Dear all,  the Software gets some fundamental rework as we are working on a updated harware revision. The work done for the last version 1.5 will be included int the software as well so some other nice goddies like sd-card support. We try to get also some new protorcols supported and try to fix some parts that looked not that nice. Further progess will be found here: https://www.elektormagazine.com/labs/remake-elektor-weather-station

Hi, Great box, it looks nice. I looked at your schematics, maybe you could try to study it's loop gain stability and improve it with simulation. https://www.youtube.com/watch?v=fODXWfY1oHE it's a very interesting subject. Best regards

Now I have purchased a 150 W solder tip and a switched power supply that provides 12 V and just over 12 A. I saw the software change you made - excellent! The question I ask is now if I move (desolder) the FET IRF 9540 that sits there on the circuit board to a heat sink so that any power dissipation that may occur is taken care of - can there be anything else that I forgot to think about? And I am aware of the fact that :  It is stated that alterations in hard- and software are NOT supported by Elektor. Grateful for answers !
