We have a refrigerator downstairs that once in a while gets left open, and since it’s downstairs, we sometimes don’t catch it in time to save to food. Will and I decided to make something to help solve this.
Our plan is to use our Particle Proton (a tiny Wi-Fi development kit) and connect a temperature sensor. We’ll report that temp to “the cloud” and if the temp rises above some threshold, we’ll use IFTTT to text or call us to let us know to check the fridge.
I got us a free DS18B20 temperature sensor as a sample from Maxim Integrated (how cool is that?) and found some nice sample code here.
The prototype is now sitting in the fridge (photo above), dutifully sending out the temp every 10 seconds. The code is crazy simple.

UPDATE: The 2200mAh 3.7V battery didn’t last until morning, so Next up will be to see whether there’s a way to reduce power consumption. Fewer temp reports to the cloud will obviously help. I wonder if there’s a “low power mode”.
Saint Paul’s First National Bank building has a new owner and they’ve turned off the wonderful, nostalgic red neon “1” until further notice because of wind damage.
I know; it’s only a sign, and I suppose I shouldn’t be sad. But I think all of my kids have had that point at which they can recognize that we’re close to home, and it’s by seeing the red number one.
Also, I just like neon. There’s something warm and simple and different about it. (Go admire this amazing picture.) LED restorations are wonderful and I’m glad that iconic signs sometimes get new life that way (for example, the Schmidt brewery sign), but it’s not the same.
If you enjoyed The Martian, you might like The Cave of Night, an episode of the excellent 1950s X Minus One radio series; herculean efforts to save a stranded astronaut. Listen all the way to the end.
Old time radio disclaimer: Yes, it is a little dated – after all, it’s 1950s radio – but it actually holds up quite nicely and is well done and entertaining. The sci-fi and suspense genres hold up better than comedy, oftentimes.
The months preceding an election can be revealing in unintentional ways. Candidates, parties, and PACs fill the airwaves and our mailboxes with ideas and arguments, hoping to win our votes. This presents special challenges for the American Christian; challenges that, when understood, can have a significant effect on our daily lives.
As elections come into view, they bring with them the topics of the day. Sometimes these topics are transient and will scarcely be remembered 20 years later. Oftentimes the crucial themes of human existence will have reemerged. And we have, with our vote, the opportunity to affect our world.
The recently released movie Blue Like Jazz is an interesting genre-challenging movie that will, or at least should, stir up some excellent conversation. Based on Don Miller’s semi-autobiographical book by the same title, it deals with Christian spirituality without being what would commonly be thought of as a Christian movie.
Some controversy surrounds the movie. It has an honesty and authenticity that connects with some and troubles others. It’s easy to understand why. Seeing uncomfortable or embarrassing church moments played out, or secular college campus life portrayed (albeit not condoned), are things you don’t expect from a “Christian movie”.
These were conscious decisions by Miller and director Steve Taylor. They, along with lead actor Marshall Altman, discussed this approach after a pre-screening of the movie at Macalester College in Saint Paul. Taylor spent some time describing some of the difficulties he encountered in making this movie. At one point, he emotionally described how some in the broader Christian movie industry had made statements and decisions that (it seemed to me) broke his heart. It was a sad moment.
