Thin round T8 Mini, T8 and T8 Pro smart watch 2024 trio. Review.

Posted on by EskeRahn

The original T8 is being replaced by a new trio of a 7.5% narrower T8 Mini, a T8 and a T8 Pro with speaker and mics for BT-calls.

These are ad renderings images of the T8 Mini and Pro where I scaled the dial by 87% resp. 92% to get the actual display to case ratio(!!), and scaled them too the correct relative case size

 

Like the T8original post, this is likely to be an ongoing project for a while.

Latest updates: 2025-09-26, The 2025 T8ultra is NOT part of this trio, but a third generation.

A really THIN 6 weeks Smart watch, “T8”, (And “R18”)

Posted on by EskeRahn

(here with a loop band)

Merely 7.8mm thick (6.9 excluding small protrusion, and down to 4.0mm at the edge), AMOLED with AOD.

By far the most wearable smart watch I’d ever seen!!

ADD 20240405: I got an upcoming narrower T8 Mini. that is part of a trio replacing the original T8, see review here.

UPDATE: I have revised this thread to include the various updates from the over a year I have used it.

Currently at $25 including shipping…. Even better stamina than expected, six weeks! (less nine hours)
(This post is an ongoing project, the last change was 20240409 on 12% different weight between 1.00_24 and 1.00_23 )

Thin TN88 smartwatch, disappointed review

Posted on by EskeRahn

In December 2023 (I think) a new thin watch was launched, 9% thicker, 8% wider and with 21% larger display than the T8.

I got it 2024-02-27. The verdict is: Disappointment!

Lastest updates: 2024-03-09, back in box!, 2024-03-28 References to T8 Mini, 2024-11-12 DA09 better in all areas!

E600, E500, E400 Cheap ECG smartwatches w. breast strap

Posted on by EskeRahn

I bought this cheap E600 smart watch out of curiosity of what a breast strap mount can do.

And it is certainly better than I expected for the price, though not without its flaws!

UPDATE: The first unit is broken after just six weeks, refusing to charge!!
UPDATE II The E400 is broken with same failure, bought a E420, and adjusted a bit on that.

The EASY way to make a .Net 8.0 WinForms app per monitor DPI aware

Posted on by EskeRahn

As posted in a rather old post, many apps have problems with windows scaling.

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

With previous versions of .Net Framework this have been somewhat cumbersome, see my post here.

But with .Net 8.0 WinForms (well also 7.0 and 6.0), and Windows 11 (or newer 10), it is now fairly simple, as long as you follow a few rules, that can be relatively easy applied copying existing Framework projects. I experimented with VS 17.8 on Win 11 23H2.

Numeric facts on fractions, that few are aware of.

Posted on by EskeRahn

Assume a fraction k/m, with 0≤k≤m and look at its digits written out

  1. The fraction has a finite number of digits (less m) OR is a repeated sequence with at the most m-1 digits per group
  2. A repeated sequence will have at the most n-1 zeroes next to each other, if the number m is below 10ⁿ
  3. Interesting digit-structure of the sequence times m, with many 9’s (base minus 1) .

Cheap smart watches from AliExpress, primarily round, late 2022 and 2023

Posted on by EskeRahn

Ordered some cheap (<£40) smart watches from AliExpress in the late fall of 2022. and 2023.

First I was surprised that it was even possible to get smart watches in decent sizes, though we do not see them ‘in the west’.

Many, but not all, I bought were crap, here a collage of the crappy ones:

Xiaomi Smart Band 7 Pro vs Huawei Band 7(/6)

Posted on by EskeRahn

Xiaomi Smart Band Pro 7 has a larger display in roughly same size case and is MUCH more expensive than Huawei Band 7. Adds a few extra features, and has bad band attachment.


(updated on the inferior software and DST a week later – and again a week later after a factory reset…)

Automower 435X AWD, Husqvarna, review.

Posted on by EskeRahn

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

Initial review 2019-08-06.

Review updates:
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

2020-11-01 Updated with more elegant stop-protector

2021-04-28 Updated on serious bug during winter-storage.

Partition backup, unlocked Android phones, through Recovery.

Posted on by EskeRahn

Have you ever wanted to backup entire partitions of your Android phone?
Well it actually is quite easy for an unlocked device – Does NOT need to be rooted.
ADD: This requires the presence of a recovery boot option! E.g. from LineageOS

(The above image is ‘borrowed’ from here)

Diagonal to width, simple fractions. Different aspect ratios

Posted on by EskeRahn

Obviously it is easy to calculate the diagonal of e.g. a sensor from the width and height with Pythagoras.
And a bit more tedious the other way round using the aspect ratio. [*]
But for common aspect ratios it is even simpler, 1+1/n fractions within less than 0.4%

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

Posted on by EskeRahn

For .Net 8.0 WinForms apps go HERE (Also 7.0 and 6.0)

The below is for .Net Framework, latest being 4.8.

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);
            Refresh();
            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!

Cases/shells for the Pro1, DIY experiments

Posted on by EskeRahn

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)

Save and restore positions of windows, WindowsPosSaveNRestore

Posted on by EskeRahn

WindowsPosSaveNRestore is a tool to save the position of windows for later restore

This is primarily useful if you frequently change display configuration, say add/remove external monitor(s) e.g. by docking, or turning a device with autorotate active.

Windows also has the bug that it sometimes cram all open windows (and icons [+]) on the primary screen on sleep.

A little post on keyboard phones, and the few alternatives available

Posted on by EskeRahn

Since BlackBerry-phones are now seeming to come to a complete end (not even licensed devices), the options for keyboard phones are even more sparse.

I guess no one reading the blog is unaware that I go for the Pro1.

But in all fairness there are alternatives.

Easy inexpensive chemical free fix for smelly microfibre cloths

Posted on by EskeRahn

Microfibre cloths are nice, but get sour and smelly, even after a machine wash. (same goes for or any other plastic cloths)

They usually smell fine directly from the machine, but soon after they get wet they stink again…

This is easily fixed by a microwave oven!

Windows oddity: Schtasks.exe falsely reported error. Workaround.

Posted on by EskeRahn

If you run a command like this it works fine to any remote machine

    schtasks.exe /query /s SomePC /U MyAccount /P XXXXX

If you try to let it point back to your own machine you get an error-message

    ERROR: User credentials are not allowed on the local machine.

BUT this is actually FALSE!!! I found a workaround though..

BlackBerry Priv, Almost EIGHT days stamina, no tricks, though light usage.

Posted on by EskeRahn

I have previously contradicted the claim that the BB Priv has a poor stamina, but here an even longer run.

This is a collage to contain the almost eight days  (7d 20h), as the 3C Battery Monitor app can only show five days.
