Getting started with the Altera DE1 FPGA board: Create and download a simple counter

This is my first experience with FPGA programming, and so I made this video to show how easy it is to get started. Many of the tutorials on the web and the DE1 manual make the process seem more difficult than it actually is (as usual).

Tutorial: Electrical impedance made easy - Part 1

This is the first video of a short series in which I discuss the basics of electrical impedance from a practical standpoint.

In this video, I show how a simple LED power supply circuit can be made more efficient by replacing a resistor with a capacitor. I describe the difference between resistance, reactance, and impedance.

How to design a transistor circuit that controls low-power devices (tutorial)

I describe how to design a simple transistor circuit that will allow microcontrollers or other small signal sources to control low-power actuators such as solenoid valves, motors, etc.
