Case with Screen

Hi I'm an a-level computer science student who's very exited about the raspberry pi. I'm hoping to use it as a cheep portable Linux box that I can mess around with, without fear of losing lots of money.

I would like to get the raspberry pi in to a case with a small screen built in and a hole to plug in a mouse and keyboard (usb). I have had very little experience with hardware tinkering (but willing to learn), I wondered if any one had any suggestions on how to make this a reality.

Many thanks,

Jack

Was not very useful. I am too looking something like this.

I found some sub $30 screens that are replacements for phones and such. They are cheap, small and have decent resolution (especially the galaxy nexus screen, its 1280x720!). However the big problem is that I would have no idea how you would go about putting an HDMI port on that from them ribbons. I also suspect that it would not be a simple thing either because the processing is also done on some chip inside the phone, but some insight on this would be great. It would be even better if it would be possible to use the touch capabilities of some of these phones for a replacement for a mouse, so then only a keyboard would be needed.

I did find a nice "HD" monitor that was below 5.6 inches but cost over/around $900 but I don't want to spend that much. But this would make the whole process really simple because it just has an hdmi port on it, and i think it also has its own portable power supply.

So what do you guys think?

I am aslo looking for the same type of options. If you find the ways of connecting touch screens, please lemme know.

Many thanks in advance.

I plan on connecting this screen using composite:

And I will use some li-on battery pack to power it and the board (with regulators of course), I don't know if this is possible but from what I gathered it seems it.

@super_tnt

Remember to ask the seller what the native display resolution is. Don't get fooled by the hi res image they put on e-bay

Thank you, hjehg, I might settle for a higher priced screen anyway just to get better quality (hopefully), that one seems to cheap to be good.

Ah, the 7" is a usb monitor, with so far no drivers available for linux.

The 8" http://fit-pc.co.uk/8_HDMIinpu.....t--11.html

is a hdmi monitor...

That 8" one is nice but to pricey for me (I want to rip it out an put into a portable case thingy).

@super_tnt

I agree, but I just wanted to mention it, just in case.

I don't have any links but if you search on ebay "tft vga av" then a list of results shows different sized (2 inch to 10 inch) tft screens and driver boards that allow input from composite and vga and in some case hdmi.

The RCA ones can only have a max of what RCA supports (O-o 320x240 I think?) and normally they are actually half the size.

While the Mimo Monitors (displaylink monitor), are cool, and usb powered, they don't work standalone. They need another monitor hooked up to initialize the GPU. I have one of the first Mimo Monitors. I was going to use it for a double din all in one computer, but like I said, I'd have to have a second actual monitor hooked up for it to recognize right and piggyback onto the GPU.

This said though, these will be running linux, and as such, DisplayLink has an open source linux driver for it. Maybe it can be rewrote to work without a second screen then. If so, that'd be useful.

On a side note, I also have a resistive touch screen I added on top of my mimo monitor. This could probably be used for touch screen input like asked about above. It adds another USB device though, and Mimo Monitors generally need two usb ports to begin with (one for data and power, a second for extra amperage in the power)

Hope this shines some light on some things before you go buying stuff. I'd write/rewrite the drivers to work, but I have no clue about that stuff. (I program VB, C#, and Web languages, so nothing low level enough to work with drivers)

This is a recently launched Kickstarter campaign for a Raspi case with a screen and wireless keyboard. Pretty neat

I think the best deal in most cases is the moto lapdock. if you can swing the price and do the cable mod.
