This simple windows app keeps a machine/workstation from going idle. Oriignally this application pressed the Scroll Lock button twice every second to keep windows "awake". The recent version now uses a native windows call "ES_DISPLAY_REQUIRED" to keep the display on instead.
I built this tool to solve a problem, learn about tkinter, pyautogui and python threading. Displaying a basic GUI while a second thread takes care of the automation. Whilst the latest version is much more efficient/compact, you can still see that code in as recent as the v0.4.0 tag.
The App starts in the system tray (with the Z icon).
A right-click context menu allows you to "Start/Pause" the program (pausing will allow windows to sleep again, this is represented by ⏸ icon) or "Quit" and close the application.
