Eggs at Maker Faire tomorrow

[Damon Rand]

Hi everyone,

I hope you will all be coming to Bristol Mini Maker Faire tomorrow, it should be a load of fun! 

http://makerfairebristol.com/

I know its been ages since the January egg build sessions (things have been crazy busy at work) sorry about that! However, if you come to my stall at Maker Faire tomorrow you can finally pick up your egg enclosure and fan!  The day will be too busy to do any actual 'making' but if you haven't already picked up your egg then I can bring you in a prebuilt one - drop me a direct email if you want to do that..

General project update. I'm attaching photos of two eggs I have running out my window.. A month running outside and they are still both delivering data -- evidently the weatherproofing is holding up ok! The enclosure and fan makes a substantial difference to the sensible-ness of the results. The CO, temperature and humidity data is generally looking pretty good now. The NO2 sensor has given some tantalizing results a few times but its still a bit hit and miss I'm afraid, I'm hoping to get some more time to work on it soon.

My eggs are here if you want to take a look!

Hope to see you tomorrow!

Hi all,

For those of you who came to Maker Faire, I hope you enjoyed yourself. It was a fabulously well attended event, I don't know if official numbers are out yet but it felt like thousands of people made it along..

There was some discussion on the day about Austin's NO2 sensor readings which appeared to show some afternoon spikes in NO2..

Alas, it was actually a bug in the EggRemote firmware! :-)

You can tell which firmware version your egg is running by hovering over the aqe:firmware_version tag in the COSM feed. To be getting reasonable results you must be running at least aqe:firmware_version=4 on temp/humidity and aqe:firmware_version=16 on NO2/CO.

Cheers,

Damon.

Hi Damon,
Maker Faire was rammed, wasn't it. Barney from Hackspace did a timelapse showing the hordes decending!

I tried changing R0 as we discussed to try and remedy the dodgy data. But I discovered it didn't make any difference. I then saw there was new firmware and loaded v1.4 firmware on the remote node. This seems to have stabilised the data going to COSM, but may have caused another issue where the base egg only sends data back sporadically. But it could be environmental, not sure. I'm trying a few tests to figure it out.

Bottom line? I'd say try the new remote firmware / sketches but make sure you keep the old ones incase you end up with communication problems and need to revert.


Cheers

Thanks,  I see that the NO/CO firmware version information comes from the shield, so I will need to re-flash mine with the latest "aqe_sensor_interface_shield-master" software from github...

Thanks,

Alan

[Alan Senior]

OK, finally there.

Flashed the shield but then forgot that the R0 values need to be
reset, so AQERemote has then to be flashed with PollEggBus_WriteTest
sketch, this has to be run for a while to set R0. Then we need to
reflash AQERemote board back with latest AQERemote software.

NO and CO sensor telemetry now gets reported with Firmware Version 17.

So I think I now have the very latest software versions finally loaded
on my AQE and it seems to be running... Phew!

TTFN,
Alan

Hi Alan,
I updated my remote egg to v1.4 but haven't attempted updating the sensor shield
Did you flash your firmware using the load.sh script & the eggremote_atmega328.hex file?

Cheers

Toby

[Damon Rand]

Here are my notes on updating the shield firmware..

-c -> the programmer type
-p -> processor type attiny88
-U -> the file to write into flash

D:\cepro\Downloads\avrdude-5.11-Patch7610-win32\avrdude-5.11-Patch7610-win32>avrdude.exe
-cstk500 -pt88 -PCOM12 -U flash:w:aqe_sensor_interface_shield.hex

Hi Toby,

 

I used Atmel Studio 4 and this programmer:

http://www.pololu.com/catalog/product/1300

 

Studio 4 is free and connects to the programmer, it is then a case of selecting the device and choosing the file to be flashed.

 

It may be easier to follow Damons method though I have not tried it myself.

 

The software to flash is the  " aqe_sensor_interface_shield.hex" file.

 

I then found the Egg reported 0 for NO and CO so had to the reset the R0 values, so AQERemote has then to be flashed with PollEggBus_WriteTest sketch, this has to be run for a while to set R0. Then we need to reflash AQERemote board back with latest AQERemote software.

 

Sadly my egg seems to be generating bad values even with all the software updates.

 

My feed is:

https://cosm.com/feeds/87422

 

I also seem to have fallen foul of another software bug as my Egg reported a serial number (MAC address) with the top 4 bits of each serial number byte set to zero e.g. 00-04-03-07-08-0b which should have been reported to Cosm as 00-04-a3-27-c8-bb, so I now have a set of dead feed graphs that I cannot delete or update.  Since this happened the first time the egg was powered, this is the feed the main AQE website picks up... doh!

 

 

Good luck!

Alan

Hi Alan,
I'm happy to flash the shield using the CLI method like Damon mentioned, that's worked for me before.  Since asking my question I found the sensor shield firmware at https://github.com/WickedDevice/aqe_sensor_interface_shield, dated 5th feb 2013 ( a bit newer than my running version) so I'll give that a go.

This may be relevant to you...
 I had a whole bunch of screwy data & extra datastreams when I started using my egg and I pinged Joe Saavedra from AQE a mail to get the 'full access' key for COSM. Then you can delete datapoints / whole datastreams to tidy things up.
I wrote up a quick guide at http://www.tumblr.com/blog/turboisland which might be of use.

Cheers

Toby
