Using Surface Dial as throttle in Train Sim World 2

, , /

Surface Dial wheel’s direction can be mapped to any keyboard event. However, Train Sim World 2 requires the key A, D to be pressed for longer to register a change.

The solution is to use AutoHotkey to create a script which translates one key combination into a long press of A or D.

1. Create a Train Sim World 2 entry in Windows 10 Settings > Devices > Wheel (browse for the game executable located under [Steam Folder]\steamapps\common\Train Sim World 2\WindowsNoEditor\TS2Prototype\Binaries\Win64\TS2Prototype-Win64-Shipping.exe)

2. Add the mapping for an unused keyboard shortcut combination in the game (for example CTRL+ ALT + A )

3. Create an AutoHotkey Script which does the mapping from the key combination to a long press. (Install AutoHotkey and create a file train_sim_world_dial.ahk with a text editor)

^!a::
    Send, {a Down}
    Sleep, 300
    Send, {a Up}
    Return
    
^!d::
    Send, {d Down}
    Sleep, 300
    Send, {d Up}
    Return

You can now use the Surface Dial to change the throttle speed in the game.

Using Cheap China Microscope with Micro-Manager on Windows

, , /

In order for Micro-Manager to recognize my cheap china microscope, I needed to patch the provided OpenCVGrabber driver.

The original version of the driver always selected the first USB camera available, and did not pass validation of the configuration for the webcam driver from the microscope.

As Micro-Manager is Open Source, I looked into making a patch. The new version which supports camera selection from a dropdown by name. Is available for windows 10 and Version 2.0 beta of Micro-Manger:

  1. Install Version 2.0 beta
  2. Download the compiled mmgr_dal_OpenCVgrabber.dll
  3. Replace it in the folder of Micro-Manager x64 c:\Program Files\Micro-Manager-2.0beta

Status for integration into the application can be followed on the pull request.

Iceberg and IIS7 (Windows 2008)

There is a new CRM/ERP/BUSINESS web app in town and it’s free (as in beer, for 5 users): Iceberg.

There are two versions a standalone and a server install to be deployed on (MS Sql Server 2005 express & ASP.NET (IIS 5 or 6), but since I have IIS7 and windows 2008 there was some pluming needed before everything worked.

Here is what I configured in IIS 7 to make it work:

  • Set the Managed pipeline mode property of the application pool that is running iceberg to Classic
  • Under Handler Mappings add a new Script Map

    Request path: *.asmx
    Executable: %windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll

  • For the SQL connection I uncommented the string provided in the web.config file but check that the SQL server is running in SQL mixed authentication mode.
  • If there are still problems use the Event Viewer to look at the detailed error log.
