Make an Impression at the Bar with a CNC Coaster Plotter

Posted on by

If you’re anything like us, your success with the opposite sex at the bar wasn’t much to brag about. But imagine if you had only had this compact CNC polar plotter and could have whipped up a few custom coasters for your intended’s drink. Yeah, that definitely would have helped.

Or not, but at least it would have been fun to play with. This is actually an improved version of [bdring]’s original “Polar Coaster”. Version 2 is really just a more compact and robust version of the original. The new one has a custom controller for the steppers and pen-lift …read more

Maze Generator Keeps Plotter (and Kids) Busy

Posted on by

We can tell that [Jon Howell] is our kind of guy. After updating his vintage 1985 Hewlett-Packard plotter with WiFi and the ability to load SVG files, he obviously needed to find a bunch of stuff to run off with it. Gotta justify those hacks somehow. So he doubled down and decided support a hack with another hack by writing a maze generator to keep his plotter well fed. He was kind enough to unleash his creation on an unsuspecting Internet as an open source project, and now we all can benefit from a couple of reams worth of mazes. …read more

Vintage Plotter Turned Fruit Spectrometer

Posted on by

Fruit can be a tricky thing: if you buy it ripe you’ll be racing against time to eat the pieces before they turn into a mushy mess, but if you buy the ones which are a bit before their prime it’s not always easy to tell when they’re ready to eat. Do you smell it? Squeeze it? Toss it on the counter to see if it bounces? In the end you forget about them and they go bad anyway. That’s why here at Hackaday we sustain ourselves with only collected rainwater and thermo-stabilized military rations.

But thankfully Cornell students [Christina …read more

Mug-O-Matic Plots On Coffee Mugs

Posted on by

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

The 3D Printed Plotter You Didn’t Know You Needed

Posted on by

We’ve been seeing an influx of repurposed 3D printers recently. Thrifty hackers have been leveraging cheap 3D printers as a way to bootstrap their builds, on everything from laser engravers to pick and place machines. There’s nothing wrong with that, and honestly when you can get a cheap 3D printer for less than the cost of the components separately thanks to the economies of scale, you’d be foolish not to.

But there’s still something to be said for the classic RepRap mentality of building things using printed parts and smooth rods. Case in point, the largely 3D printed plotter that …read more

Knock Your 3D Printer Down To 2D

Posted on by

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

Posted on by

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

Posted on by

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

A Polar Coordinate CNC Plotter Even Descartes Could Love

Posted on by

Take apart a few old DVD drives, stitch them together with cable ties, add a pen and paper, and you’ve got a simple CNC plotter. They’re quick and easy projects that are fun, but they do tend to be a little on the “plug and chug” side. But a CNC plotter that uses polar coordinates? That takes a little more effort.

The vast majority of CNC projects, from simple two-axis plotters to big CNC routers, all tend to use Cartesian coordinate systems, where points on a plane are described by their distances from an origin point on two perpendicular axes. …read more
