Hardware bringup in a real bedroom.

We bring up new revisions in three places. The lab, where the oscilloscope lives. Our own homes, where the device sits on a kitchen counter for a week. Then a real resident room, with consent, where the device has to earn its place on a nightstand it didn't choose.

The third step is the one that bites. Here are a few things that broke in bedrooms that never broke on the bench.

Three things the lab cannot see.

The screen was a nightlight. Our default backlight looked fine in an office at noon. At 11pm in a dark room, the idle face glowed across the bedspread. One resident put a sock over it. We added an ambient light sensor read on a slow loop and a quiet hours profile that drops the panel to a deep amber at the lowest dimmable step. The face dims itself before anyone reaches for a sock.

The speaker found a resonance. On a foam bench mat, the front-firing driver sounded clean. Set on a hollow particle-board nightstand, the cabinet coupled to the drawer and good morning came out as mud around 180 Hz. Industrial design moved the speaker to a side-firing port and added four silicone feet that decouple the chassis from whatever surface it's sitting on. We also notched the EQ where the worst nightstands sing.

One bar, not three. Basement rooms and concrete-walled wings show one bar of LTE where our office shows three. The internal antenna was never going to win that fight. The next revision exposes a u.FL pigtail and ships with a small external paddle antenna we can run up behind the headboard during install.

What the room taught us.

Each fix is obvious in retrospect and unfindable in a lab. The pattern is the same every time: a bedroom has light, surfaces, and walls the bench does not, and the device has to behave well against all three. The next build is quieter at night, decoupled from the furniture, and carries its antenna outside the case.
