[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, [...]

Flashing LEDs for a persistence of vision display are on bicycle wheels, alarm clocks, and even light painting sticks to draw images in the air. What if you wanted to plot an image in the air (translation) with a single LED? That’s what [acorv] did after taking a cue from a polar plotter. Like the polar plotter and [...]

[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 [...]

This pen plotter, held together with structural epoxy, is an amazing piece of engineering, and almost as impressive as a bridge made entirely out of Bondo. [Brian] at the Rochester, NY hackerspace Interlock needed to build something for the BarCamp geek “unconference.” To lure BarCamp attendees over to the Interlock table, they needed a small [...]

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.  [...]

Although some may have heard of a machine like this, the CNC tripod remains an unknown machine to many in the engineering word.  This particular machine is set up as a plotter, drawing incredibly straight lines, shapes, and letters. The machine appears to have 6 servo motors, 3 working as pairs.  This would simplify control [...]

[Jerry] has been wanting to put together a whiteboard plotter for some time and just recently got around to building one. The plotter draws pretty much about anything he can imagine on a white board measuring just shy of 2′ x 3′. The design first started off with a Basic Stamp board at the helm, [...]

[Hubert] sent in his experiments using HDDs, CDROMs, speakers, and other components to make an XY laser plotter. Those carefully reading will note, its not all three to make one plotter, but rather three plotters each using a separate system. The setups have their advantages and disadvantages, and [Hubert] is sure to point them out; [...]

Get a quick fix of CNC for the day with this plotter. [Francisco Dulanto] grabbed the cartridge carriage from an old inkjet printer and turned it into a gantry by mounting it on two drawer sliders. The optical head assembly from a cd-rom provides the Z-axis movement with the whole thing controlled by three RepRap [...]
