What tasks have been completed?
I have successfully designed and fabricated ATTiny44 microcontroller boards for input and output devices. Thank you to Francisco at Beach Lab for the coaching.
I understand the optimal conditions for cultivating aquatic plants for food and biomaterial production. Thank you to Guilherme Simoes in MDEF at IAAC for researching.
I have successfully fabricated composites for the grow tank and the lid for the device. Thank you to Eduardo Chamorro at Fab Lab BCN for helping with RhinoCAM.
What has worked?
The electronics are working well after some study of the datasheets and understanding the different protocols for communication. I had a challenge with the structure as the endcaps both failed in compositing. This was either in the mixing of the resin and the hardener or the application of the resin to the burlap. I have resolved to move on to another way of completing the structure so that most of my time can be dedicated to resolving the electronics.
What questions need to be resolved?
The communication between the DHT11 and the LCD need to be resolved. I am able to read from the DHT11. I need to do that from my ATTiny44 microcontroller board. Once that it completed, I need to send a custom protocol over serial for the DHT11 board to send data and the LCD board to display that data.
The DHT11 is also only good for large spaces. The readings are reliable after an interval of five seconds. I need to be able to show that the device is working and responsive both in MDEFest and the final project presentation video.
What will happen when?
I have added a tracking document to the index page below my project presentation slide and video. This will help me keep track of final project progress and the overall documentation for Fab Academy. I have a few days before local evaluation closes. So, my goal is to continue to develop the project between now Friday, 18 June 2021 and Monday, 21 June 2021.
What have you learned?
I have learned that Fab Academy is not possible alone. We have success stories of young children being able to complete Fab Academy. That has left me feeling like there is something inadequate about myself. This is despite the fact that I have a Bachelor in Humanities and an Associate in Video Game Design. I’m also working on the Master in Design for Emergent Futures. I learned that I should see the value in my own accomplishments and take full advantage of the “abundance” that my world has to offer. I have cultivated many resources and I should not feel alone in anything that I do.
