This week I will be finishing up the next iteration of the CAD designs and fabricating them early in the week, likely Tuesday. I will also further look into the OLED driver to decrease latency further, and also start work on integrating the battery.
This week I will be updating the CAD designs and sending them off for fabrication again. Once new parts come in, I will have to do further soldering and wiring to hook up the microphones. I will also start work on the battery module.
This week I will be sending off the CAD design for fabrication since many changes were made last week in the design. I will also be working on the display driver and connecting the Mic array to the MCU.
As anticipated last week, my time this week was tight due to midterms and other class commitments. However, I was able to successfully do the MCU bootstrapping and toolchain setup. This week I will be sending off the CAD design for fabrication, but more importantly I will be wiring everything up in order for the others to develop. We are currently working with 2 microphones and I hope to have all 4 microphones wired up this week. I will also start work on the display side of things after the wiring setup is complete.
Parts have nearly completely all arrived, however the most important part, the MCU, is still in transit. This has caused us to go a bit behind schedule. This week I will be modularizing the rest of the CAD design (I have a optics module mostly set), and running tests on the optics and microphone systems. The MCU is scheduled to arrive early in the week, and I will put most of my focus on bootstrapping it for development so that I can hand it off to Ram and Will, allowing us to have synchronized toolchains and the ability to work in parallel.
This coming week I do have some midterms so time might be tight. If I’m unable to do my the MCU bootstrapping and toolchain setup, I’ll hand it off to the others.
We’re running a bit behind schedule, so I’ll be trying to catch us up. Primarily I will be looking to finish up our circuit design schematics, as well as iterate on the CAD design. The goal is to have the design in a modular form next week, even if the individual modules are still rough.
This week I was working on doing research on speech separation hardware requirements, which connected with the BOM selection work our whole team was working on. I specifically did research into the requirements on the MCU front, and as a result of this research have decided on some of the hardware specifications for our board. I also worked with Will and Ram to determine the specifications needed for microphones in order to interface with our target board.
In terms of schedule, I’m mostly on schedule with our initial planned schedule. The rate of progress on my part with the BOM work seems to be slow though, and although I anticipate being able to finish by our preset deadline, it would be close to the deliverable date.
This next week, my deliverables include a completed BOM (preferably by Tuesday), as well as some block diagrams for our system architecture design.
