I have the RPi setup with 1600 ma/h battery, two solar panels, BT keyboard and trackpad (2.5 in by 5 in) and it all fits in a nice box I can carry around that is just 3 in by 6 inch.
I would love to find a cheap 4 to 7 inch lcd with HDMI in, 5v USB or battery powered that I can add to my portable Pi kit.
What lcd screens have you tried? I have looked on Amazon and eBay for cheap portable TV's but the closest battery powered one I found had composite input. No hdmi inputs out there that I could locate...
Any luck from anyone else?
