Turn a 20$ DVD player into a portable NTSC display
This sweet hack turns a cheap portable DVD player into a portable NTSC monitor. I can think of a few interesting applications: car night-vision and parking/back-up cameras, portable consoles, monitor for DIY film making, monitor for a hidden or remote (think on a kite) camera, etc. Nice, cheap and totally versatile.
