Project SensorWeb is an experiment from the Connected Devices group at Mozilla in open publishing of environmental data. I am excited about this experiment because we’ve had some serious air quality discoveries in Portland recently – our air is possibly the worst in the USA, and bad enough that mega-activists like Erin Brockovich are getting involved.
A couple of weeks ago, Eddie and Evan from Project SensorWeb helped me put together a NodeMCU board and a PM2.5 sensor so I could set up an air quality sensor in Portland to report to their network. They’re still setting up the project so I haven’t gotten the configuration info from them yet…
But you don’t need the SensorWeb server to get your sensor up and running and pushing data to your own server! I want a copy of the data for myself anyway, to be able to do my own visualizations and notifications. I can then forward the data on to SensorWeb.
So I started by flashing the current version of the SensorWeb code to the device, which is a Nodemcu 0.9 board with an ESP8266 wifi chip on board, and a PM2.5 sensor attached to it.
I used Kumar Rishav’s excellent step-by-step post to get through the process.
Some things I learned along the way:
- On Mac OS X you need a serial port driver in order for the Arduino IDE to detect the board.
- After much gnashing of teeth, I discovered that you can’t have the PM2.5 sensor plugged into the board when you flash it.
After getting the regular version flashed correctly, I tested with Kumar’s API key and device id, and confirmed it was reporting the data correctly to the SensorWeb server.
Now for the changes.
- I set up the Maker channel on IFTTT, which allows me post data to an HTTP endpoint to get it into IFTTT’s system.
- I then created a new IFTTT recipe that accepts the data from the device and pushes it into a Google spreadsheet.
- I forked the SensorWeb code and modified it to post to the Maker channel instead of the SensorWeb server.
I flashed the device and viola, it is publishing data to my spreadsheet.
And now once SensorWeb is ready to take new devices, I can set up a new IFTTT recipe to forward the posts to them, allowing me to own my own data and also publish to the project!
Last month I spent a week working on IoT projects with a group of 40 researchers, designers and coders… in Anstruther, a small fishing village in Scotland. Not a high-tech hub, but that was the point. We immersed ourselves in a small community with limited connectivity and interesting weather (and fantastic F&C) in order to explore how they use technology and how ubiquitous physical computing might be woven into their lives.
The ideamonsters behind this event were Michelle Thorne and Jon Rogers, who are putting on a series of these exploratory events around the world this year as part of the Mozilla Foundation’s Open IoT Studio. The two previous editions of this event were a train caravan in India and a fablab sprint in Berlin (which I also attended, and will write up as well. I SWEAR.).
Michelle and Jon will be writing a proper summary of the week as a whole, so I’m going to focus on the project my group built: Bubble.
From research conducted with local fishing folk, farmers from a bit inland, and a group of teenagers from the local school, we figured out a few things:
- Mobile connectivity is sparse and unreliable throughout the whole region. In this particular town, only about half the town had any service.
- The important information, places and things aren’t immediately obvious unless you know a local.
- Just like I was, growing up in a small town: The kids are just looking for something to do.
Initially we focused on the teens… fun things like virtual secret messaging at the red telephone boxes. Imagine you connect to the wifi at the phone box, and the captive portal is a web UI for leaving and receiving secret messages. Perhaps they’re only read once before dying, like a hyperlocal Snapchat. Perhaps the system is user-less, mediated only by secret combinations of emojis as keys. The street corner becomes the hangout, physically and digitally.
We meandered to public messaging from there, thinking about how there’s so much to learn and share about the physical space. What’s the story behind the messages to fairies that are being left in that phone box? I can see the island off the coast from here – what’s it called and what’s out there? Who the hell is Urquardt and what’s a “wynd”? Maybe we make a public message board as well – disconnected from the internet but connected to anything within view.
We kept going back to the physical space. We talked about a virtual graffiti wall, and then started exploring AR and ways of marking up the surroundings – the people, the history, the local pro-tip on which fish and chips shop is the best. But all of this available only to people in close physical proximity.
Given the context and the constraints, as well as watching direction some of the other groups were going in, we started designing a general approach to bringing digital interactivity to disconnected spaces.
The first cut is Bubble: A wi-fi access point with a captive portal that opens a web page that displays an augmented reality view of your immediate surroundings, with messages overlaid on what you’re seeing:
A few implementation notes:
- We used a Raspberry Pi 3, running as a wi-fi access point.
- It ran a node.js script that served up the captive portal web UI.
- The web UI used getUserMedia to access the device camera awe.js for the AR bits and A-Frame for a VR backup view on iOS.
- We designed a logo and descriptive text and then lasercut some plaques to put up where hotspots are.
Designs, board, battery and boxes:
- Captive portals are hobbled web pages. You can’t do things like use getUserMedia to get access to the camera.
- iOS doesn’t have *any* way to let web pages access the camera.
- Power can be hard. We talked about solar and other ways of powering these.
- Gotta hope they don’t get nicked.
Web IDE has gone though some twists and turns as a feature in Firefox, but one thing has remained constant for me: When I launch an app, I *always* want to debug it. Having to repeatedly wait and hit the wrench button has always bothered me. During a development session I may do this hundreds of times.
So I wrote a small Firefox add-on that changes the functionality of the “play” button in Web IDE to also open the Developer Tools once the app has launched.
Warning: It’s not pretty. There’s probably a better way to do it. Take a look at the source here and let me know if you have ideas.
A couple of other things I want to add:
- First force-stop app when you hit Play. Currently the new app source doesn’t get reloaded because the old app instance is running, which is wrong and maddening.
- Always show dev tools. The way the pop in and out is very heavy feeling. Just keep them open all the time.
I love Pocket and I love Firefox.
But two things were driving me batty about the Pocket feature built into Firefox:
1. The design of the popup experience when you save a page to Pocket is… unfortunate. It stays up far too long, and it doesn’t go away when you switch tabs. Yeah, it stays open for a given URL even when you’re on a tab with a completely different URL! But regardless of whether you think that’s as crazy as I do, I never want to add tags so just don’t need it at all.
2. The Pocket toolbar button doesn’t indicate whether you’ve already saved the page or not. You have to click the button to figure it out. Now this might not be a problem for everyone. But the way I use my browser can best be described as “tabsplosion”. I don’t know when or where these tabs come from, or how they get there, or whether I saved it already or not. So this tiny piece of ambient visual signal would be useful for me.
So I took a couple of hours over the last few evenings and scratched the itch. I made a Firefox add-on which does the following:
* Adds a new Pocket button to the toolbar. (You can remove the old one by right-clicking it and choosing “Remove from Toolbar”). Mine is red. I want to make one that has nice gold double-stitching on it…
* The new button shows a check mark badge when the page is already saved.
* You can click the button to either add or remove the page from Pocket.
* No popup.
That’s it. Simple, clear and out of your way.

Around 1,100 Mozillians will be in Portland next week. WELCOME!
Here is a list of things I recommend that you see, do, eat and drink and some handy tips. I’ve focused on places that are in or near downtown, though included some spots worth going out of your way for.
That said, downtown is not Portland. Well, obviously it’s part of it, duh. But it’s not overly representative of the Portland you’ve heard so much about. Get out of downtown for an evening or afternoon – and check out one of the neighborhoods. Nothing listed here is very far from downtown – Portland is pretty small.
I’ve left a LOT out. And forgot the rest. If you have recommendations, leave them in the comments.
UPDATE: Blue Star donuts, which are far more delicious but far less penis-shaped than Voodoo donuts, will be giving away free beignets on Friday Dec 5.
- Portland has no Uber or Uber-like services. If you have Car2Go in your city you can use that here too. Curb is the app for local taxi service through a couple of providers. You can get a bus to pretty much anywhere without too much of a wait. Ride the MAX and streetcar if you’re headed to areas that they service.
- Oregon has no sales tax. Do your Christmas shopping while you’re here.
- It gets dark around 16:30 – 17:00, so factor that into any plans for hikes, etc.
- If you go into the mountains, check the road conditions to see if you need chains for the car, or if the area is accessible at all.
- Go to Powell’s books. Go a few times. Then go back again. Check out the Science Fiction pillar there – how many have you read?
- Get high… for a good view of the city: Have a drink at Departures, dinner at Portland City Grill or visit Pittock Mansion for great views of the city. Even driving over the Fremont bridge (Highway 405) provides a spectacular view of downtown, the Willamette River and our many bridges.
- There aren’t a ton of restaurants/bars/coffeehouses that can hold large numbers of people. If you break up into groups of four (max), you’ll have a much better time and the servers, chefs, baristas and bartenders will like you for it.
- Be patient. Oregon is home to the slow-food movement in America. Regardless if this explains why your coffee took 20 f***ing minutes to make, it’ll make you feel better to think about that. See also the above note about small group sizes to mitigate the waits.
- Tipping: I tip a dollar for a good coffee. I generally tip ~20% for any kind of sit-down meal. But I also worked as a barista, server and chef before getting into tech, so I’m biased towards tipping 😉
CARTS – Just the 9th & Alder pod for the purposes of this post. If you’re from California – up here they are not “food trucks”, they are “food carts”… even when they are trucks.
- Hoang’s – Get soup #17.
- Nong’s khao man gai – Simple and good and oddly famous.
- Wolf & Bear – Israeli street food that is amazing. And vegan.
- Güero – Excellent tortas. Add an egg.
- La Jarochita 2 – Great Mexican cart. The only Mexican cart (aside from Güero) worth going to at the 9th and Alder cart pod.
- Brunch Box – A cart that graduated to a proper storefront, but is right by the 9th and Alder carts. Great egg sandwiches for breakfast (try the Black and Blue) and terribly good burgers the rest of time. Very fast.
- Kargi Gogo – Georgian food. The country, not the American state. Irakli says it’s legit too.
- Multnomah Whiskey Library
- Clyde Common
- Pepe le Moko
- Bailey’s Taproom
- Courier – They also make fresh canneles daily.
- Heart – Excellent coffee.
- Coffeehouse Northwest
- Case Study
- Coava – Not downtown but my favorite coffee roaster in town.
- Ristretto – Not downtown, but fantastic coffee in beautiful spaces. The Nicolai location is especially great – check out the custom metalwork and crazy woodwork, and visit Schoolhouse Electric in the same space.
EAT – I’ve only noted a few of my go-to places, or those that are near where Mozillians are staying, or open late, etc. I’ve got a somewhat-up-to-date list here with more recommendations, but there’s just really too much to cover. Go out and explore.
- Clyde Common – Always interesting menu, good whiskey selection, great cocktails. Fries + harissa and a cocktail is a great way to end your day and start your evening.
- Tasty and Alder (downtown) – Shared plates, everything is good.
- Luc Lac – Vietnamese + cocktails, serves food VERY late, and closest place worth going to that’s also near the Waterfront Marriot.
- Bunk – Excellent sandwiches.
- Lardo – Excellent sandwiches as well.
- Racion – Amazing cocktails and fun Spanish-tinged molecular gastronomy.
- Little Big Burger – Fast and good late night burger.
- Not downtown, but places I always want to go back to…
- Biwa – Izakaya, open late, always amazing. Burger served only after 11pm.
- Tarad – Northern Thai food, open late. Pok Pok gets all the attention but after living in northern Thailand, this is where we go for the real thing.
- Mee Sen – Another good Northern Thai food spot we go to.
- Podnah’s BBQ – Worth heading up into NE Portland for.
- La Taq – Next door to Podnah’s, fantastic Mexican bar food.
- Sweedeedee – Most likely to feel like you’re in Portlandia at this spot. Amazing house-baked breads. Tiny. Expect a long wait but good people watching and excellent food.
- Por Que No (Mississippi location) – Great tacos.
- Ha & VL – Get the special soup of the day, whatever it is.
NEIGHBORHOODS – Places to walk, eat, drink, shop and experience parts of Portland that are far more interesting than downtown.
- Alberta St – Between NE 15th Ave and NE 31st Ave
- Belmont St – A few blocks on either side of SE Belmont and SE 34th
- Division St – Between SE 30th and SE 39th
- East Burnside – From NE Grand Ave to NE 12th Ave and then up and down NE 28th and Burnside
- Hawthorne Blvd – Between SE 32nd Ave and SE 49th Ave
- N Mississippi Ave – Between N Fremont Ave and N Skidmore Ave
- NW 23rd Ave – Between W Burnside and NW Thurman Ave
- NE Williams Ave – Between NE Fremont Ave and NE Skidmore Ave
- Columbia Gorge – See Multnomah Falls, the view from Vista House, climb Beacon Rock, stop at the Bonneville Dam and see Herman the Sturgeon, drive across the Bridge of the Gods (and back), then go for lunch at one of the Hood River breweries. Some easy/moderate 1-2 hour hikes I like: Angel’s Rest, the Multnomah/Wahkeena Falls loop, Triple Falls, Horsetail Falls, Punchbowl Falls, all listed here.
- Mount Hood – Drive out Highway 26 to the historic Timberline Lodge with amazing views of Mt Hood (if it’s clear), then down to Hood River and head home through the Columbia Gorge on Hwy 84.
- Mount St Helens – A couple of hours north, but the view of the blast zone and crater from the visitor center on the NW side is well worth it if the view is clear. On the SE side you can hike one mile underground through Ape Cave, and check out the amazing rock formations and brave the cable bridge at Lava Canyon.
- Oregon Coast – About two hours drive. Walk the promenade at Seaside, get ice cream at Tillamook, watch storms from the tip of Oregon at the mouth of the Columbia river.
We use Mailman for mailing list management at Mozilla. However, we haven’t been able to control spam on those lists. Not only does spam not get caught before hitting Mailman, the built-in spam rules don’t work – I configured the rules to discard anything above spam level 1, and tons of spam is still held for moderation. But identification *does* work… so we can just ignore the moderation queue forever and move on with life, right? No. Because we have another problem: The newsgroups support means that valid posts might be held for processing because Mailman doesn’t know the sender is valid because they subscribed through Google Groups. So we have to view the lists and mark those messages as valid and add the sender to the valid-senders list. To cap it all off, in the long tradition of open source user interface design, Mailman has a full featured but RSI-inducing UI for managing all of this.
So if you’re an admin for a bunch of Mailman lists, here’s a mitigation that might make your day suck just a little bit less:
I wrote a bookmarklet that will do the following for all messages held for moderation:
- Select the radio button to discard the message
- Check the box to auto-discard from that sender
- Check the box to ban the sender from ever subscribing again
To install, drag this link to your bookmarks Toolbar: Mailman – discard and ban all
Remember to make VERY sure that none of the messages are valid before executing this bookmarklet… not only because valid messages will be discarded and their senders will be banned, but also because the UI for removing addresses from the block-list in Mailman is even worse than the one for moderation.
