A RECENT VIDEO

This video examines the operation of the Adjustable Sawtooth Generator you often see in my videos.

The video features a breakdown each sub circuit using both a circuit simulator software and components on a breadboard in the lab.

In approaching it this way we are introduced to several circuit building blocks, content current sources, capacitor charging, a diode switch, and a comparator with hysteresis.

Clean Boost Circuit Improvements

In this article, we examine improvements we can make to a simple Op Amp Clean Boost circuit to make it more suitable for commercial production.

Adjustable Sawtooth Generator

Here we explore the operation of the Adjustable Sawtooth Generator you often see in my videos.
We learn about constant current sources, capacitor charging, diode switches, comparator circuits and hysteresis.

Oscilloscope Music

Recently, the Telequipment D66a vintage analogue Cathode Ray Tube (CRT) Oscilloscope has been pressed into service using X-Y mode to curve trace transistors, diodes, capacitors, etc. The patterns this creates on the screen are named Lissajous or Bowditch curves, named...

Guitar Pedal Switching – Part 1

This is the first in a series of videos where we look at the processes involved in making a Guitar FX Pedals. Here we explore some of the more common types of bypass switching found in Guitar FX pedals. Starting with a look at basic switches, switching circuits and...

Clean Boost Guitar Pedal Series

In this series we start by building a build a Clean Boost circuit for Electric Guitar, we troubleshoot any issues before moving on to modifying the circuit by adding soft and hard clipping diodes before looking as the area of the circuit that we can improve using a better power section and by employing filters to address noise and frequency response. This series will continue duirng 2023 with several more parts including implementing a tone circuit, adding gain & volume controls, and finally designing a PCB.
