diy tablet: powerful, easy-to-make, (relatively) cheap [part 1: the guts]  -  best drawing tablet with screen
Hi everyone!
This is my first structure and I'm really excited to share it with you!
Now, let's say you're on this site or app, and I think, since then, you may have at least one idea that hits you like a baseball bat and then takes up the outer edge of your cerebral cortex.
One day, when I was staring at the bound crowd on the screen, I had this situation on the train and I thought, "Hey, what if you could make your own tablet?
"Then I started searching for the guide and 'how to' on the internet and found a great guide to Michael Castel detailing how he made his own tablet using Raspberry Pi here
With flashy battery lights, carbon fiber backing and chic walnut finish, the only thing I don't like is the Raspberry Pi and the difficulty of building it.
I want something (actually a lot)
More projects that will not cost three quarters.
So I turned to Odroid U3 looking for several great communities like performance enthusiasts and similar.
Performance will be refined further next.
A few things to note are: All prices are USD unless otherwise stated. All prices and currency exchanges are until January 2, 2015, which is sufficient to illustrate the unnecessary but poignant context.
It's time to put my money in my mouth and show the numbers.
According to Techradar, I chose several benchmarks based on a series of activities that a person would do on a tablet and benchmark it with the best tablet by the end of 2014, of course, raspberry pie.
Now, as you can see, the performance of Odroid is very close to the Galaxy tab, enough to meet the needs of my daily tablet.
While it may not have the power of the iPad air 2, the total cost of the project is lower than the iPad, and you will become cool, saying that you made your own tablet, which is an annoying bragging right.
Another point I should mention is that the power consumption of Odroid u3 at 5 v is slightly higher than 1A or up to 2A, which is very good for the battery life of most power groups and tablets.
Reference: DIY tablets are basically made up of 3 main things.
A micro-computer, touch screen and battery pack.
Please note that all shipping costs are from your country of origin to Singapore, so fees may vary depending on where you live. A.

A little fun!
Some kind of crazy scientist satisfaction from Connecting Electronics, once this part is started, you should start to feel it.
This helps not to involve welding, you just need to connect one end to the other.
First, start by connecting the RTC backup battery and the SD/eMMC module to the Odroid.

5mm USB to DC cable, WiFi module and USB to USB mini cable for Odroid.

You should have 2 USB Type A cables not plugged anywhere.
Figure 5: connect these two cables to a portable power supply.
If luck is in your favor, you should see the android logo on the blackboard electronic screen within a minute.
Grinning like an idiot and jumping to the last step.
I ripped my hair off when I first made the tablet because it didn't start up and I don't know why.
Fortunately, my sanity.
Sweet hair)
The Odroid community came to the rescue.
A lot of trouble, odroid, joerg, help me with the Odroid problem.
So, in my experience, I am here to hand-write a complete trouble-shooting guide for the new one: if you still can't get your motherboard to work, Ze complete oguide guide, I suggest simply post your question on the Odroid Forum.
I am sure this amazing community will be able to clean up soon.
What good things are really cool if you don't show off?
I will post a guide soon on how to defend your new tablet! (
I'm playing with fiberglass and Pepakura method, I might switch to 3D printing if it doesn't work)
This brings us to the end of this teaching and I hope you enjoy reading or making it as much as you do.
Thank you for coming!
If you have any further questions, I would be more than happy to answer them in the comments section below! Seeya!
