The Learning Circuit - Make a Resistor Substitution Box!

Solder along with Karen as she shows you how to review resistor codes using a substitution box. The kit is useful for prototyping resistors. Once assembled, it can be used on an array of resistors, ranging from 10ohms to 1 mega ohm. The kit includes the knobs to switch from ohm to kilo ohm, a PCB, a bag of resistors, and the parts for the enclosure. It also includes a manual that gives you the placement of the resistors on the PCB, its value, and its color code. Karen is going to show you how to figure these out manually.
