does anyone know if eio.com still has any 6" lcds? and know how to put it all together?
As far as I know, they still have them. Check <a href="http://www.eio.com/colorlcd.htm">http://www.eio.com/colorlcd.htm</a>. Powering and interfacing them is somewhat more difficult, as getting it to accept VGA input is near impossible (without buying a $150 scan converter), so you'll need a video card with TV out. There's a lot of info on the page, so just be patient and persistent.
I know you can get cards with TV out at www.pricewatch.com (you can get anything for really cheap there) . How hard is it to hook up the backlight inverter and power supply? Do I have to make a cicuit or do I just have to soldersome things together?
I'm not sure, but I think there's someone out there selling kits with the backlight inverter and power supplies, but if I remember correctly, he was charging like $250 (display included). Check the page I mentioned above, it's very badly organized but has a lot of useful links.
