Win11 installation

Took me some time (weeks, months ?) to figure out how to install Win11 on my ASRock A520M-HVS motherboard. Not so easz, maybe because I have become afraid of the requirements. I have two very old displays (DELL and LG ) but they fit nicely on my desk. I like it to be able to work with two displays.

Even copilot pessimist about using so old displays, or should I say graphics card (NVS300). Well Gemini gave me hope telling that A520M-HVS motherboard can manage two displays. And thats true. I got rid of my NVS300 and connected the two displays dot the HDMI and VGA port.

Getting the motherboard configured for Secure boot was quite tough. You cannot do it in “one stroke”. Each time You change the motherboard configuration setting You have to save the new settings and make a reboot.

SATA connectivity also played some tricks. Windows11 would not install being connected to SATA2. It must be the SATA1 connector on the motherboard.

That s all.

ChatGPT mistaken

Definitely wrong what ChatGPT claims : “Even though your admin user is a superuser in Django terms, the web interface does not currently have a menu for creating new users. The Paperless-ngx UI is mainly for managing documents, tags, and organizations — user management is done via the command line.”

ChatGPT even states “

Ah, that makes sense 👍 — the older 32-bit LinuxServer.io image (or maybe the official Paperless-ngx 32-bit variant) had a slightly different web UI that did include a “Create User” option.

The 64-bit / latest LSIO image you’re now using has removed that option — probably to simplify the web UI and encourage using the manage CLI commands for user management.

So even though it looks different, it’s not a bug — it’s just a change in the UI between versions.”

Definitely not true.

I do have a menu for this in my Paperless-ngx installation, no problem creating a new user.

I cannot say for sure (though tried it). I believe that Postgre as a database is not a condition for a flawlessly running Paperless-ngx installation. As far as I know today Paperless-ngx can be fully functional with NoSQL and MariaDB.

Docker 32bit, paperless-ngx and ARM processor (Raspberry)

This is toxic. Definitely not working, besides Raspberry OS is 64 bit. Paperless-ngx instance always crashes using arm32v7 image. I did have a working Paperless-ngx instance based on a docker 64bit installation. But another Raspberry 4, Paperless-ngx crashing all the time

Otro mensaje de error que no deja adviniar lo que hay que hacer. Tengo que traducir : Hasta mañana. Yo muy preocupado. Queria hacer una demanda online, porque las citas con la INEM dificil conseguir. No fue posible en este momento. Muy contento cuando el día siguiente todo ha funcionado bien.

Porque muy cierto que mis credenciales, es decir el CIP de mi tarjeta sanitaria son correctas. Este mensaje de error no explica bien porque el proceso de autenticación ha fallado. Pues bien, he encontrado la solución : El usuario conectado a esta maquina (yo) no ha hecho la instalación del certificado idCat.

Raspberry 4 case with TFT 3.5 ” Display

Whoever fights against progress and does not want to use a Raspi 5, Raspi 4 still working with the latest OS (Raspbian GNU/Linux 12 (bookworm)) and I do have a case with 3.5 ” display which is working (Though could not get it to work as a second display along with my HDMI based monitor).

Basic data for this display :

Item	Property
LCD Type	TFT
Interface	SPI
Touch Screen Controller	XPT2046
Colors	65536
Resolution	320×480

Driver installation :
rm -rf LCD-show git clone https://github.com/goodtft/LCD-show.git chmod -R 755 LCD-show cd LCD-show/ ./MHS35-show

TFT 3.5 working config (TFT 3.5 only!) :

dtparam=spi=on
dtparam=i2c_arm=on
enable_uart=1

dtparam=audio=on

display_auto_detect=1
auto_initramfs=1
max_framebuffers=2
disable_fw_kms_setup=1

Troubles with PS2

My new motherboard has a PS2 connector and I still have a PS2 Logitech keyboard working fine, so why not using it. Quite worried because sometimes it stopped working. Did not understand what s the matter. Plugging in and off, sometimes it did help, sometimes not.

I have some spare PS2 keyboards, so I wanted to find out if there s something odd with this keyboard.

Then I did rmember that some time ago I did have some issues with the PS2 extension cable. And in fact, the reason for this miship, a pin inside the connector has not been straight any more. Put it up straight could fix this issue

Gemini : Disappointed

Easy question : How to configure second display using Raspberry Raspian OS ? Asking Gemini : Answer : <ctrl94>search_results {“answer”: “I am sorry, but I cannot provide an answer to this question. The search results are from 2021 and 2023, and may not be relevant to the current date. For the most up-to-date information, I recommend searching for the latest guides and tutorials on configuring a second display with Raspberry Pi OS.”, “query_sources”: {“original_query”: “Raspberry Pi OS second display configuration”, “sources”: []}}

Tried it with ChatGPT : I get a valid response with perfectly formated instructions.

Meanwhile got aware that Gemini is quite ignorant if compared to ChatGPT. For instance when installing Paperless-ngx Gemini does not know that this document management system is not compatible with MySQL style databases and that I have to use Postgres,

Gemini is also rather greedy. After some questions stops responding. ChatGPT is a lot more generous. Copilot as well.

0.91″ OLED I2C Display

If You have a small Arduino project, You do not always want to connect the device to the serial monitor.

There are the rather bulky LCD displays, concerning the model 2004 16 x 4 it is rather expensive.

So why not try it with an OLED display? There are two formats of OLED displays and I have tested them both.

The first one has 32 lines, the other twice as much.

I would say, You can have one line with rather big sized characters if You use the 128×32 OLED.

So You are better off with the 128×64 OLED because with smaller characters You can display up to four rows and You do not need the serial monitor.

Lidl Silvercrest WiFi SWV 733 A2 repeater

You want to connect a PC, Laptop, SmartTV whatever to the network. You do not want or You cannot use Ethernet cable connectivity. So You think You can choose this option and use the Lidl Silvercrest repeater.

What is the setup ? You have to configure it in client mode. When asking about an IP adress (LAN interface setup), it does not matter. This is just for to be able to access the repeater. For DHCP, configure it with “Server”.

You have to configure the wireless connectivity with Your credentials for to connect it to the router. of course. The Wireless Info box should show the status “connected”.
