Introduction: Raspberry Pi All-In-One With Touchscreen!

Picture of Raspberry Pi All-In-One With Touchscreen!

After my previous project, a laptop computer based on a Raspberry Pi 2, which is this : , I decided that the build was not cutting it for my daily purposes. And as I do not own a tablet or a laptop(I always use either Daddy's laptop or my desktop, I'm only 12, meh), I decided to get creative and got myself an Official Raspberry Pi touchscreen in all its glory from Amazon US, and decided that the next version of the project was gonna be A WHOLE LOT BETTER. So here it is, folks.. And don't forget to 'heart!' this build! It really makes my day!

Step 1: Parts List

Picture of Parts List

This project does require a bit of time to do, and the total budget will be in the ballpark of around 95-120 USD depending on which part of the world you live in, and the full part list is given below.

1x Raspberry Pi (variant of your choice but the Model A and B don't work yet, will work in the near future)

1x Official Raspberry Pi Touchscreen (the one that uses the DSI port on the Pi)

1x Wi-Fi dongle (probably you would want to go with the Edimax EW-7811 because its one good dongle, and seems to have great range, I was being a cheapskate and went with a generic MediaTek MT7601 because the driver is supported in Raspbian Jessie now, so why not save money when you can?) :/

1x 5200 mAh power bank (y'know, those phone chargers that put out 5 volts through a USB port? Conditions will be mentioned later.....)

1x a suitable frame to stuff it all in (Again, I re-used a cheapo 50$ Android netbook display frame)

1x Tablet Keyboard (the ones for 7" tablets that double up as cases and keyboards, and have a USB keyboard..)

1x Micro USB Female to USB Type -A Male adapter( the ones you use to connect an OTG USB drive to your desktop or laptop)

1x Bluetooth dongle (This is optional, but the more, the merrier!)

1x Small Slide Switch(to serve as our power switch and note that this should be able to handle 5 Volts at 2 to 3 Amps. Even though the power use is much lower, it is better safe than sorry), right guys? ;)

1x MicroSD card( Class 10, 4GB minimum). I used a UHS-1 16GB card from Strontium.

An afternoon of time

A bit of patience..

I guess that is it.. Now let's get on with the build!

Step 2: Assembly of the Display Unit and Fixing the Pi

This step has a lot of tutorials online. I included what I thought was the most clearly explained, and easy to follow tutorial. I would like to thank Alex Eames for this FANTASTIC demo. But I did make a small change: I mounted the Pi on its belly( USB ports facing downwards) to save on thickness. You'll understand if you look at the above picture. Anyways, next, plug the Wi-Fi and Bluetooth dongles into the bottom-most ports on the Pi which will be facing downwards. Next, cut into the back of the display frame in such a way that there is roughly a half inch of clearance from the mounts on the display( note when I say display. I mean not the Pi mounting holes, but the other mounts which are more spaced out). Next, align the display inside such that there is a straight line and no haphazard criss-crosses. The display has to sit flush with the frame and you might have to make modifications as you go. In my case I had to saw off the speaker surrounds and the camera surrounds inside the frame to make it sit flush. Anyways, on to the next step!

Step 3: Glue Time...! ;)

As you might have observed in the last step I have hot glued the batteries and the Power Bank circuit board to the display's backside. Do the same as well and we're on with the next step, wiring!

Step 4: Wiring the Pi and the Display to Power

Now, let's get on with the wiring. I've attached a wiring diagram for you guys to follow. Please make sure to follow the diagrams exactly the way they are. I chose those pins SPECIFICALLY because they are at a point where they will not obstruct airflow to the processor, keeping things cool. Also, the 5v output to the DSI display is to be connected to the GPIO pin inputs on the display controller board. At this point you might consider the fact that you could give protection to the Pi. In my case I have some electrical tape and a broken cassette case's backing to protect it. You might want to solder the wires directly, but keep in mind that doing so will void the warranty on both the Pi and the display. I used some right angled jumper wires( Female to Female) but you could engineer a Frankenstein cable by using pliers.And make sure you insulate them well.

Step 5: Connect Up!

Using the Female Micro USB to Male USB Type A connector, connect the Tablet Keyboard to the USB port on the Pi. And if you did the assembly right, your Pi should power straight up! Enjoy your All-In-One!!

Step 6: DONE!!
