USB-C power connection for new swim nuts

If you want to use a USB-C mains connection – could this be different again? With USB Power Delivery (USB-PD) you can still use other devices with a DECT telephone, kitchen radio or guitar effect.

When the main function is switched on, you have a USB-C mains connection on the “Einstellung” button for the output voltage. The trade with the jewels was completed long ago. Welche Spannung und Leistung Sie a USB-C-Netzteil-tatsächlich entnehmen können, depends on more factors from.

Adapter with USB-PD chips, which enable the desired spannung, find a man at Amazon with such devices with “USB-C Trigger” or “PD spoofing”. Billing small plates with a USB-PD chip, when the man chooses the desired span for a large bridge and uses an automatic cable.

Teurere adapters are supplied in the form of a cable with the correct plug and a fixed voltage or with the sheathing. Vorsicht: The fresh display at a high voltage can be damaging to the affected person!

The alternate versions of the USB-PD specification are now available at voltages of 5, 9, 12, 15 and 20 volts for. But not your netzteil controls everything; There are many devices with a power of 60 Watts, a display at 20 V. The power of 65 Watts for notebooks depends on the 12-Volt profile.

The USB-C network is worth more than 3 amps of current, it is not true that most devices can mark an electronic USB-C cable (e-cable) with a rate of 5 A. Now there are some USB-C mains adapters with 5 A for low voltages such as 5 V or 9 V, depending on 12 V. This is not standard, so the specification is 5 A first based on 20 V.

When connecting USB-PD networks with USB-C purchases or the best cable and function programmable power supply (PPS), large voltages of 3.3 and 20 volts are set. Dafür braucht man aber compliziertere and teurere Adapter. Hackaday.io describes the “PPSTrigger” with an adjustment potentiometer as a basic project, under the configuration “Type ([email protected])

Fritzbox über VLAN and Glasphaser modem

My Fritzbox and the periphery were in the Keller stehen, or there was no funk connection in the living room. If you are using a fiber optic transmission, then the new router went to a fiber optic modem in the Keller. Enable a network cable. Can I connect the Fritzbox to the glass phaser modem in parallel via LAN?

Yes, that’s true: you can use two VLAN-capable switches. If the provider uses the Deutsche Telekom, the PPPoE glass phase is used and with the VLAN-Tag (DT: ID 7) version, the more you can reserve this VLAN in your network.

The ports, fiber optic modem and WAN connection to routers come, configure as Trunkports, the new package is added and expanded, VID 7 is shown here. Network zones use VLANs with VID 7 transport.

If your provider has a different VLAN ID for “Internet”, you can set it. It is not the case that labeling power, setting both ports is such that they now no longer add frames and plug into a VLAN. Dessen ID takes longer than free walking.

Creating a separate WAN cable is one way – in most cases this is unauthorized – One problem: the Internet traffic can be directed in a non-interconnected direction by the cable nut, if the internal host in the Keller stand is used at switches for Gigabit Ethernet with the maximum full capacity Duplex Bandwidth up to 1 Gbit/s halbiert.

During the time when the DT rates are high at a speed of 1 Gbit/s and at a speed of 0.5 Gbit/s, no hits can occur. If you find yourself in this situation, you can configure the switches for 2.5 Gbit/s Ethernet. The 1GE variants are still not available. ([email protected])

YouTube-Einladungen kommen nicht an

There are a number of YouTube channels available who are available as the channel’s administrator. Since my Google contacts address has changed and Google has sent an email message, this can be done. I think it’s a small matter. Was kann ich tun?

The problem may arise if there is a problem. The targeted emails are not clear. If you want to send the email, you can send an email: You can consult the address myaccount.google.com/brandaccounts and the “Ausstehende einladungen”. ([email protected])

Web app not started with Chromium application

I installed Linux Chromium with Flathub and pointed the browser at a website like Progressive Web App (PWA). Bisher is this page with an app in the list of meinerwending. I have now installed Chromium newly, no longer systemically, with flatpak --user install org.chromium.Chromium in my Home-Verzeichnis. Jetzt no longer finds Gnome the web app, but Chromium does. Was läuft falsch?

In Chromium, if you use a PWA, the browser becomes a .desktop data in the version ~/.local/share/applications/ an. In this einfach you can define the text date and the name, the icon and the start parameter. After the uninstallation of Chromium, the installation of PWA’s firmware is not possible, but the Gnome is already available. When you view the .desktop data, the org.chromium and the Default.desktop end with a text editor. Suchen Sie dort nach der Zeile

TryExec=/var/lib/flatpak/exports/bin/org.chromium.Chromium

There you can see the path hinter „TryExec=“ durch

TryExec=/home/USER/.local/share/flatpak/exports/bin/org.chromium.Chromium

You are here “USER” during your use of your own money. Lead functional references to ~ or $HOME in the .desktop data. Speichern Sie die Datei en nach einen Sekunden sollte der Eintrag wieder auftauchen. ([email protected])

Mail folder in Thunderbird can be edited offline

If you can receive an email with some data on my SSD, you can do some charging offline. Is it a simple way that you want to set up your own synchronization menu with your sets?

Yes, it’s a tattoo. Right-clicking on the sent email message and setting the context menus. You can check this box first under “Synchronization and Speicherplatz” on the next page, all order of the offline contact operations on your machine. The option says “Nachrichten für all Ordner dieses Kontos auf diesem Computer readyhalten”; About this special piece of paper “Erweitert” can be a single folder that you can create.

But Obacht: Gerade with langjährig and many genutzten E-Mail-Konten kan een umfangreicher Downloaden, it is not worth while to use the Mobilfunk-SIM and for the pleasure Platz on the Systemdatenträger bereitthehen muss. So the Thunderbird organization of the cars can be done in a normal way by the folder compression of 15 GByte on the mogul. ([email protected])
