Re: Pi 4 with 10' power cable

I'd simply use a 120v extension cord and plug the power supply into it as suggested previously.

I agree with using a pad when there is a noticeable gap.

You might want to check the raspberry pi usb hub compatibility list before buying a hub.

RealVNC-server arm64 is working now.

The way things are going, the beta will be over soon.
I installed tightvncserver and xtightvncviewer. They appear to be working fine. Using the file command I see: ELF 64-bit LSB pie executable, ARM aarch64.

Re: new Raspi4 - won't boot... with sd card green lights, then go out.

I would put Raspberry Pi OS onto a new micro SD card using Raspberry Pi mager and copy a file called ssh to it to enable ssh. Then put that card into pi4 and power on. That will only work if you have an ethernet cable connected, otherwise you will need a valid wpa_supplicant.conf file on the SD car...

Re: RPi4 doesn't boot when devices attached

When you say nothing happened do you mean the RPi 4 did not boot? In the past there have been problems with some USB-C power supplies not working with the RPi 4.

Re: Yesterday, another 3 Pi4Bs 2GB died within 2 hours. Now it's 5 out of 20 dead.

So here's a wacky idea: counterfeit? Yes, that is wacky. Firstly it's pretty much impossible to by the Broadcom SoC used on the Raspberry Pi. Secondly, even if one could I very much doubt anyone could make Pi clones using them cheaper than they are already. There would be no profit in it. Of course...

Re: Yesterday, another 3 Pi4Bs 2GB died within 2 hours. Now it's 5 out of 20 dead.

I've just looked at the PCB of one of my 4GB RPi 4's and it's clean. I notice that the silk screen of TP3 and TP23 are messy. I've examined a couple of other Pi's as well and the silk screening on them is perfect as well. So here's a wacky idea: counterfeit?

Re: My pi3 keeps getting corrupted

Are you reusing the same SD card after each corruption? If so, try a different SD card. I use the SD card copier to backup my SD cards, and rsync to backup my hard drives. I've never experienced corruption even after power is lost. I've certainly had raspberry Pi's lock up and couldn't ssh into them...

Typically the temperature ranges from 29'C at idle to 40'C with all cores at 100% for short periods of time. I did a 10 minute test with all cores @ 100% and...
