## How to Set up an Extech Power Supply

This video describes how to set the current limit and use an Extech power supply.

## How to Set up and Use a BK Precision Power Supply

This video describes how to set the current limit and use an BK-Precision power supply. Constant current and constant voltage are discussed. Note: Use power supplies in dry areas away from flammable objects.

## How to Measure Capacitance and Resistance Using a Multimeter

In the video I demonstrate how to use a multimeter to find the resistance of a resistor and the capacitance of a capacitor using a multimeter. In the video, test two different types of capacitors and two resistors resistors.

## How to Measure DC and AC Current Using a Multimeter

In the video I demonstrate how to use a multimeter to measure DC and AC voltage. I show how to measure current in a series circuit.

## A Journey into Music and Sound Part II: Matlab IDE and wavread

This video is part two of a series that looks at music and sound from a mathematical, science, and engineering point of view using Matlab.In this specific edition I discuss the Matlab development environment and using Matlab to extract data from a .wav file.
