I did a custom car pc movie player mod using a ThinkPad 600X. I went to ebay and purchased a wireless remote: http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN:IT&ih=022
I'm trying to figure out the best way to power it when built into the laptop. I have made some amazing mods to this laptop already and tested them. The first thing was to reverse the pcmcia cage so I could install a 4 port usb 2.0 card and not have anything stick out of the laptop. I then removed the usb interface ports and soldered on usb interface cables. I also added a wireless N usb card, bluetooth, wireless presenter mouse, RF remote receiver, and S-video/Composite output ports all internally so the laptop looks exactly the same cosmetically as before the mod. Everything works and I am attempting to connect it to the input A/V ports on my new Honda Odyssey so my kids can choose any movie on the fly without having to carry a ton of DVDs. So far, everything is tested, media software is installed, media remote works, the only thing I have issues with is the damn power switch. I can set the power down time through windows, but obviously I can't turn it back on remotely. After buying this remote from ebay, I have been trying to think of the best way to install the receiver into the laptop. Ultimately, I would like to be able to grab this laptop and use it separately from the van when on vacation and don't have access to TV. The remote receiver needs a 12vdc, 6mah power source. I could hook it into the car battery, but that would mean separate cables and I would like to avoid that if possible. The preferable method would be to hook it up to the internal laptop battery but it only has a 10.8vdc output. If you are interested in pics or details, let me know.
