  • Tablet as a touchscreen monitor

    Hello! I've not seen this particular subject discussed here via a search but please forgive me if it has.

    I'm in the process of building a car PC and would like to use an existing Windows or WebOS/Android tablet as the touchscreen monitor. The screen quality is very good on both and I would have the added benefit of being able to take it with me and use it outside of the vehicle. The primary use for the car PC would be to play audio files/playlists through my existing sound system and also use GPS functionality.

    The tablets and PC have Bluetooth and WiFi for communication but my preference would be the former (using a PAN), to avoid having to set up a wireless ad hoc environment in the vehicle. However, I'm not a network expert and there probably is a way to do this without too many issues. Since I don't want to stream the audio through the tablet (as most RDP software does) I'm having a difficult time finding an application that will allow control of the PC from the tablet (as a touchscreen) but still send the audio from the PC to the sound system.

    I checked out Splashtop but that only supports WiFi. Given the explosion of technology lately this should be an easy problem to solve, but clearly I'm missing something. Any ideas?

    Thanks!

      Just find a 12v or 5v router and install in your car. That would be my best suggestion. SNO

        That's very similar to what I have planned. I'm going to be dropping a linux PC in the trunk as my music "tank" along with an wifi access point if I can't get a supported card under linux easily running as the access point. Linux will run SubSonic on it in a jukebox style mode, and I'll be using my iPhone and/or other tablets to control playback as well as stream content to them for other passengers if they don't like my tunes.

        I like your idea, like to see where you take it.

          Yeah, it's looking like the WiFi router is the way to go. I'm considering the D-link DAP-1350, due to its small size and versatility. Splashtop allows the audio to be streamed from the server (car PC) as well as the client (tablet), which is what I want. Any other router options would be appreciated.

          Will keep you posted as I move forward with this!

            I once had an access point about that size, but it had the ability to be powered off USB. I'll see if I can dig it up, I think it was an encore device.

            EDIT: Actually, here's an interesting one I just came across... http://www.kanexlive.com/myspot

              Something like this, perhaps?

                these are sold on ebay and have DD-WRT preinstalled (I bought a couple - they work):

                  So are these devices used as an ad hoc network or do they assign an IP address via DHCP? My car PC does have a Gigabit port, so it would be no problem setting up the wireless security parameters. Sorry if I'm missing something!

                    With DD-WRT you could configure it with DHCP and more than likely could setup the wired NIC as local LAN so it basically turns it into an AP with DHCP capabilities. I'm gonna have to get a couple and check it out.

                      OK, this looks interesting.

                      I'll admit I'm a total noob at this kind of stuff. But since the TP-Link device has a USB port, could you not put in a large USB stick, or a USB hard drive and access that from your tablet through Wi-fi? Would having the CarPC be even required, if all you wanted it to be was a music server? Just a tablet accessing the stored music on the USB drive plugged into the TP-Link?

                        The USB port is for 3G dongle I believe...

                          It is, but with DD-WRT, you should actually be able to use a mass storage device in that port if you wanted to. Might have to flash to a later version of DD-WRT. I have one ordered so I'll test that very thing if nobody gets to it before me.

                              So I purchased the D-link DAP-1350 and installed Splashtop on my PC and tablet. The D-link router works great but Splashtop is tough to use on the tablet, as it doesn't take up the full screen. It does play audio from the CarPC as if I was using a touchscreen monitor, which is something Windows Remote Desktop can't do. Although I could make it work I would really like to find an app or software that would be more seamless. Any input is appreciated!
