At Omni we're using TP-Link dual-band home routers (N750) and modifying
them for PoE.
These routers have gigabit ethernet.
Unfortunately gigabit ethernet and PoE at the same requires special
ethernet transformers and these routers don't have that type of transformer.
This means that they drop to 100 mbit when we modify them for PoE (but only
on the port we modify).
I was looking into how to get around this problem.
I thought maybe there was a way to do gigabit half-duplex on two or three
…
[View More]pairs, but it seems like that's not possible.
BUT! It looks like TP-Link makes a PoE splitter which can apparently handle
gigabit:
The TL-POE10R
Here it is for $12:

I ordered one so we can try it out. If it works we should just do that to
all of the routers. No reason not to have gigabit if it's only $12 extra
per router. It's still only $77 total for router + PoE splitter.
oh and btw, someone is selling dirt cheap Ubiquiti Unifi UAP devices:

Caution: They are 2.4 GHz only.
I ordered one for the mesh, just so we have it to test our firmware on.

Have you folks seen the Tessel 2.0?
substack just informed me that the new one is no longer using the weird lua
node thing.
Instead it's actually wifi router hardware running OpenWRT with an ARM
build of node.js
We should pre-order one and build think about making a simple node.js sudo
mesh module that makes it super easy to run a node.js app on the mesh from
a tessel device
It would be pretty easy to make it possible to do:
npm install -g pplsopen
# configure peoplesopen.net adhoc wifi, …
[View More]grab static IP from
meshnode-database and set up babel
pplsopen wifi enable
# same but on ethernet
pplsopen ethernet enable
Definitely a side-project, but could be pretty easy depending on how
standard their OpenWRT install is.

Just a reminder that tonight is our weekly mesh hacknight!
I'll be there, caffeinated and hopefully finalizing the extender-node
system!
We still need someone to finalize our new web UI and package it as a
sudowrt package, if anyone wants to take this on!
