A 3D-Printed Parametric Variable Capacitor
Since I am planning to resume this blog, I thought I’d share a fairly recent project. For a magnetic loop antenna build, I needed a variable capacitor that can handle relatively high voltages. These can be somewhat hard to come across today, and you have to work with what you can find on eBay voltage and capacitance wise. That’s why I came up with a variable capacitor that can be mostly 3D-printed, with the addition of some hardware store parts….
