I had one of these trivial problems. Yesterday I wanted to create a new stroboscope disc for my Metzner rebuild (now with 50HZ 🙂 … After fiddling around with some graphic tools I decided to build a small Web-App (quick and dirty) to support me on this task. It might be of interest? You can use it offline or via the web site…

Main Features:

– Supports 33⅓, 45, 78 RPM + custom speeds
– 50Hz, 60Hz, 300Hz lamp frequencies + custom frequency
– Adjustable disk size, bar length, smoothing
– Custom colors and logo upload
– Drag/rotate/resize logo interactively
– Export: SVG (print), STL/3MF (3D print), FreeCAD macro
– Light/dark theme, EN/DE bilingual
– Offline-capable (standalone download)
