Welcome to RhPf Electronics Nerd Lab, a space dedicated to the inner details of pedal design, circuit experiments, and tone exploration. Whether you’re a pedal builder, a gear geek, or just someone who loves to understand what makes a stompbox tick, you’ll find tools, research, and insights here to feed your curiosity. From diode voltage curves to op-amp comparisons, from circuit simulations to real-world testing, this is where the pedal nerdery runs deep. Dig in, experiment, and let’s push the boundaries of tone together!
Diode Curve Plotter – A Visual Guide to Forward Voltage
Explore the voltage characteristics of over 200 diodes with the RhPf Nerd Lab Electronics Diode Curve Plotter. This interactive tool lets you compare forward voltage curves across different diode types—germanium, silicon, Schottky, and more—helping pedal builders and circuit designers make informed choices for clipping, rectification, and beyond. Dive in and tweak your tone at the component level!
