The electricity I tested seems much less than I had paid for. I am gonna do an investigation. Including the water supply system. As I am no longer worried about my visa. A refrigerator is excluded. But the result is still problematic.

That's the difficulty of FSO communication. It needs high power to overcome the air absorption and refraction. Let's find how it works.

This is a 1kMbps optical fiber module. The light could travel 20 km inside the core. The optical power is extremely low(<5mW). This is exactly because it needs to be modulated at over 1GHz. The laser cavity needs to be held at threshold condition to follow that high frequency.

It moves 1.25um for every step along the z-axis. Here, it moved 100 steps.

Provider soldered the module, then I took the driver IC, and then I soldered it again. This could be the reason.

不登校ちゃん @betaradiation.bsky.social · 2d

Soldering is difficult. I used water to cool down the other two ICs to protect. Fortunately, this time, I used one driver IC, and then one succeeded. The modules I bought from Amazon are weird. I believe they are not unused.

Those days when I drank this milk, I felt chest discomfort and extreme fatigue. It might be caused by other problems. But my feelings told me it's it.

Japanese housewives manage that, they may not work for full 8 hrs*5 every week. That's all guess. The most direct way is starting to contact Japanese. As I have had another 5 yrs visa, I must do that, or I just look like an idiot living under a dark Japan.

Japanese usually shop once for one week supply. And they have cars. If one places don't have their wanted goods, they may easily go far away by driving. But I can't. More importantly, I can only buy food after 19:00, that was locked. I'm easily targeted.

This is not a good college. We just rented a few classrooms at this place.

不登校ちゃん @betaradiation.bsky.social · 5d

I didn't call now. The first reason is that I don't have enough evidence. I guess the police may push it away(at least in my living area). Even the police perform their duties conscientiously, evidence is required. I will need the medical report.

不登校ちゃん @betaradiation.bsky.social · 5d

I may not care about others. I will record myself. Because pity Chinese in China sometimes died in a state of bitterness and still don't know why. I will call police when necessary. Include playing dirty.

I still don't understand why I thought my teacher was staring at me on purpose. It's so coincidental that I later became CCP's target. I have always thought that I might have had mental issues at that time. My families contacted the head teacher more than two times. Now I doubt it for my experience.

Maybe that can be an experimental test for real poisoning. Anyway, I must have all predictions.

Here only need a shocking modern decoration but not advancement. Sometimes, we took ourselves too seriously.

不登校ちゃん @betaradiation.bsky.social · 5d

I need a bag for my important tools and knowledge results. Having a sense of crisis is important. Just like diarrhea is a sign of how many chemicals you have eaten. It can be a comparable indicator for real poisonous chemicals.

There're too many tools. I want to buy another table from local to arrange all this stuff. Exchange or buy something threw for almost 0 yen. I will not buy a new one because I don't know how long I can still stay here.

Picoscope 2208b mso has a logical analyzer. It can be controlled directly by Python interface. But its bandwidth is too low (100MHz), it's useless for my application (fpga&communication)

The brilliants expected people show a happy face to eat industrial chemicals. Logically, anything probably intrigued should be fully ascribed to them. Otherwise, when one got cough, I recommend this.

4 out of 10 eggs I bought from the supermarket are actually cracked. I didn't eat them.

An Olympus objective priced few thousand dollars. I bought it for only 60k yen(about 400 dollars). I handle it so carefully.

不登校ちゃん @betaradiation.bsky.social · 5d

I abandoned a USB Oscilloscope priced 185000 yen. And chose another maker. This one is priced 55000 yen. I indeed chose a good one but not the one with extreme high prices and worse performance. The balance decided.

Bear too long and then suddenly call police, report poisoning. This is somehow dangerous because it makes people think that it is normal and then all take it for granted. Even life, that's why it's so ridiculous, unscrupulous. It can also become an excuse. So, I prepared a timeline.

This is so good for arbitrary position controling of optical tweezers. Including generating multiple traps for multiple particles. As the trapping time is spared for every particle. Even 120Hz refreshing rate is enough.(120 times scaning every second)
