The goal of this week
This was the first week of our project therefore, the goal was to meet the lab group, get familiar with the topic, understand the expectations from us and set the path for the project's progress.
What have we accomplished?
After meeting up with the lab we started on our literature research, which was pursued for the next 4 days. While doing literature research we also started working on the website, we set the design, added an introduction to our project on Home Page, and added the information we obtained from the paper in the Background section. We created the Gantt Chart for our project and added it to the website. We started preparing design ideas and presented them to the lab group. After the discussion with the team, we finalized the general setup and the materials we needed to obtain.
What is the plan for next week?
Next week, we will try to order the rest of the materials still needed. We will start building the setup with the materials we have obtained this week.
Monday, February 6
This was the first day of our project, we had a meeting in the morning with our supervisor Gisella Vetere and PhD students responsible for our project. In the meeting, we learned more about what is expected from the design and what our focus should be. They provided us with a tour of the lab to show what they have already done regarding the topic. After the meeting, we received the essential relevant papers and with that, we started our literature research. We came up with a basic design based on the papers that we received from the lab. Moreover, we started setting up the website by watching tutorials together and getting familiar with the system. We discussed how the design would look and decided on the overall organization. We set up Gantt Chart, assigned the first roles, and added them to the website.
Tuesday, February 7
We decided to work remotely through online meetings due to the strike. We continued our literature research. Based on the literature research conducted, we prepared four design ideas and we decided to present these ideas to our supervisors in the lab. We dug deeper into the specifications of the design and the materials needed. Later on, we prepared a general overview of what is essential and what is suggested in the final design. Additionally, we continued setting up the website by organizing the visual interface.
Wednesday, February 8
We met up in OpenLab to continue our project. Our first task was to generate a list of materials that we would require to construct the olfactometer. We also added information on the home page and the background page of our Tikki. We wrote down the specification of our project and prepared a mini-presentation for the lab meeting that we have on Thursday, February 9th. We finished the Gantt chart. We created a Setup for our projects with different units.
Thursday, February 9
We prepared a presentation to the lab group regarding the general overview of our setup, the design ideas we have, and the materials we want to use. We received feedback on these ideas we have. During the meeting, it was decided that we would like to focus on making the design low-cost, easy-to-build, and portable yet; as accurate as possible with the budget we have. For that reason, out of our 4 design ideas we decided to choose the ones that do not contain a manifold; due to customization issues and choose the ones containing a flowmeter for improving accuracy. Until our next meeting, we will prepare a document with the materials and their costs. We will also do more research on the specifications of the design. Lastly, we obtained Arduino UNO from the lab in ESPCI.
Friday, February 10
We decided to work in OpenLab to obtain some materials for the setup. We got most of the materials needed from the OpenLab; solenoid valves, Teflon tube samples to figure out the size we need, glass vials, and the equipment for Arduino. We shared the papers we found with our lab group and created an account for them on the website so that they can access the content. Furthermore, we finalized the cost and materials Excel sheet and created an inventory to know exactly where each material was borrowed. We researched the missing materials to be able to order them as soon as possible.
The goal of this week
This week the main goal was to finalize the materials list and start ordering them, start the Arduino part of the project and think of the final design arrangement.
What have we accomplished?
We have ordered the materials. We constructed the electronic part of the overall design which allowed us to open and close the solenoid valves. We implemented a vacuum pump to create a simpler prototype to symbolize the air tank. Afterwards, a pressure sensor along with a balloon connected to the pump was implemented to visualize the change in pressure using Arduino. We also started working on CAD drawings of the box/stand we want to use for arranging the materials.
What is the plan for next week?
We will finish the first draft of CAD drawings and try to 3D print them. Furthermore, we would like to have a simple working interface by the end of next week. Depending on when the materials are delivered, we might start working on building the setup. Finally, we will work on constructing our tiki wiki website from scratch.
Monday, February 13
We had a meeting with Gisella Vetere, Clement Pouget, and Maelle Chistaens about ordering the materials we still miss. We looked for the best materials possible and sent an email to receive quotes. We continued working on the About us and Drafting sections of the website.
Tuesday, February 14
We contacted all the distributors to order the products. We downloaded Arduino IDE and started working on combining the parts. We used a pressure sensor to see if we get outputs in Arduino IDE, and we did get them. This can tell us the pressure in kilopascal that is applied to the device. We received responses we sent to distributors for quotes so we responded to them and send the quotes to our lab group. We finished the Drafting section of the website.
Wednesday, February 15
Today, our tiki wiki was down due to an unfortunate change that was done in the customization code. We contacted our program coordinator to reach out for a solution. For that reason, we were not able to work on the tiki wiki. We started working on building the Arduino side of the prototype. We were able to open and close one solenoid valve twice, but after that, it was not possible. We think it might be due to a problem with the solenoid valve itself, or the power for the valve is not enough. To investigate the problem, we will try some modifications to see if they contribute to the issue. We will first test the system using a LED bulb instead of the solenoid valve and connect a battery directly to the relay.
Thursday, February 16
We implemented the vacuum pump in the system to make sure it works, we tested it by using a balloon. Then, we tried to solve the issue with the solenoid valves we were encountering the day before. We realized that we were giving air in the wrong direction, therefore after researching the working mechanism of the valves we realized what was wrong. After that, we connected all four solenoid valves to our design with the addition of two more relays. We were able to open and close all of them. We made the setup a bit more organized by arranging the location of the materials. Furthermore, we made an illustration of the setup and took videos of the working process. We also started thinking about how to arrange the 3D setup. We thought of designing 3D boxes for putting the ingredients together to arrange the space better.
Friday, February 17
We started working on implementing the interface for Arduino. We made rough drawings of the general setup idea. We decided to implement a board below the relays to have them more organized. Then, we prepared the experiment we would like to test which measures the pressure inside the balloon.
The goal of this week
By the end of this week, we would like to bring back our tiki wiki website, have a prototype for a visual interface and prepare the first draft of the 3D design.
What have we accomplished?
We started working on the tiki wiki starting from the beginning, we brought it back to how it was before it crashed, then we added new content on Drafting and started working on Bibliography, Arduino, and Protocol sections. Furthermore, we completed the 3D drawing of our design and started printing them piece by piece. By the end of the week, we were able to print two vial compartments with different sizes. In addition, we were able to finish the first draft of the user interface which involves the manual selection of odors and their duration along with automatization of the selection by adding an Excel file. Finally, we wanted to work on improving the visuals of our website so we prepared more photos and videos of our experimental setup and CAD design.
What is the plan for next week?
At the beginning of next week, we are planning on presenting our design and user interface to our lab team in ESPCI. Then we will be working on improving the organization of the electronics compartment by either using a soldering board or PCB board. Moreover, we will start printing the rest of the design and start placing the materials we have in the printed sections.
Monday, February 20
We made the first draft of the interface where the display window opens and the user can choose the odor and the timeframe for delivery. We started setting up the tiki wiki website from the beginning. We worked on finishing the CAD drawing of the relay board and the setup support.
Tuesday, February 21
We started the day by preparing our relay board for 3D printing. While it was being printed we worked on our tiki wiki website. Since we are working on it from scratch, we transferred everything we have from our Google Drive backup and started adding the missing parts. We completed the CAD drawing of the overall setup. We printed the second board as well and attached it to the first one.
Wednesday, February 22
We divided the work among the three of us; Aurore was working on the code for the interface, Ezgi was working on designing the prototype on CAD along with 3D printing, Adrien was working on tiki wiki while helping on the code and 3D printing. For the tiki wiki, we worked on the protocol page where we added some videos as a visual aid and fixed the design. For the Arduino display, there was an issue with a delay where all valves were opening at the same time at the start of the program, we worked on trying to understand the problem with that. We were considering adding an Excel implementation on the display so it would be more automatized, but we will first discuss the need for that with our lab team. For the CAD drawing, we modified the size of the stand involving the vial and the valves and changed the location of the valve. Finally, we 3D printed one compartment today.
Thursday, February 23
We started the day by thinking of how to arrange the electronics in the setup. We thought of making a separate section next to the vial compartment. This section would have Arduino and a soldering board with cables at the bottom. After discussing the design for that, we started the CAD drawing. We did some trials on soldering to improve our technique. Then we started 3D printing the second vial compartment. Furthermore, we improved our Protocol and Drafting pages. We ended the day by prepared an introductory video of our setup and shared with our peers.
Friday, February 24
In the morning, we implemented an option to add an excel file to the program. In the meantime, we printed the second compartment again because there was an issue with the size of the other one. We continued on completing ''Meet the team'' section on the tiki wiki. We added a compartment for Arduino and the soldering board in the CAD drawing so we finished the first draft of our 3D setup design. We took photos and videos, then added them to the tiki wiki. Finally, we 3D printed the logo of our project; the mouse with air.
The goal of this week
This week our plan was to continue working on the visual interface, order additional materials if needed, and print the remaining compartments in the design.
What have we accomplished?
In our meeting on Monday, we realized that the sound generated from the valves and the relays every time they open and close can be distracting for mice, therefore, we looked into silent solenoid valves, and relays. However, due to their high price, we decided to keep our own materials and make a soundproof box instead. We decided to make our code more organized after we encountered some problems implementing certain functions. In order to accomplish that, we created a GitHub account and arranged the code to create Model-View-Controller (MVC) model for separating the visual interface from the model.
What is the plan for next week?
Our plan for next week is to finish the MVC model for the visual interface, print the rest of the compartments, perform the soldering, and buy material for the soundproof box.
Monday, February 27
On Monday, we 3D printed the second vial compartment. In the meantime, we had our weekly meeting with the lab team. During the meeting, we showed the vial compartments that we printed along with the Arduino system. We discussed the fact that solenoid valves and the relays make a sound every time the valves are closing, which could cause an association in the mouse. That could cause a problem in the experiment, therefore we decided to work on preventing that sound from reaching the mouse. After the meeting, we did some research on flowmeters and silent solenoid valves, when we found the most suitable brands we contacted the distributors in France to receive quotes.
Tuesday, February 28
In the morning we spent some time thinking a bit more about the issue concerning the sound of the relay and valves. We looked into 3 possibilities; changing the valves and the relays to quieter ones, changing our current design and adding some acoustic foam to reduce the noise, and putting our current design into a soundproof box that we would make ourselves. After discussing different possibilities we chose the 3rd option. This is mainly due to cost reasons and the shipping delay to have the new component shipped. We then looked into the materials we would need to build the box. In the afternoon, Ezgi worked on the tiki wiki, while Adrien and Aurore worked on the Arduino code. There was an issue in making our current code work on Windows. We then did some research to make the digital LCD work to display the mode and duration. We also brainstormed about how to implement in the code the visual feedback and the stop button.
Wednesday, March 1
Today was focused on the code and tiki wiki website. Ezgi spent the morning writing the text for recent advancements in olfactometers. Adrien and Aurore continued working on the code for the visual interface. They tried to implement a stop button, display data from an Excel sheet, and a display box to show the incident happening. In the afternoon, the team worked on updating the website's design to improve its visual appeal and user-friendliness by adding some additional images in some sections. We also collaborated on new ideas to change the design to reduce the noise created by the relays and valves.
Thursday, March 2
Today we all decided to focus on Python code for the user interface. In the morning, we created a GitHub account for the project so that we would be able to work collaboratively on our code. Then, we spent some time learning more about GitHub and how to use it. In the afternoon, we focused on improving our code since it is currently not possible to click on any other buttons in the user interface when the experiment is going on. This means that it is not possible to stop the experiment. In order to fix this problem, we did some research on Tkinter Model-View-Controller (MVC) model which would allow us to separate the interface from the model itself. For the rest of the day, we worked on implementing the MVC model on our project.
Friday, March 3
On Friday we continued focusing on the user interface, we started the day by following the Tkinter tutorial. Then from the information gained, we started implementing the MVC template and continued our research. We also did some research on soundproof mats to present the options in our weekly meeting on Monday. Additionally, we learned that our materials were not ordered so we added extra non-return valves in the quote and sent them for reordering.
The goal of this week
The main goals of this week are ordering our materials, 3D printing all of our designs, soldering and advancing the visual interface.
What have we accomplished?
In order to achieve our goals, we took several steps. First, we ordered necessary materials through the lab and supplemented them by purchasing additional items from Leroy Merlin. Furthermore, we aimed to improve the visual interface of our project by deciding on the overall design we want to implement and began implementing the changes incrementally. As part of this effort, we began 3D printing the electronics box and also performed soldering of the pins.
What is the plan for next week?
Once we receive our materials, we plan to begin combining the tubes and connectors with the 3D-printed box that we have already created. Along with this, we are working towards completing the visual interface of our project. We have set a goal to make significant progress in this area as well. Furthermore, we aim to start working on the poster.
Monday, March 6
Today in the lab, we had our weekly meeting with our lab group where we ordered the necessary materials for our project. They agreed to reimburse us if we directly purchased some materials from Leroy Merlin. As a result, we planned to go there on Wednesday. Following the meeting, we focused on the interface organization and explored the flowmeter. We also requested a quote for the Aurora olfactometer, and an industrial olfactometer, and received one for the non-return valves. Additionally, we added new buttons to the interface.
Tuesday, March 7
Due to the ongoing strike, we were working from home today. One of the main tasks was implementing the interface connection with Arduino using a file upload. We also created a code organization chart to streamline our coding process. Additionally, we created a countdown and worked on the visual feedback for the valves, which will be important for our project's user interface. To keep the website up to date, we updated the Arduino page on the tiki wiki with our new code. Finally, we also created a diagram to help visualize how the final interface would look like.
Wednesday, March 8
We went to Leroy Merlin and purchased a soundproof mat, plastic box, and zip ties to help with creating a soundproof box to cover our design. Back in the lab, we continued working on our code and implemented the interface connection with Arduino using manual selection. Additionally, we were able to 3D print the top of the electric box, which will help with the overall organization of our project. As we continued to improve the user interface, we started working on adding a graph to the window that would display the added Excel file. This feature will help provide a better visual representation of our project's data, making it easier to observe which modes are running.
Thursday, March 9
Today in the morning we started 3D printing one wall of the box but due to the use of a different printer there were some issues in printing. That’s why we will be using another printer tomorrow. Additionally, we worked on improving the user interface by adding a drop-down menu for modes. This feature will make it easier for users to select the specific mode they want to operate. Another important task was working on making the feedback work.
Friday, March 10
Today at OpenLab, we began our day by soldering pins onto a board to create a more stable structure compared to using a breadboard. We also started 3D printing one side of the electronics box. As we waited for the printing to finish, we continued working on the interface and successfully implemented a drop-down menu for selecting which mode would be activated. Once the 3D printing was done, we printed two more walls to complete the box.
The goal of this week
The goal of this week is to receive our material and create the first prototype of our device. Then we want to see what can be improved in our prototype and we will probably have to change our design accordingly. We would like to have a finished stop button by the end of the week and improve the look of our interface.
What have we accomplished?
We received our materials and started prototyping. Our setup was too small for the non-return valves and tube to fit. We modified the design accordingly. We also advanced on the code and interface. We created frames and an aesthetically pleasing interface. Additionally, we successfully implemented a stop button on our interface.
What is the plan for next week?
The plan is to print the new design entirely and finish the interface. What still needs to be done is to add a save button in the interface to store a file containing the information of the experiments; such as odors used, mouse number and the protocol number. Ideally, We would like to have a finished prototype by the end of the week with our box in order to start the testing phase.
Monday, March 13
Today we had a meeting in the morning with Dr Gisella Vetere, Maelle and Clement. We mainly discussed what we did during the week and the Arduino interface. They would like us to add the possibility for the user to add the name of the odor (for example, acetylphenone) in the Excel file. In the afternoon, we printed the last wall of our box and were able to see how the electronic would fit in the box. One first problem was encountered. As the soldering board has feet, it is now too tall and so the hole for the power cable needs to be higher. We will also need to do more soldering with arduino pins as they are the ones connecting to the valves and relay. We also continued working on the code and visual feedback. We started our poster to decide the color scheme and template we wanted to use.
Tuesday, March 14
During today's lab session, we dedicated our efforts towards improving our visual interface and website. We incorporated a feedback mechanism that utilizes colour-changing circles to indicate the open and closed status of valves. Additionally, we focused on optimizing the layout and visual appeal of our poster, which included the creation of diagrams highlighting our device's functionality. We also made our website accessible to the public and updated the Arduino page to ensure up-to-date information is readily available.
Wednesday, March 15
Today, We worked on several tasks for our project. Firstly, We focused on the code and implemented a stop button feature, which allows users to pause the program's execution. Additionally, we advanced on the code chart to explain how our code works and make it more intuitive for future modifications. We also worked on the poster for our upcoming presentation. We arranged the text and images, making sure they were aesthetically pleasing and conveyed the necessary information effectively. Finally, we went to the ESPCI to pick up some materials we needed for our experiments. We finally received our tubes and will be able to start prototyping tomorrow.
Thursday, March 16
Today, we continued working on our project, focusing on prototyping with the materials we received from ESPCI. We attempted to arrange the valve with our new tubes, but encountered several issues. The tubes were extremely hard and difficult to bend, which made it challenging to place them into the vials. As a result, we recognized the need to change our design. To address these issues, we brainstormed and created a new potential design. We created a drawing of the new design and carefully measured all the components. We also found a solution for the non-return valve by connecting them to T connectors or more flexible teflon tubes that we have in the open lab. In addition to working on the design, we continued developing the stop button and graph features in the code. We also worked on the code chart using draw.io and made significant progress. To prepare for the next stage of our project and prototyping, we created holes for the tubes in the vial caps and planned to seal them with glue to ensure the system is airtight. We then decided to use velcro to attach the vials underneath, allowing us to easily swap them out and change the odors. Finally, we updated our Gantt chart and cost and materials sheet to reflect the changes we made today and the materials we received.
Friday, March 17
On Friday we redid entirely the new design in Shapr3D, so it is ready to print on Monday. The design is now wider in order to fit the non-return valves and the tubes. We worked on the stop button and finished it. It is now working for both manual and Excel file control. We also created frames in order to organize our interface and make it look pretty.
The goal of this week
This week, our main goal is to finish up the interface and fasten the printing process for preparing our prototype next week. We are aiming to implement frames for different sections and a live graph in the interface. We also want to complete the 3D printing for our prototype. Additionally, we would like to prepare the soundproof box and make the soldering board more organized and modifiable.
What have we accomplished?
By the end of the week, we managed to implement a working graph on the visual interface. As we planned at the beginning of the week, we started 3D printing the new larger design. During the week, we tackled many issues with the 3D printer, however; by the end of the week, we were able to print most of the walls. Furthermore, we worked on preparing a soundproof box by cutting the foam into the right sizes and placing them in the plastic box. We focused a bit on the electronics part as well by changing the soldering board in order to make it more modifiable in the future.
What is the plan for next week?
Next week is the final week of our project so we need to wrap up our setup, complete the interface and test our product.
Monday, March 20
Today, we had a productive meeting with our supervisors and Ph.D. students. We discussed the interface and its requirement of saving information after each experiment. We have decided to implement this feature in our code. Additionally, we deliberated the flow meter quote that we had requested and the necessary pressure scale required for it. We also discussed the protocols and various tests that we should perform after the device is set up. We concluded that our first test should involve checking the odor delivery system and its efficiency. Following this, we will test the length of the tube and the time it takes for odor delivery. Finally, we plan to execute a protocol to evaluate the device's overall performance. In the afternoon, we made some progress on the interface. We added a progress bar that shows the seconds remaining for each experiment. We also identified and resolved issues with the stop button and the excel file. We integrated the frames into the interface and merged it with our new changes. Lastly, we started printing the top half of the box, which encloses the device. We encountered some problems with the 3D printer, but we managed to resolve them.
Tuesday, March 21
At the start of our day, we made progress on our box by printing the remaining half of the top. Additionally, we focused on refining the code chart and enhancing the interface based on feedback from yesterday's meeting. Specifically, we added a new frame named "Information" that enables the user to input the name of the odors, mouse number, and protocol used. Later in the day, we tackled the task of saving this information to a file. We successfully created a file containing the relevant data and programmed a "save" button to initiate the saving process. We also worked on adding the plot of what is happening in real time to the interface. We updated the drafting and Arduino pages on Tikki with the latest content. We also advanced on prototyping with what we already printed.
Wednesday, March 22
Today, we made some progress in optimizing our physical prototype. We cut the cables to the correct length and worked on connecting the Arduino pin to a soldering board. We decided to purchase a soldering board with holes closer to each other, for having better-connected pins. Adrien will be buying it tonight along with some pins for connections. In addition to working on the physical prototype, we uploaded our 3D models onto Sketchlab and added them to the Design page. We also added explanations for each 3D model we have made along the project, which we added to the Drafting page. Furthermore, we worked on the plot in the code and ensured that the file name is visible in our interface. To keep our project on track, we updated our Gantt chart and added the save function to our code chart. Finally, we worked on the Introduction and Setup sections of our poster.
Thursday, March 23
Today, we worked on multiple tasks. Firstly, we advanced on the design section of the poster and advanced on the 3D printing of the box. In the afternoon, we had a meeting with Maelle to show the improvements we have made in the interface since Monday. During the meeting, we discussed the testing of our project. Additionally, we added a property that displays the name of the experiment file selected on the visual interface. Furthermore, we worked on soldering the pins to the new board that was purchased yesterday. Lastly, we placed soundproof foam inside the plastic box to reduce the relay noise.
Friday, March 24
Today we worked on the poster and created two possible arrangements to present to our supervisors on Monday. In addition, we spent time refining the text and deciding what information should be included. We also printed another wall of our device and a stand to support it. The highlight of the day was testing the electrical component, which worked well. All the connections were successful and functioning correctly. Furthermore, we continued 3D printing the sides of the box. As a final touch, we implemented the graph and added it to the interface, enhancing the visual representation of our project.
The goal of this week
Since this will be the last week of BioFabLab, our goal is to finalize the project by completing the assembly of the olfactometer and advancing as much as possible on the poster and tiki wiki before the deadline.
What have we accomplished?
This week, we continued 3D printing the last parts of our design and put them all together. We finalized the interface and worked on some small glitches in the code. We commented on the code entirely and created a README file so it would be easy for the lab to use. We accelerated the construction of the setup and tested the setup using odor solutions. We also tested the entire setup using water and different air pressure to see how the device would hold. We also worked on the poster design, shortening the text and creating new illustrations. Finally, we brought the device to the Vetere lab and explained to them how to use it exactly!
What is the plan for next week?
The project is done! but we will still work on finishing the poster and tiki wiki before the deadline.
Monday, March 27
In the morning we had our weekly meeting with Vetere Lab at ESPCI. During the meeting, we showed different versions of our poster design and asked for their feedback. Additionally, we showed the final version of our interface with the recently added live graph. We obtained the velcro from Clement to stick them below the vials for easier attachment and removal. Then we went to OpenLab to continue 3D printing and work with Arduino. Instead of printing the bottom layer, we thought of using plexiglass so we would save time. To accomplish that, we cut the plexiglass in appropriate measurements using the laser cutter. We continued working on the tiki wiki by implementing the code chart as a slide show.
Tuesday, March 28
As the end of BioFabLab is getting closer we planned on starting the testing soon. For that reason, today we accelerated the construction of the setup. First, we stuck the sides of the walls together and on plexiglass. Then, we created holes in the box for cable connection to Arduino, connection to the air tank, and connection to the arena. We created the same holes on the soundproof foam as well. Once that was done, we placed the electronics on plexiglass. Afterwards, we spent some time working on the poster. The text we have written was too long so we shortened that, we created new vectorized illustrations for setup and we modified some sections. Finally, we worked on arranging the frames on the interface.
Wednesday, March 29
We started our day in the OpenLab by working on the tubing system placed on the 3D-printed box. We had some issues before about bending the PTFE tube since it is very rigid. To solve this problem, we decided to heat the tubes using a heat gun so they would become more flexible. In the afternoon, we moved to ESPCI to test our setup using the odor solutions. During the test we realized that using paraffin was not enough and the tubes entering the vials needed to be sealed with the glue gun since the odor solution was escaping from the cap. Last but not least, we were able to visit the room where the mice are kept in the lab and witness one behavioral experiment.
Thursday, March 30
Today in the morning we faced an issue with the interface so we took some time to tackle the problem. The manual control was not running when the program was launched and it was only running after an experiment was started from a file. To fix that we separated some functions from each other which would help with avoiding conflict. Then, we created a “Reset history” button on the manual control frame so that a new file can be saved with manual commands. Since we made some modifications to the code we updated the code chart. In the meantime, we worked on creating a clear illustration of behavioral conditioning for our poster. Then we tested our entire setup with the working interface and the box, using water instead of odors. Once we realized that the setup was working, we took an explanatory video to put on our tiki wiki. During this process, we took many pictures for our website to enrich our gallery.
Friday, March 31
Today was the last day of the project, it was a busy day for our team as we finalized the olfactometer device and prepared to bring it to ESPCI. We attached the valves and tubes with zip ties and carefully glued the final components in place. Next, we conducted some tests on the device, comparing its sound with and without foam and at different air pressures. After completing the tests, we shifted our focus to working on the poster. We collaborated as a team to ensure that the poster effectively communicated our project. Later in the day, we made our way to ESPCI to present our olfactometer. We were thrilled to share our hard work with the team and provided them with guidance on how to use the device and explain its specifications. Before wrapping up for the day, we set aside some time to plan out our tasks for the upcoming week. We divided tasks for achieving the tiki wiki and poster before the deadline of the 14th.
