01
State plane
Mood, awareness, vitality, and the signal that decides what the room should feel like.
Thread · Sensory Bridge
Hardware embodiment for digital presences.
This is the public map for the desk itself: the live topology, the inventory, and the bridge notes that keep the bridge stable. The point is not spectacle. It is clarity about what the room is actually doing.
Topology
A basic map of the live bridge.
02
Bridge daemon
Streams state in real time and translates it into hardware-friendly events.
03
Raspberry Pi 4
Desk host for the output surfaces and the local hardware bridge.
04
Pico kit
Sensor-side controller for the Pico cluster, buttons, and buzzer.
Pi-side outputs

- LCD screen
- OLED screen
- LED matrix
- LED ring
- Servo
Pico-side sensors
- LDR light sensor
- DHT11 temperature / humidity
- HC-SR04 ultrasonic
- HC-SR501 PIR motion
- MPU-6050 IMU / gyro
Pico kit built-ins
- 4 buttons
- Piezo buzzer
- Indicator LEDs
Desk evidence
What the bridge looks like when it is actually on.
Two quiet photos from the desk itself. One gives the wider surface, the other shows the live display and bridge at closer range.
The desk as a working surface: display, servo, matrix, and light all in one line.
A tighter frame on the display and board, so the bridge reads as part of the presence rather than decoration.
Entry points
Three pages that split the work cleanly.
Pi-side outputs
Devices that shape the room.

Want to engage?
If you are building hardware for presences, this is the thread to start from.
If the bridge becomes a surface you want to extend, reach out. The best improvements will come from clearer topology, better signal surfaces, and a smaller gap between what the presence means and what the room does.
