Buying anything used can be a hassle. Unless you are one of those people who loves buying and flipping other peoples' junk, you probably aren't looking forward to the process. But, then you remember how much money you'll probably save and the hunt begins. Before you jump into the wild world of secondhand tools, let's take a crash course is buying used!
Resistors are a necessary part of any electrical system. They provide the ability to limit current and signal flow, among many other uses. There are numerous different types of resistors, all varying in size and power, but we're going to take a closer look at arguably the most common type- axial resistors.
Woodworking is one of the oldest skilled trades in human history. Along with stone, clay, and animal renderings, wood was one of the most important materials for developing homo erectus. Of course, they didn't have the benefits of world trade and large-scale transportation back then, so most early human ancestors just used what was available. Today, we have access to any type of wood we please, delivered to our door.
Arduino vs. Raspberry Pi: a battle as old as... a few years. Though it isn't really much of a battle since both interfaces provide vastly different experiences. We're going to take a look at some of the similarities and differences between the two and hopefully help you decide which one (or both) is the right fit for your project.
It seems like a pretty simple task, doesn't it? I bet a lot of people (myself included) are confident that they can eyeball a good center point. But eyeballing isn't exact and sometimes you need to be exact. So how does one find an exact center on an existing circle? It's actually not very difficult and there are multiple ways to do it. Here are a few of the simplest methods.
One of the most confusing parts of electronic work is choosing the right wires. If they're too thin, they may not be providing enough power. If they're too thick, they may be taking up precious real estate if you have a densely-packed project. Figuring out the right wires to use also involves a fair amount of math. Let's hope you were paying attention in algebra.
While we are still a long way from rogue artificial intelligence enslaving the human race (at least I hope we are), the necessity for batteries remains largely the same. Batteries power most things in our lives. Phones, watches, cars, tools- all of these things are powered in some part by batteries.
Soldering is probably a lot older than you'd think. It dates back to at least 3,000 B.C. where the Sumer people of Mesopotamia used soldering to assemble their swords. Historically, soldering was used mainly for jewelry, cookware, and stained glass. Today it is widely used in electrical work and electronics.
So, you want to hang that new family photo in the living room, or set up that fancy mirror you got for a steal at your neighbor's garage sale. If the picture frame is light enough, you can probably get away with hanging it wherever it looks good, but most of the time you're going to need to find a stud. And no, I don't mean a tall, dark, handsome man who can solve all of your household problems with a Colgate smile. I'm talking about the vertical wood framing that holds up your entire house.
