revisit RPI PINN

now with a bigger drive on a RPI3
( USB3 UGREEN with TEAM 120GB SSD on USB2 of RPI3 )
what is little bit faster as my uSD
i think about how to used that space better?
+ while we set it up as file storage
+ + SAMBA server
+ + docker nextcloud ( web file server )
it can be useful,
BUT this is about learning and not production use...

try FydeOS

after win10 on old desktop now use
Ubuntu 25.04 x86_64
BLOG Ubuntu

and also on old laptop upgrade to
BLOG KDE Plasma Neon

i now want play on that laptop ( what i not use much ) with
FydeOS
after check some YouTube videos, like from EC

no idea if that ever works out? a PS CV CC wifi adjustable current

you know Power supply? like for USB 5VDC...
have a constant ( controlled ) Output Voltage.
But there are also "bench" "lab" power supply what have a adjustable Voltage
but for some usage you need a constant current 'CC' ( with a variable Voltage )
like LED driver and battery charger...
then it would ( automatically ) have a CV mode and a CC mode, depending on the load and CV, CC adjustments.
in that case that current could be also adjustable, like by a POTI
