If you have an original arcade machine, it may have a mechanical (sometimes called spinning) hard drive inside it. If it hasn’t happened already, these mechanical arcade hard drives will eventually fail. When this happens you will lose all of your game software and your arcade game will essential become a brick, unable to be […]
If you’re a maker, or at all into hobbies that require measuring things, a fraction to decimal conversion chart come in very handy. These charts allow you to quickly convert between fractions and their decimal equivalents in both inches and millimeters (imperial and metric). Fraction to Decimal Conversion Chart We’ve created this awesome and super […]
There are a lot of cool Raspberry Pi projects out there, and you can hardly go wrong in pursuing any of them. But if there’s one Raspberry Pi project that is nearest to the hearts of casual D. I. Pi-ers, it’s the RetroPie. For the price of a Raspberry Pi, power supply, Micro SD card, […]
When building a GPU based mining rig, our research shows there is a lot of misinformation going around that makes it difficult to decide what to purchase. This has a lot to do with the nature of mining. Its something that just about anyone with a little cash can do, if they can follow directions […]
In this article we’re going to cover multimeters! We’ll talk about how to use them to measure voltage, current, resistance, and continuity. We’ll go over what to look for in a multimeter, where to buy one, and give you our picks for the best multimeters you can buy. Deciding Which Multimeter to Buy? In today’s […]
In this tutorial we’re going to learn about using a 555 timer in monostable mode, but first a little history is in order! Without a doubt the 555 timer is one of the most common, if not the most common integrated circuits used on electronics over the last 45+ years. First entering production in 1971 […]
In this tutorial we’re going to learn about using a 555 timer in astable mode. We’ve talked about the longevity of the venerable 555 timer and how its been around for almost 50 years at the time of this writing.

In this Arduino limit switch tutorial, we’re going to talk about how to use the limit switch within our Arduino projects. The limit switch is a fantastic tool for use in projects that have motion control and automation. The limit switch can be used to tell the Arduino that a stop point has been reached. […]
The Arduino force sensor is a super neat sensor that you can use in your projects to measure if something is being pressed upon and to what degree. The force sensor is used in many devices that you might not expect. For example the drum pad! When you tap on a drum pad there is […]
Arduino RGB LED configuration! That’s what we’re covering in this tutorial! Most of the time you will be using LEDs that are a single color. Red, green, or blue for example. an RGB LED is basically three LEDs in one that can produce many thousands of colors! Please note this tutorial is not about WS2812b […]
