Mark,
Can't we add all the needed drivers to Chef's builder ?

Hi Daniel
You will have to use Raspbian Linux not OpenWRT as the JustBoom Amp Zero
pHAT requires drivers from Raspbian which are not available in OpenWRT
(LibreMesh)
It is still possible to setup mesh on Raspbian but will require more effort

Hi Daniel,
Your testimonies are beginning to raise concerns.
I went with the RaspPi Zero W because I can easily add an audio DAC and
2x40W amplifier <https://www.justboom.co/product/justboom-amp-zero-phat/>,
that also happen to act as a DC regulator for the RaspPi, all running from
a 3S LiPo. Then I can also monitor battery voltage using an available
analog-input.
The battery needs to last at least 9 hours, preferrably more. Using a
4000 mAh-3S, we can heathly use up to 2000 mAh before recharging. The audio
amplifier typically uses 200 mAh per day (tested, leaving 1800 mAh for the
rest).
I haven't received the RT5370-USB yet, but I have the rest of the
hardware and also 8 dBi antennas.
Honestly, I haven't even considered using routers. Should I ?

https://lists.libremesh.org/mailman/listinfo/lime-users Ok, I have ordered a four RT5370-USB adapters.
I am building a distributed wireless audio with shairport that will
operate
4 nodes outdoors, plus a laptop. It will be
running on four Rasp-Pi
Zero W,
each equipped with a audio amplifier and
Wifi-mesh through this
external
adapter. The on-board WiFi could be used as an
access-point.
So, Am I on the right track?
If the mesh your are building is very small and not very dense, this
may work, but really don't expect any performance or range miracles
from that Ralink Rt5370 1T1R USB Wifi, nor reliability... (I'm not
saying that the SDIO Broadcom on-board WiFi crap on those RaspBi boards
is any better)
Why are you so keen on using that toy hardware? Using of-the-shelf
WiFi routers is so much more convenient and even cheaper than using
those RaspPi boards + Wifi dongles... Any reason why it got to be those
boards (which neither has any fast IO interfaces to attach proper
wireless hardware, nor any decent networking capabilities itself)?
Cheers
Daniel
