LiminousFluxPlanner is a handy toolkit for people who build lights and electronics. It helps you plan LED dimming and total light output in a clear, simple way. You also get quick tools for capacitor shapes, stitch vias, and clean return paths. Our camera exposure helper makes it easy to set lux-seconds for good images. We include fast checks for edge fringing capacitance and coplanar waveguide gaps. Tune differential micro strip pairs to the right impedance with just a few inputs. Check via current sharing and heat rise so your boards stay safe and reliable. Convert between watts and lumens, and scan ground fills for resonance risks—everything in one place.
