Micro:bit, Mbot, and prgograming tool

Recent technology's progress is amazing. One is a progress of coding technology and second is a progress of IT-gadget.
Emergence of graphical programing tool like Scratch is a big innovation which makes programming easy to handle. And at the same time, it gadget like micro:bit, rasbery-pi emerge. I think both of them are indispensible for each other.

I happend to buy mbot 2 years before for my son's christmas present when he was 2 grade of elementary school. He liked it.

Mbot has many functions like
 - line detection
 - light detection
 - sonic detection
 - bluetooth interface
and also has a graphical programing tool like scratch but he prefered using its remote controller rather than using programing tool.

And about one year later, we happend to start Scratch on November 2017 and started going CoderDojo on March 2018 and it was a very big event, I think.
Scratch is a SNS programing platform and it is huge difference from mbot programing tool because he can connect to other people's code so he copyed other's programing with no assistance and posted them. And after starting CoderDojo he enthusiastically did it because at CoderDojo he can do it freely! At home, he was restricted doing Scratch by my wife because of homework, etc. Furthermore, he could ask something, seeing other children making code, teaching each other. I think giving such "envirnment" to them is very important point.
Scratch and CoderDojo is ideal envirnment. I admired this two genius idea.

 And last December, I bought micro:bit. I knew it at CoderDojo because one mentor demonstrated it. At that time, we couldn't handle it with Scratch but recently Scratch3.0 can handle it via bluetooth and it is cheap (around $20) so I decided to buy it.

Micro:bit is amazing IoT tool because it has
-bluetooth, micro usb, battery interface
-LED display
-writable rom
-thermometer
-ditecting lightness
-ditecting earth magnetism
-ditecting accelation
in a small chip-board with ceap price.
Micro:bit is very good IoT tool but before a year, it was not so intersting to me because it is a little restricted, it seemed to be like stand-alone device. But recent Scratch support is a huge bigstep because we can communicate it each other in real time.

And the most amazing point is that we can use it with very cheap prices (Scratch and CoderDojo is free and micro:bit is cheap and notebook computer is recently very low price and wifi is also very cheap!). It is awesome age !

Earthquake happend in Japan

On Friday afternoon, big earthquake had occured. I worked at office at Osaka. At first, next branch's team used TV conference to Tokyo office and tokyo team said earthquake had occured, and a few seconds later, we felt earthquake. Our office is at 11th floor and swing was very big so we felt very awful if our building was collapsed. It was about 2:30 PM. Afterthat, we switched our TV on and saw what happend in Japan, so our work had almost stopped afterthat. (safely, my house in Osaka and my parents and brother and sister's house in Shizuoka-pref. was safe) Magnitude 8.8 was very huge. Newspapers said it is the biggest magnitude earthquke in japan since authority had a record. Our hometown shizuoka was said to be occurd big earthquake since I was a child 30-40 years ago, so we had many training since i was a junior school, so at first I thought that earthquake at shizuoka had finally happend ! This eqrthquke had happend at touhoku-region so maybe many japanese thinked

Goldsmith College, UK

Image
When I was a graduated student, I went to London and enjoyed summer school at Goldsmith college for about a month, because I wanted to spend good time at that period. Goldsmith college was located near New Cross station and I stayed at dormitory of this college, because at summer time, dormitory was empty due to the summer vacation time. And I happened to watch Flickr yesterday and search the word "New Cross", then found Goldsmith College's & around this area's picture and felt longing for this town. New Cross is located about half an hour from central London by train, so it is very convenient place to go around central London. And this town is not so big (in another saying, feel a little deserted-looking), so I enjoyed the fist experience of abroad in a relaxing mode, so I liked this town very much. If you see this picture , you can see the dormitory(*) where I stayed about 20 years ago, so I am deeply moved. (*) UK's college is started at September, s

We went to Iga-ueno city to see Ninja show. Recently, my son likes ninja, and he practice how to make syuriken by origami-paper at kindergarden and Iga-ueno is the place where I wanted to go, so we went there at 21 July. It was about 1.5 hour by car and we arrived there about 1 p.m. and ate lunch at okonomiyaki shop " Ito ". This shop is like normal house, and we make okonomiyaki by ourself and we order big size okonomiyaki and big size yakisoba and cost 1230 yen ($12) and tasted very good ! After eating, we went to NINJA MUSEUM of Igaryu . And inside this museum, there hold Ninja show (needed extra cost 300 yen per person) and the last show started at 3 p.m. so we safely watched the last show. This show was very good and after watching this show, my son tried syuriken.  After this show, we walked through this museum and there were tour-guide so they navigate us and telling the story of ninja's life.

Our new family !

Image
He is our new family and he is our first baby! He was born on 28 May, and this Wednesday he came our home from hospital and 4 days had passed. He is very very bouncing baby so my wife couldn't sleep well, but we love him very much. He cried very loudly so we tried to ease him in various ways, and this picture is one of ways to be quiet. (this red material is a rattle and if I shake this rattle, he is very curious about it and hear this rattle's sound and sometimes stop crying!)
