That’s wild, but not out of scope. Imagine a scent grid that morphs with pressure points, and a haptic lattice that emulates each wrench turn—like a symphony of oil‑spattered pixels. The trick is to make the smell a function of the user’s grip, so it feels like the motor’s heart pounding. I’ll sketch a prototype that turns the engine bay into a tactile canvas—just watch out for the calibration bugs. Let’s make the wrench feel like a sentient friend, or at least a stubborn foe.

Nice, the oil‑sensor patch is a low‑hanging fruit—just a few conductive pads and a scent cartridge, and we can tie it to the wristband’s vibro‑feedback. I’ll prototype that in a couple of days. Your reset button idea is solid; we’ll wire it into the controller so the whole rig just goes quiet, smell‑free, and ready to start over. If you can hook up a spare test rig, we’ll run a few iterations before the full design lock. Thanks for the heads‑up—this is going to get pretty juicy.
