The Vivaldi tablet is a 7 inch tablet and open source KDE Plasma Active software. The €200 tablet is expected to start shipping in May, but the folks behind the official Vivaldi user forum at got their hands on an early unit — and they’ve ripped it apart to see what makes it tick.

Vivaldi tablet dissected

There aren’t any major surprises. After all, the tablet (formerly known as the Spark) is designed to be a free and open source device with an unlocked bootloader and user customizeable software.

We already know that the hardware is basically a Zenithink C71 tablet with a 1 GHz AMLogic ARM Cortex-A9 processor, Mali 400 graphics, 512MB of RAM, 4GB of storage, an 800 x 480 pixel display, 2 USB ports, an HDMI port, and a front-facing camera.

OpenTablets reports the device is fairly easy to disassemble. There are just four screws and a few plastic tabs holding the case together.

The good news is there’s some extra space which could allow a larger battery or other user modifications. I wonder if it also might be possible to add a higher resolution display. Unfortunately RAM upgrades are pretty unlikely, since the memory is attached to the system board.

Meanwhile, developer Aaron Seigo, the public face of the Vivaldi project, says that with the latest software images he’s getting around 7 hours of battery life from the Vivaldi’s 13.5 Whr battery. He says the group has also selected the hardware that will be used for an upcoming 10 inch tablet featuring KDE Plasma Active software — but he’s not sharing any more details than that yet.

  1. One of the advantages of the xrandr (to scale to higher resolution using lesser resolution hardware), is that you use far less power because you are not having to illuminate as many pixels (but it looks like you are, and testing with an HP Mini 1000 (1024×600 hardware screen) scaled up to 1280×800 (and patched to avoid the cursor jail bug), really looks very good – and at the 1024×600 screen prices vs the more expensive 1280×800 prices.

    I have not yet tried this with a Pixel Qi (7 inch or 10.1 inch 1024×600 screen) to see if it scales and still looks good.  But, for many cheaper devices this trick is worth it to try maybe (and can actually get a better device for less money) and WHEN you swap the screen, then also put in your own Gorilla Glass (that cheaper units still do not have).  

  2. Re: I wonder if it also might be possible to add a higher resolution display

    What if:
    They scaled the resolution using Xrandr (like pre previous posts) and this link (where they took 1024×600 hardware screen, up to 1280×800 scaled on the same screen):

    Being that it is a Linux OS, then why not?  Brad, have you asked them if this is possible with this device?
