RocketLaunchCountdown

RocketLaunchCountdown is a Python + HTML system to operate a launch countdown and Go/No-Go indicator. The Go/No-Go indicator can be driven either from a spreadsheet (CSV export via a share link configured in the Settings window) or from manual buttons in the app. The mode is selected with the radio button in Settings.

Latest release

RocketLaunchCountdown 0.7.0

Features added

• Added ability to change clock once in T+.
• Added Major Concerns display.

OBS instructions

To use the HTML files in OBS (or similar software) as browser sources:

1. Create a Browser source.
2. Select Local file and choose the HTML file you want to display (e.g. countdown.html, gonogo.html, major_concerns.html).
3. Check Shutdown source when not visible and Refresh browser when scene becomes active.
4. (Optional) Install the xObsBrowserAutoRefresh extension to enable timed automatic refreshes.

   • Set auto-refresh times to your preference. Note: very fast refresh rates increase the chance of browser caching issues.

Caution: The xObsBrowserAutoRefresh extension may not have a Mac version.

Install instructions

Install is simple: download the installer, run it, and follow the prompts to install RocketLaunchCountdown.

If you want help wiring this into OBS (example scene setup, recommended refresh settings, or troubleshooting browser-source caching), tell me the OBS version and platform and I can give a short step-by-step.
