In this case you will have to download the script and install the application in the Root or General User. There are many paid applications that are available, and I'm sure this one is well done.
Installing with ssh
Libre PCB oct 2020
$ sudo apt-get update
$ sudo apt-get install kicad
Raspberrypi digital out without HAT
Raspberrypi does not have audio analog out .because originally pwm out then low passfiler by active filter IC ,then get Audio.please see nex URL
Circuit Editor for Linux by Kicad is best
You can use Qtbsch for x86, but these applications are not available for Arm processor PC .so have to choose the other side of application.
Kicad is good for raaspberrypi work station. Kicad is family of KDE and Plasma so have to install plasma desktop into Raspbian.
$ sudo apt-get update
$ sudo apt-get install kicad
that's all.and you can use by Raspbian

Select your DAC from Overlay
For Raspberry pi, you can select the I2S DAC by editing /boot/config.txt. The driver is in /boot/overlays/ and you can use your DAC by editing the config.txt file.
You can use Nano or Emacs to edit them. In my case, I use Moodeaudio, which looks like this
pi@moode:/boot $ cat config.txt
Hifiberry is expensive in Japan, so I use justboom-digi, and the DAC is a homemade 198Khz 24-bit DAC. I'm very happy with the sound.

Circuit diagram creation application for Raspberrypi 4 Raspian
I tried using various applications for ARM, but all of them are difficult to use, isn't it easier to use? There are quite a few digital circuits, but I don't have a library of vacuum tubes. For X86, Qtbsh, Calduas, etc. are very good, but
On ARM, these applications can't be compiled, I think Kicad is good, but it's complicated, so let's use Inkscape here. I think it's very good. The library contains the parts of the schematic made with Qtbsch, which are commonly introduced.
I will use it. Since these can be saved as png originally, make a lot of parts library of PNG file. Cut out the schematic parts and save them with a PNG extension. After that, I will create it with Inkscape. It lacks the freedom of QtBsch,
Well, there is nothing that can't be used. Save the library as SVG or PNG. The save directory is under .config /inkscape /symbol.
Circuit diagram drawn with Inkscape h5>
For LibreCAD Arm
KiCad is complicated to create components, and even if components are created, detailed settings cannot be made. Basically, since it is CAD for PCB, I think that there is no freedom to create a circuit diagram. I think Inkscape is easier to use.
The component still needs to be crafted with other image editing CAD. There is a drawback that it cannot be saved as a part. There is no better CAD than QtBsch, but since Wine cannot be used on ARM PCs, it is an application for Windows.
cannot be used. Let's use LibreCAD. You can install it with $ sudo apt-get.
For Linux, copy the system library into the home directory. It will be .config /inkscape /~. The library opens commonly used schematics in GIMP and displays them in Inkscape.
Make a copy of the library from the schematic. The extension at that time is SVG. If you copy the symbol of the part into the symbol set, it becomes a library of electrical parts. Then draw a schematic using Inkscape
I will go. There are problems such as how to draw lines, but I think it is a usable tool. Once written, save it as SVG or export it as PNG.
The Tool closest to Qtbsch was found.
$ sudo apt-get update && apt-get install geda pcb gerbv
In other words, there was a gschema. It is a circuit diagram Editor that I did not notice after installing it before. You can edit the library lightly, and the lines are easy to stick, so it is a circuit creation editor just like Qtbsch. Lighter than anything else
Also, it is said that you can edit for PCB creation. I think you should make a lot of libraries. I think it is very good that straight lines are easy to draw.
It's basically GEDA. I think it's very light.
qcad is light.
No matter what you use, it's heavy and you can't get a straight line. Even if you can draw a straight line, the line doesn't connect. It's the same that the parts and the straight line don't connect. Kicad is complicated, it doesn't draw lines well, and it doesn't have individual parts.
I can't draw acorn-shaped vacuum tubes or circles clearly, the library is too complicated to enrich the library. In such a case, I easily lose to Qtbsch, and it is difficult to write on an ARM PC. LibreCAD and Qcad are very similar.
But I think Qcad, which has a lot of libraries, is good. The library can be created with Inkscape. If you're writing on an ARM PC, I think it's better to install 64-bit (formerly XP or Windows 7 PC) Linux on an older Intel PC and then install Qtbsch.
Qcad can be installed with $ sudo apt-get install, so please install LibreCAD and use it properly. I think Qcad is light.
Start drawing Qcad tube schematics
Editing with gEDA Circuit diagram creation
It is a circuit diagram creation by gEDA. This application is the lightest, but it is very difficult to write because I am used to Qtbsch, but I was able to create a circuit diagram. It was like this when I started using Qtbsch. The sym file is the part. The part creation application
No, so copy the base and delete it to make a new part. The attached parts are large and will protrude from the circuit diagram, so reduce the size to less than half and make the parts. First, open the file manager at the root and click on his sym file to open gschem.
There is an original part, so first delete it, leaving only the name. After that, I will patiently make parts. Save the most frequently used parts together in the tube amplifier parts folder (pseudonym). Close the root file manager and start from the beginning
I will draw a circuit diagram using the created parts. You can also draw a circuit diagram on an ARM PC, that is, Rasbian. I think that only long-suffering people can do it. I will make small parts when I have free time. The parts are
In my case, I saved the vacuum tube library in /usr/share/gEDA / tube. I don't think I'll use it because it's difficult to use, but I tried it.daefaults is black backside so can replace to white paper.
Not only Arm, but also foreign schematic editors are useless. If you want to write schematics in Linux, you need to use Qtbsch.
If you want to draw schematics on Linux, please install QtBsch on your x86 PC and draw schematics on it. If you want to draw schematics on Linux, you should install QtBsch on your x86 PC. It can't be used in applications that can't draw straight lines and intersections accurately.
I can't use it in my applications.
Rechallenge Pi-Zero W Music Server.
This PI-Zero is an Arm6, so it is slow and lacks a LAN port.
This PI-Zero is an Arm6, so it's slow and doesn't have a LAN port, so I need to add a LAN port to use it.
If you want to use it as a music server, you still need a LAN for the speed setting.
The Nanipi-Neo2 is much easier to use, but there are very few operating systems that can be used with this PC board, such as Armbian or Dietpi.
If you want to use it as a music server or for other experiments, you should use Pi3+B or higher version.
If you are looking for a music server or other experiments, please choose Pi3+B or higher version of Raspberrypi. We have found that small one-board PCs are very difficult to use.

Using Rune audio in the background using as Archilinux Music Server.
This is Runeaudio, a 3rd party version that is very heavy and the menus are not very detailed, but it uses Addons and Cantata to serve as a music server.
It's not so much that it's difficult to build, but that the menus are not very detailed, so you need to be familiar with the normal RuneAudio to get it to work properly.
So I use Cantata and SKYMPD together. I don't use Webui, only the mpd client.Music Player Daemon 0.22.4
Cantata is so easy to use that it can be used as a fully featured music server for Archlinux.
control by cantata and install radio by comand line sound is very much good archilinux sound
This operating system works by editing mpd from the SKY MPC and ssh command line. In other words, the detailed settings are configured using ssh. You can check the operation with runeaudio's WEBUI, but
I think cantata is the easiest to use. This is the fastest way to use RuneAudio. The sound is Achilinux sound. I use Moodeaudio as my NAS.
The Moodeaudio has a 2 tera hard drive, which I mount with CIF. If the connection is stable, this will allow me to transfer music from other servers to this one.
You can listen to music from other servers through this Archlinux music server.
# mount.cifs //192.168.1.2/a4C0-f0f0 /mnt/MPD/Music -o vers=1.0 iocharset=utf8
You can now load the music files from the NAS. For the internal share holder, type # chmod 777 /mnt/MPD/Music or similar from the command line to grant permissions.
so this version has HDMI can use monitor show Album picture. The sound of rAudio is very similar to the sound of Dietpi's compiled version of mpd 0.22.3. rAudio is Archlinux, but Dietpi sounds very similar to the sound of mpd compiled from source.
I think the previous version of rAudio sounds better, but it has the same tendency as Dietpi.
I've installed a new version of rAudio, and the low frequency sounds are much better.
The sound is exactly the same as the compiled version of Dietpi.
I'm not sure if this is a good thing or a bad thing.
You will need to build it with ssh. For internet broadcasting, create a Webradio directory under /mnt/MPD/, download Radio.tar.gz from outside and add it with Addon.
At first, I couldn't log in with ssh, but then I found a description in Github that said #root passwd is ros. This will allow you to edit via ssh.
New rAudio from github,

I've been using the FN1242A for a long time.
I've been using the FN1242A for a long time and it's a very easy to use voltage output DAC.
I think it's very easy to use.
I've been using the FN1242A for a long time.
The disadvantage of this Runeaudio (rAudio) is that it can't select music or stations, you can use SKYMPC to select music, Cantata is also fine.
if you have some problem mpd can not start .you can see error massage on WEBUI of RuneAudio.so use ssh can edit mpd.conf file.
The sound of this mpd and the mpd compiled version of Dietpi are very similar. It's hard to tell which is which in a blind test.
mpd should be compiled with the latest version of the sources.
I think that mpd has everything you need.The presentation of RuneAudio (rAudio) is very good.
a small shock can cause it to stop working.
RuneAudio has a disadvantage in that it is not stable enough to run in a distribution that stops working at all. In addition,
the use of new files for everything makes the library incompatible and unreliable.
This is one of the reasons why the development of RuneAudio has been halted. You need to be off the net to use it properly, and Samba is not perfect.
Since these applications have been removed, the RuneAudio music server cannot be used as a music server, and even if it could be used, it would not last long.
The sound is better and more stable with the Dietpi mpd version compilation. The unstable RuneAudio,rAudio. This has always been the case.
RuneAudio is not a regular version, but it can be updated with Pi Zero and a few. Pi4 is not possible. This is because it is not synchronized with Archilinux.
Zero, A, B, 2 and 3 can be updated.
When I actually update it, mpd is the latest 0.22.6. In Dietpi, it will be 0.22.6 depending on the compilation. I think you should also install emacs.
RuneAudio Linux is Archlinux so standalone music server.does not mount any NAS.
Update by SSH h3>
RuneAudio and any Archlinux family does not have smbd so can not use as Music Server is bad point
Raspberry pi B play by mpd 0.22.6 update pi4 can not Update h3>
In the end, SAMBA cannot be done. It's a stand-alone music server. If you use Cantata etc.,
the music of the work station will be read. You can also use Cifs-utils to read the hard disks of other music servers.
So, load the hard disk currently mounted on MoodeOS. As an example, access with ssh.
RuneAudio: ~ # mount.cifs //192.168.1.3/A4C0-F0F0 /mnt/MPD/NAS -o vers = 2.0 iocharset = utf8
This will load the Moode Audio hard disk. The control uses SKYMPC. Cantata is fine. Let me introduce two images.
Load with Cantata. Basically, the settings are made using the terminal.
Since the WEB UI is heavy, display it + set it slightly.
The sound is the sound of 022.6 mpd. This is a unique sound of Runeaudio.
Introduce Raspberrypi pico
raspberrypi pico as micro controller・C/C++、MicroPython only can not use Linux
assignment of pico raspberrypi
If I left runeaudio alone, I think I'm updating it without permission, and I'm also changing the WEB UI without permission. Something is easy to use. However,
Samba doesn't work, so I use CIF to link with other servers. For Webradio, create /mnt/MPD/Webradio as explained before and unzip Webradio here.
You can build an internet radio by configuring with Addon. Webradio can be wgetted from my site or brought from other external sites.
please use slimjet browz for control .slim jet get from
Slimi Jet browzer see good
Volumio3 is not buster In other words, mpd remained as it was. Why doesn't Volumio use Buster? does not have "no development ability??"
It remains mpd 0.20.18. Better yet, I think it's better to use mpd 0.20.9. If this is the case, the DSF will not skip.
Create m3u Create playlist
$ ls *.mp3 | sort> playlist.m3u
That's it. If you open the terminal and enter the above in the holder, m3u will be created automatically. Because I have Linux
This is easy to make. playlist name make proper name of file
The internal file is m4a, but please change only the extension
The cover can be displayed because there is a play list
Playlists are automatically generated by various methods such as Moodeaudio and Runeaudio, and each link etc. pulls in the carver image.
Generally, if you save it in a folder with a cover called folder.jpg
The image comes out, but I think that there is a hidden code in MP3 and WAV and it pulls in the carver.
I think it's also good to register on last.fm. However, these dangers extend to the hard disk
Because it searches, the cover may be displayed through Google from the label or Amazon, and if you are playing the music you are listening to in the room,
that is, the music on the hard disk, the same song will be displayed from the Internet radio.
What you hear is a very strange phenomenon.
Be sure to change the password as some people access it from the outside even if it is not connected to Wifi. OS is both Mood and Volumio2 Rune. The music server doesn't stop suddenly, so if someone accesses it or tries to fix it
It will stop in case of so it is recommended to change the password. Defaults are high risk and the contents of your hard disk can be stolen or deleted. be careful.

MKV youtube file sound conversion
MPD 0.22.6 can basically play anything. MKV used on youtube can be played in the same way as mp4. No format conversion required, although early MPDs couldn't play in any format
You can play the default mpd of Ubuntu Buter that is currently used in any format. Now MKV is easy to convert to MP4. If it can be converted to WAV, it can also be converted to DSF based on it.
The easiest way to use MKV is with VLC. The sound is very good even with MP4, and when played with Mood Audio, it is displayed as Mpeg.
VLC sound convert from MKV to wav
youtube MKV saved file play by MoodAudio 7.1
I think that people who have a site are in trouble due to the abolition of flash player.
I think the person who owns his site was very confused by the abolition of Adobe Flash Player at the end of 2020 last year. This was a fairly complicated script, but I played it using an embedding called fladance.
It was said that it can be played in HTML5. That said, you need to study HTML5 and you also need an application.
There has always been an easy way. So let's introduce it here. Youtube has a copyright relationship, so permission is not given and I upload it to Youtube by trial and error.
It usually doesn't go smoothly. h4>

This video needs to be edited with Avideomux because the same MP4 could not be played on the smartphone MP4. I got an error in the mp4 before edit.
For that purpose, edit the video to fit the website.
I'm using Avideomux of Fedora core Linux very much usefull application for edit video
If you do not edit the video taken with your smartphone to introduce the video, you will not be able to introduce it on this site and an error will occur. I edited this operation in detail more than 5 years ago.
Recently, thanks to youtube, I didn't edit these and just uploaded the video to Youtube. Since the flash player has been abolished, it is necessary to edit the video again.
In my case, I use Avideomux. I use it to edit AVI and MP4.
