FLIR ONE Pro - Inside Uses

Oven-baked spaghetti looks innocuous at a casual glance

Indoor uses of thermographic imaging camera include finding leaks of heat or water, owing to the fact that people doing repairs may have the budget and the repeated usage that justify owning such a device. But as the cost to buy one goes down and the size becomes small enough to carry in a pocket, more uses come up. The one I found useful in raising kids is cooking and food safety. As you can see here, a bowl of spaghetti straight out of an oven didn't look particularly dangerous at first...

But the bowl is quite hot at over 85C, enough to cause a burn

But with FLIR ONE Pro, you could see that the handle was quite hot. The spaghetti itself was also sizzling at over 70C. This image served as a good way to teach my kids why they should be careful with a bowl that came out of an oven.

FLIR ONE Pro - Impressions & Outside Uses

I have been a long time user of a FLIR ONE, an infrared thermographic camera module that connects to a smartphone. This type of camera visualizes the hot and cold spots of a subject by measuring infrared emissions. Such cameras are generally quite expensive, but by reducing it to just the camera module and relegating much of the operation to the connected smartphone, having it at a much lower price point became possible. That's how the FLIR ONE series came about.

More specifically, I own a first generation of the series, which is shaped to fit on an iPhone 5 or 5S only. Subsequent generations were redesigned to support a wide range of phones. So I was quite thankful to have given the chance by FLIR to test out the high-end version of their latest generation smartphone attachment - the FLIR ONE Pro. I was eager to see what sorts of improvements were made during the past few years.

Contents of the FLIR ONE Pro package

The product came in a colourful box that contained the main module, a USB-C charging cable, a compact carrying pouch, and some leaflets. The general style of the packaging had remained constant and professional, and the addition of a pouch was a nice touch since the module really shines when it can be brought to everywhere.

The quick start guide basically tells you to connect the module to your smartphone and install the FLIR ONE app. It is really a plug-and-go affair, so the simplicity is understandable. I do wonder if basic app functions could have been explained on paper a bit further, however.

Size of FLIR One 1st generation (top left) and FLIR ONE Pro (bottom right) compared with a transit card (bottom left)

Comparing to the first generation module, the look of the main component - the thermographic sensor and the regular camera bundle - hasn't changed much. However, the overall packaging has changed dramatically. The first generation was shaped to encase an iPhone 5/5S, so the long shape allowed it to house a large battery. It also has a recalibration / power switch next to the sensor bundle.

The FLIR ONE Pro, on the other hand, was designed to fit on a data/charging port of a phone and is smaller than a transit card. In order to accommodate thick phone cases, the length of the connector on the module is adjustable through the dial just below it. In order to make it compact, however, the integrated battery is much smaller and runs shorter than the first generation. There is a small power button at the bottom with status light. Automatic recalibration function did away with a need for a manual button.

I bought my first car and it’s an electric vehicle

Looking at the dashboard of Bolt EV from the driver’s seat

Up until now, I’ve been driving the car my parents used to drive, and I had been putting off on buying my own until something that could satiate my fondness for technology would come along. And I finally found that car - Chevrolet Bolt EV, a fully battery powered electric vehicle. I pre-ordered this year’s version in January, and was expected to get it by late July, but I got lucky and I picked it up today. The car is very responsive, which I like.

Charging the Bolt EV at a highway service area

The car wasn’t fully charged at the time of the handover - it only had enough charge for about 150km of driving. So I’m charging it at a service area as I write this after driving about 50km. I still have more than 300km to go, so hopefully it’ll get charged enough for me to return home.

Awarded by the World Bank Group

Me and the head of KPX Training Academy received awards at KGID 2018

As the one responsible for the foreign relations and overseas training at the KPX Training Academy (formerly KPX Education Center), I had been cooperating with the Korea Green Growth Trust Fund (KGGTF), a part of World Bank Group, in running their Korea Green Growth Knowledge Exchange (KGGKE) since early 2017. The program provided by KPX within KGGKE introduces the how the electric power market and the system (power grid) is operated, how the short and long term planning is done, and what efforts have been taking place in regards to the renewable energy. Most of the participants have reacted positively to the our program.

In extending this cooperation, I was invited to the Korea Green Innovation Days (KGID) 2018 event held between May 17 and 18 in Seoul, hosted by the World Bank Group and KGGTF. There, I was given the opportunity to introduce the overseas training programs offered by the KPX Training Academy to the participants of the event at one of the working sessions. Several countries have shown interest in starting discussions for new programs.

Recognizing all these efforts, my company and I were awarded the KGGTF Partner Award (received by the head of the Training Academy, Mr. Bae) and the KGGTF Green Connector Award, respectively, at the end of the event. I thank everyone at my company that helped putting together and running the programs successfully. Several Korean newspapers have reported of this occasion.

100-minute tracking of Jupiter

Jupiter and the Galilean moons seen on 00:44, April 20, 2018

Jupiter and its four major satellites (Galilean moons) are good targets for time lapse photography because of the relatively rapid movement. The rotational period of the planet is slightly less than 10 hours, and Io, the innermost of the Galilean moons, orbits the planet in about 42.5 hours. Under good conditions, these things become noticeable over a span of just about an hour.

Shortly after midnight of April 20, 2018, Io came out from behind Jupiter on the left side, while the Great Red Spot was moving towards the back of the planet on the right side after being in the center. These were all captured on my camera as I took 597 photos of the Jovian system over a period of 100 minutes between midnight and 01:40AM. The photos were then stacked and processed in 1-minute intervals (6 photos on average), like the one you see above, then put together into video as you see below.

I think it shows the dynamics of these celestial objects quite well. Now that I have a good grasp of the workflow for making a planetary animation, I should be able to make a similar one for Mars when it approaches Earth close enough to be seen as half the apparent size of Jupiter next July. Before wrapping up, here's a bonus picture of the Jovian system that I took just after photographing the Sombrero Galaxy. You can actually see Io casting a tiny shadow on Jupiter. I thought I would never see that sort of thing on my telescope.
