Max, when looking at your display panel, I somehow envision the LEDs having those jeweled lenses that were originally used on 1960's era panel lights. I think Dialight was the most prominent supplier. Have you considered using anything like that for the "vintage factor"?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
