WORK ACCOMPLISHED:
This week the primary focus for me was building the encasing for the device that we’re attaching to the back of the bicycle. We went through with 3D printing an initial model, but it didn’t fit all our building materials. We were planning on 3D printing another encasing for this, but we decided to move forward using acrylic as the material and using heat bending to form the case. So I made the 2D specifications for the case and laser cut the Acrylic. Acrylic was a good option since it’s durable and allows us to check into the device to ensure that everything is working properly. I also did some drilling to adjust the port positions.
Another focus of mine this week was connecting our new bluetooth device with our Raspberry Pi. In order for this to work we had to change the Google API we were using for text to speech and speech to text. I created a working script for the usage of this new API, which Akintayo was able to integrate into our navigation script. I had to change the configuration profile for our bluetooth in order for both the serial bluetooth and the bluetooth headset to work in unison.
NEW KNOWLEDGE:
When I first started this project, I had very little knowledge of the tools that would be used. The first tool I had to work to understand was the Blues kit, which was the first device we were going to use for GPS tracking / cloud information. I had to look through forums such as stack exchange, blues webpages, and youtube videos to figure out how to integrate the blues notecard with the Raspberry Pi. After we pivoted to the new GPS device there needed to be an understanding for UART connections on the Raspberry Pi, which I had to figure out through youtube videos. Then when working with the bluetooth devices, serial connections, and Arduino, I had to look through web pages , youtube videos, and webpages as well. However general knowledge such as wiring and usage of breadboards was previous knowledge learned from classes like 18-100 and 18-220.
PROGRESS:
Currently I have accomplished what was expected of me from this point, however more testing needs to be done which is what we are currently working through.
Next Week Deliverables:
Wholistic testing of the device to ensure things are moving as planned. As well as addition of additional features if things are working smoothly. We also need to finish the final poster and work on presentation slides.
