Small program that grabs information from the kernel and some subsystems and displays it on an external liquid crystal display. This way we can easily view the diagnostics for the spectrometer from the control room (or anyplace else for that matter). It was a simple matter to hook this direct-framebuffer application to libvncserver. On the console we run graphical diagnostics that write directly to the frame buffer. X wasn’t reasonable for such a small embedded system, but libvncserver was perfect. The project is an embedded linux box that boots from a compact flash card. It has 10-times the collecting area of the second largest telescope in Effelsburg (maybe near you?). Arecibo is the largest radio telescope in the world (305m!) in Puerto Rico. I’ve been using it for about 4 months on a project to build a new spectrometer for the radio telescope at Arecibo. Jeff Mock of the world’s largest radio telescope in Arecibo sent Dscho a nice screenshot, describing his use of LibVNCServer:
Tim Jansen created KRFB, which is x11vnc integrated into KDE. Karl Runge took Dscho’s first version of x11vnc, which was just a proof-of-concept that the library actually is usable, and turned it into a fully fledged application whose community version can nowadays be found on GitHub.
