Omni Wheels Move This CNC Plotter

We’ve always had a soft spot for omni wheels and the bots that move around somewhat bumpily on them. Likewise, CNC pen plotters are always a welcome sight in our tip line. But a CNC plotter using omni wheels is new, and the results are surprisingly good.

Built from the …read more

Relive The Dot Matrix Glory Days With Your 3D Printer

With the cost of 3D printers dropping rapidly, we’ve started to see a trend of hackers re-purposing them for various tasks. It makes perfect sense; with the hotend and extruder turned off (or removed entirely), you’ve got a machine that can move a tool around in two or three dimensions …read more

Pen Plotter From Salvaged Printer Parts

Like many of us, [Benjamin Poilve] was fascinated when he took apart a broken printer. He kept the parts, but unlike most of us, he did something with them, building a neat little plotter called the Liplo. Most pen plotters work by moving the pen on two axes, but [Benjamin] took a different approach, using the friction drive bars from the printer to move the paper on one axis, and a servo to move the pen on the other. He’s refined the design from its initial rough state to create a very refined final product that uses a combination of …read more

Mug-O-Matic Plots On Coffee Mugs

There is something fascinating about watching an autonomous machine. An automatic car wash, a soda vending machine that picks up the product behind a window, a plotter, or a robot like a CNC or 3D printer are all interesting to watch. Although [EngineerDog] bills Mug-O-Matic as a tiny CNC, we think it is more of a plotter for coffee mugs. It’s still fun to watch though, as you can see in the video below.

The design has about 60 printed parts and uses a Sharpie at the business end. It accepts gcode and can even emblazon your favorite mug with …read more

Knock Your 3D Printer Down To 2D

Hackers love 3D printers. In fact, they might love them a little too much. We hope know we aren’t be the only ones who couldn’t turn down a good deal on an overseas printer (or two). But when you’re not pumping out plastic boats and other PLA dust collectors, what are you supposed to do with them?

Well if you’re like [Uri Shaked] you could hand them a pen and tell them to get writing. The holidays are coming up quick, and somebody’s gotta sign all these cards. In his detailed write-up, he shows how he was able to add …read more

Tiny Plotter Is Made Of Strings And Cardboard

If you’ve been hanging around Hackaday for any length of time, you’ve undoubtedly seen the work of [Niklas Roy]. A prolific maker of…everything, we’ve covered his projects for over a decade now. He’s one of an elite group of hackers who can say they’ve been around since Hackaday was still using black & white pictures. Yet sometimes projects fall through the cracks.

Thanks to a tip sent in from one of our beloved readers, we’re just now seeing this incredible cardboard plotter [Niklas] made for a workshop he ran at the University of Art and Design Offenbach several years ago. …read more

Bot Makes Etch A Sketch Art In One Continuous Line

Introduced in 1960 for the princely sum of $2.99 ($25.00 today), Etch A Sketch was to become a standard issue item for the Baby Boomers’ toy box. As enchanting as the toy seems, it’s hard to see why it had staying power: it was hard for young fingers to twirl the knobs, diagonal lines and smooth curves required a concert pianist’s fine motor control, and whatever drawings we managed to make were erased at the slightest jostle of the tablet.

Intent on righting these wrongs, [Sunny Balasubramanian] not only motorized an Etch A Sketch, but he’s also given it a …read more

Junk Build Printer Uses Pencil To Print

Sometimes, it is interesting to see what you can build from the bits that you have in your junk drawer. [Dr West] decided to build a printer with spare parts including a hard drive, a scanner base and an Arduino. The result is a rather cool printer that prints out the image using a pencil, tapping the image out one dot at a time. The software converts the image into an array, with 0 representing white and 1 representing black. The printer itself works a bit like an old-school CRT TV: the scanner array moves the printer along a horizontal …read more

Extracting A Vector Font From A Vintage Plotter

There is a huge variety of hardware out there with a font of some form or other baked into the ROM. If it’s got a display it needs a font, and invariably that font is stored as a raster. Finding these fonts is trivial – dump the ROM, render it as a bitmap, and voilà – there’s your font. However, what if you’re trying to dump the font from a vintage Apple 410 Color Plotter? It’s stored in a vector format, and your job just got a whole lot harder.

The problem with a vector font is that the letters …read more

Make a Plotter Out of Rulers

Instructables user [lingib] made a clever and inexpensive pen arm plotter that uses plastic rulers for arms. An inspiring sight for anyone without a bunch of robot parts lying around,

The electronics are straightforward, with an Arduino UNO and a pair of Easy Drivers to control NEMA17 stepper motors connected to robot wheels, which serve as hubs for the rulers. At the end of the arms, an SG90 micro servo raises and lowers the pen as commanded, shoving the whole pen assembly off the paper with its horn—an elegant solution to an age-old drawbot problem. He even wrote wrote a …read more
