Is there a museum in Germany where the emphasis is on engineering?

There's one science museum called Deutsche museum in Munich.

Deutsches Museum in Munich is the biggest one (and most interesting I think) but there are many others, such as the the Autostadt in Wolfsburg, several car-oriented engineering museums (Daimler-Benz and Porsche in Stuttgart, BMW in Munich), a big and very interesting railway history museum in Nuremberg... what are you actually interested in?

... the Thechnikmuseums in Speyer and Sinsheim, the museum of mining in Bochum, Völklinger Hütte near Saarbrücken (old steel factory), museum of communication in Frankfurt...

There is a zepplin museum on Constance as an engineer I found it great
