A voltage regulator is a super handy electronic component to have in your arsenal. A voltage regulator converts unregulated voltage that could be fluctuating (or is a higher voltage than the device your device needs to operate) and converts it to a perfectly stable voltage that won’t change even if the input changes. In this […]
Many of you may not be familiar with just how handy a multimeter can be! A multimeter is a handy electronics meter that test voltage, resistance, and continuity in its most basic form. More advanced multimeters can even measure capacitance and temperature. In this tutorial, we’re going learn the basics of how to use a […]
In our first tutorial about basic electricity, you learned that current is just the flow of electrons in a wire. You learned about current and that its unit of measurement Amps refers to how many electrons are flowing past a certain point per second. In this tutorial we’re going to answer the questions you’ve all […]
This is new set of tutorials on the basics of electricity. I am often asked some of these questions, and I thought it would a great idea to have a place to share and send people to for the answers. Today we’re going to answer the question “What is current?” It’s a confusing topic and […]
I talk to people every day about computers and electronics. From friends and family, to business colleagues, to vendors selling equipment. There is one statement I hear constantly and it drives me crazy. “The Wi-Fi [here/there/at home/at work] sucks!” This is so frustrating because in this day and age (it is now 2021 after all) […]
The world is changing. Technology is invading the home like never before. Builders are even including structured network panels in smaller homes, and dedicated network closets in larger homes. These dedicated spaces often include a shared space for audio/video gear for things such as whole home music systems and theater rooms. It’s not uncommon for […]

In this tutorial, its all about Teensy vs. Arduino! What’s the difference? Why use a Teensy over an Arduino or vice-versa? We will touch on the basics and then dive into a few key areas to help you understand when you should use one over the other. Both are fantastic platforms with lots applications and […]
So I found a fantastic Commodore VIC-20 at a yard sale and it is absolutely gorgeous! It has Just a slight bit of yellowing that you can barely see and a few tiny scratches here and there… but other than that it is in tip top shape. Except for one thing. The clips on the […]
In this tutorial, we’re going to cover using the the DHT11 (or DHT22) temperature and humidity sensor with the Raspberry Pi. Using the DHT11 temperature sensor with the Raspberry Pi is a great way to get temperature and humidity readings in your projects. Especially to keep tabs on how hot your Raspberry Pi is, if […]
