday

On Monday, Nate and I worked on our case for the Schlieren System. We were able to go to the machine shop and get our Plexiglas cut to protect the mirror while it's in the case. After, we ate lunch with the other interns at global village. Later, we did the grey scale tests. This was taking pictures with different exposure levels at different points on the knife edge to see which point would give us the most contrast (clearest image). This time we took two pictures at each point, made data points, and then graphed them on excel.

Graphing and Data

Today, Nate and I first cut the piece of Plexiglas at the machine shop that would be used to protect the mirror. After, we talked to Gary and did our grey value testing. We tested different amounts of light the knife edge covered - each with multiple exposures. We compiled all our data onto spreadsheets and made graphs for each point. We plan on emailing our results to Gary and Aly and see if we should retake some images.

Bring Your Friend to Work Day

Today was bring your friend to work day, so I invited my friend Katie. It was so much fun showing her all the labs and the campus, and I think she's beginning to like science more! We ate lunch outside again like we do every Friday, and we worked on some more designs afterwards.

Bike Trip!

This morning, Nate and I glued together the foam pieces and looked at ways to solve the super saturation of  the images we took for our test. After, everyone went on a bike ride to Mt Hope cemetery and a sub shop. This was my first time on a bike in many years so it was definitely challenging, but a lot of fun! After, I cleaned up the place for bring-your-friend-to-work day, which is tomorrow!

Foam!

Today, Nate and I drew some more designs for our metal and Plexiglas box. Then we had pizza for lunch and listened to an interesting talk about wild fires. After, we thought about more ideas when Bob and Joe came in with a giant box of foam and a container for our system! (Thank You!) We then cut the foam and put all the parts inside. Our next step is to finish up the gray scale test and fix our essay and final presentation.

Overcoming a Hurdle

On Tuesday, Nate and I worked on different ideas further and designed both on inventor. One incorporates a suitcase, while the other one uses a plastic box with wheels and a handle. We showed both ideas to Gary and he liked them, but the next issue was the price. The box and the suitcase are around the same price ($35), but the foam that is placed in the inside is around $50. Gary told us we should get the price down to around $60, but it is almost impossible if we need both foam and a box. To accomplish this hurdle, Nate and I are thinking about building our own box out of the materials we were given, which includes screws, metal bars, and any scrap materials we can find. It's difficult trying to build a box that is lightweight, sturdy, and has wheels. We will try to brainstorm more ideas on Wednesday. Nate, Trevor, and I also visited Yiquin and Kevin's lab, and their 3D camera is coming together pretty well! It is so cool how they built a working 3D camera out of tiny computers, also known as Raspberry Pis, batteries, and two lenses!

Correcting and Fixing

Today Nate and I read the constructive criticism Aly and Gary wrote on our essay. We spent a lot of time correcting errors and adding details to our essay. We also searched for containers to package the system into. Then we designed an insert for one of the containers on inventor. Tomorrow we will show Gary and Aly our work and hopefully we can purchase a container soon!

Presenting

On Friday, Nate and I finalized our essay and presentation to show Aly and Gary. Then we ate lunch outside and played volley ball with the other interns. After, we presented to the graduate students and they gave us constructive criticism and new projects to complete. We were given new materials and supplies to build an iPhone holder and perform an experiment that measures contrast in the images we took.

Thursday

Today, Nate and I worked discussed ideas for packing the Schlieren System to make it portable. We looked at some boxes and we figured out that we need to work on our design more. We also started a power point to show Aly and Gary tomorrow. We also showed Tommy our lab and experiments. Later, I went to Jason and John's lab to try the eye tracking glasses. They didn't work on me so I went back to the lab and finished working on our final paper.

Wednesday

On Wednesday, I worked on finding a box for the system and though of other designs. For lunch we went to this really interesting lecture about remote sensing and ate pizza. After, I went to Javas and had a raspberry lemonade drink.

Tuesday

On Tuesday, I worked out in the gym in the morning. When I came to the lab, we wrote more of our final essay and worked on our presentation. After, we took a field trip to the observatory which was amazing! The sky only got completely dark about 30 minutes before we left, but we saw a satellite and the milky way. It was also cool to get to know everyone a bit more!

Monday

On Monday, I showed Nate what I had worked on during the past few days. We talked about other ideas and we finished building the color filter wheel.

Relaxing, but Productive Day

Today was a very relaxing day, but very productive. In the morning, we peer reviewed our abstracts. The other interns and instructors agreed that Nate and I should combine our abstracts into one, because there were some parts missing from mine that were in his, and vise versa. After, I came to our lab and I set up the Schlieren system with all the parts and it worked perfectly. As a bonus, it was extremely easy to set up! I then decided to try to make a prototype for the color wheel idea, which uses color filters to enhance the image. I showed the prototype to Aly and she thought it was really cool! I then glued some parts together and drew some diagrams of possible ideas. Lunch was also very fun playing volley ball and eating as a group. It was hilarious how the picnic table almost tipped over! When Nate gets back, I think we will get the pieces for the phone holder and write more of our final essay. (Pictured is the color wheel prototype attached to the working Schlieren System)

Trial and Success!

Today was another busy day! This morning I tried to get the hinge idea to work, so I built a 3D model on inventor. Inventor actually liked me today, which is unusual, and the hinge I built on the computer moved like an actual hinge! Then I did a bunch of calculations to see if the idea would work, and it did for the most part except the hinge would still not close properly. Then we went to Global Village for lunch. After I came back, I showed Gary and Aly the idea, and they thought it was really good! After talking it over with them, I had a Eureka moment and I moved the pieces around, and doing so, it solved all of our problems! We got rid of the hinge completely and interconnected the pieces. Coincidentally, the alignment was just perfect so we didn't even have to make any more cuts to the length. I just had to move around the pieces under the mirror, and this is when I discovered making the Schlieren System is a two person job, because it is extremely difficult to hold the 20 pound mirror upside down while trying to screw bolts into the frame with only two hands. After I got the pieces adjusted, I went to the machine shop and got holes made by the same college student who cut our parts yesterday. All we need are some longer screws and the portable Schlieren System will be complete! (Pictured tis the hinge I built on inventor next the the actual hinge).

Abstract- 7/16

      The Schlieren Imaging System allows one to capture the different substances in air that light passes through: even if not visible to the human eye. Our objective is to build a more portable Schlieren System, which will enable the device to be transported more easily to show others how cool optics really is. We were also tasked to make the system “cooler” so we are planning on creating an add on piece that will allow viewers to place their phone inside and record the image.

Trial and Error

Today was an extremely busy day. In the morning, I drew an idea Nate and I created to incorporate a hinge into our setup. I used the white board, made calculations and measurements and then showed it to Gary. He liked the idea so I made measurements on a rod we were given for it to be cut. Then we had pizza for lunch and looked at some cool college projects. After, Gary and I went to the machine shop to have the parts cut and made. A really nice college student helped us cut the pieces and she did an excellent job! I came back to our lab and discovered that the hinge was very wobbly, which was really, really bad. Gary thought of just sticking to the hinge and creating another prototype that doesn't use a hinge, but I want to see if we can still use the cut pieces and create something that doesn't use a hinge and won't be wobbly. After Gary left, I decided to draw the cut piece on inventor. Tomorrow, I will try to build another piece that we will add on using inventor that will hopefully solve our problem. (Pictured is a mechanical engineering student learning how to change the blade on a ban saw, if you look closely, you can see the sparks created from the blade).

Day 7

Today we wrote our abstract for the Schlieren System. We also attended a college students defense about satellites and taking pictures of the earth.

Building A New Setup

Today, we brainstormed some more designs and actually built one of them! We made it more portable by using less bars and we also removed the bulky legs. After getting it checked out, Nate and I plan to cut some of the pieces and complete our design. Later we made some better demos using our new setup.

Day 5

On Friday, Nate and I worked on Inventor for the majority of the day bringing to life one of our designs. This took about 3 hours to put together but it turned out great! We went outside for lunch and had a cook out which was really fun. We played volleyball against the college students, and afterwards, we presented our progress to Aly and Gary. They gave us constructive criticism that we took into account.

Testing

We worked on some more ideas for making the Schlieren System more portable. We also did test to see if we could obtain a clearer image by moving the "knife edge" around. We found that when it covers about 50% of the light reflected onto it, the image is the clearest. Nate and I also tried other filters and showed our machine to some of the other interns who thought it was pretty cool! (This is an image of our set up at the moment)

Brain Storming

Today we brainstormed more ideas and drew a few of them. The one we drew came out to using the exact same materials so we were challenged to think of other ways that would not use the heavy rails the system is set up on. We thought of a tripod idea, but it may be too simple.

Building the Schlieren System

Yesterday, We did some fun team building activities in the morning. Nate and I built the Schlieren System. It did not take long to set it up but we could see that it was not very portable. We started brainstorming ideas to enable us to bring the system to other places easily. Some of these ideas included cutting the bars that make the system in thirds and putting hinges on the rails so we can carry it easier. We also tried some demos using fire, ice and our hands. We are very ahead of schedule!

Day One: Research

Today we toured the RIT Imaging Science building and learned what projects are being created here. Nate and I started researching our project which is to build a portable Schlieren Imaging System and we were also introduced to Aly and Gary who are graduate students!
