[Matt Bell] sends a shout-out to Hackaday by creating a light-painting of our logo with his string plotter. He starts off by setting up a pair of stepper motors which each have a spool to wind and unwind a string. The plotter is made by suspending a stylus between these two strings. In this case, [...]

[Patrick] decided to make a computer controlled etch-a-sketch. While the idea is not that new, there is always a different way to accomplish a goal. An Arduino is used to control a pair of stepper motors which were sourced for pretty cheap, and even came with their own driver. Next a stand was mocked up [...]

For most of the past year, [Joel] has been working on converting a manual mill to a CNC mill with the addition of a computer, brackets and stepper motors. He’s put an amazing amount of effort into his project, and the result is awesome and much less expensive than buying and shipping an old Bridgeport mill. [...]

If you’ve been reading Hack a Day for long enough, you know about our infatuation with stepper motors. These precious little devices put the oomph into our CNC routers, 3D printers, robots, and other miscellaneous projects. Steppers aren’t your run-of-the-mill motors, though. [Steaky] posted a great introduction to stepper motors that lets you hit the [...]

[Euphy] just posted and Instructable of his Polargraph drawing machine that’s able to draw huge images slower than molasses in November. The plotter only uses two stepper motors to control the position of the pen and can be made nearly entirely from salvaged parts – [Euphy] built his for just about £150. The Polargraph uses [...]

We think this is an intriguing take on half-tone art. It’s a CNC machine that uses an Arduino and two stepper motors to draw on a paper-covered drum. But you’re not just going to set it and forget it. To simplify the device, the Z-axis is not mechanized, but requires the dexterous opposing digit of a [...]

[James] built himself a robotic band from obsolete computer parts. The band needed something to play, and [Marilyn Manson]‘s Beautiful People fit the bill. While it’s not the Rock-fire Explosion, having the [James]‘ band cover [Marilyn Manson] is nearly as terrifying. [James]‘ original plan was to cover Mad World, but the stepper motors were drowning [...]

The plotter featured above was, according to the author, made almost entirely of salvaged parts. In addition to what he had accumulated, only $20 in parts was needed to complete this build. Pretty good considering the thousands of dollars that a new plotter goes for. Control of all axes is accomplished using unipolar stepper motors.  [...]

[Reza Naima] has been using an Arduino as the center of his CNC setup for quite some time now. It handles three stepper motors, limiting switches, e-stop, and spindle control. The sketch he’s using allows him to stream g-code to the popular prototyping platform, freeing him from needing a dedicated PC. It’s worked so well [...]

This robot artist, the Drawbot, produces images using an Arduino and Processing. A piece of paper is attached to a wall as a stylus connected to a couple of stepper motors scribbles out patterns that gradually become the image seen above. Each drawing is different and can take several weeks of constant operation to finish. [...]

[Robert Pickering] shares his automated guitar pickup winder with us. He built it for his senior project at Old Dominion University. Two stepper motors are used to wind the magnet wire around the pickup hardware. The unit is PIC based and about six minutes into the video (embedded after the break) you can see that [...]

This table-top extruder was modeled after the Makerbot. Instead of laser-cut wood this is built from acrylic, uses salvaged rods from laser printers, some inexpensive stepper motors, and a homemade extruder. All said and done, [Peter Jansen] figures this build came in somewhere around $200-300. It may not look as nice, but at half the [...]
