Visiting the organic farm - 19.03.2015

We have visited a local organic farm (https://www.facebook.com/sustenta), did research and also got some feedback from the specialists.

Conclusions:

• during the winter, the temperature of the water is 5-8 ºC
• the aquaponic system needs at least 15 ºC to work properly
• we need to heat the shelter only during the winter(the best solution is to use thermal mass)
• we need to find a solution to decrease the power of the sunlight
• we should consider putting the window at the top of our construction(hot air flows to the top)
• price of the PC is much cheaper than we expected(11 €/m^2 instead of 44 €/m^2)

Conductor of the meeting: Paweł

1. Talking about what we have done:
   • We decided about the shape of shelter
   • We gave up heating and cooling
   • List of materials ( mostly )
   • Tasks allocation in work breakdown structure (WBS)
   • task allocation of wiki chapters
2. Questions:
   • What are those topics in State on the Art (Wiki)?
   • If we can got any support with electronic devices from the University (finding better prices, renting the Arduino, etc.)
   • If there is a possibility to get bigger budget?

The meeting was conducted by Pawel. We got some feedback about selecting the materials, the supervisors answered our questions and also gave us useful advices.

Conductor of the meeting: Mateusz

Talking about what we have done:

• Blackbox diagram
• Electronic components electronic_materials.xlsx
• Construction materials construction_materials.xlsx brico_depot_prices.xlsx
• Design

Questions:

• Is the design proper? / Does it meet the requirements of the client?
• Are the electronic and construction materials proper?
• How the midterm presentation should look like?
• What is the deadline for delivering materials list? (hour)

Minute: During the meeting we were given support according to electronic materials and suggestion that we should think about it more. Our client likes our design and idea how it all will work.

Conductor of the meeting: Roland

• changes in the report after midterm evaluation
• changes in the materials list - comparisons
• better electronic schematic

• When we will get materials to work with? (ASAP)
• How the bibliography should look like? (as in this example;references are added in BibTeX format in the refnotes.bib)
• Will we get an access to soldering iron? (to connect wires)
• The list of materials should be for electronic materials and construction materials or only electronic materials?

Minute: We were advised to revise the wiki webpage and to make the list of materials as fast as possible.

Conductor of the meeting: Adriana

• Finish material list
• Changed the electronic map
• Designing the different windows, and adding a new window in the design.
• Starting with the blueprints
• Design the brand logo:

• We are going to have a lux meter?
• The electronic scheme is okay?
• About the connections, using screws is okay?
• We have to use any box template in the blueprint?

Minute: We presented the logo of our product, the supervisors gave us feedback about the electronic schematic.

Conductor of the meeting: Pawel

Agenda:

• Using panels instead of struts
• We built the mock up 1:2
• We started the paper
• Material list: material_list.docx

Questions:

• We are working with small pieces of wood and have to cut it with different angles. In order to put the pieces together in the end it has to be quite accurate. Therefore we are interested in what kind of saws/machines you have in your workshop to work on wood? circular bench saw? Chopsaw? Sliding bevel?
• Are we going to have a glue gun? What size we have to order for the glue sticks? (Is it in your list of materials?)
• We have to do waterproof test on the scale model?

Minute: We got the feedback about the proper units at the material lists. The supervisors also gave us some comments about the wiki.

Conductor: Severin

Agenda:

• We did layouts of the scale model and the simulations. layouts.rar
• Improved the wiki (Although not everything is uploaded to the wiki yet.)
• We worked on a pattern to cut the wooden board in an efficient way.wood_panel.pdf
• List of materials is changed. material_list2.docx
• As Beneditta proposed Adriana calculated the measurements for a Prototype twice the size.

Questions:

• Do we have to buy construction materials on our own? If yes, should we buy them with our money
• How to install the plugins for the wiki?
• Is the prototype with a diameter of 80 cm convenient?
• What about the plastic hinges?
• The proposed board with 2750 x 1220 x 32 would offer enough material for the model. BUT 32 mm of height is way too much. We need a height of around 5 mm.

Minute: We have discussed the material list and got the electronic components. We've got the suggestions from supervisors about the places we can find the materials we need.

Conductor: Reelika

Agenda:

• We did the comparison of the prices of cover material (acrylic glass, PC) in the stores that you suggested
• We have updated the wiki report
• We did the new 3D model for the scale model of the shelter
• We started the paper version of the report, the abstract part is done
• We did the price comparison chart of the two scale models, the old and the new one comparative_price_chart_40-80.docx
• We have done the cutting layouts of the wood in the different scales
• Electronic materials are connected.

Questions

• The price of the electronic materials you have sent us is 58.92 €, but during the meeting you said it will be around 48.00 €. Which price is the correct one? (58.92 €)
• Do you have any good websites with libraries for Arduino?

Minute: We decided that we are going to use PMMA instead of PC. Also finished with the material list.

Conductor: Adriana

Agenda:

Questions

• How should the final presentation look like? What are the requirements?

Answer: 15 minutes including the video

• Is it possible to finish the prototype after the final presentation?

Answer: You can work on details

• Do we have to print the poster and other deliverables?

Answer: Poster and final report must be printed after all corrections have been inserted

• The programme for further development should be uploaded to the Arduino or on the Arduino there should be programme that is needed now? (Further development with servo motors that open windows. Current programme, is only measuring temperature, humidity and telling to close the windows manually if the temperature is too low)

Answer: The Arduino programme should interact correctly with all components provided.

• We would like to test our temperature and humidity sensor whether it works properly or not. Can you provide us with controlled humidity and temperature sensor?

Answer: Define your experiment setup and do the tests.

Agenda:

* Arduino program: shelter_arduino.pdf

* Real model 3D Simulation:

Questions

* How should the Manual look like? What are the requirements?

Minute: We showed our final design. Learned how to write a user manual. We also got all the materials except plastic foil for windows, and hinges which we have to go and buy on our own.

Conductor: Mateusz

Agenda:

• We started building but we have problem. We are out of double sided tape, we need 2 more packages.
• The report, paper and poster are almost finished. Still working on manual, presentation and video.
• The temperature and humidity sensor is broken. Probably because of changed polarity. We have already contacted Paul to test it and figure out how we can solve this problem.
• Changes in the program are done but we need sensor to test it if it works. (The previous program was working properly)
• We need to make some changes in report and paper after the deadline (12.06) because we are not able to do the functional tests before the shelter is finished.

Questions:

• We have to buy the sided tape to have it as soon as possible?
• If the sensor is broken where can we buy another one in Porto? (to do it as fast as possible)
• Is it good idea that the program will ask user to enter the temperature limits when the system starts or is it better to set the limits for most common values and let the user change it while the system is working?
• The real deadline for uploading deliverables is 12.06 or can be 14.06 at night as it is a weekend ?
