Can you believe it! We are on our second to last lesson in our PyroEDU Analog Electronics course…only 1 left after this! In this Lesson, we will expand on the Intro To OpAmps from the basics course and actually build an OpAmp Amplifier. Here’s a quick intro of what this PyroEDU lesson is all about:

A different type of standard amplifier uses what is called an op-amp. This type of amplifier is very easy to setup and design with widely available formulas for how they work. In this lesson we will put these equations to work and build a basic 741 opamp amplifier, testing it out with an audio input signal.

This week in our PyroEDU Analog Electronics course, we dive into transistor amplifiers. Here’s a quick intro of what this PyroEDU lesson is all about:

When it comes to analog electronics, amplifiers are just as important as filters since they serve the purpose of amplifying filtered signals. In this lesson we will build a simple single transistor amplifier and see its effect on an AC sine wave input.

Now for a really fun lesson in our PyroEDU’s Analog Electronics course! This week we dive into Active filter circuits. Here’s a quick intro of what this PyroEDU lesson is all about:

This type of analog filter is one that utilizes op-amps which can make sure the input signal is the same strength as the output signal. In this lesson we will build an active band-pass filter and see the effect it has on an audio signal when we vary its parameters.

This week, PyroEDU’s Analog Electronics course is featuring a lesson on RLC filter design. Here’s a quick intro of what this PyroEDU lesson is all about:

When we combine together a low pass RL and a high pass RC filter, the result is an RLC filter which filters both low and high frequencies out of a signal. In this lesson, we will learn how to build an RLC filter, see what formulas are necessary for designing an RLC filter and experiment with understanding the effect an RLC filter has on an audio signal.

It’s that time again! We’re releasing another lesson on PyroEDU for our Analog Electronics course. This week the lesson is about Passive Analog Filters. Here’s a quick intro of what this PyroEDU lesson is all about:

The most basic passive analog filter comes by combining together a resistor and a capacitor or a resistor and an inductor. In this lesson we are going to learn how to build and design some basic RC and RL filters and see the effect of these filters on a simple audio signal.

This week at PyroEDU we’re going to be adding another lesson to the Analog Electronics course, called Zener Diodes. Here’s a quick intro of what this PyroEDU lesson is all about:

The zener diode is a special type of diode that allows current to flow through it in either direction, however only at certain voltages. In this lesson we will learn how zener diodes affect AC and DC signals and perform some experiments to see those effects.

Now it’s time for this week’s Analog Electronics lesson! This time we will explore more about Rectifier diodes. Here’s a quick intro of what this PyroEDU lesson is all about:

In electronics, diodes serve a unique purpose in that they only allow current to flow through them in one direction, which makes them useful for blocking unwanted voltages and guiding current flow. In this lesson, we are going to use that unique property of diodes to rectify a simple AC signal into a flat DC signal.

Are you ready for another Analog Electronics lesson? We are! This week we will explore more about AC vs DC Electricity. Here’s a quick intro of what this PyroEDU lesson is all about:

Understanding the difference between DC and AC electricity is the first step towards understanding analog electronics. In this less we will go over some theory about what AC electricity is, what it looks like and how it is different from DC electricity. Additionally, we will build an example AC circuit that generates a tone.

This week we’re launching our brand new course: An Introduction To Analog Electronics. We’ll start by looking at The Intro. Here’s a quick intro of what this PyroEDU lesson is all about:

If you have never studied analog electronics before and want to get started learning about AC, DC, filters and amplifiers this is where you should start. This first lesson explains what this course is about, what tools you’ll need to follow along with the course and what expectations you should have from taking this course.

In 2 days, PyroEDU will be introducing a new course: An Introduction To Analog Electronics. Here’s a quick summary of the course and some links with more details.

This course is meant to create a pathway into learning about analog electronics, for people who are scared of the math and general trickery that usually comes with it. A hands-on approach is taken in this course through a combination of lecture and experimentation to teach you about the different basic ideas (AC vs. DC, filters and amplifiers) used in analog electronics.
