      Andreis, I wanted to thank you for all your videos and the work and thought that goes into them. You are an incredible non biased person that helps this community immensely. I am a private pilot who has built my own plane in Western Canada and flown a similar plane in Austria and Denmark. Please let me know the best way of supporting your activities financially as this is a welcome and much appreciated resource for my hobbies and activities. B.T.W. I love the Swiss accent!

        Unfortunately, I cannot help here because I get a lot of such questions and have no time. YouTube is only my hobby.

    Hi Andreas, thanks for all the time you put in these web projects you do. It is really appreciated. I’m always looking for a new video and I’m a fan. Your channel and Dave’s are on the top of my list. I was wondering how you can manage all the time invested in producing your videos and still have some left for the rest of our hectic lives. Did you find a time machine or what?
    What can I say, keep it up, we love it. I’d like to visit you sometime and see how you do it. I live in Quebec so it’s a long swim for me.

    Gruetzi Andreas,

    And greetings from Lausanne…

    I saw your youtube vidéo https://www.youtube.com/watch?v=ZpKoLvqOWyc about the cheap VNA.
    I have difficulties in getting it from AliExpress. Can you share with me the exact Verkäufer you’ve used to get one?

    Thanks and great video you’re doing. If you happen to go through Welschland in the coming time just come by for a coffee. Have a look at what we’re doing on http://www.agorabee.com

      Hi Jari,
      Interesting stuff you do in the IoT field. It is probably a competitive area…
      Concerning the VNA: It should be easy to get a N1201SA ( http://s.click.aliexpress.com/e/5mmSQBs8
      ) My supplier unfortunately does not sell it anymore.

    Hi Andreas
    I have watched several of your videos and they are excellent. Keep up the great work. After watching one Docker and nodered Thought I would have a go myself. I have a little project using a Pi node red and docker to monitor my shed. The issue I am having is how to get access to bluetooth via docker and node red. Was wondering if you could offer any advice or maybe investigate in a future video.

    and keep going

    Dear Andreas,

    I want to get started with ESP8266 but I want to do using microPython. I just HATE C++ (aka Modula-2 for C) so Python, which I just dislike) is far more acceptable.
    Did you publish anything about Python on Arduino or Wemos D1? How do I load it? I guess the standard firmware of Wemos and Arduino will be the sketches thingy.

      I do not suggest using the ESP8266 for Python. It does not have enough memory. The ESP32 with PSRAM seems to be a much better solution

    Dear Mr. Spiess

    Im a founder of an IoT group of regulars of 4 engineers in Austria. We meet us normally in real but now over web and we talk about IoT like arduino, Esp32, different protokolls, nodered, docker, proxmox, 3DPrinting,… or we also try things every 1st Tuesday at 18:00 p.m. If you are interested to discuss with us, please let me know and I’ll send you a link or address

    Greetings from Austria

    Many of your projects has been concerning antennas. I am always looking at the VNA and impedance analyzers but a bit pricey for my hobby work. I can across this article and thought it might make a good video. Thanks for all your great work.

    Hello. I have a technical question about the Geiger counter (video #162). I have the sketch running on both an ESP8266 and ESP-32C3, but unfortunately I cannot get the input to trigger. The Geiger counter is clicking as expected, but no signal is detected on the “VIN” pin relative to GND. I also connected jumper P100 and was able to hear clicks on a headset, so I conclude that the Geiger counter is functioning properly. Still, the MCU is not getting triggered. I have run out of ideas. Thanks
