It’s fair to say that building electronic gadgets is easier now than it ever has been in the past. With low-cost modular components, there’s often just a couple dozen lines of code and a few jumper ...

Never one to pass up the recycle pile at work, [Scott] usually doesn’t find much. A few old hard drives, maybe a ancient laptop every once in a while, but on very rare occasions he finds something ...

Rohm Semiconductor has developed an evaluation kit for motor driver devices which is designed as a ‘shield’ to plug directly into the Arduino open source board. There different versions of the kit for ...

grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...

High-speed CNC or Computer Numerical Control machine is an ideal solution to cutting labor costs and getting the job done in less time. With so many expensive CNC systems out there in the market, John ...

Stepper and servo motors have different attributes when considered for motion applications. Torque curves play an important role in selecting the proper size and type of motor for an application.
