Bypaulonair755 April 19, 2023February 28, 2025

I have a new lamp and wanted to connect it. Since the apartment only has old wiring, I connected it the same way the previous lamp was wired. However, the new one doesn't light up, except when I touch one of the wires with a multimeter or a voltmeter. Why is this happening, and how…

What is better with such information? 100 ppm 50 ppm 30 ppm 10 ppm I have always assumed that the smaller the number, the more accurately the frequency is maintained….

ByAISynex November 11, 2023February 27, 2025

I recently ordered an ESP-8266 12F ( https://www.amazon.de/gp/product/B0754N794H ) because I would like to do a WLED project with it using a WS2812B.

Heavy current – Why does the RCD always trip?

ByPeremy August 29, 2024February 26, 2025

Hello everyone, first of all I'm not an electrician, all the assumptions I'm making here are things I've googled. I'm renting a section of an old barn with a few friends as a workshop. We have our own (fairly new) fuse box with a residual current device (RCD) and domestic power, as well as 16A…

R = Makeln (= build up second conversation and then switch back and forth between the two conversations)
K = Short dial (in accordance with paragraph 0-9 or * or #)
M = Save (you can add a number during the conversation and then choose it later)
W = election repetition

Wow! Thank you. It’s really great. I had a phone standing at home when I was a youth book. But there was no guidance. I knew K. How to apply K? I have my button for pressing or switching, there’s only one diaphragm inside.

Here is the guide:

This is, however, for the variant with key switches, and one actually needs to store the shortcodes.

I don’t know how to do this without the key switch.

At M, the memory deceived me. When pressing during the conversation M, the last selected number is stored – and can then be selected again later by pressing the M (indirectly after lifting).

And what R does depends on the agency. Because R only generates a certain signal on the line. At the OES (so the Austrian Post called its system of digitized electoral offices) it was possible, as I described, to switch back and forth between two conversations.
