This is a quick and easy project to build a portable Raspberry Pi computer that fits right in a lunch box. It's a good first Pi project since it requires no coding, soldering or tooling of any kind. All you have to do it acquire the parts, plug everything in and secure it in the lunch box.

The Raspberry Pi isn't a very fast machine, but it IS extremely versatile and easy to use. This rig will have all the functionality of a wifi netbook, if a slow one with a very small screen.

There are lots of ways to do a project like this so feel free to deviate from my plans. All of the parts are modular and you can change its abilities a bit by using different parts.

EDIT: While I used a Raspberry Pi model B in this instructable, I would advise folks to use the Model B+, it uses less power than the Model B which sometimes can't run both the Wifi and Bluetooth dongles.

Step 1: Parts List

Here is the list of parts I used. Please note, these are the first one's I found for each item, if you shop around you can probably pay a bit less. Also, feel free to swap out components, like different size batteries or screen. All of the bits are modular.

Total Price $200 + shipping with these items.

<p>I made a few modifications (Moved the screen to the lid, put the keyboard and mouse in such a way that they could be stored in the lunchbox when not in use, etc), and it turned out quite well. This was a fun project to build. </p>
<p>I love it! Nice build.</p>
<p>The lcd screen link does not work can you please link me to a working link?</p>
<p>Would a Raspberry Pi 3b work for this project?</p>
<p>Yes, of course! It will be even better since it has built-in WiFi.</p>
<p>Thank you so much for all of your help. I am hooked to Ras Pi now!</p>
<p>Love it!</p>
This is all that shows up. Lasts a second and then goes black
<p>Sorry I missed this one earlier. If that screen shows up then goes black it means that the screen isn't getting a signal. Make sure you are using the right cable and that your Pi is set to use composite video in the NOOBs configuration file.</p>
<p>Hi! I really want to make this but I don't know much about electronics- I have a few questions - why do you need 2 batteries? Is it essential (meaning do I NEED to order 2? Can I do without?</p><p>Thanks in advance!</p>
<p>The screen and the Raspberry Pi use different voltages. You can use a single 12v battery, but it's a little more tricky. You'd need to use a voltage regulator to give the Pi something it can use:<br>https://www.amazon.com/Eathtek-Converter-Double-Regulator-Voltage/dp/B00UUTB26W/ref=sr_1_2?s=aht&amp;ie=UTF8&amp;qid=1469733083&amp;sr=1-2&amp;keywords=12v+to+5v+usb</p>
<p>Thanks! Also, does it matter whether the 12v battery is Li-ion or Li-po?</p>
Not usually.
<p>also how mutch storage does it have</p>
<p>Depends on the size of your SDcard, generally 16, 32, or 64gb. You can also add additional storage with USB thumb drives or even stick an SSD in it. Unless you want to store media like movies, you really don't need very much space. The OS is really small, and the remaining space on the SD is usually more than you will need for general computing.</p>
<p>can you dounload google or any search engines on it</p>
<p>You can browse the web and use google. Raspbian is a full OS, like windows but a bit lighter. It's got all your standard stuff like a web browser and word processor and such.</p>
<p>I did this for about half the price</p>
<p>That doesn't surprise me, this is sort of a guide on how to go about it, but there are numerous parts you could use instead to achieve the same end. I used this part set because I already had all of them lying around my shop.</p>
really awesome project, but D10D3 do u mind uploading or sharing link of that wallpaper, its awesome....my launchbox needs that wallpaper.....
<p>um I was looking through the materials and some of them do not exist any more</p>
This will be an ongoing issue for this sort of project. These exact models may not be available but it shouldn't be hard to find equivalents of each piece.
<p>Would this display work instead of the one you have posted? Is it compatible? http://www.amazon.com/OFFICIAL-RASPBERRY-FOUNDATION-TOUCHSCREEN-DISPLAY/dp/B0153R2A9I/ref=sr_1_1?ie=UTF8&amp;qid=1458958567&amp;sr=8-1&amp;keywords=raspberry+pi+touchscreen</p>
Midway through making this, but having issues with my composite screen. The pi works just fine with an HDMI (my tv) but does not pick up the composite screen no matter what. I've tried tons of different things and read every forum I could to figure out why, but no luck. The screen flashes blue with 'AV1' in the top corner before going black again, completely unresponsive. Is it supposed to do this? How can I fix it? Any suggestions would be great.
It sounds like either the Pi isnt configured to output composite, or you might have the wrong composite cable. Take a look at the comments below where both problems are looked at, might be an answer there.
<p>Already tried all of that. I'm using the B if that clears anything up. I'm using the exact screen and battery listed above, so I'm pretty sure they're not the incorrect ones.</p>
This is all that shows up. Lasts a second and then goes black
<p>Awesome!</p><p>totally unrelated, but does anyone know how to get metasploit on kali linux? i downloaded an ARM image of kali that doesnt come with metasploit and i have no idea how to get it.</p>
<p>apt-get install metasploit kali</p>
<p>but wouldn't that mean &quot;install metasploit and kali&quot;?</p>
<p>it says metasploit isnt a real package</p>
<p>Try this:</p><p>http://www.darkoperator.com/installing-metasploit-in-ubunt/</p>
<p>Awesome lunchbox!</p>
<p>Great Project! My friend and I 3D Printed a case for our project. I like the idea of 0% soldering because all the other Raspberry Pi Computer tutorials required Soldering. I also added a 64 GB flash drive for external storage.</p>
<p>does the ras-pi come with a Universal Serial Bus port?</p>
Yeah, the Pi B+ and 2B have 4 USB ports.
<p>SWEET!!!</p><p>Yessss haha yay</p><p>and does raspbian OS have a text-based command line?</p><p>if so, im DEFINITELY making 1</p>
<p>you can boot to either command line or the GUI. Both are fully usable. </p>
<p>I love the way your delete key says &quot;BS&quot; on it. Yes I do know what it REALLY stands for, but it's funny anyway :-)</p>
<p>haha lol</p>
<p>just wondering, did you have any problems with overheating, and if I make a slightly larger version, will I need to use a computer fan</p>
<p>No, Pi's run really cool. No need for active cooling. If you are worried about head they sell little aluminum stick-on heat sinks you can put on the CPU and graphics chip.</p>
<p>what os did U guys use</p>
Generally I run Raspbian on my pi systems.
<p>Hello all!</p><p>I cannot seem to get the video to output onto the lcd screen. I tried editing the 'config.txt' to set the video output to &quot;sdtv_mode=2&quot; with no avail. Any ideas?</p>
<p>This is a nagging issue with NOOBS on the Pi. Best method I have found: hook up your composite screen as the only display (no HDMI) plug in the Pi and hold down the shift key until the green light stops flickering, then press 1, 2, 3 and 4, wait after each press to see if the display comes up. Composite screens should be either 3 or 4 . Which ever one works, that is what you want to set sdtv_mode= to. 1 and 2 are both HDMI displays, 3 and 4 are PAL and NTSC composite displays.</p>
<p>Hey there, im the same user as 'RayV3' and I got the screen to work while in recovery mode on both 3 and 4. My only problem now is that I cannot get the settings to stay after rebooting. The best I have gotten is that after it finally seemed to stay, the screen flickered in and out. any possible ideas? IM SO CLOSE I CAN ALMOST TASTE IT</p>
<p>Oh no! This is my fault. I gave bad advice. I was having the exact same problem on a recentn project when I realised that I had conflated input selection on startup (when you press 1-4 to see the menu) with the sdtv_mode setting setting (1-4). They are not the same. Turns out sdtv_mode is actually a choice of which composite video mode you want, so even if you hit 3 on startup for composite video, you want that setting to be 1 or 2 for PAL or NTSC. I had the same issue as you with it set to 3, turns out that's Brazillian PAL and it almost sorta works (flickers liken that), but when I set it to 2 it worked well for me. My apologies. Hope that all made sense, just rolled out of bed.</p>
