Re: Raspberry Pi 3B+ Unable to sync to correct time

It looks like a DNS problem. The output from timedatectl shows not synced. No return from the google.com ping. All symptoms of DNS not working correctly. You might post the last 15 or so lines of /etc/dhcpcd.conf if you are using a static IP. If you are using dhcp then: cat /var/run/dnsmasq/resolv....

Re: Setup wireless adapter with Rpi 3 b+

One way is to check your router's active associated MAC addresses vs. MAC addresses assigned to your interfaces.
Assuming nothing is connected to the ethernet port, if you disable the onboard wifi (per above) then your USB adapter is the point of WIFI connection.

I had a go at adding the new AWB 'greyworld' parameter to Pikrellcam for V2 NoIR cameras (see sticky at top of camera forum by jamesh). It's rather trivial :) As of this writing, you will need to run rpi-update to get the newest firmware. That will change soon, I assume. In ~/pikrellcam/src/config.c...

Re: Anyone in the US need an official Pi4 UK power supply?

Thanks for the suggestion. I considered that, but I'm rather anal (can I say that?) about reliable power. It would cost about $8 to get an adapter I would be comfy with.
Should I be so lucky to get my hands on a 4B4GB I'll buy a US version (locally :D ) for about the same price.
So the offer stands.

I've been dealing with a similar (if not identical) issue with 4kp60. My monitor is a Samsung U28E590. Samsung says HDMI2 can push 4kp60. I could not get 4kp60 from either my Pi42M (config.txt was correct) or my Windows 10 desktop, regardless of HDMI port. I switched my Win10 box to 2560x1440 @ 60Hz...
