time for a new PC

Budget but with little UPGRADE:

RPI4 setup for Mosquitto and Node-Red and Arduino

just tested again and want log it here

try RPI PICO 2 W

you possibly come from here
about a project:
ARDUINO IDE / PICO W / WEBSERVER / MQTT NO TLS / NodeRed trend & DB & operation / 4 Relay board /
where i also try same code on the ESP32S3

RPI: make a desktop GUI app ( QT6 C++ / Py )

while RPI is known for learn Linux and start coding
from the beginning that real
desktop app programming / GUI
comes short or, for more easy start, begins with 'PyGame' ...

and i was in exact same situation a decade ago...
in the meantime i try to stay up to date
learn / teach
* web development
* micro controller ( add web server and data handling like mqtt )

and actually lost track on what had happened on the real app development front..
but sure noticed that some things have changed
like now for RPI OS 64bit on my RPI4 use
* OS: Debian GNU/Linux 13 (trixie) aarch64
* Kernel: Linux 6.12.62+rpt-rpi-v8
* WM: labwc (Wayland)
* Theme: gtk2 [Qt]

RPI OS Linux? support default QT5? or even QT6?

big combi project with ESP32S3

sorry there was a long article here about
using ESP32S3
but it got accidentally deleted, try to feed some major points again

Arduino IDE & ACS712/758 Sensor

after test
INA219 and INA 260 sensor (I2C) here
now try a

RPI classic web-server

LAMP

Linux (Operating System), Apache (Web Server), MySQL (Database), and PHP (Programming Language)

my ADS1115 still good?

recently i had a bad day,
and play breadboard wiring with INA and ADS
and burned my finger?
assuming some boards/ measuring sensors got damaged.

try FydeOS

after win10 on old desktop now use
Ubuntu 25.04 x86_64
BLOG Ubuntu

and also on old laptop upgrade to
BLOG KDE Plasma Neon

i now want play on that laptop ( what i not use much ) with
FydeOS
after check some YouTube videos, like from EC

ESP Connect

long time not play micro controller
( and last, and still open project, was RPI PICO W )
but despite so many pending work with the BLOG 'old article transfer'
i want stay up-to-date.

RPI3 and Open Media Vault add GIT

try use RPI3 as MINI NAS
follow:

revive NODE MCU ESP32s & Arduino IDE 2

test if i could run my current big project from ESP32S3 also on a ESP32
i try on that, even after jumper the cpu temperature thing ended in kernel panic auto reboot

but i noticed that this ESP32 i have, has 2 DAC pins ( Analog OUT )
a rare feature i want use.
