# 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**:

```bash
# Run pomodoro timer with lobster mascot (25 min work, 5 min break)
cd ~/Bao/TimeToLockIn/HoloClawd-Open-Firmware/examples && uv run --script pomodoro.py

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

# With Spotify integration
cd ~/Bao/TimeToLockIn/HoloClawd-Open-Firmware/examples && uv run --script pomodoro.py --task "LP UPDATE" --spotify-work "spotify:episode:5yJKH11UlF3sS3gcKKaUYx" --spotify-break "spotify:episode:4U4OloHPFBNHWt0GOKENVF"

# Custom timings
cd ~/Bao/TimeToLockIn/HoloClawd-Open-Firmware/examples && uv run --script pomodoro.py --work 50 --short 10 --long 20
```

**Drawing API** (requires holocube_client.py from repo):

```bash
# 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:

```python
from 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 located in the HoloCube firmware repo:

```bash
# Always run from the examples directory
cd ~/Bao/TimeToLockIn/HoloClawd-Open-Firmware/examples

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

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

# With Spotify integration (Andrew's favorite URIs)
uv run --script pomodoro.py --task "LP UPDATE" \
  --spotify-work "spotify:episode:5yJKH11UlF3sS3gcKKaUYx" \
  --spotify-break "spotify:episode:4U4OloHPFBNHWt0GOKENVF"

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

# With trackers
uv run --script pomodoro.py --water 2 --exercise 1 --focus 3
```

**Location**: `~/Bao/TimeToLockIn/HoloClawd-Open-Firmware/examples/pomodoro.py`
- Uses `spotify.sh` in the same directory for playback
- Supports icon-based trackers (water, exercise, focus, pills)
- Interactive command listener for live controls

Options:
- `--task`: 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)
- `--spotify-work`: Spotify URI for work sessions
- `--spotify-break`: Spotify URI for break sessions
- `--water`: Water glasses consumed today
- `--exercise`: Exercise sessions completed
- `--focus`: Focus sessions completed
- `--pills-done`: Mark daily pills as taken

Features:
- Lobster mascot watches you work (focused expression)
- During breaks: happy lobster with twinkling confetti
- Flashing alerts between sessions
- Tracks completed sessions
- Optional Spotify playback via AppleScript (macOS)
- Icon-based trackers displayed on screen
- Interactive command listener via keyboard

## Trackers

The pomodoro timer supports visual trackers using the Kyrise icon pack. Pass tracker values as arguments to display them during your session:

```bash
cd ~/Bao/TimeToLockIn/HoloClawd-Open-Firmware/examples

# Water tracking (glasses consumed)
uv run --script pomodoro.py --water 3

# Exercise sessions
uv run --script pomodoro.py --exercise 1

# Focus sessions completed
uv run --script pomodoro.py --focus 2

# Pills taken today
uv run --script pomodoro.py --pills-done

# Combine multiple trackers
uv run --script pomodoro.py --task "DEEP WORK" --water 3 --exercise 1 --focus 2
```

Tracker icons appear on the HoloCube display with their current counts.

Build and flash:
```bash
git clone https://github.com/andrewjiang/HoloClawd-Open-Firmware.git
cd HoloClawd-Open-Firmware
pio run                    # Build
curl -X POST -F "[email protected]/build/esp12e/firmware.bin" http://192.168.7.80/api/v1/ota/fw
```

## Color Reference

```python
Color.BLACK   = "#000000"
Color.WHITE   = "#ffffff"
Color.RED     = "#ff0000"
Color.GREEN   = "#00ff00"
Color.BLUE    = "#0000ff"
Color.CYAN    = "#00ffff"
Color.MAGENTA = "#ff00ff"
Color.YELLOW  = "#ffff00"
Color.ORANGE  = "#ff6600"
Color.PURPLE  = "#9900ff"
```

## 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
