Nema 17: all about the Arduino compatible stepper motor

Nema 17

We have already analyzed everything about the stepper motors that you can use with your Arduino projects, but there is one of those engines that stands out from the rest of the models like the Nema 17, since it is a very precise engine with several applications, among them replacing the broken engine of some 3D printers.

With this stepper motor you will be able to control very precisely the rotation of its axis to make precision movements and thus control the movement of your machine or robot. And in this guide you will get all the information you need to know it closely and start working with it.

Arduino Mega: all about the big development board

Arduino Mega


If the Arduino UNO Rev3 board is too small for you and you want to create more advanced projects and enjoy more power, then what you are looking for is an Arduino Mega board, another of the available models created by the same developers as the original board, but with a faster microcontroller, more memory, and more pins for programming.

Arduino Mega has many similarities with Arduino UNO, but there are some differences that make it very special for all the makers who are looking for something more. Usually, if you are starting out it is not the best choice, but it is if you have already exploited the capabilities of UNO and want to go further.

Create a homemade Nerf gun with step-by-step and crazy modifications

Nerf gun

NERF is a registered trademark for toys. It was created by the Minnesota-based Parker Brothers company in 1969, but is now owned by the Hasbro company. Most of these toys are plastic weapons that can launch foam rubber projectiles or rubber arrows that do not hurt and especially designed for children or not so children .

These kinds of weapons can be bought and are cheap. But you can also create your own Nerf gun or rifle as we will explain here step by step. In both cases, it will be cheap, but the good thing about creating one yourself is that you will have greater ability to modify it to your liking. Many people create them to emulate some weapons from their favorite movies, comic book heroes, etc.
