A priori le bug est connu, mais j'ai épuisé les solution que j'ai trouvé :(

Wie gelingt der Zugriff auf #Wechselrichterdaten ganz ohne Cloud?
Wer ein #Balkonkraftwerk hat, interessiert sich sicherlich für die laufende #Energieerzeugung. Viel zu oft benötigt man dafür eine App mit #Cloudverbindung ins Internet. Für die lokalen #Datenverarbeitung im #Heimnetzwerk ist das unerwünscht. Ich konnte meinen #Wechselrichter direkt ins #WLAN hänge und die #Cloud deaktiveren.

Appena ritornati da 16 ore di downtime per @index durante le quali ho messo alla prova il nuovo #raspberrypi 5, debuggato problemi di voltaggio (d'altra parte, perché comprare alimentatori ufficali) flashato ripetutamente le microSD, dormito molto poco e configurato NFS (sqlite gestito da rasp 3 -> via NFS -> Rasp 5 -> NVMe collegato via USB... cosa può andare storto 🤣).
Ora è il momento di capire da che parte prendere #nextcloud AIO! 💪

Wanted to capture this observation and compare it over time: I recently completed a drive from Cleveland, Ohio to Albany, NY via I-90. What struck me was how poor the road surface seemed to be compared with the other times I have made the drive. It got me thinking of running an arduino or Pi with a couple of parallel accelerometers and GPS during the drive to gather data on how good/poor the road surface is at any given location. Then use this over years and see how better/worse the roads are when compared to other times. I would also think the various state DoTs in the US have data like this?
There are some variables like environmental considerations and suspension condition though I suppose those can be noted or somehow calibrated into the data.
Lastly, just watch out for potholes and deteriorating bridgedeck seams!

虚惊一场，树莓派的 USB 控制器没事
想起来树莓派有个 USB 电流限制开关，检查了设置确实自动打开了，所以另一个硬盘盒插上也不能用
只有原来的硬盘盒确实挂了

之前有想过能不能把 PD 9V 3A 降压成 5V 5A，这样就不挑充电器了
问题是这东西的价格比直接买个 5V 5A 的 PD 充电器还贵
何意味

🚀 Rock-solid Real-Time performance on Raspberry Pi 4!
Just stress-tested a custom #Buildroot (Kernel 6.12.61-v8 #PREEMPT_RT). Even with a massive memory hog running (stress-ng --vm 2 --vm-bytes 1G), the results are insane:
🔹 Avg Latency: 14µs 🔹 Max Latency: 42µs 🔹 Jitter: Virtually zero
This #RPi4 is now a deterministic beast. 🐧🛠️ 64-bit RT Linux at its best!

The new iteration of my #DIY #RaspberryPi #Linux #tablet looks great, in my opinion! Very happy with how it came out, and it feels much more comfortable to hold and use than the previous version. The back cover was designed using #FreeCAD. I added "fingers" over the screen buttons and engraved symbols into them, added air vent holes on one side with SD card access hole, and a button on the back for screen backlight brightness control.

Finally I was able to finish blog post https://pragdevnotes.com/elixir-nrf24-library/index.html about my https://gitlab.com/boskoivanisevic/nrf24 library.
Next on the agenda is post how it is used on #raspberrypi with #nerves and #arduino station.
