Hello list,

I wanted to let you know a little bit about an event in Chicago last week.  I haven't gotten a chance to do a full writeup yet, but there was a great group of participants from Chicago, NYC, Berkeley, and Philadelphia that got 12 Eggs built and [partially] deployed.  Not only that, but quite a few smart people did some thinking about the data side and got some basic software/web prototypes built.  We have tried to do this quite a few times in the past and finally were successful.

Definitely check out the pics here:

One of the best parts of doing this event is that we've got a legit, active community now locally in Chicago who are really excited about the project and are independently moving it forward.  They have the first deployment in North America of any mass and are using the most up-to-date hardware we have.  BUT, they are running into issues with sensors acting up, odd-looking data, and doing some simple dataviz (this last part we'll have native tools built to help with soon).  So, I am going to re-post a bit of their conversation from the comments area of the event into this thread and have them move over here so that they can get some help from the wealth of experience in this group. It's long, but please power through it. Thanks!

    Do we have a map of where the eggs went and what streams are associated in cosm? I know there is a Google map floating around, any chance someone can share that with me?

    Adam: I got on a plane while deployment was happening. I'm not sure if we have an up-to-date map of where sensors actually went. Can I send you a DM on twitter or a pvt email? I don't want to post the map the deployment team created on day 1 because I believe it contains home addresses with names.

    Also: how did we do yesterday? How many eggs deployed? Do we have a running list of Cosm feeds? Here is the feed for the official EPA sensor at 327 S. Franklin: https://cosm.com/feeds/68943

    Adam: Charlie Catlett created a map, which I know Patrick had a link to. Javaun: I saw a list of several names associated with eggs. I have number 8, but am not sure that means that all eight went out the door. Alec: [Welcome!] As I understand it there were all pre-programmed to connect to individual feeds at Cosm. i.e. you do not need to associate your eggs to a personal account. However I searched on Cosm and could not figure out how to see feed data (Ed? Joe? help here?)

    Update on enclosures: I checked mine this morning and discovered that mine did have some leakage. And as my Nanode was not on standoffs it appears there might have been some shorting around the voltage regulator. I'll be curious to see my feed (see above) and see when/if data collection stopped.

    I was tooling around on Cosm late and found it in the search https://cosm.com/feeds?q=aqe This looks like the list of all the eggs (also found the source on Github)

    If someone can send me a list of the final resting places for eggs I will create a safe map.

    Charlie: I know of 5 eggs that went out into the wild; me, Bo, Collin, and Alec (two #3 & 5). Of those only Alec and I (#8) are posting data at the moment. I also know that four of the boards went with Raj for some of his trouble-shooting magic. When those return to SAIC working we'll dispatch them in new enclosures. As for making a map might I suggest we limit it to nearest intersection (e.g. I'm Augusta Blvd. & Rockwell St.)?

  • Patrick

    I have a list of who took an egg. I'll post them up shortly, probably in about an hour. My egg, number 6, has been sending data since last night. However, it is indoors for the moment.

    My feed can be seen at https://cosm.com/feeds/69068

    I had a couple thoughts about preventing leaking... one is to use clear silicone (available at hardware stores; if you want it to be clear then make sure it's the 'dries clear' variety, which often is opaque white when it goes on) and the other idea is to just tape up a hat out of a plastic bag that would fit over the top component.

    Hey Partrick: yup I see your feed is up. Also I should mention all egg holders (mother hens?) that if any of you need a custom length ethernet cable (i.e. personally I came up about 6' shy) just send me a measurement and we'll make one for you.

    Charlie - Of the 2 we have, #5 is currently set up at our house and #3 will be set up at Argonne (as close to the weather station as possible). However #3 is missing mounting bolts and nuts - so that will be resady to go as soon as we can get to the hardware store. Might you have any ideas for a location here at Argonne that meets our requirements?

  • Patrick

    I will post a link to a public google map (likely the one that was already started) and all storks can mark their egg(s) on it.

  • Rajesh Sankaran

    Yes, I have a bunch (4 ?) of them sitting in my car. I will test them in the next couple of days and try to debug them. I should be able to report back by the weekend.

    Alec: Wlecome, if you have not found your feeds yet, here are they - 5: https://cosm.com/feeds/69066 and 3:https://cosm.com/feeds/69064 . I am assuming 3 is not hooked up yet as it still has the 
    test value from yesterday, but 5 is doing great!

    Robb and Patrick: Do you mean the package is not water proof and you had some rain water leaking through?

  • Patrick
    Patrick

    Rajesh: I didn't put my unit outdoors; I was just commenting on someone else's reported leaking.

  • Colin Hutton

    I take it we didn't put the sealant on them properly then? I didn't take an egg because they were not ready when I ended up leaving.

  • Patrick
    Patrick

    We didn't put sealant on them; that didn't just make it into the time frame. I think the sealing/water protection is going to be part of the collective beta-testing/troubleshooting phase we're starting on now.

  • Patrick

    The map that was shared with me yesterday has quite a bit of old information (prospective storks, etc) including personal information. To start the conversation about a group map, how about the following: I start a dedicated gmail address (I already did, actually: ChicagoAir...@gmail.com), create a public map, and invite all storks to put their eggs on it, cautioning them to be aware that all information on the map will be public. Any changes, addendums, or alternate proposals?

  • Rajesh Sankaran

    I think we have to seal it water tight such that rain water does not get in there, but not make it air tight / or create a air-pocket. I am wondering about the fan - forced air flow and I hope it is not forcing the air on the sensors, but making sure a stream of fresh air is available to them to compute the levels. I am sure the air flow properties of the casing has some effect on the measurements and has to be compensated.

  • Patrick
    Patrick

    Also, are there any mapping enthusiasts or specialists that want to curate or manage the map? The default will be that it will be connected to the dedicated Gmail address for the map.

  • Patrick
    Patrick

    I'll wait a couple hours for comments, then post the map link up if I don't hear any changes to the plan or alternate ideas.

  • Robb Drinkwater

    It was me reporting that I had a leak (after putting on my apartment window sill. See pic on Facebook) but thankfully the electronics took it. Wouldn't have been an issue if my board was on stand-offs (which it is now). I'm kind of against glues and sealants. If we can come up with a design that can be laser cut and doesn't leak (or allows for water) then we can ship enclosures to people 'flat packed'. [I'm working on some ideas]

  • Patrick
    Patrick

    Robb: cool on your alternate design efforts. I'm reluctant to use a gooey sealant because it won't look as pretty! :-)

    FYI Joe: if you look at my feed https://cosm.com/feeds/69071 it looked like my CO sensor just crapped. Notice that there was a spike in humidity at about the same time; maybe the d.p. freaked? Gonna try a reset.

Raj,
I have an Atmel mkII ISP programmer you can borrow. I'll get it to Bo to get to you.
Re: Chicago Eggs Raj 8/3/12 7:21 AM
Robb, thats good. Let me check what the issue is and get back to you. Meanwhile, I have received two more eggs through Bo. I will do a final assessment of 
things this weekend and report. I will also try to set up all the working ones next to each other and have them send updates to Cosm for a day. If things
are stable, I will send them your way for enclosure building or, well, you can send me the enclosures.  

Re: Chicago Eggs Cesar Garcia Saez 8/3/12 8:21 AM

Good work guys!

It seems like you are on the express track of AQE deployment! I would suggest to check an email sent to the list about ten days ago to the list regarding Madrid workshops. We discovered there some clues there that appeared again during your deployment, like sun and aqes don't work well together, some enclosure design tips using recycled recipients and some trials testing 8 egg in the same place (under dcdcity username).

Best and keep the flow,
César

Nice to see more sensors being added to the map. How are the others doing?
Re: Chicago Eggs Raj 8/8/12 7:31 PM
Several are held up on my end. But they should all be in the wild by the weekend or 
latest by Monday / Tuesday.

Re: Chicago Eggs Raj 8/12/12 7:30 PM
Okay, here is the deal. After some testing, 

AEQ 9,10,11 are good. I have 3 other pieces, 2 Nanodes and 1 Sensor Interface shield that need to be 
programmed. The hardware is good, but looks like the firmware is kaput. I have managed an Atmega prog that 
will help me reflash the Interface shield, but I will need the ICSP to breath life into the Nanodes. 

Joe, can you help me with pointers to the compiled source - Hex/bin and the fw upload instructions? 

As far as having them out in the wild, I will update you guys soon. Most likely one will be in Charlie's house, 
Naperville, another at the Lab and we will find a home for the 3rd Egg (may be mine :)).

Thanks!
Rajesh
Re: Chicago Eggs Adam Laskowitz 8/14/12 7:58 AM
It seems only 1 egg is streaming now?
Re: Chicago Eggs Raj 8/15/12 2:46 PM

Now you should see 4. I put 3 more online. - Raj

Re: Chicago Eggs Adam Laskowitz 8/20/12 1:24 PM
Still only seeing 1 Raj.
Just #5
Re: Chicago Eggs Ben 8/21/12 8:33 AM
I'm seeing #3 and #5 in the cosm console.
Re: Chicago Eggs Raj 8/21/12 1:29 PM
Adam, There seems to be some issue with the eggs. Charlie has the number 5 and he 
reported that his hardware locked up every 1-2 days and my three eggs lock up every 4 - 8 hours. 
I have written to Joe about this issue and I guess he is working on the bugs. Right now, the best 
I can do is have a system that automatically resets the power to the devices every 3-4 hours. 
I will try that.

Cheers! 
Raj
Re: Chicago Eggs joe saavedra 8/21/12 1:33 PM
Yes, Raj is right --

It's the bug that affects both the Arduino Ethernet and Nanodes - basically they time out after some time (can range from a few hours to a few days) and then need a reset. I'll post the code *tonight* that includes the automatic reset when a connection timeout occurs.  This will cure the issue outright, so sorry it was left out of the working code that we put on the Chicago prototypes. It'll just require a flash of the Nanode (needs an FTDI cable).

Thanks guys, sorry about that, Chicagoans, look out for an email this evening.  I'll also update the Cosm feeds with metadata like I mentioned a couple weeks ago.

Talk soon --

joe

Re: Chicago Eggs vicatcu 8/21/12 2:15 PM

Joe,

I apologize, I haven't had the bandwidth to be involved with the Ethernet code much. I actually don't think a hack like that being proposed is necessary. The currently recommended library for the Nanode is EtherCard (github @jcw), and it handles DHCP lease renewal properly (which I suspect is the tour cause of these types of problems). If you are using EtherShield, that is no longer maintained. Migrating from one library to the other is not top too difficult either.

If I'm way off base, sorry... I'm writing this while on the road do I'm speculating without reading the code...

Regards,
Vic

Re: Chicago Eggs Raj 8/21/12 2:46 PM
Hi Vic, Joe,

    Thanks for your responses. Vic glad to meet you in cyber space, Joe has mentioned 
quite a bit about you! I am not sure if it is a DHCP lease issue. I can set Static IP to the 
devices and report back on how they are doing. Wait, even if I set static IP on the router, 
the device being unaware of it, will request IP at predefined time intervals and will get 
the same response. So that will not help me identify the problem. What I can do is to 
see if I can ping the devices (I am not in the same subnet now) after they have gone silent. 
That will help me see if there is an IP issue or if it is a buffer issue triggered by IP timeouts and 
such to begin with. Any other quick thoughts?

1. The Ethernet chip has gone into a weird state and dropped off the n/w
2. some thing has triggered a catastrophic break down of comm between the 
Ethernet chip and the ICSP programmed Processor. 
3. The I2C bus / Atmel has gone haywire and there is no new info to send to 
Cosm. 
4. Some other FW cavity exists that brings things to a grinding halt. 

Cheers!
Raj 
Re: Chicago Eggs patrickaroo 8/22/12 12:50 PM
Is anyone up for a get together?  I can offer our beautiful offices (Open Software Integrators) in the West Loop, along with some food and definitely beer.  We could hack on some sensors, some code, and otherwise catch up on the project.

Thoughts?

Re: [#AirQualityEgg] Re: Chicago Eggs JeffMu 8/22/12 1:01 PM
I am a Chicago AQE supporter and would love to meet up.  I work in the west loop as well.

ooooh.  I'd love to.  I am at Mich Ave/Ohio area but my after hours activities are cut off after next week.  :(    School starts.

I'd love to fix up #5 so I don't have to reset it every day.

Re: [#AirQualityEgg] Re: Chicago Eggs Robb Drinkwater 8/23/12 5:50 AM
It'd be great to get together and do some hacking. My Monday and Wednesday evenings also get busy starting next week, so sooner is better or at least not those days.
