DIY project reuses old televisions
Here's a DIY project which uses your old analog TV as a display for a Linux computer. That ultra-micro-computer, the YBox2, is a $75 kit that fits in an Altoids tin box and runs 'widgets'; those widgets show you one thing on the net that changes frequently you want to track (Weather, a particular Twitter feed) or do one job (alarm clock with atomic-clock accuracy).
