“So\u2026 we’re building a ghost.”<\/strong><\/p>\n\n\n\n

That was basically the vibe when we kicked off our project. Our mission? Bring Joseph Priestley \u2014 an 18th-century scientist most people have never heard of \u2014 back from the dead. Well, sort of. We’re creating an AI-powered interactive experience for the Priestley-Forsyth Memorial Library in Northumberland, Pennsylvania, and our job is to make teenagers actually care about a guy who’s been gone for over 200 years.<\/p>\n\n\n\n

Our first week was a whirlwind of “who is this guy?” and “wait, he invented soda water<\/em>?” The design team dove headfirst into Priestley research, and honestly, the deeper we went, the more fascinating he became. This is a man who discovered oxygen (well, he called it “dephlogisticated air” \u2014 try saying that five times fast), accidentally invented carbonated water while living next to a brewery, and was basically the 18th-century version of a controversial tech disruptor. There’s a lot to work with.<\/p>\n\n\n\n

On the design front, we held our first brainstorming sessions and drafted up a question list for our clients \u2014 Jeff Johnstonbaugh, the Library Director, and Harry Lewis, our Priestley history expert. We needed to understand not just what<\/em> to build, but why<\/em> it mattered to the community.<\/p>\n\n\n\n

Meanwhile, our programmers weren’t wasting any time. By the end of Week 1, they had a working pipeline: text input \u2192 local LLM \u2192 local text-to-speech. That’s right \u2014 you could type something, and a locally-running AI would respond in a synthesized voice. It wasn’t pretty yet, but hearing “Priestley” speak for the first time was a genuine goosebumps moment. We also got our hands on a Looking Glass holographic display and started the initial setup \u2014 because if you’re going to summon a ghost, you might as well make him look the part. <\/p>\n\n\n\n

The big takeaway from Week 1: the technical foundation is possible, the history is richer than we expected, and this project has the potential to be something truly special. Now we just need to figure out\u2026 everything else.<\/p>\n\n\n\n
