 There are other, more detailed analyses, looking behind the curtains of ChatGPT, this is just a short summary of my own experiences. For more details, look e.g. here: ChatGPT: Interacting via a conversational way! ChatGPT is this (in)famous artificial intelligence which has been all over the media lately. It describes itself as a language […] Continue reading We need to talk about ChatGPT  sagecell.makeSagecell({“inputLocation”: “.sage”}); Following a discussion on Facebook I put here an online tool to calculate the output of a voltage divider consisting of a fixed resistor and an NTC thermistor following a first order Steinhart–Hart equation. The calculations are based on a voltage divider where either the voltage over the NTC or over […] Continue reading Temperature measurements with an NTC thermistor  Today I received a newsletter from the publisher Elektor. I am offered a special deal on a Peltier power generator which can power an LED light from a small candle. And this for an astonishing price of €99.95 instead of the normal price of €119.95.

A short while later also the male arrives with a beak […] Continue reading BirdCam – feeding in slow-motion  “I’m hungry!” Ten days Mrs Fieldfare has been sitting in her nest – today was the big day: until late afternoon three eggs had hatched. Now also Mr Fieldfare has to show some effort who has not been much around the nest lately. Mr and Mrs Fieldfare at the nest. […] Continue reading Hatching time  It took four attempts to finally get a suitable webcam to observe the bird’s nest outside my office window. Most cheap webcams, even those which show off with true 720p HD resolution simply cannot cope with the different outdoor lighting conditions over a full day. After a lot of testing and research on the […] Continue reading BirdCam v4 I had some problems with fswebcam to set the automatic exposure. The exact way how to enter certain parameters is not clear from the lacking documentation, but it works fine if you set parameters through another command line tool.
