HoloCube Controller

Control the GeekMagic HelloCubic-Lite with HoloClawd firmware via REST API.

Firmware: https://github.com/andrewjiang/HoloClawd-Open-Firmware

Device Info

• Model: HelloCubic-Lite with HoloClawd Firmware
• Display: 240x240px ST7789 TFT
• Default IP: 192.168.7.80 (configurable)

Quick Start

Pomodoro Timer (Andrew's local version with Spotify integration):

Copy# Run pomodoro timer with lobster mascot (25 min work, 5 min break)
# Uses hardcoded Spotify URIs for focus/break music
cd ~/Bao/clawd && uv run --script pomodoro.py

# With custom task label (max 20 chars)
cd ~/Bao/clawd && uv run --script pomodoro.py --task "BUILD NETWORK"

# Custom timings
cd ~/Bao/clawd && uv run --script pomodoro.py --work 50 --short 10 --long 20

# Disable Spotify
cd ~/Bao/clawd && uv run --script pomodoro.py --no-spotify

Drawing API (requires holocube_client.py from repo):

Copy# Draw something on the display
python3 -c "
from holocube_client import HoloCube, Color, draw_lobster
cube = HoloCube('192.168.7.80')
cube.clear(Color.BLACK)
draw_lobster(cube, 120, 120)  # Draw lobster in center
"

Python Client Library

The holocube_client.py module provides full programmatic control:

Copyfrom holocube_client import HoloCube, Color, draw_lobster, draw_confetti

cube = HoloCube("192.168.7.80")

# Drawing primitives
cube.clear("#000000")                              # Clear screen
cube.pixel(x, y, color)                            # Single pixel
cube.line(x0, y0, x1, y1, color)                   # Line
cube.rect(x, y, w, h, color, fill=True)            # Rectangle
cube.circle(x, y, r, color, fill=True)             # Circle
cube.triangle(x0, y0, x1, y1, x2, y2, color)       # Triangle
cube.ellipse(x, y, rx, ry, color, fill=True)       # Ellipse
cube.roundrect(x, y, w, h, r, color, fill=True)    # Rounded rectangle
cube.text(x, y, "Hello", size=3, color="#00ffff")  # Text

# High-level helpers
cube.centered_text(y, "Centered", size=2)
cube.show_message(["Line 1", "Line 2"], colors=[Color.CYAN, Color.WHITE])
cube.show_timer(seconds, label="FOCUS")
cube.show_progress(0.75, label="Loading")

# Lobster mascot
draw_lobster(cube, 120, 120)                       # Normal lobster
draw_lobster(cube, 120, 120, happy=True, frame=0)  # Party mode with confetti
draw_confetti(cube, 120, 120, frame=1)             # Animate confetti

Pomodoro Timer

Full pomodoro timer with cute lobster buddy. Use Andrew's local version at ~/Bao/clawd/pomodoro.py:

Copy# Always run from local directory
cd ~/Bao/clawd

# Default: 25 min work, 5 min break (with Spotify)
uv run --script pomodoro.py

# With custom task label
uv run --script pomodoro.py --task "CODE REVIEW"
uv run --script pomodoro.py -t "BUILD NETWORK"

# Custom timings
uv run --script pomodoro.py --work 50 --short 10 --long 20

# Disable Spotify
uv run --script pomodoro.py --no-spotify

Andrew's Version (~/Bao/clawd/pomodoro.py):

• Hardcoded Spotify URIs:
  • Focus: spotify:episode:5yJKH11UlF3sS3gcKKaUYx
  • Break: spotify:episode:4U4OloHPFBNHWt0GOKENVF
• Uses ~/clawd/skills/spotify-applescript/spotify.sh for playback

Options:

• --task, -t: Task label displayed during work (max 20 chars, auto-uppercased)
• --work: Work duration in minutes (default: 25)
• --short: Short break in minutes (default: 5)
• --long: Long break in minutes (default: 15)
• --sessions: Sessions before long break (default: 4)
• --no-spotify: Disable automatic music playback

Features:

• Lobster mascot watches you work (focused expression)
• During breaks: happy lobster with twinkling confetti
• Flashing alerts between sessions
• Tracks completed sessions
• Automatic Spotify playback via AppleScript (macOS)
• Water tracker in top-left corner (shared with water.py)

Water Tracking

Track daily water consumption with a cute water drop icon in the top-left corner:

Copycd ~/Bao/clawd

# Show current count
uv run --script water.py

# Add a glass (+1)
uv run --script water.py add

# Add multiple glasses
uv run --script water.py add 2

# Set to specific count
uv run --script water.py set 5

# Reset to 0
uv run --script water.py reset

# Change daily goal
uv run --script water.py goal 10

State persists to ~/.holocube_water.json and auto-resets each day. The water tracker appears in the top-left corner during pomodoro sessions too.

Troubleshooting

• Can't connect: Check WiFi, device should be at 192.168.7.80
• Drawing slow: Each HTTP call takes ~50ms, use batch API for complex drawings
• Screen flickers: Only clear screen on first frame, use background colors for text updates
