Is it possible to build a tablet




















Lots of freezing and crashing, probably due to GPU. I have seen one intractable for using a Pine64 running Android Lollipop. I might give that a try. How does the T handle Linux inngeneral. Thinking about getting one tonmanage my smart devices?

Otherwise, nice project, for an android touchscreen computer. Project, result, summary Mainly inspired by Michael K. Castor awesome PiPad project , I built a homemade tablet. The main technical difficulties are: building an enclosure strong enough to hold the board, yet light enough that it is still portable, and sending power to the electronic boards it takes lots of soldering.

The final product looks like this: Top view Side view Inside What does it look like inside? Things are packed tightly Which part is which?

How do you do it? You have to solve four different problems: Making the hardware work that's the easy bit Carry electric power to the different boards trickier Making an enclosure trickier Making sure everything fits inside the box The hardware The electronic hardware itself is the easiest part: connect the screen to the video converter, plug the video converter into the HDMI port of the Raspberry Pi, connect the input from the touchscreen to a USB port, and you're set.

Now, the real problem is to send electricity to the different parts. Carrying electricity To power the tablet, you need an external battery. And you need to transport electricity from the battery to a power button, and from the power button to the different boards: the Pi itself, the video converter and the USB hub.

Same for powering the board, except it's a micro-USB plug get your best magnifying glass To power the video converter, I had to solder directly onto the board, under it. By the way, I made a mistake, and the wires should be reversed.

Once you're done, you connect all these to your power button: to power the USB hub, I just cut its original cable Now, all should be working together, and you can check by booting the Pi. The enclosure There are several methods to build the enclosure: Michael K. Harrison Holbrook used a 3D printer. I only had access to a laser cutter, so I used that. I cut three layers in a plate of 8mm of plexiglas, giving a total height of 2.

It is slightly larger in diameter for the bottom two layers, because the sensor is larger at the bottom. All layers are available as Adobe Illustrator files. First, I glued the bottom two layers together. Then, I added the boards. The beams in the bottom layer make sure everything stays in place without having to use scotch. You have to drill a few holes to let things out. I changed a few things with Michael design, because I wanted to reduce the amount of soldering not my area of expertise.

So the audio out blue square goes directly out of the enclosure. That means I had to remove the RCA out yellow square next to it, visible in earlier pictures because you can't have two holes next to each other. If you're not sold on the iPad and are tired of waiting for tablets from other PC makers to show up, try getting your hands dirty with a tablet you can build on your own.

The DIY tablet targets developers who want to create a tablet of their dreams or write specialized software applications. The tablet kit contains a 4. But users can also run the Android operating system on it, says Huynh. Since Apple iPad's debut in April, tablets' popularity has surged.
