        Hi all,

        When experimenting with the NTC circuits, I noticed that there’s a difference between the Legacy and modern NTC version.

        Although the module looks the same, the actual NTC component differs in value.

        The legacy NTC looks like a carbon resistor and has a value of 15k Ω at 25°C or 77°F.

        The modern NTC has a value of 6,8k Ω at 25°C or 77°F.

        Since this is quite a big difference, care must be taken when designing circuits.

        For further experiments, I will add the NTC value on the diagrams to avoid errors.

        If you look at the post “The Impossible circuit”, I redesigned experiment 46 of the school (Ubung) system manual with different versions. Have a look and try these circuits out !

        Many greetings

          Thank you Frank for the latest challenges!
