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?As of now, we think our main risks will be related to noise sensitivity and light interference. While we do not fully know these risks until our parts arrive, they are being managed currently by having a wide array of options to test in our system. For example, we have multiple different light sources either ordered or in a backup list to order if needed. Overall, our IR protocol will function somewhat like a TV remote. Because of this, we have some documentation available for potential risks and these will help us to mitigate issues as they arise. For the IR components, our contingency plan is to try to switch to a more well documented transmission protocol, like RF. For something like our microphone, our contingency plan is to switch to a more reliable high sensitivity bone microphone and mitigation plan is to perform basic pre-signal processing if we have too much noise.
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? The only change we made so far is ordering 950nm LEDs instead of 1450nm. We plan on using the 950s for testing and then switching to 1450nm. Originally we had planned on 1450nm the whole time but they are expensive and we didn’t want to throw budget away for testing parts. After more research on LED safety, we know that 950nm LEDs are also safe. But because of some potential added risk, we are now definitely adding IR filters as a fail safe. No other main changes were made to the overall design system. However, we were able to get 8GB RPis (which is something we were debating), giving us more leeway to put on larger software processes. Because this was loaned to us, there is no cost to our budget or design.
