First of all, what exactly is a servo? A servomechanism is technically any automatic device that can correct its own position based on negative feedback. Negative feedback is the process by which electrical signals are fed back in a manner that ultimately reduces further fluctuations. Servo motors can rotate or push components with amazing accuracy using this method.
Choosing the right tool for the job is arguably the most important step in the planning process of any project. While it may not seem like something you really need to plan for, having a good pair of wire strippers at the ready will save you a lot of hassle when the time comes that you actually need them.
So, you're about to start a project. You have your materials list and you're following it by the letter. But when you get down to the bottom of the checklist, all it says is "nails." Before you start to panic and hit the forums, take a deep breath and check out this quick guide to some common questions about nails. Don't worry, it's never as hard as you think it will be.
“This is just… This is just soft foam and duct tape. It can’t harm anyone.“ Role Models (2008) Choosing the right foam for your costume/prop is probably the first big choice you’ll make in the process. It’s important to know what you want your piece to look like and how you want it to behave […]
“Do you think I’m a fool? That the Commander doesn’t know every bolt- every weld- in his ship?” Galaxy Quest (1999) Did you know you can get a general idea of how strong a bolt it just by looking at the head? It may not apply to every bolt, but it does apply to most. […]
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.
