Annular Solar Eclipse of 2019

My Nikon P1000 was set up on the roof of the Marina Barrage along with other cameras and telescopes

An annular solar eclipse happening on the Boxing Day in Singapore sounded like a great excuse to have a year-end family trip there, so I acted on it. As expected, multiple venues across the city-state provided spots for people to view and photograph the phenomenon. I picked Marina Barrage as it would have longer totality and snacks.

My family arrived nearly two hours before the start, but a lot of equipment were already on the roof. Once our stuff was set up, my daughters saw the Sun through the handheld protective film or binoculars while I took photos in intervals.One thing that concerned me was the weather, as it was supposed to be cloudy with a chance of rain that day. While the sky was mostly clear during the early stages, clouds began to build up as we neared the totality.

The clouds were both a curse and a blessing. It became cumbersome to track and photograph the Sun through the camera on the tripod, since I needed to fiddle with the settings every now and then. But the clouds often became just thick enough for my iPhone to take the ongoing eclipse directly without any filters, letting me get these nice photos you see above. As a result, both the phone and the camera had their share of the action.

The clouds that moved in about half way through the 2 minutes of totality created a breathtaking view - people could see the "ring" of Sun with naked eyes. That was quite an experience. Alas, the clouds blocking the Sun became thicker and more frequent after that, so they became much more annoying in the second half of the eclipse. I was getting a lot more gaps in the interval photos I was taking, so I finished my session about an hour early and went sightseeing around the Marina Bay with my family to much satisfaction.

Making external storage work on iPhones with iOS 13

- or, why do I get "too much power" error with my drive and how do I fix it? -

Apple's official Lightning to USB Camera Adapter

With iOS 13, native support of USB external storage was introduced to iPhones. Files stored externally can be accessed from the Files app included in the OS. Other apps can do it as well if it can connect to this Files app. Sadly, modern iPhones' external port of choice is Lightning, which means you either buy a storage device with a Lightning port or get an adapter to connect a USB device. This is where things get complicated.

I bought a Lexar MicroSD to Lightning Reader (part # LRWMLBNL) more than three years ago. It connects directly to the Lightning port and I can open files using a dedicated app. Apple MFI certified storage can supposedly work with the iOS 13's Files app, but that wasn't the case here despite the certification. Adding insult to injury, its app had not been updated in more than two years - the screen resolution and the file sharing functions were outdated. I needed a different solution.

Apple sells many types of USB adapters, one of which is the Lightning to USB Camera Adapter you see above (US$29). It can be connected to a camera for transferring photos and videos, hence the name. Other devices could be plugged in as long as the OS recognizes it, like keyboard, MIDI equipment, or Ethernet adapter. iOS 13 expands this to general storage and mouse.

Plugging in a USB flash drive directly do the adapter results in a "Cannot Use Accessory: This accessory requires too much power" error

So I bought this adapter expecting that any low-power storage devices like USB flash drives and memory card reader could be plugged in directly for my file management uses. Boy was I so wrong. Of the multitudes of flash drives and card readers I own, all of them, save for one, caused the "too much power" error you see here. This was bizarre because they shouldn't consume enough power for this to appear. There had to be a reason and a way around this, so I decided to dig in.
