Welcome to the Diskio Pi Wiki.
This set of pages is the "documentation" of the Diskio Pi project, an essential tool to help you to build your own open touch terminal based on our research and development.
Diskio Pi is a DIY (or semi-DIY) fully repairable hybrid touchscreen kit device, whose the hardware can be updated with additional boards.
- Possibility to integrate single-card computers with up to 4 GB RAM
- Can be used as an external touchscreen (for a laptop, a game console...)
- Up to 13 hours of battery life with the battery option
- Full hackable, upgradable and customizable
It is possible to print the case yourself, the STL and STEP files are available on the gitlab.com website.
This wiki details the part references used, the electronic diagrams used, and all the assembly steps. The case printing guide will also be completed as the case is manufactured, and will be complete in August 2019.

The idea of the Diskio Pi came to me in 2015, with the purchase of anOrange Pi board (A20 SoC system). The novelty of the time was the possibility to install Android, something impossible on the Raspberry Pi (1) B. But the Android systems proposed (4.4) did not manage touch, I had to compile the sources myself.
The problem identified
The ambition of the Diskio Pi project is to imagine a new way to take advantage of our digital data, more opened, while having the greatest possible hardware and software flexibility.
The ecological aspect is the strong point of our proposal, because we must make better use of our equipment at the end of its life than before. Our needs for rare materials are increasing and we must preserve natural resources. To do this, replacing what is necessary seems essential, in addition to recycling.
We want to take the lead by proposing a new way of consuming electronic products, more responsible and more respectful of nature.
The proposed solution
The idea is to use existing boards (Raspberry Pi or other), and to find a way to use them in a simple and fun way with a repairable and upgradeable device.
Diskio Pi was designed like a PC, but in a portable hybrid format!
The first prototype, in 17", was big enough to insert all the boards and batteries. It was from the second prototype that a size of 13.3" was chosen. But the too thick design of this second version had to be revised, as well as its price.
The name Diskio (δισκίο) comes from modern Greek, "tablet" in English. Later, I realized that this could be interpreted as disk I/O, and it fits the project well. Although the "Diskio" brand was retained, the word "tablet" was abandoned in December 2018, as this word caused too many disappointments for the general public (size, thickness). To replace this term, the word "device" (or terminal) was adopted.
In February 2018, a crowdfunding onUlule allowed us to collect the funds to manufacture the 3rd prototype.
The difficulty to finance the mass production decided me to make some copies of version 0.3 in 3D printing, in a traditional way. The Ulule funding of January 2019 will be decisive for the future.
The V0.3.0 prototype
Here is the fully assembled V0.3.0 prototype, with the case printed by a professional method stereolithography. The modelraw, white in origin, was painted in matt black with acrylic spray paint.
The stand is removable and reversible, so it is possible to tilt the terminal into the "desktop" or "tablet" position.
Dimensions and I/O nomenclature (V0.4)
Make your Diskio Pi
- Choose your options
- Use examples
- Listing of the parts to be printed, and explanation of their function.
- Everything you need to know about printing the parts that make up the Diskio Pi case.
- Are your parts printed? Here is a guide to assemble the printed parts.
DIY and Kit version:
- The base assembly is in this section
This section details as much as possible each element of the electronics that make up the terminal. On the right, the synoptic of the daughter board, a board that organizes the entire system into a simple and compact unit.
- The electronics and the fully open source hardware:
- Mixed electronics (documented but not modifiable):
- Proprietary electronics (limited documentation):
Mounting the screen
All the explanations for the assembly of the screen and the touch glass. To be used if you print the hull yourself. (links to come)
- Place the inserts on the armature
- Fixation of the touch glass on the front frame
- The assembly of the touch armature on the screen
This version is the most popular, if you receive the kit with the pre-assembled screen.
The assembly of the internal modules
Warning: There is a (minimal) risk of destroying an electronic board due to electrostatic discharges. To prevent them, an antistatic wrist strap may be useful.
- The assembly of the on/off button
- The assembly of batteries and the gauge_card
- The OSD board
- Assembly of internal boards (daughter board, L board, screen controler)
- Place the speakers
- Place the camera
- Assembly of the pre-assembled screen
- Attach the touch screen board
- Internal cable connection
- The SBC plate
- Verifications and tests
- Closing the housing and mounting the stand
The assembly of options
Your Diskio Pi is fully assembled and the tests passed successfully? Congratulations, you can now use it! :)
Need help ?
Do you have any doubts about a specific part of the assembly ? The screen doesn't turn on ? No sound ? Don't panic! Don't panic! Theforum is here to help you.
There will always be someone to answer you !
