Engraving handheld computers

For the past couple of years I’ve been using 7-inch handhelds from One-Netbook as my main workstation.
The devices do their job pretty well. And from an aesthetic point of view, I find these devices quite pleasing. The only thing that bothered me was a bit boring lid with no marks what so ever. Therefore I decided to put my custom logo using a laser engraving technique. The lady in the engraving is Themis (quite unusual, without a sword and with open eyes).

Sabrent Rocket NVME SSD inside One-Netbook A1

Sabrent Rocket is one of the fastest NVME SSD series in the formfactor of M.2 2242. According to the manufacturer, "its speed performance can reach up to 2500MB/s read and 2100MB/s write" (ref).
Here is what you can expect from this SSD inserted into the One-Netbook A1 handheld computer:

It’s worth mentioning that the default One-Netbook SSD shows very similar performance.

So there is no reason to replace SSD in order to get higher speed. The default SSD is pretty much the best you can achieve.

Gentoo on a One-Netbook A1

I’m glad to present you the new manual: Gentoo on a One-Netbook A1. This manual is intended to help user to configure Gentoo distribution of the GNU/Linux operating system for One-Netbook A1 handheld computer. Despite the fact that the manufacturer claims Linux support on the product description page, to my knowledge there is no Linux distribution, which actually supports the device out of the box. Therefore I hope that this manual will be useful for some A1 owners.

I would also like to note that there are several other Gentoo manuals available for different handheld computer:

Benchmarking OneGx1 Pro with eGPU

I connected EVGA GeForce GTX 1080 FOUNDERS EDITION to One-Netbook OneGx1 Pro via the following eGPU box: Sonnet eGFX Breakaway Box 550.

Here are the main results:

  1. eGPU can improve 3D performance of OneGx1 Pro by at least 4 times.
  2. Performance of the video card inserted in the desktop is significantly higher than performance of the same card connected via eGPU box.
  3. Performance of eGPU is significantly higher when the image is displayed on an external monitor.

More benchmarks of OneGx1 Pro are availavle here.
