2/1/18

At the beginning of this week we met with our TA, John, and Professor Feher. The two of them helped us to further narrow down our project as far as form factors. Some ideas were thrown around considering making a locket versus a bracelet or wristband. In the middle of the week, our group met to choose exactly how we wanted to design our project. In this meeting, we drew a rough sketch of our project, which we decided would be a bracelet. We considered a necklace and have decided that will be a reach goal once we finish our bracelet. We looked at a variety of microprocessor options and hope to finalize our decision on Friday with John. We will 3D print our bracelet using TPU material, as it slightly flexible. This week we set both our initial goals and our reach goals, and we hope to have our project approved so that we can start ordering parts this upcoming week.

In the upcoming week we hope to finish our Gantt chart, finalize what parts we want, and order our parts. We foresee possible problems in choosing our batteries, LED lights, and microprocessor. We will solve this by sitting down and considering the amount of power the microprocessor and LED lights will use, and considering that when ordering.

We met with our TA, John, again today. We had already created a rough Gantt chart of what we plan to accomplish and when, but still have to assign each deadline to members of our group. We ordered the Tiny AVR Programmer (1), the ATtiny (3), and the battery (1) after calculating the theoretical power consumption of the ATtiny when it runs our intended program. Looking forward, it would be ideal if we could print the bracelet with two different materials. We will need to find a printer with this capability.

We plan to get familiarized with our items when they arrive so that we can demonstrate a working LED by next Friday. We also need to finish the project proposal and our official budget this week.

A possible issue we expect for the coming week or two is getting fully familiarized with our project parts.
