Merry Christmas world!!! This is a special Christmas 'ible that I'm making based off what I got for Christmas this year. :D
I got a small monitor and small keyboard this year (AA battery for size comparison), and I decided to use it to make a portable(ish) raspberry pi. It's not portable in the sense that it's for on-the-go situations, but it's more portable in terms of not being wired down. The next edition might even be wearable and therefore more portable and on the go.

Step 1: What You'll Need...

Keep in mind that these are the things that I used, you don't need to use these exact products to get similar results.

The list of all materials are:
-a raspberry pi that's ready to go
-a small 640x480 tft car backup monitor
-power jack for monitor
-a riitek mini i8 keyboard
-a 5 volt UBEC module
-a male-male RCA connecting cord
-two alligator clips
-a giant 6 volt battery
-two rubber bands

Step 2: Starting Off

Ok, so to start off, I put the two rubber bands on the battery somewhat in the middle but a little shifted to the right. Then I plugged in the UBEC module to the raspberry pi GPIO pins, positive to pin 2 and negative to pin 6. You can check the chart to see why. Then once that's done, I slid the raspberry pi and UBEC onto the side of the battery whilst using the rubber bands to hold it there.

Step 3: The Monitor

Now onto the monitor. I plugged the power jack into the corresponding plug thingy, then I plugged in one side of the RCA cable to the yellow input jack (the white one was there in case I wanted a second input). Afterwards, I secured the monitor to the top of the battery by slipping the base in between both rubber bands. And to finish up here, I connected the other side of the RCA cord to the raspberry pi's analog output. Now in my case, I was lucky that this 12 volt car monitor was able to nicely run on only a 6 volt battery, otherwise I would have had to remove the internal voltage regulator in the monitor.

Step 4: Aesthetics

Because for some reason, no one likes loose cables and wires hanging out of their "portable" computers. So to solve the problem, I bunched up the cables and stuck them on the back of the battery with the rubber bands to hold them in place. There, problem solved.

Step 5: Finishing Connections

So here is where I finish up with the assembly. I plugged in the much needed USB wifi adapter and the receiver for the small wireless keyboard. I then had to rig up the power connections, so I hooked the power wires for both the UBEC and the monitor with one alligator clip per pole (one for negative and one for positive) so this way there would be less wires. I cannot express the utmost importance that the two gator clips DO NOT TOUCH because that would create a short circuit and on a battery this big, that would be a problem. And finally I plugged the other ends of the alligator clips to the corresponding poles on the battery and...

Step 6: It's Alive!!!

...it booted up perfectly, and in color which is better than the little tv I used to use. All I had to do then was change the overscan settings so that it would fit perfectly in the 640x480 space. All of it worked beautifully, and I was able to start the x server and use a mouse without needing a hub for more USB ports. The last picture is the final product, with the raspberry picture in the background. So yeah, Merry Christmas world, I hope that you enjoyed reading this 'ible and I'd like to see what you make based off this. :D
<p>Hi, can you please list your video settings if possible?</p><p>I have the same screen as you but from the photo's yours is pretty good readable whilst mine is not.<br><br>Thanks!</p>
<p>run this command: sudo dpkg-reconfigure console-setup</p><p>Then choose UTF-8</p><p>Next, choose Guess optimal character set</p><p>Choose VGA</p><p>16x28(framebuffer only)</p><p>Ta-da!</p>
<p>Thanks a lot! Just started working, can't wait to try that out when I'm home tonight.</p>
<p>will it work with any 6v battery or does it have to be the size of a car battery??? does the size reflect how long the battery lasts?</p>
<p>It should in theory work with any six volt battery or battery pack that is able to deliver enough current to keep everything running. Also yes the rule of thumb is the bigger the battery the longer it will last, like these will last about 35 hours for the rasberry pi in contrast to a AA six volt battery pack which could work for maybe an hour or two.</p>

<p>Does the UBEC Power the pi? Thinking of building this but just a bit confused, if it does than this will be a super cheap easy computer for me to make!</p>
yes, the UBEC does power the pi. it has female output pins that fit perfectly onto the GPIO pins, you just have to be careful on what pins they're connected to. but the UBEC turns the 6 volts to a fairly regulated 5 volts. UBECs are cheap also, I think mine was five or so dollars on eBay.
how do you get the raspberry pi to output through vga? I tried editing config.txt, and all i get is a setup screen then nothing. you have my vote if you answer before the contest is over.
my good sir, the raspberry pi has no need of outputting to vga because the small monitor has only an rca input, which the raspberry pi has as one of it's outputs. to see the technical specs of this small monitor, i am giving you the link to the website: http://www.amazon.com/3-5-Inch-TFT-Monitor-Automobile/dp/B0045IIZKU/ref=sr_1_1?ie=UTF8&amp;qid=1388466147&amp;sr=8-1
You have my vote for the contests, and thank you.
plus, it is all seen in the pictures that it does not use vga
Not knowing the power requirements for the monitor, I can't say anything there. I LOVE your proof of concept as it's something I've been planning for a while now. As for the Pi, you could consider going lighter weight on the battery (depending on your needs) and picking up one of those battery back-ups (http://goo.gl/y13XO1 &lt;-- Like that) and hook it into the system to drive just the Pi. <br>Everything is wonderful, though. Love it!
I appreciate your feedback, thank you.<br>As for the monitor, I can tell you that it takes a lot less power than the pi, but I can't tell you how much exactly.
If you dissamble the old tv and put your &quot;Portable&quot; Raspberry Pi inside it would be a great gadget, more &quot;beautiful&quot; and easier to carry.
I considered that, because then it would be be like an old iMac clone, but i wasn't sure if I wanted to either stick it in with the HV stuff or kill the insides to house the newer monitor. But thanks anyways, cool idea.
You can remove everything inside. However if you still want to watch tv there are some usb tv adapters, however I'm not sure if they're raspberry pi compatible.
