T1N-P0T — bioelectric plant MIDI interface

how it works

from root
to rhythm.

sensing

two stainless steel electrodes make gentle contact with your plant’s stem or leaves. they measure bioelectric impedance — the plant’s internal resistance to a tiny oscillating signal.

connectivity

plug in anywhere.

USB MIDIplug into any DAW. class-compliant. zero drivers. TinyUSB composite CDC + MIDI.
BLE 5.0wireless MIDI to phone, tablet, or any bluetooth-capable synth. low-latency.
WiFistreams to the companion app via websocket. real-time sensor dashboard. OTA firmware updates.

built-in audio

no laptop needed.

T1N-P0T includes a PCM5102A DAC running at 44.1kHz / 16-bit stereo and an 8-voice polyphonic synthesizer. plug in headphones or a speaker and your plant is performing live.

reverbschroeder algorithm. space and depth.
delaystereo ping-pong. 50–2000ms. rhythm.
chorusLFO-modulated. width and movement.

interface

one screen. one knob. zero clutter.

a 1.69-inch IPS LCD shows real-time data: current note, scale, signal strength, soil moisture, light level. a rotary encoder navigates every menu. a NeoPixel LED ring provides ambient status at a glance.

materials

aluminum, ceramic,
twenty screws.

laser-cut aluminum 6061 panels, anodized in natural silver. twenty stainless steel M3 screws hold everything together — visible, countable, honest. silicone spacers float the panels above a dark internal chassis. the plant insert is ceramic with proper drainage. every panel removable, every component accessible.
