RadioSottoTerra!! Italian Caving Podcast


It's online my new SottoTerra! podcast: A podcast for the caving community!

Here a step by step guide on how I got it working.

Method 1: Using 2 monitors (tested):
       2 monitors
       1 VGA cable
       1 DVI Cable
       EVGA Nvidia GTX 1050 GPU
       EVGA DVD-rom GTX 1050 driver disk (it comes with the newGPU)
       PC with H-CUPERTINO2-H61-uA TX mother board (HP Pavilion P6-2119EL )
       Bios Version: AMI 7.14 (the 7.16 should work as well)
       OS: Windows 10

Step 1 - Install the graphic card:
       Disconnect the PC from the power
       Remove the old graphic card
       Insert the new GTX 1050

Step 2 - Connect the 2 monitors:
      Connect* the one monitor with the VGA cable to the integrated graphic INTEL HD.
      *Note: in the bacj of my tower pc the VGA plug to the integrated graphic was covered with a piece of plastic with the label "Do not remove". Obviously you do have to remove that...
      Connect the second monitor with the DVI cable to the GTX 1050
      Reconnect the PC to the power 

Step 3 - Bios Settings (this step might be unnecessary)
      Switch on the PC
      Enter in the Bios (on my PC you have to press Esc and then F10)
      Go to Bios menu: Advanced > PCI VGA Configuration
      Set "Intel VGA controller" as primary VGA device (NO the Nvidia)
      Save the settings and reboot

Step 4 - Install the EVGA GTX 1050 drivers
      At that point Windows 10 should start
      You will notice that only the monitor connected to the integrated VGA is working
      Insert the EVGA GTX 1050 DVD and start the graphic driver installation
      After a lot of time, during the installation progress, the second monitor (the DVI - GTX 1050 one) will become alive!
      Wait until the driver installation is completed
      Power off the PC

Step 5 - unplug the VGA monitor
       At that point you can unplug the VGA monitor connected to the integrated graphic
       Switch the PC on, with the DVI monitor connected to the GTX 1050

Step 6 - Enjoy your new GTX 1050
       Enjoy your brand new graphic card fully working!!!!

I do not have an official benchmark number, and I don't even know how to get one....
But, the Train Simulator (that what the reason of the whole operation) was working @ 15-20 frmes per seconds with the old card, it's now working @ 60-80 fps!!! 

Final Notes:
1 - The method should work using one monitor only (but I didn't test that obviously:
        a - Connect it to the VGA integrated
        b - Install the EVGA 1050 driver
        c - Restart the PC with the monitor connected to the DVI - GTX 1050

2 - The method should work with the Bios v 1.16 as well since the change log reports only minor changes; YOU DON'T NEED THE BIOS V 8.XX (even because it is not available)

3 - The Bios settings change might be not necessary


Are you looking how to get a real experience of flight with your PC? Here you will find the solution!

What you need:

1 - X-plane (I have a v9 lincensed)
2 - Google cardboard or similar (I have a Durovis Dive) -
3 - A smartphone running Android (I have Motorola Moto X)
4 - App android "Trinus Gyre" -
5 - PC software "Trinus Gyre Sever -
6 - X-Plane plugin: "Pilot View" -
7 - A PC running Windows

Setting UP:

1 - As first you need to connect your smartphone to your PC using the USB Cable.
2 - Start the Trinus Gyre App on your smartphone and the Trinus Gyre server on your PC. Here the setup for the server:
     a - uncheck the "Autodetect" option
     b - select the "USB Tether" option
     c - put the same IP that you see on the Trinus Gyre APP on the smartphone
     d - select again the "autodetect" mode
     e - select "Windows Mode B" in the capture mode module
     f - select "Fake 3D" in the video Setup
     g - Sensor Type: try both the "FreeTrack Mode" and the "IR Mode"; in case you are using the Free Track you must check the "Invert" flags.
     h - set a "reset" key, I used the "\" symbol

4 - Now you can start X-Plane and then connect the Trinus Gyre Server to the smartphone (click on the the power symbol in the low right corner). Select "x - Server" as application.

5 - Done!

Sometimes during the flight you must reset the center of the point of view. To do that move your head looking in front of you and use the reset key you set on the Gyre Sever (I used "\").

Enjoy your flight!

ASTER Global DEM & Surfer: create your map in few steps!

If you are looking for digital models of terrain, there is a powerful tool that can help you: USGS Global Data Explorer.
With this tool you can explore the area of your interest and, after a free account creation, it is possible to download the DEM (or DTM ) of a specified area.
Let see an example:

1 - Zoom in a region, and select an area of interest with the "Define Area" button. In this example I choose the Vesuvius volcano in Italy.

2 - Just select the "Download Data for Defined Area" button (you need a free account at this step). Now you can select the preferences on the file format.
In this example I selected the ASTER Global DEM database (30m cell), a ArcASCII format (we need a numeric DTM), a projected UTM metric coordinate system. In the field "Research" area you can choose your field of use of these data. When ok select "Submit".
In few seconds a new window with the DTM image preview and the information of  previous selected preferences will appear.

Now you can download your DTM!

3 - Once you got your DTM in ArcASCII file format, you have just to modify its header: open the file with a text editor and  modify it as follow.

Basically you will use the "cellsize" instead of "dX" and "dY". This step is necessary because Surfer cannot read the file with its original header.

4 - Open Golden Software Surfer and select "Grid"->""Convert" in the menu.

Then select as "ASC Arc/info ASCII Grid" as file type and select the modified file.

Following the convertion procedure you will get a .grd in surfer file format of your DTM.

5 - Enjoy your data with Surfer! Some example reported below. You can use these data as base for your maps or to upload it in the GPS. Remember that you are using a WGS84 - UTM datum.
