[Hydroponics] PVC pipe processing method! Make your own water circulation cultivation kit with laundry drain hose

We are going to try hydroponics using PVC pipes on one wall of the room.
We are planning to line up five or six PVC pipes horizontally on a wall about 230cm long and 320cm wide, and we have already made a frame to support the PVC pipes.
This time, we will actually process the PVC pipes.
To watch the video, click the link below.

Let’s take a look.

Cut the PVC pipe according to the wall surface.

Prepare the required number of PVC pipes.
Since the length of the room is about 230cm, I thought there would be 5-6 PVC pipes that could be installed considering the height of the vegetables, so I prepared 5 slightly weak PVC pipes.
If you know someone such as an equipment shop owner, you may be able to get some extra PVC pipes.
I got three from a friend of mine who works at an equipment store, and bought two from a material store.

How to mark a straight line on a PVC pipe

Before cutting the PVC pipe, it is easy to cut straight if you draw a line around the part to be cut, but drawing a straight line can actually be difficult.
Prepare a piece of paper large enough to go around the PVC pipe, and wrap it around the part you want to ink.
You can draw a straight line along the edge of the paper with a magic marker.

A pipe saw is recommended over a woodworking saw.

You can also use a wood saw to cut PVC pipes, but it will get stuck in the middle of cutting, making it difficult to continue cutting.
In this case, you can make it a little easier to cut the PVC pipe by turning it slightly toward or away from you.
The top one is a special pipe saw (for cutting pipes) and the bottom one is a wood saw, but you can see the difference in the fineness of the grain.
You can see the difference in the fineness of the blade. The pipe saw has a finer blade, so it can cut smoothly without getting stuck.
The PVC pipe used in this project is 10cm in diameter, which is quite thick, so I chose a pipe saw with a long blade of 30cm.


Processing the end cap for the PVC pipe

Drill a hole in the end cap that attaches to the drainage side of the PVC pipe.
If we drill a hole in the middle, the water level in the PVC pipe will be lower than half of the pipe, so we need to position the hole a little higher so that the water level will be exactly half of the pipe.
Place the actual drain valve against the end cap and mark the center of the hole.
If it is too high, the valve will hit the inside of the end cap when you turn the valve screw and you will not be able to turn it, so be moderate.
Place the tip of the drill blade on the mark and drill the hole with the hole saw.
In the photo above, I am holding the end cap with my foot, but to be honest, this is not a job to be done barefoot. It is usually dangerous.
It is better to fix the end cap in a vise or vice.
The following products can be used for products up to 150mm, so the 100mm end caps used in this project can be fixed securely.

I also ordered the above product, but it didn’t arrive at the time I was working on it, so I ended up fixing everything with my feet while working on it…pointless shopping.

Connecting the drain valve to the laundry drain hose

Now that we have finished drilling holes in the end caps, we can connect the drain valve and the drain hose.
Pull out the threaded part of the drain valve from the inside of the end cap, and attach the drain hose to the threaded part that came out.
The threaded part of the drainage valve was too long to adhere to the end cap even when it was tightly closed, so we cut the excessively long part with a pipe saw to make it adhere.

Make a hole for the seedling in the top of the PVC pipe.

Now that we have finished processing the end caps, we will drill holes in the PVC pipe body for the seedlings.

Measure the length of the crop roots.

If the spacing between the holes is too narrow, the roots of the crops may get tangled up with each other and water may not circulate properly, causing water leakage.
Before drilling holes at appropriate intervals, measure the length of the crop roots and drill holes in the PVC pipe according to the length of the roots.
The photo above is of lettuce, and the length of the roots is about 30 cm from the tip to the thin part, and the lettuce next to it and the small tomatoes at the back are also about 30 cm long.

Marking and drilling holes at equal intervals on the PVC pipe.

Mark 30cm, 60cm, 90cm, etc. from the end of the PVC pipe.
Drill the marked areas with a hole saw in the same way as for the end caps.
There is room for a water supply hole at the far end, so we were able to drill 9 holes in total.
When drilling holes, burrs inevitably appear, so I shaved them off with sandpaper.
This is for injury prevention and appearance.
Chips from cutting with the hole saw and sandpaper accumulate in the pipe, so we washed them away with water.
There was no faucet outside, so I asked a friend who had acquired a PVC pipe to install one for me.
A sprinkler would make it easier to work with water outside, thank you Yoshida.

Caulking the connections to prevent leaks.

We are almost done here, let’s work hard.
The unfinished end cap and PVC pipe, the finished end cap and PVC pipe, the drain valve and the drain hose part need to be caulked.
Let’s start with the drain valve and the drain hose part.
Apply metamorphic silicon to the inside of the cap, and connect the drain valve and the laundry drain hose.
After screwing them in tightly, mask the surface of the cap with masking tape and caulk it.
When you have finished applying the caulk, smooth it out with your fingers.
(Well, maybe you don’t have to use your fingers, but there is something special for that.
Remove the masking tape when you are done.
If you do not remove the tape after applying the caulk, the tape and silicone will stick to each other and become difficult to remove.
Follow the same procedure for other areas.
This is an important process to prevent water leakage.
If you don’t plan to dismantle the pipe in the future, you may want to use “PVC pipe bond”, but in my case, I didn’t use bond because I was thinking about reassembling the pipe and maintaining the clogged roots.
Good or bad…After caulking, I left it for 24 hours and the metamorphic silicon was dry.

I lined up the processed PVC pipes on the frame made for PVC pipes and completed the work.

I was tired after doing these processes for five PVC pipes, but I was able to do it.
These are lined up on a special stand to complete the project.
At the bottom (floor), we placed a kind of water storage tank, and installed a pump to pump water into it. Without the pumping pump, nothing can start.

We pump the water to the water supply port of the top PVC pipe.
When the water level exceeds half, water will flow from the drain hose on the other side.
The end of the drain hose is connected to the water supply port of the second PVC pipe, and when the water level of the second pipe reaches half, water will flow to the third and fourth levels.
The drain hose of the bottom PVC pipe flows to the water storage tank, and the water in the tank is sent to the top PVC pipe again.
I haven’t circulated the water yet because this is an introduction of how to process PVC pipes, but I think it’s probably okay…irresponsible.
Because of the depth of the frame, it is physically possible to put two or three PVC pipes on the same level.
It is possible, but there is a disadvantage that it might be troublesome to take care of the crops planted in the PVC pipes at the back, so I’m thinking of trying one PVC pipe per tier first.
This is how I processed the PVC pipe for hydroponics using a laundry drain hose.
I hope this will be helpful to someone else.








[Hydroponics] Assembling a frame to support multi-stage PVC pipes on the wall with a single pipe.

Using an entire wall indoors, we will try hydroponics using PVC pipes.
We are planning to line up five or six PVC pipes horizontally on a wall about 230cm long and 320cm wide, but considering the 300cm long PVC pipes, the water in them, and the weight of the vegetables, we need to build a rather solid frame.
This time, I was lucky (?). This time, I was lucky enough (?) to find some single-pipe pipes thrown around in the garden, so I processed them to make a box-shaped frame for the PVC pipe.To watch the video, click on the link below.

Here you go.

Cut the single-pipe pipes to fit the wall surface.

First, we need to prepare a single pipe.
The size of the wall in the room where we will be growing hydroponics is 230 cm long and 320 cm wide.
Therefore, we will need four 320cm monotubes for the horizontal, six 230cm monotubes for the vertical, including one in the middle for strength, and 15 short monotubes to support the PVC pipes.
At the moment, we’re thinking of installing one PVC pipe per tier, but since there’s a possibility of adding more pipes in the front, we’ll prepare longer single pipes for the sides so that we can expand them later.
Now let’s cut the single pipe.
I found an old-fashioned high-speed cutter in the work shed, so I’ll use this to cut it.
Later, I noticed that the blade of the cutter was so worn out that the diameter of the blade had become very small.
In this condition, it is impossible to cut a single pipe in one go, so I highly recommend replacing the blade with a new one before the work if you can.
Because you are cutting from the top and bottom (or because you are not very good at it), the cutting surface will be rickety.
If this happens, you will have to do a lot of extra work, such as removing burrs with a sander. I actually had to do this, and deburred a total of 25 pieces.
If you don’t have a high-speed cutter, you can also use a pipe cutter, although it is not suitable for mass cutting.

Also, if you bring in a single pipe, it is not possible, but if you buy a single pipe at a home center, they can cut it for you for a fee.
In my neighborhood home center, it was 200 yen per cut.

Put the fixed base on the cut single tube and stand it up.

Now that all the single-pipe pipes have been cut, we will carry them into the room.
First, fit the fixing base to the vertically extending single pipe.
Next, use the orthogonal clamps to temporarily fasten the shortened single-pipe to the vertical pipe, and raise the single-pipe in a “well” shape.
If the pipe is slanted, level it with a leveling tool, and then tighten it with a ratchet.
Make another set for the opposite side.

Use the orthogonal clamps to assemble the tubes into a box shape.

Next, let’s set up the long single pipe that extends horizontally.
I almost died when one of the tubes fell in my direction while I was working on it, because it was just standing on the wall.
It seems that you need to be very careful when you are working. If it had hit me on the head, it would have been pretty bad.
Even though I was dying, I assembled four horizontal single pipes.
If the center of the PVC pipe bends and breaks, it will cause a terrible situation, so we set up a single pipe in the center to support the center of the PVC pipe.
The next step is to assemble short single pipes for both sides according to the height of the PVC pipe.
When you actually put the PVC pipe on top, it is okay if the PVC pipe itself is level.
I put on a protective cap to prevent injury from the cut surface of the single pipe.
I don’t want to get hurt.

Circulating water with a pump

This completes the stand for PVC pipes using a single pipe.
In order to circulate the water in the PVC pipe, we need a water storage tank (or something like that) and a pump.

First, prepare a tank on the floor and fill it with water.
Use the pump to raise the water up to the top PVC pipe, and when the water in the PVC pipe exceeds a certain amount, discharge the water from the drain hose on the other side.
A drain hose for a washing machine is used for the drainage hose.
When the amount of water in the PVC pipe reaches a certain level, it is discharged from the opposite side and repeated for the third and fourth levels.
The water discharged from the bottom PVC pipe returns to the water storage tank, and the pumping pump raises the water to the top PVC pipe.
When the water in the tank runs out, the water cannot be raised, so watch the water level and refill the tank if it seems low.

More PVC pipes can be added depending on the length of the single pipes on both sides.

We can increase the number of PVC pipes that can be installed per tier by lengthening the short single pipes that we just installed on both sides.
However, since this is a hydroponic cultivation using the wall, I think the maximum number of PVC pipes that can be increased is about three, considering the harvest, care of the vegetables, and ease of lighting. This is just my imagination, though.
The length of the PVC pipe is 300cm this time.
If we assume one plant per 30cm, we can plant 30 plants per tier if we install 3 PVC pipes.
If we increase the number of tiers, we will be able to grow 60, 90, or 120 plants, which is a tremendous amount of vegetables indoors.
This time, we were not talking about how to process PVC pipes, but how to make a PVC pipe stand.
But if you want to make it on a smaller scale, you can use wood or Irector, which is much easier.

In any case, I hope this will be helpful to someone who is thinking of starting hydroponics.

How to use a Switch controller to control minecraft on mac. Setting public [Joystick Mapper].

I installed the mac version of minecraft, but… keyboard control is too difficult!
If you’re not used to playing computer games, it’s impossible to play the PC version of minecraft with a keyboard.
If you’ve installed minecraft on your mac without realizing it, you’re probably regretting it.
Don’t worry.
Use the Pro Controller (or Joy-Cons) for your Switch.

You can use a home console controller to control minecraft on your mac!
Please explain it in a video! If you want to learn how to do this, please go to

The following article will help you to record a video of playing with a pro-controller from a third person’s point of view, and watch a replay video.

Connecting the Switch controller to the mac via Bluetooth

First, let’s connect the controller to the mac via Bluetooth. It’s easy.
Setting up the controller
There is a small button at the top of the controller (near the charging port), press and hold it.
The way to do this will differ depending on the type of controller, so check it out as you go.
Bluetooth settings on the mac
Go to [System Preferences] > [Bluetooth] and click [Turn Bluetooth On].
If the controller is ready, the name of the controller connected via Bluetooth will appear in the [Device] field, and click on it.
If successful, [Connected] will be displayed.

Connected successfully! Okay, let’s get started with minecraft… but it doesn’t work…

That’s right. The world is not so easy.
You can’t control your mac with the controller just by connecting it via Bluetooth.
Let’s continue with the explanation.

Using mapping software to link controller buttons and keyboard [Joystick Mapper

The Bluetooth connection is successful, so it seems like it should work, but unfortunately it doesn’t.
In order to link the controller’s buttons to the keyboard, you will need something called mapping software.
In this case, we will use a software called “Joystick Mapper”.
Joystick Mapper

Unfortunately, there is a fee.
However, we can’t turn our backs on it to improve the usability.
Do you want to play minecraft comfortably with a controller on your mac?
Then buy it. Money is the answer.
In fact, as an amateur who played minecraft with a pro controller after using Joystick Mapper and mapping the settings as described below, I found that it was about 80% operability with the controller compared to 20% operability with the keyboard.
For more details on how to set up Joystick Mapper, please refer to “Joystick Mapper: How to Use a Mac with Joystick or Pro Controller”.
Anyway, it’s totally different. It’s a totally different experience.


How to use the Joystick Mapper to control a mac with a joystick or pro controller.

I’ve given it a lot of thought, and I’ll post the settings that I think are best at this point.
After connecting your mac to the controller via Bluetooth, use Joystick Mapper to configure the settings as shown in the table below.
Please do not change the control settings in minecraft.

In the above figure, after clicking [scan], press one button on the controller, and the button information (Hat, #0, Down, etc.) will be detected automatically.
Change the [keyboard key] part and the [Q] part as shown in the table below.
In this setting, buttons that are not used by the controller are not registered.
[(scan) / controller control / automatic / automatic / change as needed / change (minecraft movement) ] The view will be as shown above.

Differences between minecraft for nintendo switch and the controls

If you set it up in Joystick Mapper, 80% of the operations will be the same.
However, there will be some discomfort (about 20%).
The following is an explanation of the 20% of discomfort.
Cursor operations in the menu screen and item screen
You use the right stick to control the cursor in the menu screen and item screen.
The left stick is unresponsive.
Deciding and Returning in Menu and Item Screens
To make a decision, use [ZR (Main click)] instead of the [A] button.
To return to the play screen from the menu screen, or to close the item screen, press [Y (Escape)] instead of [B].

Once you get used to this, you will be able to play minecraft quite comfortably.
Now, use the Switch controller and have a fun minecraft life on your mac!



How to take hand-held videos|How to fix your phone at any angle and shoot from your eyes

This course explains how to film your hands from your own perspective while having both hands free, such as working on a desk, streaming sound games, cooking videos, etc.
You can shoot from above, hold your phone at any angle, or master eye-level shooting.
There is no trick to mastering it.
Just buy one. Money is the answer.

How to shoot without shaking with a tablet arm.

Trying to shoot with a phone in your hand will never work for eye-level shooting.
If you want to shoot good hand-held video, a tablet (monitor) arm is a must.


I bought the following product, and I recommend it because it doesn’t wobble at all.

I bought the following product, and I recommend it because it doesn’t wobble at all. The cheap ones with a squishy bendable arm have a weak grip, or the arm is too weak to withstand the weight of the phone.
I recommend you to buy an arm that is about the price of the product link above, as it can hold your phone firmly.
If you are considering buying an arm for handheld photography, you might want to buy one with a ring light.
If you are considering buying an arm for handheld photography, you might want to buy one with a ring light. .
I bought one with a ring light, which was mainly for the purpose of “watching my iPad while lying down! I’m just using it to take handheld photos of products whose main purpose is “I can look at my iPad while lying down!
If you’re going to shoot hand-held, it’s definitely better to have lighting than not, so I’d consider buying one with a solid arm and a ring light.
There is also a similar product, a tripod type stand, but if you are filming work on a table, the legs of the tripod will show up in the video if you are not careful, so you need to be careful when choosing one.

Actual video shot using the tablet arm

I tried writing with the tablet arm. The picture is taken from directly above.

Whether my handwriting is good or not, the video itself is well shot without blurring.
It is possible to film while looking directly at the paper and pen with your eyes.
As I mentioned earlier, the video seems a little dark, so an arm with a ring light would be better.
In this video, I gripped the arm on the side of the table and brought the phone to my eye level to hold it in place.
You can use the arm on the side or on top of the table as long as you can grip it.
If you want to shoot a wider area like a cooking video, you can fix the phone on a cupboard or something and shoot from above.

How to adjust the angle by moving the movable part of the tablet stand

The fixing method is quite simple.


Place the base of the tablet stand on the edge of the table, and turn the bottom screw to fix it in place.
The part of the stand that directly touches the table is covered with rubber, so it won’t scratch the table.


It is now fixed as shown in the photo above.
This tablet arm has four joints, so you can bend and rotate it to bring the head part to the position you want.
So, by setting the arm to the side, you can bring the camera right above you while dodging your hands.


I set up the tablet arm on the side and moved the phone right above the keyboard.


In this way, you can shoot videos using both hands from your own perspective.
Situations where using the arm stand is useful
Cooking videos
Drawing videos
Writing videos
Typing speed videos
Videos on Sound Games (Bandori, etc.)
Clay animation videos

A remote shutter to remotely control the shooting button is useful.

If you have adjusted your phone with the arm so that it is at your eye level, but when you tap the shoot button, it would be uncomfortable to have your phone out of alignment, so a remote shutter for your phone would be useful.
I bought this one.

You can usually buy them at 100-yen stores these days.
If you connect it to your phone via Bluetooth, you can tap the button on your phone remotely without having to tap it directly.

If you want to shoot with your hands, you’ll need an arm system that can hold your phone.

When I first wrote this article, I was recommending a tablet arm, but I think an arm with a ring light would be better if the main focus is on “photography”.
It’s not a tripod type, but a type that can be fixed to a table, etc.
If you are considering using an arm with a ring light for live online shopping or makeup videos, I recommend you to use it.

How to connect your phone to the car navigation system and watch videos in the car. amazon prime video will satisfy your kids!

People who are worried about how to pass the time while traveling by car.
I want to watch videos using my car navigation system, but DVDs are expensive and it’s a hassle to return them.
I’m worried about the amount of traffic on youtube.
I have an old car, but I wonder if I can connect my smartphone to the car navigation system to watch videos…?

This is the solution to these problems.
This article is for people whose car navigation systems do not have hdmi input or only have composite (red, white, yellow or RCA) connectors.

If you have a recent car, it may have an hdmi input terminal, but I’m sure there are many people who don’t have such a terminal.
I am one of them.
With a little initial investment, you can watch a wide variety of video content on your car navigation system through your smartphone, even in such an old car.
Renting DVDs is expensive, and returning them is a hassle…
I’m a little concerned about the amount of traffic when watching youtube…
But then again, pocket wifi seems to be too expensive…
It may cost a little bit of money, but let’s find a good compromise and have a comfortable car navigation and smartphone life.
If you are an AMAPLAC member, you can also do this.

If you want to connect your smartphone to your car navigation system and watch videos, the only option is Amazon Prime.

If you are thinking of connecting your phone to your car navigation system to use a video streaming service, the only option is Amazon Prime.
Prime members can watch all the Prime videos they want.
It’s a bit tricky to say, but Amazon Prime allows you to slip through the HDCP system, which prevents unauthorized copying of videos.
I’ll explain later how to connect the car navigation system to the smartphone, but I can’t actually play netflix, hulu, etc. when I try to watch them using smartphone apps.
I can open the app itself, but even if I tap play, the video doesn’t start.
If you can afford it, there are plenty of ways to watch videos in the car, but
But you don’t want to pay a lot! So I’m willing to compromise to some extent.
There must be a lot of people who don’t want to spend a lot of money to watch videos in their car navigation system, so if this applies to you, keep reading.
If you are one of those people, please read on. The video streaming service you should choose is Amazon Prime (where you can also watch Blade of the Demise).
You can watch Crayon Shin-chan!

Necessary preparations for projecting videos from your smartphone onto a car navigation system

You will need three items to project your phone’s video on the car navigation system.
Required equipment
Smartphone (iphone, android, ipad, etc.)
Smartphone → hdmi conversion adapter
hdmi → analog conversion adapter
In order to connect your phone to the composite input jack, two steps of conversion are required. 1.
1. smartphone (iphone, android, ipad, etc.)
Naturally, it is necessary.
Install a video app (Prime Video in this case).
Since there is basically no wifi in the car, download the video you want to watch to your phone in advance.
Download the videos you want to watch beforehand.
I have an old smartphone that I used to use, can I use it?
If you have one, you can use it.
You can use your current phone or your old phone in the car as long as you use your home wifi to download the video.
In my case, I’m using my unused iphone 5s for the car.
2. smartphone → hdmi conversion adapter
As the first step, convert the video downloaded to your smartphone (iphone, android, ipad) to hdmi.
Type of connection terminal of the device
usb type-c
The type of terminal varies depending on the device you are using, so be careful when preparing the conversion adapter.
In the case of lighting

I still have an iPhone 7 with a lighting terminal, but it works fine.
For usb type-c
For microusb

There are so many similar products, I don’t know which one to choose…

There are so many similar products out there, I don’t know which one to choose.

I happened to get the right one, but there are some people who get the wrong one, Chinese products.
If you don’t want to lose money on a cheap product, it’s a good idea to invest in a genuine product. If you don’t want to lose money on a cheap product, you may want to choose a genuine product or a product from a reliable manufacturer.
If you don’t want to get a bad product on Amazon, you can read about how to check for fake reviews on Amazon (the first step to avoid shopping mistakes), if you’re interested.

The point is, how much money can you afford to spend?
3. hdmi to analog conversion adapter
The second step is to convert the converted hdmi to analog (red, white, and yellow, called composite, rca, etc.).

Again, I’ve had success with this method.
After using two conversion adapters, the video from my phone was finally converted to an analog signal.
Now I can finally connect to the red, white, and yellow car navigation input terminals.

Two adapters and cables, isn’t it going to be a mess in the car?

Yes, it will. It will.
It’s the price you pay for not spending too much money.
Use your ingenuity and ingenuity to get over it.
The above items are a must as an initial investment for displaying smartphone videos on your car navigation system.
Read the reviews carefully and get one to avoid disappointment.

The specific amount of money I saved by using Amazon Prime in my car.

As a result of switching my viewing method to Amazon Prime, I was able to save money related to watching videos in my car navigation system, which I recommend.
It would be about 38,000 yen per year.
If you rent DVDs
We used to rent about 10 DVDs every Sunday so that we would not be bored in the car (since we have small children).
We would go through the 10 DVDs we rented in a week.
Sometimes the kids would choose their own DVDs, so we would end up renting the same DVDs.
Assuming it was an old movie rental, 100 yen per movie x 10 movies = 1,000 yen.
That’s 4,000 yen a month, or 48,000 yen a year.
And the risk is…
I thought I was renting old movies, but I found two new ones mixed in!
I forgot to return the DVD!
Going to the store and returning the DVDs is a hassle to begin with!
These are just a few examples.
Forgetting to return a DVD is especially mentally painful. You need to be careful because you will become poor for forgetting to return it.
If you watch youtube endlessly
As you can imagine, you will die.
Your communication volume will be half of what it used to be, or you will have communication restrictions.
It’s not practical.
If you use a pocket wifi
You can use it for around 4,000 yen/month.
This is enough to watch youtube without much problem, but the monthly fee is too high.
Pocket wifi has a fixed contract period, so you have to continue using it for 2 or 3 years.
If you cancel the contract in the middle, there is a possibility of penalty.
If you have to put up with a TV
In our house…

Dad, TV is boring! Boring, boring, boring!

And that’s for sure.
How much money did I save by joining Amazon Prime?
If you become a Prime member, you can watch all the Prime videos you want.
As you can see in the banner above, there is also a 30-day free trial.
Amazon Prime Membership Price
Monthly payment → 408 yen / month
Annual payment → 4,900 yen/year
In addition to that, assuming you have the necessary adapters as an initial investment as I mentioned earlier, the annual cost is around 10,000 yen.
If you convert it to a month, you can enjoy Prime Video for about 840 yen.
After the second year, the initial investment is not required, so you can watch Prime Video on your car navigation system for only 408 yen per month.
In my case, let’s compare just the first year.
480 DVDs/year: 48,000 yen – 1 year of Prime Video (including initial investment): 10,000 yen = 38,000 yen savings
Pocket wifi / 48,000 yen per year – 1 year of Prime Video (including initial investment) 10,000 yen = 38,000 yen saved
TV / 0 yen per year – 1 year of Prime Video (including initial investment) 10,000 yen = 10,000 yen over
Compared to TV, it’s not as free, but compared to DVD rental and pocket wifi use, it’s calculated to save 38,000 yen per year by accident.
Again, if you’re on a budget, you don’t have to do all these little things.

Benefits of becoming an amazon prime member

An amazon prime membership does indeed cost a monthly fee, but there is no such thing as a disadvantage.
Free shipping, free express delivery, etc., which makes everyday online shopping more convenient.
You can read books for free using your Kindle, such as prime reading.
Enjoy free music using prime music, …
There are so many benefits that I can’t even begin to explain them here.
If you don’t have time to read, you can read by ear.
If you are a Prime member, you can watch all the Prime videos you want, but if you combine your kindle with Prime Reading, you can “read by ear” in your spare time.
If you are interested, please visit [Don’t have time? If you’re interested in this, please check out “Reading by ear in your spare time by having your phone read out loud to you” (How to make the most of your time).
So much for my digression.
It’s true that compared to netflix, hulu, and youtube, the variety of content available on prime video is small. That’s for sure.
However, it’s unrivaled in terms of the overwhelmingly good price that makes up for it.
If you are in the same situation as me, please consider these methods.

[OBS] If you can’t hear the game sound, adjust the audio monitoring instead of the desktop audio.

The volume of the game seems to be kind of low, so I try to increase the volume using the desktop audio of the mixer… Oh, the volume doesn’t change. Why not?

I can get the game sound to come out of my computer.
There is a slider that seems to be able to adjust the game volume, but even if I move the volume slider of the desktop audio left or right, I cannot change the game volume.

I’ll show you how to make the sound louder or quieter with the volume slider in the [Mixer].

It cannot be adjusted in the desktop audio. Settings from the properties of the video capture device


The sound continues to play at a constant volume from the computer even if I try to move the desktop audio slider in the [Mixer] to the left or right, or set it to zero.
It would be easier if you could adjust the game volume you hear in the red circle.

To adjust the volume with the slider, first select【Video Capture Device】in【Source】and click on the gear icon (or right-click on the name of the video capture device and select【Properties】).

In this example, we have changed the name of the video capture device to Switch, so select Switch and click the gear icon.
Open the properties of the video capture device (compatible with your game console).

Change the audio output mode in the video properties to [Capture audio only].

The [Audio Output Mode] should be set to [Desktop Audio Output (WaveOut)] and the [Audio Device] should be set to your capture board.


Do not change the [Audio Device] setting at the bottom.
Change the [Audio Output Mode] from [Desktop Audio Output (WaveOut)] to [Capture Audio Only].

Oh, I can’t hear the sound anymore…
Yes, once you change [Desktop Audio Output (WaveOut)] to [Capture Audio Only], you will no longer hear any sound from your computer.


I moved the slider for [Desktop Audio] in [Mixer] all the way to the right, but the volume meter did not move.
Instead, the volume gauge of the switch that is the video capture device started to move.
Change [Desktop Audio Output (WaveOut)] to [Capture Audio Only].

In the Advanced Audio Properties, change Audio Monitoring to [Monitor and Output

Next, click on the gear icon in any of the [Mixer], and open the [Audio Advanced Properties].


The [Audio Monitoring] of the video capture device (switch in this case) that supports the game console is set to [Monitor Off], so change it to [Monitor and Output].

Did you hear the sound of the game from the computer again?


The volume meters for all switches, desktop audio, and microphones in the [Mixer] are working.

The volume output from the computer can be adjusted by moving the volume slider of the switch (video capture device) left or right.

Moving the [Desktop Audio] slider did not allow me to adjust the volume from the computer.
If you change the settings above, you can adjust the volume of the computer with the mixer knob of the video capture device linked to the game console.
Change [Audio Monitoring] from [Monitor Off] to [Monitor and Output].

Only you want to hear the sound of the game. If you do not want to output the sound to a recording or distribution destination

Well, I don’t think there are many situations like that, but I’ll explain how to do it.

I just changed the [Audio Monitoring] corresponding to the game console from [Monitor Off] to [Monitor and Output] in the [Advanced Audio Properties].

For special situations where you don’t want your viewers to hear the game sound, select [Monitor only (output muted)] for [Audio Monitoring].

Then slide the desktop audio knob in the [Mixer] of the OBS main window to the left (to set the volume to zero).

Also, if the default microphone device built into your computer is still functioning, it will pick up the sound coming from your computer, so slide the [Microphone] knob in the [Mixer] to the left and set it to zero as well.
With the above settings, you can create a situation where only you can hear the sound, the audience cannot hear the sound, and no sound is left on the recording.

To try it out, let’s try recording while playing a game and shouting.
Change the setting from [Monitor and Output] to [Monitor only (output is muted)].

Supplemental noise
When you watch the recorded video, you may find that some microphones have noises or daily life sounds (such as a whirring sound) mixed in.
You can reduce the noise to some extent by using the audio filter function that is available from the beginning in OBS, so you might want to try it if you are worried about the environmental noise in your video.

The difference between “monitor and output” and “monitor only (output muted)

If you want to stream or record at the game volume you can hear, select [Monitor and Output].
By adjusting the volume slider that is tied to the game console, you can adjust the volume for both the distributor and the viewer (or recording) at once.

Otherwise, if you want to keep your own volume constant and use the slider to adjust the volume of the viewer (or recording), select [Monitor only (output muted)].

In this case, you can adjust the volume on the viewer’s (or recording’s) side by moving the slider of [Desktop Audio] in [Mixer].

[OBS] No game sound! Change desktop audio settings and it will come on!

When you have connected the capture board to the game console and monitor, and are about to transfer the game screen using OBS, you may run into a problem where you cannot hear the game sound.
The answer is to change the “Audio Output Mode” to “Desktop Audio (WaveOut)”.
Let’s take a look at the specifics.

Change the audio output mode to Desktop Audio (WaveOut)

We will configure the settings to output game sounds from the computer.


From within [Source], click the gear icon of the game console from which you want to output sound (in the case of the photo, the “Switch” is connected) to open the properties window of the video capture device.


Scroll down to [Audio Output Mode] and change it to [Desktop Audio Output (WaveOut)] since [Capture Audio Only] is selected as the default setting.
Now you are ready to output game sounds from your computer.

Change the input destination of the game sound to the capture board.

Change the settings so that the output destination for the sound from the game console is the capture board.


After changing the audio output mode to [Desktop Audio Output (WaveOut)], check the [Use custom audio device] checkbox.
After checking the box, the item 【Voice Device】 will appear.
The default setting for the audio device may be [Microphone Device], but change this to the capture board connected to the game console (in the case of the photo, [Digital Audio Interface [MiraBox Video Capture]]).

Did the game sound come out of your computer?

If you set the audio output mode and audio device as above, you can get the game sound from the speakers of your computer, and if you plug in earphones, you can also hear the game sound through the earphones.

Steps to take if you get game sound from your computer but it causes feedback

I know I should have said this before, but if you follow the above steps to make game sounds from your computer, you will surely get feedback (the sound gets louder and louder).
The correct procedure to avoid feedback is as follows
Check [Use custom audio device].
Select a capture board from [Audio Device].
Change [Audio Output Mode] to [Desktop Audio Output (Waveout)].
Leave the audio output mode at the default setting of [Capture Audio Drink], change the audio device, and finally change it to [Desktop Audio Output (WaveOut)] to avoid feedback.


Now that the settings are complete, let’s take a look at the [Mixer] in the main OBS window.
The level meter for [Desktop Audio], which was not swinging earlier, now moves in conjunction with the game sound.

How to adjust the volume of the game coming out of the computer using the volume slider of the desktop audio

If you can adjust the volume of the game sound coming out of your computer speakers by moving the volume slider of the desktop audio, it would be easier to do something.
You cannot adjust the volume of the game sound with the slider without making various settings.
You can also learn how to adjust the volume coming out of your PC with the OBS volume slider, if you are interested.

Why I can’t hear the game sound even though the microphone volume meter is working?

The reason why you can’t hear the sound of the game no matter how much you turn up the volume, even though the level meter on the [microphone] is moving, is because the microphone is just picking up the ambient sound (life sound).
This is because the microphone is only picking up the ambient sound, not the game sound.


Microphones are picking up environmental sounds and the levels are swinging

Let’s find out which microphones are picking up what sounds.


I clicked on the gear icon in the bottom right corner of [Microphone] and opened the properties, and found that the device was set to
The device was set to [Default].
Find out what the default microphone device is.
Let’s find out what the default microphone device is.
Go to [Start] -> [Control Panel] -> [Sound] -> [Recording] tab, and you will find several types of microphone devices.


The second [High Definition Audio device] from the top is the default microphone device.
The reason why the microphone meter was moving was because the computer’s built-in microphone was set as the default microphone, and that built-in microphone was picking up ambient sound.
Examples of ambient sounds
My voice
The sound of the TV in the living room
Environmental sounds such as typing on the keyboard

[OBS Studio] How to project yourself with multiple cameras, including in-camera and webcam.

After you have downloaded and installed OBS, and finished the initial settings such as the theme and language of the main screen, use an in-camera or web camera to actually project yourself on the screen.
Use a video capture device.

Select a video capture device and project it with the camera.

Click on the “+” mark below the source to select the video capture device.



Click OK to create a new device. The device name is initially [Video Capture Device], but you can change it later.

Using the built-in camera of your computer


The above picture shows the properties screen of the video capture device.
If your computer has a built-in camera, the name of the built-in camera will be displayed in the device field.
In my case, USB 2.0 Camera is the built-in camera name, so I left it as it is.



The OBS window will show your reflection in the in-camera image of your computer.

You can move the in-camera image freely by dragging the image, and you can zoom in and out by dragging the eight red dots.

We will change the name of the video capture device to in-camera to make it easier to understand later.

You can change the name by right-clicking on the video capture device ⇒ Rename.

Using an external web camera

If you have another external web camera, try to connect it at the same time.


Connect the webcam to the USB port of your computer and go to “+” ⇒ Video Capture Device as before, and select the name of the connected webcam in the device field.
We have connected a web camera named HD Webcam eMeet C960.



The web camera image will appear as shown on the screen. It is placed on the left side of the computer.


After clicking OK, the web camera image will appear in the main window. I named it “External Webcam” as I saw fit.
In my case, only the video from the external web camera was choppy for some reason. If you are experiencing the same problem, please check out how you can improve the choppy video.

Project multiple images like a wipe screen.

In addition to the basic large screen that you often see in videos and TV, there is also a small screen, right? This is the wipe, the small screen that shows the face of a celebrity or distributor.
Wipe screens can also be easily arranged.


The in-camera is now hidden, but you can check both images by placing it in front of the external webcam image.
With the in-camera selected, click the upward-pointing △ next to the gear icon below the source.


This will change the order of the sources, placing the in-camera at the front and the webcam behind it.
You can zoom in and out and move around in the same way.


With the Nintendo DS connected and the capture device name set to Switch, three screens are shown simultaneously.
In the source order, the higher up you go, the more the images are placed in the front. The image of the switch is placed at the far end of the screen.
By the way, you will need a separate capture board to project the game screen.

Now you can see the in-camera, external web camera, and game console images in the window. Next, let’s try playing the sound.
The volume gauge is working, but for some reason you can’t hear the sound even if you turn up the volume on the computer itself, so try to make sound from the computer running OBS.


[Fire TV Stick Initial Settings] Restarting the device will solve the problem of no sound or no display.

fire tvを挿す

When you connect your fire tv stick to a TV for the first time, you may find that the screen does not show up or the sound does not come out.
Here is a brief explanation of how I solved the problem of no screen and no sound.

If nothing appears on the TV, unplug it once.

If nothing appears after a while after connecting to the TV, try unplugging the power supply plug once.

fire tv stickを接続してもテレビに何も表示されない時は一度電源プラグを抜く

As you can see in the picture, there is a USB cable extending from the main body of the fire stick that plugs into the wall socket, so unplug it, wait about 10 seconds, and plug it back in.
Unplug it, wait for about 10 seconds, and plug it back in. If you see the “amazon” logo, you’ve succeeded.
I was happy that it worked, but then the TV went dark again.

If unplugging and plugging in the power supply doesn’t work, move the HDMI port slightly.

If the problem is not solved by unplugging the power plug, it may be a physical problem with the connection between the TV and the fire stick.
Unplug the fire stick from the TV and plug it back in.
Also, if you move the connection part up and down, left and right, back and forth, etc., just a little bit (just a little bit so as not to break it), it will connect properly and you will be able to see it on the TV.
Although the video output stumbled during the initial connection, I have been using it for about two years now and have not had any problems with it not working again.


If you connect the TV and fire tv stick itself directly to the TV, it is easy to break when people or objects bump into it, so you can use the extension cable that comes with it.

If there is no sound, reboot the fire stick.

If things are going well, you can hear the “beep” sound when you move the cursor on the menu screen.
In my case, however, I was so busy with the initial setup that I didn’t notice the lack of sound until I was actually watching a movie.
If you see the image but no sound, reboot the Firestick.
Use the remote control to go to [Home], [Settings], [Device], and then go to [Reboot] to reboot the fire stick itself.
You will be able to hear the sound after the reboot.

Selecting the dolby digital output didn’t produce sound after all.

There was no sound, and when I checked various sites, I found something about [dolby digital output].
I’m sure you can get sound by rebooting, but in case you can’t fix it by rebooting, here’s another way to fix it (I couldn’t fix it this way)
Go to Home→Settings→Display and Sound→Audio
Using the same remote control, go to [Home] -> [Settings] -> [Display & Sound] -> [Audio].


There is a “dolby digital out” option, so you can select that (although I didn’t).
You will get sound one way or the other.

Initial settings for the fire tv stick (just in case)

If you can see the image on the TV and hear the sound, you are probably done with the initial setup, but just in case, here is the explanation.

fire tv stickの初期設定(念のために)

There is a language selection, choose Japanese.

fire tv stickの初期設定(念のために)

When you get to the screen to connect to the network, select the wi-fi that you use at home.

fire tv stickの初期設定(念のために)

Enter the wi-fi password (it’s written on the back of the router or something)

fire tv stickの初期設定(念のために)

We’re connected.

fire tv stickの初期設定(念のために)

Set the functional restrictions and download the necessary applications.
You can change these settings later, and use functional restrictions as needed.

Can’t I control the volume with the remote control of the Fire Stick?

As it turns out, you can’t adjust the volume with the old fire tv stick (1st generation) remote.
There are products that can adjust the volume for first generation remotes, but they cost over 10,000 yen, so I don’t recommend them at all.
The newest fire tv stick is only about 5,000 yen and has a volume control function on the remote.
Adjusting the volume on the TV remote is a pain in the ass! I want to do it with the fire tv stick remote! If you want to use the fire stick remote control, you should buy a new model.


If you are confused about video apps, Amazon Prime Video is fine for now.

There are many video streaming services such as Netflix, hulu, and Amapla, but if you want to use the download function and watch them on your car navigation system, Amazon Prime is the way to go.
With Netflix and hulu, you can’t watch downloaded movies in the car due to the hdcp (copy protection).
However, if you use Amazon Prime Video, you can watch videos in the car without wi-fi.
The free trial period is set at 30 days, so if you want to stop using it, you can just cancel it.
This is the solution to the problem I had when I initially set up my fire tv stick.
