For an older standard, MIDI has remarkable staying power in the music industry. It remains the de facto digital interface between computers and instruments thanks to its open nature, but …read more Continue reading High-Resolution MIDI Controller
Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen …read more Continue reading Linear Power Supply’s Current Limiter is a Lesson in Simplicity
[Cranktown City] uses a number of custom-built linear rails used as gantries for various tools in the shop. The first is on a plasma cutter, which is precise but difficult …read more Continue reading Icicle Patterns With Custom Gantry
Every once in a while we stumble across something so simple yet so clever that we just have to call it out. This custom linear Hall effect sensor is a …read more Continue reading Clever Mechanism Makes a Linear Control from a Rotary Hall Sensor
Statistics often gets a bad rap in mathematics circles for being less than concrete at best, and being downright misleading at worst. While these sentiments might ring true for things …read more Continue reading Using Statistics Instead of Sensors
[Mark Smith] must really, really like his coffee, at least judging by how much effort he’s put into tricking out his espresso machine. This inductive water tank sensor is part …read more Continue reading Extreme Espresso, Part 2: An Inductive Water Level Sensor
Most experiments in flexible robot actuators are based around pneumatics, but [Ayato Kanada] and [Tomoaki Mashimo] has been working on using a coiled spring as the moving component of a linear actuator. Named the flexible ultrasonic motor (FUSM), [Yunosuke Sato] built on top of their work and assembled a pair …read more
We around the Hackaday shop never get tired of seeing new ways to mark the passage of time. Hackers come up with all manner of interesting timekeeping modalities using every imaginable material and method of moving the mechanism once per whatever minimum time unit the hacker chooses to mark.
But …read more

On the face of it, making a clock that displays the time by moving a pointer along a linear scale shouldn’t be too hard. After all, steppers and linear drives should do the job in a jiffy. Throw an Arduino in and Bob’s your uncle, right?
Wrong. At least that’s …read more
Here at Hackaday, we pride ourselves on bringing you the freshest of hacks, preferably as soon as we find out about them. Thanks to the sheer volume of cool hacks out there, though, we do miss one occasionally, like this e-waste horizontal CNC mill that we just found out about. …read more
