The biggest risks to our project right now are shipping delays or receiving parts that are dead on arrival. Since the semester is short, a delay of two or three weeks to get a replacement part could make us miss our deadlines. To manage this, we ordered all our important components early rather than waiting. About half of our parts have already arrived, and we are testing them immediately to make sure they work while we can still return them. Our budget is also very tight, so if we accidentally break an expensive part and cannot afford a replacement, our backup plan is to build a simpler frame using scrap materials instead of buying new materials for a polished enclosure.
We made a few changes to our system design this week to improve reliability and safety. First, we updated our electrical plan to use a specific, high-quality power supply instead of a generic one. This costs about $15 more, but it is necessary to stop sudden power spikes from shutting down our main computer when the lights turn on. Second, we updated our system diagram to verify exactly where the physical frame sits in relation to our electronics. This change didn’t cost anything, but it was necessary to ensure the wooden frame is strong enough to support the entire hologram system.
