After struggling for two days, I finally succeeded in flying a Tello toy drone automatically.
I often use the toy drone priced at around 5,000 yen. It's good for practice because it's safe to fly indoors, and it's less stable than the bigger one (like a Phantom one) so I can improve its flight stability by using it.
Recently, I bought a Ryze Tech Tello toy drone, which is expensive for a toy drone. Because I found out that the Tello could be flown automatically from a book.
At first, I installed the latest version of Scratch without reading the book carefully. And I became confused because the action of the application was different from the description in the book. I solved this problem by installing the old version "Scratch 2.0 Offline Editor" again.
The book is written for Windows, which made me even more confused because I usually use Mac. One of the different parts is to run a node.js but it's explained in Sky DRONE's video "Programming RYZE Tello with Scratch (Mac edition)" and, which was helpful for me.
Unlike manual operation, there are restrictions such as not being able to do more than two operations at the same time, but it seems to be possible to do some interesting demos.
The other day, I was handed a sheaf of papers by a longtime friend, saying "Do you want to read this?" In fact, the copy over 40 pages was a travel journal about when I went to London 26 years ago with her.
She likes writing and has literary talent. She wrote a very detailed journal about our entire trip of the time. Of course, I can remember I went to London, but I have only a vague memory of what the hotel was like and the detailed itinerary.
Back in those days, the Internet was not spread, so I had only guidebooks to rely on. The photos that I took were analog ones of course.
When I started to read it with my heart thumping a little, it brought back my dim memories and as if they are updated vividly and I was moved. I feel like having a treasure, cannot be replaced by anything. If I take a long trip one day, I would definitely like to write a travel journal.
She also wrote a novel that a girl travels back to a sword training yard of samurai in the end of the Edo Period in Kyoto. I read it before and it brought tears to my eyes. I want the novel to be turned into a book, but she has no interest in publication because she said she wrote it merely for her pleasure. (H.S)
The purpose of the trip to London was visiting here, where is the residence of Freddie Mercury, who died in 1991. In the film "Bohemian Rhapsody", there was a similar scene to the appearance of the house in this photo.
Messages from fans were written all over on the brick wall of Freddie's house. We visited here again two days later and left flowers and letters.
Last Friday, I was surprised to see that there was a heavy machinery moving on a landslide-like steep slope. The photograph was taken from a distance, so it's hard to see that there's a heavy machinery, though.
The heavy machinery was a power shovel. It was probably hung with a wire from the top of the slope. The slope might be as steep as 45 degrees, so even just sitting in the driver's seat must be scared.
I don't know if it's a kind of their usual work, but I was impressed by the skills and courage of those construction workers.
At the New Year's press conference, the governor said that he wanted to begin consideration of relocation of Fukui prefectural office building from next fiscal year.
Actually, there was a lot of criticism about the scenery that the office building is located in the Fukui Castle Ruins, where the beautiful stone walls remain, water birds rest in the moat surrounded the walls and cherry blossom trees bloom in spring.
Then, where should they relocate it? And, how should they use the site?
One of Fukui Chamber of Commerce and Industry's suggestion is that to renovate and reuse several existing buildings located in the center of Fukui City. In that case, the place would be separated for each section. But therefore, that might help to create new flow of people and make the town more lively.
And as for the site, they have a plan to create Fukui Castle Ruins Park. I hope that the park will be a resting place that people could know the history as well. Also, it would be nice if there were a small concert hall, a restaurant and a cafe. I think that the plan will be decided in four years later, before Hokuriku Shinkansen will be extended to Fukui Prefecture. I look forward to that day. (H.S)
