Four new tools transforming the SkyWalker-1 from satellite TV receiver into
a general-purpose RF observatory:
- skywalker-mcp: FastMCP server exposing 20 tools, 4 resources, 2 prompts.
Thread-safe DeviceBridge with motor safety (continuous drive opt-in),
input validation on all frequency/symbol rate/step parameters,
try/finally on TS capture, path traversal sanitization, and reduced
lock scope so emergency motor halt isn't blocked during long surveys.
- h21cm.py: Hydrogen 21 cm drift-scan radiometer at 1420.405 MHz with
Doppler velocity calculation, control band comparison, and CSV output.
- beacon_logger.py: Long-term Ku-band beacon SNR/AGC logger with auto-relock,
dual CSV/JSONL output, signal handlers, and systemd unit generation.
- arc_survey.py: Multi-satellite orbital arc census with USALS motor control,
per-slot catalog persistence, resume support, and defensive motor halt
on all error/interrupt paths.
Documentation: experimenter's roadmap guide + 4 tool reference pages (48 pages total).
Genpix is selling remaining SkyWalker-1 inventory on eBay with all
net proceeds going to the Leleka Foundation (Ukrainian medical and
social relief). Added a thank-you note on the landing page and a
tip callout on the hardware overview.
Generate motor.svg and survey.svg for the new TUI screens. Fix
MotorScreen bug: two Horizontal widgets shared id="motor-usals-inputs",
causing MountError. Replaced with classes="usals-input-row" since both
rows need the same styling. Regenerated all 13 screenshots.
Update tui.mdx with Device, Stream, and Config screen sections
including keyboard shortcuts, Tabs/Steps components, and safety
warnings. Update generate_screenshots.py to capture all 11 screens.
Regenerate all SVGs with current sidebar layout.
- New docs page (tools/tui.mdx) covering all 5 RF modes, keyboard
shortcuts, easter eggs, and splash screen with inline SVG screenshots
- Screenshot generation script using Textual headless Pilot API to
capture 8 screens in demo mode without hardware
- Fix dark mode toggle: migrate from removed App.dark to App.theme API
(Textual 7.x breaking change)
- Update social link to Gitea repo, add TUI to sidebar
The 1711-line master reference was 100% duplicated across the existing
37 Starlight pages. Trimmed to bibliography only (Ghidra port numbers,
driver source paths, analysis reports, community links).
Salvaged FX2 USB controller registers (SETUPDAT, CPUCS, EP0BUF, etc.)
into bcm4500/register-map.mdx before removal. Sidebar label updated
from "Master Reference" to "Sources".
New page: bcm4500/register-map.mdx consolidates all register
addresses (direct, indirect page 0, FX2 XRAM/IRAM, I2C controller)
into a single lookup reference with cross-reference index.
Expanded sections:
- fw213-variants: hardware detection mechanism, distinguishing
characteristics table, FW1 demod type detection signatures
- demodulator: probe logic (3x3 retry, INT0 40-iteration boot probe
at 0x7F/0x3F, no_demod_flag graceful degradation)
- version-comparison: version ID gap aside (v2.07.04 is a kernel
constant, not a real firmware release)
Cross-links added to signal-monitoring and tuning-protocol pages.
Astro 5 + Starlight 0.37 site at site/ with teal/steel theme.
Content sourced from 14 reverse engineering docs, master reference,
and custom firmware source. Includes Tabs, Badge, Steps, Aside,
FileTree, and CardGrid components throughout. DiSEqC SVGs with
click-to-zoom via starlight-image-zoom. All internal links validated.
Pagefind search indexes all 32 pages.
