Wearing my all-inclusive belt bag on my waist
Nearly a decade ago, you would have seen me wearing all sorts of gadgets around my waist, as evidenced by this television broadcast. The problem with this was clearly illustrated in that video - it takes a bit of time to put them all on the belt, however useful they may be.
I haven't let go of the carry-them-all attitude, but things have worked in my favour. A lot of the gadgets I had to carry separately were now integrated into a single device (smartphone). That meant less stuff to carry, and I was able to reduce the number of pouches and bags on the belt over the years. I ended up with a phone and an external battery each in a holster, and a bag that held adapters, cables, and other miscellany.
iPhone 6S Plus and external battery are easily accessible
But then large iPhones came along. When I put it on my belt, it occupied a sizable area of my waist. This got me thinking: since the phone is thin enough, maybe I could put it in a belt bag that can store other stuff with it. And this is how I now just have this one bag hanging from my waist.
As you can see here, my iPhone 6S Plus and the slim external battery fit nicely into the front pockets of the bag. They're accessible by opening up the flap usually held in place with a hook-and-loop fastener. I also have a paper clip there in case I need to change the SIM card or poke a reset button.
Of course, there's a lot more hiding behind. Let's take a look at the rear compartment.

My home isn't particularly wasteful when it comes to electricity spending - it rarely exceeds 200kWh per month except for hot summer months. Still, I wanted to see the real-time usage to make further optimizations. After browsing through myriads of metering solutions, both domestic and abroad, I settled on a particular product sold by Seojun Electric.
Officially called "Smart Power & Charge Meter" model SJPM-B70 (I'll simply refer to it as "smart meter" hereafter), it connects to the main power line going through the primary circuit breaker inside the house. Once installed, it constantly measures and stores the power consumption data. This can then be accessed in real time by a smartphone via Bluetooth technology.
Current sensor and the power plug for the meter
The main thing going for this product is its cost and simplicity. It only costs KRW 42,000 (US$35) online, not much more than the power monitors you plug into an outlet. And you merely need to hook the sensor and the power plug into the right place to get it working - no further maintenance required. Instructions on how to do that are shown with diagrams in the included guide.
You also don't need to sign up for anything as the data stays in your house, fully under your control. As I don't need to have my consumption data shared and analyzed over the internet cloud, this was actually a plus for me. And in case you wanted to show that you have this smart meter installed, the package provides two blue stickers to let you do just that.
