Cutting to the "shopping list" section:

We focused on using “off the shelf” components and open-source software to develop the wireless endoscope. This significantly lowered the cost with the goal to make the device accessible for resource-constrained environments. While the technology described is applicable to a variety of rigid lens applications, we attempted to replicate the 4 mm cystoscope lens and separately a clip-on universal endoscope camera.

2.1 Hardware systems

A miniature single-board computer (SBC) module the Raspberry Pi Zero W (Raspberry Pi Foundation, Caldecote, UK) was used because of its size, its low cost (US$10) and its ability to handle high-definition (720p) video.

A 3.7-mm tube camera (model: 1001LG, Shenzhen Eastern International Corporation Limited, Shenzhen, China) was used. It delivers 1280 × 720 high-definition video using a 1/7″ colour CMOS sensor. Lens construction allows a wide (115 degree) field of view and an extended depth of field allowing object in the range of 5 to 50 mm to be in focus. Connectivity is via a USB 2.0 interface with the SBC. The camera is certified IP67 waterproof and the manufacturer is ISO 13485:2016 certified for the design and manufacturer of medical endoscope cameras.

Illumination is via 6 high luminous 0603 white colour LEDs incorporated into the tube camera. The system was powered by a 1200mAh lithium polymer battery and incorporated into a fireproof acrylonitrile butadiene styrene enclosure.

For the clip-on wireless camera module, an 18–35 mm optical zoom coupler (Ouman Medical, Jiangsu Ouman Electronic Equipment Co., ltd, Jiangsu, China) and an 8-megapixel camera module (model: IMX219, Arducam) were used.

2.2 Software systems

Open-source Linux software was used on the SBC as follows:

1. The SBC runs on the Raspbian Pi operating system Lite, a minimal image of Debian Buster [9]. 2. The SBC Wi-Fi module is placed in monitor mode (“hotspot”) using RaspAP [10]. This makes wireless video transmission possible. 3. The video signal is streamed via the UV4L module of “Video 4 Linux 2” [11].

4. Lastly, the wireless video signal is viewed on a standard computer via any internet browser. Figure 2 illustrates the entire software setup.

Okay, so I had trouble with the procedure to SSH into Armbian and to install Open Media Vault 6 a few weeks ago and reflashed the SD card with standalone OMV4 from four years ago. But I can't install any plugins or updates because they moved hosts and the script to change the address of the repository only works for OMV 5 and up.

When I figured out what my problem with SSH had been (I actually think the firmware image was bad and the NAS machine wasn't actually booting), I already had the OMV4 install set up and integrated into my workflows (play flows?) so I was reluctant to overwrite it try flashing Armbian again.

It turns out that class 10 32GB micro SD cards are like five bucks, so I just bought another one to swap out on the assumption that I could switch boot media back quickly without messing up any settings if something went wrong.

More misadventures under the cut.

I put the Armbian card in the machine and booted it up, this time successfully signing in by SSH. Following a guide on a Reddit tab I've had open since before the blackout I downloaded and installed updates and then went to the third party software installer. And OMV wasn't on the list.

Turns out the latest version of Armbian, Jammy, doesn't have OMV support. This has something to do with being based on Ubuntu instead of directly on Debian. So I need to downgrade to Buster or Bullseye. That means pulling the card and flashing again. Glad I didn't overwrite the OMV4 image.

After a brief panic where the machine appeared to boot successfully but didn't appear on the network (I forgot to plug the network cable back in after unplugging it to get at the SD slot), everything was just where I left it. Unfortunately, Kodi on my primary Android TV refused to open and I had to clear its data and re-import the library anyway. Backed it up once I was done so I shouldn't have to do that again.

I did have a bit of trouble finding a legacy image of Armbian Bullseye to download but it's ready to go the next time I'm ready to tinker.

Record voice with recorder.js and upload it to python-flask server, but WAV file is broken

I would like to realize this.

A user speaks to a web browser.

A web browser (Google Chrome) record user's voice as WAV file(Recorder.js) and send it to a python-flask server.

I realized this with the help of addpipe's simple recorder.js sample.https://github.com/addpipe/simple-recorderjs-demo

This sample uses php server, so I changed the original app.js.

original app.js

xhr.open("POST","uplod.php",true);

my app.js

xhr.open("POST","/",true);

I checked my web app locally, then everything looked perfect. I use Windows 10, WSL, Debian 10/buster, python3.7.6, Google Chrome. Here is Terminal's record.

127.0.0.1 - - [03/Feb/2020 11:53:17] "GET / HTTP/1.1" 200 -./file.wav exists127.0.0.1 - - [03/Feb/2020 11:53:32] "POST / HTTP/1.1" 200 -

However, when I checked uploaded "file.wav" with ffprobe command, it was broken.

This is screenshot of my app. When I push "save to disk" button, I can download WAV file locally.If I check downloaded WAV file, it is not broken.

Das Ende von Android Apps auf Chromebooks?

Es könnte der Anfang vom Ende der Android Apps auf Chromebooks sein. Bereitet Google hier einen Strategiewechsel vor?

Die Anzeichen tauchen in den ChromeOS Flags auf. Dort wo Google den Nutzern von den Kanälen Beta und Dev bereits experimentelle Funktionen zur Verfügung steht. In der Regel müssen solche Funktionen aktiviert werden. Jetzt zeigt sich dort offensichtlich, dass PlayStore Apps ab- bzw. eingeschaltet werden können.

Kurz zur Historie und um was es da eigentlich geht. Chromebooks sind die Google Hardware Alternative zu den bekannten gängigen Computer Betriebssystemen, die mit chromeOS, dem von Google weiterentwickelten Betriebssystem auf Linux Basis angeboten werden. Das hat sich in den letzten rund zehn Jahren massiv weiterentwickelt, bietet heute die Möglichkeit neben den wenigen chromeOS eigenen Anwendungen eben auch Android Apps und sogar Linux Apps gleichzeitig zu nutzen.

Dadurch haben Chromebooks im Bereich der Auswahl im Zugriff auf viele Anwendungen massiv an Attraktivität gewonnen. Linux Apps müssen aber erst in einer Art Entwicklermodus aktiviert werden, um diese dann nutzen zu können. Das war zu Beginn der Einfürhung auch bei Android Apps der Fall. Da nicht alle Chromebooks damals in der Lage Waren mit Android Apps umzugehen musste die Funktion PlayStore Apps zu Beginn ebenfalls zunächst aktiviert werden.

Ein wichtiger Aspekt dabei ist das ein Chromebook gerade zu beginn über ein Touchdisplay verfügen musste, da viele Android Apps eben auf die Touchbedienung angewiesen sind. Das ist heute nicht mehr ganz so wichtig. Dennoch laufen auch Chromebooks eben nicht alle Androif Apps, welche im Google PlayStore zur Verfügung stehen und es hängt heute mehr denn je vom jeweiligen Typ eines Chromebooks ab. Etwas das die Entscheidung beim Kauf schwierig macht, weil man es zu diesem Zeitpunkt schlicht nicht wissen kann.

Seit einiger Zeit muss die Android App Funktion auf einem Chromebook nicht mehr explizit aktiviert werden, sondern wird quasi erzwungen. Viele Nutzer sehen daran eher einen Nachteil. Viele sind an die Nutzung gerade von Google Anwendungen im Browser oder als PWA App (Progressive Web Anwendung) gewohnt, die schlicht mehr Möglichkeiten bei besserer Übersichtlichkeit bieten. Wenn sich dann ständig die gleichen Anwendungen prinzipiell erzwungen in Android Apps automatisch öffnen ist dies ziemlich nervig und auch überflüssig.

Nun könnte sich abzeichnen, dass Google hier wieder zurück zu den Anfängen geht und Android Apps nicht automatisch aktivert und erzwungen werden. Zudem gibt es noch ein Problem. Um Android Apps nutzen zu können muss es ein Android PlayStore Konto mit einer hinterlegten Zahlungsmethode geben. Bei geschäftlicher Nutzung von Chromebooks ist das schlicht nicht erwünscht und so müssen Nutzer oft neben einem Workspace Konto noch zusätzlich ein herkömmliches Google Konto auf den Chromebook einrichten.

Erfahrungsgemäß sind viele Nutzer die im Laufe der Zeit gelernt haben sich besser mit ihrem Chromebook auszukennen auch nicht mehr an Android Apps so stark interessiert. Dennoch ist es wertvoll im Zweifelsfall diese Option zu haben. Ein weiterer Vorteil bei Android Apps ist, dass diese in der automatischen Sicherung berücksichtigt werden. Das ist bei Linux Anwendungen immer noch nicht der Fall. Hier müssen die Nutzer regelmäßig selbst Backups anschieben.

Und auch da gibt es ein paar Probleme, denn bei einem Update des Linux im Container können solche Backups ggf. nutzlos werden. Beim wechsel von Debian Buster auf die aktuelle Versione mit dem Codenamen Bullseye mussten die Nutzer eine schlimme Erfahrung machen, die sich hoffentlich so niewieder wiederholen wird. Gerade Entwicklern ist die Nutzung von Linux auf Chromebooks aber viel existentieller, als es Android ist.

Gewisse Android bausteine werden aber wohl auf Dauer enthalten bleiben, weil man bei Google viel unternommen hat Android Smartphones und Chromebooks zu verbinden. Beispielsweise um einfach Bilder zu verschieben oder gewisse Infos des Smartphones auf dem Chromebooks zur Verrfügung zu stellen. Das hat sich als extrem sinnvoll gezeigt und dürfte auch unter dem Aspekt das Anwendungserlebnis von chromeOS etwas Windows vergleichbarer zu machen, nicht mehr aufgegeben werden.

Allerdings ist es eben auch sehr enttäuschend, wenn Android Apps die man gerne nutzen möchte, dann sich auf dem Chromebook nicht installieren lassen, weil das Chromebook eine andere Android Version nutzt oder nicht den geeigneten Chip verbaut hat. Viele Websites bieten heute die Möglichkeit sich als PWA's ausführen zu lassen, was bei einem Chromebook die Ausführung in einem eigenen Fenster ermöglicht und vieles einfach macht. Das dürfte der bessere Weg sein. Android Apps bieten aber noch einen Vorteil. Sicherheit. Die Installation eben von Apps die von Google überprüft wurden und als sicher befunden wurden.

Ob es überhaupt nun zu einem Strategiewechsel und solchen Anpassungen kommen wird ist heute noch nicht klar. Google hat mit Chromebooks noch ein ganz anderes Problem. Diese benötigen immer ein Google Konto, sonst sind Chromebooks kaum nutzbar auch wenn es die Gast-Funktion gibt. Diese enge Bindung an Google könnte irgendwann ggf. von Wettberwerbshütern als problematsich erkannt werden. Dann müsste Google es ermöglich sich auch mit einem eMail Konto eines anderen Anbieters an einem Chromebook anmelden zu können. Das aber würde die grundsätzliche Architektur von chromeOS und dem automatsichen Hintergrund Backup im Google Drive konterkarieren und wäre das AUS für Chromebooks.

MongoDB clusters can be deployed in HA setup to guarantee availability of VPN system in your environment. Pritunl works on client-server architecture, where user profiles are downloaded on clients, while servers and users are configured on the VPN server. Pritunl is built on MongoDB – a highly scalable, and reliable NoSQL database solution. MongoDB has support for replication that can be done in minutes making a Pritunl cluster deployment fast and easy. Setup Pritunl VPN on Debian 11 / Debian 10 / Proxmox VE In this section we’ll discuss the installation and configurations of Pritunl VPN server on Debian 11 / Debian 10 / Proxmox VE. We recommend you perform this installation on a fresh installation of Debian Linux. Also ensure you access the server as user with sudo privs or as root user. Step 1: Update Debian system Login to your Debian machine and perform an update and optionally upgrade all packages on the system. sudo apt update && sudo apt -y full-upgrade After updates are committed, check if a reboot is required on the system. [ -f /var/run/reboot-required ] && sudo reboot -f Step 2: Add MongoDB and Pritunl repositories Install basic utility packages required for this operation: sudo apt update sudo apt install gpg curl gnupg2 software-properties-common apt-transport-https lsb-release ca-certificates Import MongoDB APT repository keys to your system. curl -fsSL https://www.mongodb.org/static/pgp/server-5.0.asc|sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/mongodb-5.gpg Import Pritunl VPN GPG keys: $ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv 7AE645C0CF8E292A Executing: /tmp/apt-key-gpghome.6ZjhVSgCdC/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com --recv 7AE645C0CF8E292A gpg: key 7AE645C0CF8E292A: public key "Pritunl " imported gpg: Total number processed: 1 gpg: imported: 1 Add Pritunl repository: echo "deb http://repo.pritunl.com/stable/apt $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/pritunl.list Add Mongodb repository by running the commands below: echo "deb http://repo.mongodb.org/apt/debian buster/mongodb-org/5.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-5.0.list Step 3: Install Pritunl and MongoDB With both repositories added and confirmed to be working let’s proceed to install pritunl and mongo-server packages. sudo apt update sudo apt install mongodb-org pritunl Now start and enable Pritunl and MongoDB as below: sudo systemctl start pritunl mongod sudo systemctl enable pritunl mongod Step 4: Configure Pritunl VPN Server Our Pritunl VPN server is now installed and running.

Next we access its web console on a web browser server’s IP to configure it. http://. You’ll need Setup Key to proceed. Run the command setup-key to generate it: $ sudo pritunl setup-key c76683c87efe4774887a9a223a2f1fd6 Once you enter the setup-key and mongodb url, it will prompt you for username and password. The default username and password are obtained with the below command: $ sudo pritunl default-password [undefined][2022-06-28 15:13:50,043][INFO] Getting default administrator password Administrator default password:  username: "pritunl"  password: "vzjTDicF92Ol" You’ll land on a page like below where you can change admin user and password, set domain and Let’s Encrypt SSL. Next configure organizations, users and servers. VPN users are added by clicking on ‘Users’. Users are mapped to server in an organization. To create a new organization click on ‘Add organization’ then specify a name and ‘Add’. Create a VPN server by clicking on ‘servers’ then ‘Add server’ Provide server information required then click ‘Add’. Finally attach the server to an organization by clicking on ‘Attach organization’ and choosing your organization. Adding users Click on ‘Add user’ to create a user profile on your VPN server. To add many users at once use the ‘Bulk Add user’ function on the web interface. Step 5: Configure Pritunl Clients Visit the Pritunl VPN clients page and choose one for your Workstation to download and install. Once VPN client has been installed, login to Pritunl VPN server to download user profile. Click on ‘Users’ select the particular user and click on the download icon to get the user profile.

Once you log in, you will be redirected to the Webmin dashboard, which provides basic information about your system. Login to the Webmin web interface using your root or sudo user credentials. By default, Webmin uses an untrusted self-signed SSL certificate. NOTE: To access Webmin Web Interface, open browser and type your server’s hostname name or public IP address followed by the Webmin port 10000: Note that you may see that the browser complains about the certificate being not valid. You can also run the command to make things easier:įirewall-cmd -zone=public -add-port=10000/tcp -permanent Step 4: Open Webmin Port on Ubuntu Firewall.

Ubuntu 20.04 install webmin install#

Step 1: Update the System and Install Requisites Packages. Example: If the Webmin server doesn’t respond, you might need to adjust firewall settings to allow port 10000. In this article, we take a look at how you can install Webmin on Ubuntu 20.04 and Ubuntu 18.04 so that you can seamlessly manage your system. You need to open the port in your firewall so that the Webmin interface is accessible from the Internet. NOTE: By default, Webmin listens for connections on port 10000 on all network interfaces. Once Webmin is installed and runing, you can access Webmin via the IP or web address you supplied or were given by the system. The Webmin service will start automatically. You can now login to as root with your root password, or as any user who can use sudo to run commands as root. Once all the dependencies are installed, the following output will be displayed: Sudo sh -c 'echo "deb sarge contrib" > /etc/apt//webmin.list' Just input or copy and paste the text below and hit Enter/Return: The commands below add the Webmin repository to your system and install the latest version of Webmin and all necessary packages. Sudo sh -c 'echo "deb buster main non-free" > /etc/apt//nonfree.list' On Debian, make sure that wget is available first: You can add the Webmin repository (webmin-repo) and use Jamie Cameron’s key to install and maintain the latest version of Webmin/Usermin.

Basic SPICE components: RCL, BJT, MOSFET, JFET, MESFET, switches.SPICE model could be added to schematic without any adaptation. Direct support of SPICE models from components datasheets.Backward compatible with Qucs by the component types and simulations.Hi-Fi bipolar transistor audio amplifier.SpiceOpus is developed by the Faculty of Electrical Engineering of the Ljubljana University.It supports basic SPICE simulation types and has an advanced RF simulation features such as Harmonic balance simulation.

#Qucs icon alpha layer simulator#

XYCE is a new SPICE-compatible circuit simulator written by Sandia from the scratch.

It has an excellent performance for time-domain simulation of switching circuits and powerful postprocessor. The most of industrial SPICE models are compatible with Ngspice. Ngspice is powerful mixed-level/mixed-signal circuit simulator. Qucs-S allows to use the following simulation kernels with it: The schematic document format of Qucs and Qucs-S are fully compatible. Qucs-S is not a simulator by itself, but it requires to use a simulation backendwith it. Qucs intentionally uses its own SPICE incompatible simulation kernel Qucsator.It has advanced RF and AC domain simulation features, but most of the existing industrial SPICE models are incompatible with it. It merges the power of SPICE and the simplicity of the Qucs GUI. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI. What is Qucs-S?Qucs-S is a spin-off of the Qucscross-platform circuit simulator. (More screenshots.) PublicationsQucs-S is also a research software. Simulation example with Qucs-S and Ngspice
