AQE meetup - 21 Nov, 2012

[Damon Rand]

Hi everyone,

A group of 12 of us meet at Watershed last night to build our air quality eggs.

1. Building the eggs

This turned out to be pretty easy, the three sensors just slotted in,
we powered the boards and done. One issue was that fans didn't arrive
so I will need to get these sent over. No one undertook the challenge
to build perspex enclosures on the night so its yet to be seen how
tricky that ends up being.


2. Programming the eggs

Our first activity was working out where to get firmware to load onto
the eggs. With help from Dirk at Wicked Devices (egg manufacturers) we
arrived at this list..

Base -> https://github.com/jmsaavedra/Air-Quality-Egg/tree/master/AQEBase
Remote -> https://github.com/jmsaavedra/Air-Quality-Egg/tree/master/AQERemote
Remote shield -> https://github.com/WickedDevice/aqe_sensor_interface_shield

We have so far been unable to program the remote shield firmware as it
requires an AVR ISP Mk II programmer for the 2x3 connector which we
didn't have on hand. The readings will be available but not as
accurate as with latest firmware.

Addendum. It now appears that at least AQERemote may not be correct so
I will need to check this..


3. Connecting the eggs

We got sensible messages from a cable connected to the Base egg.

And sensible temperature reads coming from the Remote egg.

===

But there is a probelm with the data going into AQE.com/Cosm. I've got
in touch with the design team about this problem..

===
Sending data to Cosm
Data sent
Too Long Since Last Response From Cosm, Resetting

So some more work to do but we are getting there!

Hi Damon / All

is there another date for a build workshop? I'd really like to get my egg up and running :)

cheers
