So today, I talked with one of senior manager  in my office.

 

I was only want to confirm about next week Application Outage due to F5 vulnerability Patching.

 

There are 3 applications, one of it is already have Multi-site High Availability configured. And so, we agreed to announce application outage for the other 2 in the next week.

 

Then, one of my colleague went out from a meeting room, located just next to the senior manager's table. I'm not sure what the meeting was about, but I could confirm it was about e-Procurement Application.

 

Then, he started to talk about my Japanese ex. I ended up spin up my dusty memory tape from my hearth.

 

I told to them about my past, on how I met her, how it get's ended, and what I may still struggle with till now.

 

Well, I'm 33 for now, and will be 34 next year. Time flies so fast.

 

The senior manager told me the story on how he met with his wife.

 

So, he is a typical hard worker like me. He understands that, those time back then were the time for him to actualise what he wants to be, of what he actually is. So he often works till the night, and didn't have time to sosialise.

 

He met with his wife in his 'kost'. He often met her while coming home from work at the night, when she was about to go out to have a dinner. He feels grateful he met her, because he believes, he is still single if that encounter didn't happen.

 

From that chit-chat, I can conclude that, maybe I still haven't open myself, yet. Or, I haven't open it as a whole.

 

How to be open? Only me know how to be open.

Work from home, boredom, and being at peace with yourself

 

 

During this corona epidemic, work from home is a regular thing. Maybe, it will be hard for some person, for example, the one who has kids in their home, and the one like me who live alone. No physical contact, every communication is done via the internet.

 

For a person like me, talk with people is an essential thing in everyday life. What will I get if I live the day without talking? And almost every day?

 

The first symptom was, bad temper. I became mad easily. The second symptom was, the feeling of not being loved. It feels like, no one wants to talk with me, despite this was because of the working situation. Then the last one, was eventually, loneliness. These attracted alcohol almost every night.

 

The key is to make yourself being at peace with yourself. The enemy resides in you, the feeling of loneliness, the feeling of uselessness, and so on. No one to blame.

 

I was an avid scale model hobbyist, mainly 1/32 aircraft model. So I resurrected that hobby out of me. I started to build 1/16 and 1/12 RC model. I also did some experiments to control the lights with a microcontroller. I slept at 2 AM almost every day, just tinkering on why the join between some parts are not aligned correctly, on why the code was not working correctly, on how to paint the model in the toilet so the neighbourhoods will not smell the paint, and so on.

 

This helped me a lot.

 

Being busy will make you forget those feelings, at least for a person like me.

 

 

The corona epidemic is still going on.

Today, it is informed officialy, my work from home is extended up until 22nd of May..

I watched the Always, Sunset on the 3rd Street series.

My Japanese friend recommended me these films. She is an undergraduate student. We are lost in contact... though she has had recommended me these series.

While I watching the movie, I'll write down every word that I want to learn. Thank you Yuriちゃん、though you were gone with no reason..

I watched the films. These films told me how the 'Old Japanese manner' is, as what I've had known, and I like that idea. The way the Japanese insist on their idea, up until they know the truth, the will apologize. Watching on how they are going through the post-war has amazed me. If only the war had not happened, two of the family woman and the family man might had not been living an integral life. 

The city keeps changing too throught the series.

In one scene, they are waiting for a film, and they lined up together to get in the cinema, how civilized it is, I like that. The momentum they had after the war, the momentum that every one in the country acknowledge, to build the elemental knowledge of how a civilized society should be. I wonder how Indonesia can do that..

The Binくん diary.

Was trying to use TB6612FNG.

 

I'm now in the process to create a trash bin robot, Binくん. I have bought all of the parts, waited for days, and eventually today, I can start the wiring process. It uses an H-Bridge to control 2 of its motors. I was wanted to use L298N, which is the common H-bridge used in the microcontroller world, but then I saw this video:

 

TB6612FNG.. sounds interesting, as it is very small and I don't have to build the diode circuit to tame the backfire voltage. So I searched for one and found it through the online marketplace. The store is in Surabaya, it took 3 days to arrive.

So, today, I tried to use it using the breadboard. It is a dual output H-bridge controller, and we can control the speed of each motor using PWM sockets, which is available for each output, according to this schematic diagram:

So I wired the breadboard, wrote some code to test it, and voila, It didn't work..

The motors run well, but I couldn't set the speed of each motor, It will only run at full speed. I tried to not use the common ground for, as I thought the chip alter the ground according to the PWM signal, but it didn't work either.

I was lost, as I really want to use this chip for the project. I've prepared my L298N and was about to dump the TB6612 chip, but then I take a look at the chip very carefully;

 

"DRV8833"

 What?!

I expected it to be a Toshiba TB6612 chip. Maybe that's why it says NC (Not Connected) on each of the supposed to be the PWM socket, which has assured me it couldn't receive the PWM signal.

Searched for the internet about the DRV8833 and I found out that it actually can receive PWM inputs, and it's not separated with the HIGH/LOW inputs as with the TB6612, but it's integrated with the AIN/BIN inputs, which is great! 

I rewired the wires and it needs 2 fewer GPIO outputs than before, as it doesn't need a separated HIGH/LOW signal and the PWM signal for each of the motor control, and it works very nice.

It is a good chip, effective, and small, but looking at its size, I don't know about its reliability. Well, let see how long this chip will last with me.

Yesterday was the second day of my work from home.

Due to the corona outbreak, I'll work from home until the end of the month.

It seems like it made me an anti-social person, staying in the room at the work hours, with no one to talk physically. I had upgraded my internet connection speed just for this occasion.

My parent came to my apartment yesterday, she brought food, a pan of delicious tuna chunks, stirred with tomatoes, chili, a lot of garlic, and chops of carrots. She also brought traditional drink which has a profound taste of cinnamon and ginger.

"Don't stay too long, I might be a carrier of corona", I said.
"Of course, your father will be worried if I stay too long, so I got to go fast, only to drop these for you"

She managed to gave me a back massage before she went home.

The tuna stir-fry brought my memory, back to when I was in the "kost". I used to cook that exact kind of cooking, easy, delicious, and nutritious. I really like its taste that comes from garlic, mixed with brine that comes with the tuna can.

So, 10 days to go, before I'll go back to work in the office. It may be getting worse, it may be extended, who knows.

Near the end of the work hours, I looked at the clock, it was 30 minutes to 5 in the evening. Of course, here in Indonesia, it is "Evening", though most parts in the world still regard it as the Afternoon. I sat down at the corner, next to the balcony door and laid may back to the toilet door, looking out to the sky. It was quite dark, though it was around 04:30 PM, the sky was covered with a thick layer of cloud, the rain would come soon.
I thought to go out to refresh my head, as I'm not really an introvert, nor an extrovert too. I don't like to be in the crowd, yet I don't like to be alone, I must have a person I have to talk with at least, every day.
So, I prepared to go out just when the rain had started to fall. I ended up locked in my room.
I opened my tablet, looking for a movie I hadn't watched. My brother had recommended me to watch a Korean movie which won the 2019 oscar, the Parasite. I had it downloaded a long time ago, but I had never had the appetite to watch it up until that time. It was such a great "comedy" movie. The way they plan to impersonate the characters they need to be was so systematic and well planned. I like this kind of movie, in which it is logical to happen in the real world. There might be some of those parasites living in rich family houses right now.

The drink my mother had brought to me made me sleepy. I thought it was good, and so I fell asleep fast. It will fix my biological clock. So I woke up at 4 AM, naturally, in this morning, writing this.

おはようございます。
