I'm not looking forward to winter, because the ex-manufacturing space I moved into last year is brutally cold and drafty. I spent last winter making futile attempts to caulk this and shrink-wrap that, only to achieve zero perceptible gains in thermal efficiency; the space is simply too deteriorated on all six sides for me to determine where I can best make a dent.
What I need is a focused plan, a way of determining where the largest heat leaks are so I can tackle those first. And I think I've found my solution in this awesome-looking Seek Thermal Smartphone Infrared Camera.
The tiny, three-inch, half-ounce, $199 device brings something close to military- or industrial-grade thermal imaging to the common man with the common paycheck. (A commercial infrared camera would run you four figures.) You plug it into the bottom of your smartphone and bang, you've got an image on your screen that can accurately display a range of temperatures from -40° Celsius (-40° Fahrenheit) up to 330° C (626° F).
Here's a demo of it in action from Android Police's David Ruddock, and you can skip the first 30 seconds of pitch-blackness:
The camera comes in both Android- and iPhone-compatible versions. And if you're wondering about the dongle form factor, that's Seek's effort to futureproof it; the developers of the closest competing device, the $349 Flir One, made the poor decision to build their camera into an external case—that only fits an iPhone 5 or 5s.
