Mike is the founder of The Geek Pub. A jack of all trades who simply enjoys the challenge creating things, whether from wood, metal, or from lines of code in a computer. Mike has created all kinds of projects that you can follow and build yourself, from many different styles of retro arcade cabinets to Arduino and Raspberry Pi projects.
One of the things I get told a lot is that people want a retro arcade cabinet in their home but that they simply don’t have a lot of room for it. Even bartop arcades take up a significant amount of space in smaller homes and apartments. So in this video, we’re going to make […]
In this tutorial, it’s going to be all about rectifiers! We’re going to learn the basics of their operation, and then we’re going to build a bridge rectifier circuit out of four diodes that can be used in your projects to convert AC to DC. In a previous tutorial we talked about diodes and how […]
In this project we’re going to make a USB charger circuit from some simple parts we have lying around the house. A USB charger circuit ouputs a regulated 5V that can be used to power USB devices or even charge mobile phones and other devices. We will step through this build in 4 phases of […]
Oscilloscopes are super handy tools to have around the workshop. With an oscilloscope you can test electronics and devices to see if they are functioning correctly, and make repairs. In this article and video, we’re going to do a basics 101 oscilloscope tutorial and learn how they work! Watch The Oscilloscope Tutorial Video Let’s start […]
If you’re into retro-computing and have a Commodore 8-bit computer, such as the Commodore 64 or Commodore 128, you’re going to love this project! We’re going to do a Pi1541 build. The Commodore line of 8-bit computers used a disk drive called the Commodore 1541 (later the 1571 and 1581). This venerable drive is a […]
In this tutorial, we’re going to answer your burning question: “What is a capacitor?”! Capacitors are one of the most basic components used in electronics and most all of our projects incorporate a capacitor in some form or another. Understanding how they work and how to use them is a skill most beginners should learn. […]
In this tutorial we’re going to answer the fundamental question that you’ve all been asking recently, “What is a diode?” A diode is a fundamental component that is at the very basics of many electronics projects. Unlike some of the passive components we’ve talked about recently (like resistors), a diode is a semiconductor. And as […]
In this tutorial we learn how to do do an Arduino Celsius to Fahrenheit conversion (and Fahrenheit to Celsius too!). It’s a pretty simple operation and one that is asked quite often in the forums. Understanding the Difference Between Celsius and Fahrenheit So before we learn how to do an Arduino Celsius to Fahrenheit conversion, […]
