| Our old friend Norbert “HomoFaciens” Heinz has been at it again. Norbert’s builds are consistently some of the most thorough and interesting we get to see. (They’re also fantastically narrated, and produced in both German and in English.) Norbert’s latest is a crystal-clear explanation of how hanging plotters work; you’ll learn about the electronics involved in building one – you’ll be winding the cord that suspends the pen around the shafts of stepper motors; as well as about the maths the software uses to calculate how to use the pen (this is a great lesson on applying all that stuff you learned about Pythagoras in school). You can read a full write-up of the project in English at HomoFaciens.de – there’s also a German version available. Thanks Norbert!
