  • 23:19, 7 February 2021 95.90.215.5 talk posted a new comment on X728 (I found a solution for everyone who wants to shut down the Raspberry Pi and the X728 via a Python script. - import subprocess - subprocess.call(["sudo", "/usr/local/bin/x728softsd.sh"]) so it should work.)

  • 07:04, 5 February 2021 97.113.140.29 talk posted a new comment on X728 (I installed and used an x728 hat on an RPi4 a few months ago, and it worked great. Unfortunately, I had to do a complete reinstall of the operating system on that Pi, and when I went to reinstall the x728... I can't get it to work. When I try to boot it up (by applying power from the power brick via the usb-c port on the x728), I can see the red and green lights on the RPi start to flash as they would during startup, but then it simply shuts down after about three seconds. This happens every...)

  • 09:24, 2 February 2021 210.2.53.195 talk posted a new comment on X829 (I use X829, X735 and Pi4. It has SSD 128GB and 2.5" 4TB HDD, and I connect 5V 5A SMPS power adapter to X735. When I copy large size file to 4TB HDD, Pi intermittently hang and no response, I have to do hard reset. Other experts suggestion is that maybe this problem is from insufficient power. Can I use another power supply to connect X829 and disconnect power connector between X829 and X735, is it no problem?)
  • 00:52, 2 February 2021 84.203.113.89 talk posted a new comment on P173 (Great product for anyone requiring passive cooling. One of the only passive cooling solutions with 4 point cooling pillars including the USB controller. USB controller gets hot on the pi4 so that is a major plus. Scalpel or sharp blade recommended for separating the plastic covers either side of the thermal pads. Well engineered case, fits really well. I would buy another)
