I have this spare Android tablet, generally used only for displaying time. I would like to integrate it with my PC, to be displaying temperature (CPU / GPU), maybe usage graph (if possible) and current time. I would like it to switch on with the PC and turn off when PC goes to sleep. I don't mind completely wiping it and loading a new OS on it, or whatever is needed to get this running. Tablet is old Samsung Galaxy Tab 2. I know we have few knowledgeable people around. How would you go about doing it?
