The RC Box by Parasit Studio is a utility box designed for circuit development and breadboarding. It is a passive resistor/capacitor utility box that can be used for circuit development, breadboarding, or modification work. The RC Box allows you to quickly toggle between different values of capacitors or resistors by hooking it up to your circuit with alligator clips.

Unlike traditional RC boxes that are point-to-point wired and use expensive rotary switches, the RC Box is designed to be easier and less time-consuming to build. It features three rotary switches for selecting from 36 different value resistors and 36 different value capacitors. Two toggle switches are also included to select which rotary switch is in use.

The RC Box can be easily configured as an RC lowpass or highpass filter, making it a versatile tool for various circuit applications. It started as a personal build but has gained popularity, leading to the production of PCBs for wider availability.
