EskeRahn | Various tech stuff ……….

This blog is for my future and past info and reviews on various tech stuff….

Phones / Phablets	Compact cameras	Various tech stuff	Reviews	Resolution and Noise

Batteries and usage	PC	Code examples	Math	Other stuff

Newer reviews can be expected to be ongoing projects, with minor additions or corrections.

Note: When I rate stuff, a 10/10 does not indicate perfect in an absolute academic sense, but as in (at least) as good as could be expected at the time, minor flaws allowed. For portable devices typically limited by the size and weight. Value for money also counts. An electronic device that got a high score in 2005, most likely would seem like pure trash ten years later….

The EASY way to make a C# Windows.forms app really per monitor DPI aware

As posted in another post, many apps have problems with windows scaling.

See these screen-dumps from Windows lengthy guide that was found here

UPDATE 2020. After Windows creators update, they made things slightly more complicated, sorry…

Here is a reasonably minimalistic approach. You will often just need code like this:

    public partial class Form1 : Form {
         public Form1() {
             InitializeComponent();
             DPI_Per_Monitor.TryEnableDPIAware(this, SetUserFonts);
         }
         void SetUserFonts(float scaleFactorX, float scaleFactorY) {
            var OldFont = Font;
            Font = new Font(OldFont.FontFamily, 11f * scaleFactorX, OldFont.Style, GraphicsUnit.Pixel); 
            OldFont.Dispose();
         }
         protected override void DefWndProc(ref Message m) {
             DPI_Per_Monitor.Check_WM_DPICHANGED(SetUserFonts,m, this.Handle);
             base.DefWndProc(ref m);
         }
     }

You will need to obey a few rules, but often it can be implemented in existing code in minutes!

Automower 435X AWD, Husqvarna, review.
This Automower 435X AWD is an upgrade from my 330X, See review here.

Overall: 9/10. Hardware: Fine. Software: Improved, still unpolished!

This is both a continuation of the previous Automowers and a fundamentally different approach

Updated 2020-04-29, Some stuff are fixed with newer firmware.

2020-08-05 This review has evolved over time from an early review, with several updates, so bare with me, that things are not in a straight chronological line…

2020-09-05 Updated with new stuck-bug

Cases/shells for the Pro1, DIY experiments
There are no official case(s) for the FxTec Pro1, so I have ordered over a score of cases/shells for various phones of dimensions close the keyboard part…

Ten have arrived, nine Nov 13., and here are the preliminary results, and a flip case fitted

Add Nov 21, two more have arrived, for Huawei P20 Pro and Note 7

Add Dec 28, two more have arrived a week ago, Flip cases for Huawei P20 Pro and they are better (the above image)

Add Jan 23, a little more on a P20 Pro flip, reverting the inner part

Add Apr 1, a better shell case with strengthened corners.

Add Aug 6, a protector for the top half – disabling edge interaction

(Will update if any of the remaining ones proves a better fit)

Newer posting are in English (well sort of, bare with me, non-native…), some over five years old just a blunt copy of the texts in Danish.

Layout – and perhaps more translations (hopefully) will be improved later.

Collecting of old stuff started May 2015. Entries are generally attempted dated with original stamps, even if they are somewhat updated since, several reviews have been ongoing ‘projects’.
