remu.ii – Handheld OS Feature Specification Document

Codename: remu.ii A stylus-based ESP32 handheld system for autonomous hacking, anomaly interaction, and cyberpet companionship.

• Device Name: remu.ii
• Platform: ESP32 (WROOM preferred)
• Screen: Adafruit ILI9341 with resistive touch
• Storage: SD card (up to 512GB FAT32) via TFT slot
• Input: Stylus (resistive touch only, no joystick or encoder)
• Power: FuelRod lithium battery (USB-C), physical on/off switch
• Boot: From SD card, dynamic app loader with launcher
• UI Theme: Glitched, terminal-esque, stylus-driven OS with a touch menu to access modular apps

Each app is stored in its own folder on the SD card under /apps/. All apps are loaded dynamically to conserve memory. File structure includes a manifest, assets, and core code.

An AI-driven companion that lives in its own app container. Stylus-only interaction.

• Stats: Mood, Hunger, Loneliness, Entropy, Sleep, Stability

• Interaction: Stylus taps to pet, feed, show

• Entropy Influence: Mood/appearance and UI fluctuates with ambient entropy

• Learning AI: Simple memory and behavior modeling based on user input history

• Customization:

  • Dress-up features (hats, accessories, skins, eyes, antennae)
  • Room decoration and furniture from unlockables

• Persistence: JSON state saving to /apps/digital_pet/pet_data.json

A beat-making engine with glitch and ambient bias.

• Interface: 6-track x 16-step grid (touch-select) effect knobs/toggles (popup or input based)
• Sample System: Load .wav files from /sounds/
• Playback Engine: Real-time, stylus-modulated tempo control
• Preset Save/Load: /projects/*.json
• Visuals: Pixel-glitch animations and BPM pulsing

• SSID scanner with RSSI, channel, and MAC
• SSID spammer (fake APs from list)
• Deauthentication (if supported by firmware)

• Nearby device discovery
• Displays name, MAC, and signal strength
• Logging to /logs/ble/

• Passive RF signal sniffer (if external hardware connected)
• Record + replay function
• Logs saved to /captures/car_keys/

• Signal waterfall or bar graph visualizer
• Logs anomalous spikes with timestamp

Stylus-driven metaphysical contact UI for speculative signal interaction.

• Reads entropy from floating analog pins
• Logs spikes and patterns
• DAC output pulses based on entropy curves
• Graphical representation of detected anomalies
• Stylus taps can modulate waveform (as user signal output)

• Navigate SD file structure
• View text logs, browse folders
• Delete and copy functions

• Adjust screen brightness, auto-sleep, volume
• Load/save settings from /sys/config.json

• Uses USBtinyISP
• Flash Pro Micro, Trinkey, etc.
• Includes diagrams + known bootloader images
