As we started working on our prototype, we made sure to track our weekly progress and stay on top of everything we needed to complete.

The team worked on the 3D model of the bottom portion of the bottle which will hold the electronics. It was previously printed during the mock-up phase and needed to be fixed.

The team started cutting out strips from the roll of sheet metal. They cut strips ½ inch wide and the length of the roll. They used clamps, a sliding cutter, ruler, and scoring mats to do this. They cut 8 strips in this fashion. Once the strips were cut, they used the mallet to smooth them out

The team used the mallet and the small screwdriver to puncture a hole at the top of each strip, about ¼ inch from the top.
The team took black and white wire and cut them to the length of the metal strips. They cut 4 black and 4 white wires. They used scissors to cut the wire.
The team used wire cutters to strip the end of both wires. Then, they wrapped one end of the wire through the hole in the metal strip.
The team used the soldering iron kit to solder the wire to the metal strip. They used gloves for safety and did it on top of a scoring mat to keep the metal from getting on the table.
The team used the voltage box and a motor with frayed ends to make sure that the metal strips and wires were properly connected. They did this by running a current through the strip to the motor and seeing if it started to run.

The team started working on the code for the mobile app that would be paired with the water bottle.
The team used thin plastic and the heat gun to start laminating and sealing the two metal strips together. The actual prototype would use one strip with a black wire and one with a white wire, but the testing used separate strips. The team initially used clamps to try and hold the plastic in place but transitioned to using a ruler, which was more effective at separating the metal. They switched to a narrower fitting on the heat gun to better direct the heat and double-wrapped the plastic to make sure that it didn't rip.
The team filled a plastic bin with water to test the capacitor they had created. They connected the wires to the Arduino chip, which was connected to the computer, and incrementally submerged the capacitor in water to see if the computer was able to get specific readings on the water level.

The team printed out a revised version of the bottle with holes for the wire.
The team used the laminator in the front office to accurately seal two metal strips together
The laminator went all the way up past the wires, so the team had to cut the top piece of lamination off. They used the heat gun to reseal the edges and ran a test to make sure it worked.
The team printed another revised version of the bottom section of the bottle. They took out the supports made by the 3D printer and glued the magnets and batteries in.

We started testing our capacitors to see if they are accurately recording the water levels. We used the beakers and connected the capacitor to the program on the computer.

We started updating the website in preparation for our critical design review from peers. We also started adding in the new elements that we have been recently working on.

We continued doing calculations within our testing. Specifically, we were looking for a relationship between the water level and capacitance to understand the readings we were getting.

We worked on a critical design review and added Elements E and F to our website. We presented Elements E - I to the class. Our peers gave us feedback that we can use in order to modify our project. We also gave feedback to other groups.

We are finishing our test procedure so we can record our data when we are testing. We are starting to test our temperature sensors as well as our LED lights and resistors.

We were on spring break, but the team continued to work on testing and the from home.
March 27 - March 31
March 27 - March 31
The group started the UV testing in Mr. Henning's room. We collected water samples and put them on plates to incubate. We have three separate testing groups.
