Ich werde ja den Endruck nicht los dass dieses pi-gen ein ziemlich wüstes Gebastel ist.

Oh wow! The newly released version 1.4.0 of the Snow Macintosh emulator now even runs on a Raspberry Pi Zero 2. Previous versions only showed a black screen.
It comfortably fits into the 512 MB of available RAM, using about 50-60% of it. The downside - two CPU cores almost pegged to 100% still only result in about 1/3rd real world speed for compact 68000 Macs (emulating a Mac Classic or Mac Plus in my case). This is slow - considering how slow these machines already were.
But hey, it works!

I removed all my #Raspberrypi from my network and #NixOS configuration.
Main reason was that I needed to reduce my side projects a bit.
The raspi's were a nice experiment but I just needed to reduce my workload a bit and their hardware and architecture don't help to make things easier.
In addition I set up #Wireguard (when you remove some projects you can start new ones right?) with the plan to have it enabled all the time.
The initial idea was to have a mesh but I have now so few devices that a star made more sense.

I got my #RaspberrPi. What was the second thing, after configuring #PiHole, I did? I installed #AdaLang compiler and built Tada!
Happy hacking in Ada on #RaspberryPi!

And last but not least, Matthias Wendel has written a handy program for the #RaspberryPi PIco's programmable input/output (PIO) blocks which can turn any bit of metal into a surprisingly sensitive proximity sensor.
Yes, there *were* a lot of Raspberry Pi-based things today.

Then a new model in the M5Stack Cardputer range, but this one's not a microcontroller-powered gadget: it features the #RaspberryPi Compute Module Zero, which is basically what you get if you cut all the ports off a Raspberry Pi Zero 2 and squish it into a stamp form-factor.

Automated plane-spotting next, combining an ADS-B receiver (running via a low-cost RTL-SDR dongle) which decodes the plane's location, trains a #RaspberryPi HQ Camera Module with a telephoto lens on that spot in the sky, snaps a picture, and passes it to OpenCV to see if it actually managed to catch the plane or not.

It's #Hackster round-up time - and no, you didn't miss Friday's, I had a rare day off.
First up this week: the YARH.IO M4, a #RaspberryPi-powered 3D-printable handheld with a slick desktop stand.
If it seems familiar, it was actually unveiled two years ago - and now the design files are finally available for you to make your own.

От PLC к своему HMI и AI-анализу
В первой статье и второй статье мы заставили крутиться PMSM-мотор под управлением комплекта P-NUCLEO-IHM03, внедрив в прошивку поддержку FDCAN. Чтобы превратить DIY-проект в нечто более серьезное, нам нужен верхний уровень: наглядный интерфейс, интеграция с индустриальными стандартами и, конечно, немного магии современных LLM для диагностики. Сегодня мы построим распределенную систему управления, где OpenPLC берет на себя логику, Node-RED — визуализацию, а AI-агент — роль инженера-диагноста.

Расширяем проект на микроконтроллерах с OpenPLC
В предыдущей статье мы подключили CAN bus к STM32-IHM03, настроили базовую коммуникацию и запустили управление PMSM-двигателем. Теперь пришло время расширить проект — добавить в него периферийный микроконтроллер в качестве удалённого I/O-узла и организовать логику управления с помощью OpenPLC. В этой статье мы рассмотрим, как подключить Raspberry Pi Pico W по Modbus RTU к одноплатному компьютеру Orange Pi, запрограммировать микроконтроллер в среде OpenPLC Editor на языке контактно-релейных схем (LD) и удаленно управлять реле по Modbus. Попутно разберёмся с настройкой шилда RS485 CAN HAT, адресацией пинов и регистров.
