Putting Projects in Motion with the 555 Timer IC
Our latest project uses an array of parts to build three separate breadboard projects. Follow along as we put Projects in Motion, showing you how to control three different motor types with little more than a few components, wire, and a power source.
Tool Review: NEMA 23 Stepper Motor Covers
Over the last year I have been finishing a project to convert my X2 manual mini mill into a fully enclosed 3-axis CNC milling machine. Once I had the stepper motors mounted and running, I worried that the wire connection at the base of the motors might be a potential weak point in the design. Eventually I want to use mist coolant when machining parts but I do not want to run the risk of shorting out the wiring due to spotty connections.
How-To: Use a Stepper Motor as a DC Generator
MAKE pal Dino Segovis brings us this handy tutorial on running a stepper motor in “reverse,” i.e. turning the shaft mechanically in order to generate electrical power, instead of the normal usage. He writes: Any electric motor will also output a voltage when it’s freely spinning. Stepper motors are much better at this because they […]
