Re: Use Wifi in latest raspbian lite stretch in headless mode

Sigh.

Why?!!? Stretch now requires the ctrl_interface line, whereas Jessie allowed you to omit it - see ...

Re: PiServer - Client OS installing error using apt

The PC running PiServer needs internet access - at least for first setup.

Try typing that command in the terminal:

Oddly that blog announcement doesn't mention what should be the MAIN point :

Zero WH is available without the 1 per customer restriction ?

( the pi hut and modmypi pages now don't mention any restriction for the WH version
and previously modmypi was selling up to 20 qty of Zeroes with header)

Many usb devices will still continue to work at 3.3v

From experience I've used pi zeros with usb wifi dongles running at 3.3v with no problems.

Can anyone name any other product where there's such an 'insane pricing scheme', where purchase cost increases the more one buys ?

The Pi's need to be connected at a particular point in the setup so that the PiServer can see them on the network, in order to set them up.

A pi zero (or original B) isn't too fussy on power - it'll work fine with 4v-5v and 200mA which covers any "bad" Usb cables. You really can stick it on any USB and expect it to work e.g TV Usb sockets, or a PC hub A point to make is low voltage won't damage anything but high voltage will... The pi3 ...

You can emulate x86 using qEMU and run windows 95 but it's not exactly fast - maybe usable for some things.

XP was unusably slow when I tried.

Try finding a Linux alternative to whatever you are trying to run.
