What are the most significant risks that could jeopardize the success of the
project? How are these risks being managed? What contingency plans are ready?
HW: Before this week, my biggest concern was not having enough power but I realized that the power supply I use have +30/-30 and 2 A each — and the maximum power rating is 120W. So, I realized that I can just add 30V/2A and -30V/2A to create 120W power source for the circuit. But now, my only concern is that how I am going to build the mounting system and how we are going to integrate the generative mode. If the generative mode taking too long to integrate by the interim demo, we may have to resort to only doing simple-note-playing mode by the interim demo.
Music SW: The concern this week was data transfer. There are ways to send data to an Arduino over serial, but this data generally isn’t marked as anything specific. So, we needed a way to ensure we can read in data and send it down the proper paths (note queue, actuator system, etc.). Generative mode needs a bit of work, but the hope is that it should be done in time for the interim demo (no point in just hoping, though. I’m also working on finishing it and setting up a data pipeline!).
SW (CV): My biggest concern at this point is detecting without environmental interference causing an issue – the plan is to try to switch it to symbol detection. We could have a specific symbol drawn out on a small piece of paper that is then stuck on a hand, for example, that the OpenCV uses to track where they want to signal. This would solve the issue of someone wearing the signaling color or someone in the background wearing it. The contingency plan would to go forward with color signaling, since that is working, and just isolate the environment with a black backdrop.
Were any changes made to the existing design of the system (requirements,
block diagram, system spec, etc)? Why was this change necessary, what costs
does the change incur, and how will these costs be mitigated going forward?
HW: Not yet!
Music SW: Ditto.
SW CV: No.
Provide an updated schedule if changes have occurred.
HW: None!
Music SW: Same!
Software: None, except working to switch to symbol detection this week in addition to the feedback.
This is also the place to put some photos of your progress or to brag about a
component you got working.
HW: I was able to power three solenoids simultaneously!
Music SW: Nothing to see, but I set up some pretty nice data structures for data transfer, at least in my opinion.
SW: Looks cool on video, but image captures don’t look much different. Both normal note generation and generative mode is working and you can switch between them which is cool!!
