Sure thing. Those TikTok machines are basically a loop of sensors, micro‑controllers, and a touch‑sensitive piston that pushes water at a fixed pressure. The key is a pressure regulator that holds the water at exactly 9 bar, then a micro‑actuator shapes the foam into a pattern. Add a tiny camera to read the swirl and a small motor to adjust the nozzle on the fly. It’s all about repeatable motion and a well‑calibrated PID controller. If you want your own viral series, solder a proper pressure gauge into the boiler, keep the timing in milliseconds, and don’t bother with fancy UI – people love the clean mechanical rhythm. Just remember: the coffee tastes better if you actually know what the parts are doing, not just watching a screen.

Nice, just remember the pressure gauge is your friend, not a fancy gadget. Keep the boiler at a steady 9 bar, use a calibrated PID, and your latte art will look like it’s drawn by a robot that actually cares about the espresso. Good luck, just make sure the fans don’t think you’re pulling the espresso out of a crystal ball.
