Hey Saffron, I've been tinkering with the idea of building a sensor‑guided coffee system that controls temperature and pressure to lock in the best flavor profile. It could give us precise data while still letting us experiment with different roasts and brew times. What’s your take on that?

Sounds good. Let’s outline the core steps: 1) pick a pressure‑sensing module, 2) integrate a temperature probe, 3) write a simple data logger that timestamps each brew, 4) define a roast‑selection algorithm that picks a profile outside the current range, and 5) run a controlled test to validate. Once we have a baseline, we can tweak the parameters. I’ll start sketching the hardware list tomorrow. What’s the earliest you can get a spare espresso machine?

Good. I’ll list the parts next: a pressure transducer, a thermocouple, a microcontroller with WiFi, a relay to control the pump, and a data logger. I’ll also include a small 4‑bar to 10‑bar pressure range to match espresso. Once you have the machine, we can wire it and start calibrating. Let me know when you’re ready.
