Diskio Pi - The Ultimate Open Source Tablet.
Diskio Pi revisited ! New design, new fonctionnalities, new price. Diskio Pi is a kit tablet based on Raspberry Pi or Odroid nano PC.
This project will only be funded if it reaches its goal by Thu, December 13 2018 11:40 PM UTC +00:00.
Assemble the elements in 2 hours, choose your nano computer and place it in the machine. Diskio Pi is the most versatile touch device on the market.
- Compatible with nano PCs up to 4Gb RAM
- Can be used as an external touchscreen
- Up to 13 hours of battery life with the battery option
- Full hackable and upgradable
Diskio Pi is the ideal open solution that can serve as extra computer, learning code machine, or media center, to control your home automation, but also Diskio Pi can serve as living room tablet or to equip your vehicle.
Diskio Pi is for makers and professional makers who require a large touch display.
Diskio Pi is a machine with modular and fully hackable hardware. Each element is replaceable identically, and can be upgraded to new features with additional boards.
Each copy will be unique, because YOU are the maker of your OWN tablet. We just provide the material to make it.
Diskio Pi is also the ultime machine to create your retro gaming console, with or without batteries.
- All-in-one case for SBC (Small Board Computer) with integrated stereo audio and touch interface, with possibility of a battery equipment.
- Touchscreen with external HDMI and USB input ports.
- OSD settings and screen On/Off button
The OSD board is reversible, if you want to access the buttons in front of the device. The frame is designed with drilling guides.
- Compatible with the official Raspberry Pi camera (V2, 8MP), front or back position.
- High definition IPS screen with 10 points touch glass
Each element has been designed to build your own tablet according to your desires, with an effective adaptation of your SBC card.
Here is an example of configuration with a Odroid C2, 3 battery packs and the cooling solution, driven by the daughter board (board on the left).
We have designed the slimest device as possible. According to the angle of vision, the thikness is no longer a problem.
With the 3 positions switch, you can use the device with an external HDMI source without removing your internal SBC.
Of course, the touch glass can be used with the external source, via the internal USB 2.0 hub.
We have thought out this machine like a tower PC, with a tablet format.
The SBC board is fixed on a plate, which is clipped into the tablet. Many different cables will ensure the compatibility of about ten types of boards.
Here are the main ones:
The basic kit contains all the parts to build your tablet, powered by cable.
- Screen and flat cable x 1
- Touch glass with USB controler board x 1
- ABS case x 1 (without the stand)
- Racks plates & nylon spacers x 2
- Daughter board x 1
- Video controller board with OSD board and cable x 1
- Ethernet & sound jack board (L board) x 1
- Internal cables for : Raspberry Pi (1, 2, 3 B/B+ and Zero W, WH), Odroid C1+, C2, including Ethernet & HDMI internals cables.
- Internal ribbon cable & connector for external HDMI input x 1
- AC/DC power adaptor with EU, UK or US cable x 1
- Screws and a small screwdriver x 1 set
- Assembly instructions x 1
Using the internal USB HUB, you can plug a mouse, a keyboard, a large dongle... If you're using another board than Raspberry Zero, one native USB port is free to plug a flash drive.
In the case of internal GPIO access, a flat cable will be proposed in the Diskio Pi store. Note that this access can't be installed with the VESA option.
Update for the V1.0: without price change, an USB port will be added to power any compatible external board. This port will only be activated in the screen mode.
2nd Update for the V1.0: to anticipate a future audio output, a connector will be present on the Lan board, without extra charge. The internal audio cable will be sold separatly on the Diskio Pi website.
The basic version is the best choice for any DIY home automation installation. Encase the device in a wall, and only 12mm thikness is visible. Safe and discreet, as you need.
Given some fragile and small parts, the assembly must be done by an adult, or a child over 12 accompanied by an adult.
The general concept of the Diskio Pi project is to propose as many options as possible. Some are available now, others will be available only if the funding reaches a threshold.
Here's how the options are established.
- The 4 cells battery option, with the charge / decharge / balance / jauge board.
These LiPo batteries will allow to make work the screen up to 9 hours, and the entire tablet with a Raspberry Pi 3 up to 7 hours.
- The 6 cells battery option, with the charge / decharge / balance / jauge board.
Enjoy your tablet during 10 hours without recharging !
To help you to choose the battery you need, here is the life tests results according to 3 different SBC:
With the stand, it's possible to use the tablet from two different angles. The reverse position is almost essential to read book with the machine on the knees, or to follow a cooking recipe !
No tool is required to install or remove the stand. It is operational in two seconds. We also designed an integrated handle for a transportable use.
The cooler is composed of a heatsink (25x25) with thermical pad, a fan, and the temperature sensor. You have just to place the cooler on the SoC and plug it at the daugther board.
The cooler is recommanded if you want to use Diskio Pi with any Odroid board, or with the Raspberry Pi 3 B+.
The VESA plate is compatible 75x75. This option is necessary for specifics configurations and uses. At work, for a public use... Or just to adapt your own VESA stand.
Add a 2'5 HDD or SSD in your tablet.
Other options, like POE support, double SD card reader with external swich, or other specials boards will be also available in the future.
The external display function is compatible HDMI version 1.4
In the case you would like to adapt the UP Board, the original equipment UP fan is required.

Risks and challenges
The ambition of the Diskio Pi project is to imagine a new way to take advantage of our digital datas, while having the greatest possible hardware flexibility.
In addition, the ecological aspect will be soon the strong point of our proposition, because we must exploit our end of life devices in a better way than today.
Our needs for rare earth are growing, and we must save natural resources. To do this, replacing what is necessary seems essential, in addition to recycling.
We want to taking the lead proposing a new electronic consumption mode, more responsible and more respectful of the nature.Learn about accountability on Kickstarter
