For years the proprietary spline pattern of rc servos has been a dealbreaker for hobbyists who want to add custom shafts and gears to their servos. First, different servo sizes have different spline ...

Our open source community invites anyone with an idea to build upon the works of those who came before. Many of us have encountered a need to control linear motion and adapted an inexpensive hobby ...

Having a robot-building hobby just got a lot more dangerous to fingers and wieners now that the RX-64 Smart Actuator is on the market. According to the product page, these beasts can provide “888 ...

Driving hobby servos using a PIC microcontroller is the main goal of this project which can also be used in other microcontroller projects. The control signals of servo include a red wire, a working ...

Tower Pro’s MG90S metal gear micro servo may be the most widely used RC hobby servo today. This is a tiny and lightweight servo with high output power, and its ...

I was looking at the electronics behind the little Petoi dog robot (right), and noticed a chip I was not aware of before, NXP’s PCA9685. On a deeper delve, I noticed Adafruit also uses it for creating ...

In the 1980s, there was Armatron. It was the robotic arm toy offered by Tandy electronics that started it all. Today, it’s a whole new world. You can control robotic arm kits with an Arduino, ...
