Re: 1 big PSU for multiple Pi's?

you could mount those on one of these stacked.jpg for the PSU, I'd recommend you add the individual RPi's recommended power requirements (in watts), then add the power requirements for the peripherals to be connected to each RPi (again in watts) after getting the total multiply it by 25% (to give so...

Re: Can't change permissions on external drive

how is the external drive formatted? NTFS? FAT32? EXT4?

I usually mount my external drives either as /media/pi/USBHDD or /mnt/USBHDD and got permission setting problems with FAT32 formatted drives.

also its usually better to do permission change as root, not via sudo

Re: want to watch videos from laptop folder on pi/kodi/tv

on your win10pc did you share the video folder?
did you set permissions and access rights to the folder?
is the win10 pc connected to the network?
is the RPi connected to the network?
is the win10 pc powered on when you try to access the shared folder?
is there anything else you're not telling us?
