Re: Powering my RPi projects using buck converters

@LTolledo, what power supplies do you use when using those buck converters? Are they all 12V? I currently use laptop chargers as power supply and did not have problems with them, they are powered on 24/7. (19V -> buck converter -> 5.2V)

Hello, I have a Pi3 B+ on which I have installed the 2020-05-27-raspios-buster-full-armhf image onto a USB SSD (no SD card).

Re: USB issues with storage device attached

In my case, plugging a cheap jmicron USB 3.0 sata enclosure to a usb 3.0 port disrupts the usb wifi connection. It has good signal but no data flow. Solution is to just use usb 2.0 for the meantime.

Re: install python packages via apt or pip?

I prefer installing python packages via pip as they are newer than of the apt package versions. But they are not installed systemwide, as far as I know the current user will benefit from the pip installs.

Re: Pihole & NGINX server with Pi 1?

Pi-hole installs lighttpd by default, unless you disabled the installation of web interface. You may wan to just use lighttpd instead of nginx.
Pi 1 can handle pihole and nginx but add some tweaks to reduce memory usage of those programs.

Re: Pi 3 as wiireless client and wireless AP?

Hostapd fails with failed to connect to kernel driver That's perfectly normal. AP+STA is not supported and barely works. Get an additional adapter, or waste your time. Does the Pi 4 also has this problem? Can't connect another adapter, already using all of the ports. (usb hub is not an option ATM).
