The CNC Wood Burner turning heads (and wood, obviously)

via Raspberry Pi

Why stick to conventional laser cutters or CNC machines for creating images on wood, when you can build a device to do the job that is a beautiful piece of art in itself? Mechanical and Computer Science student and Imgur user Tucker Shannon has created a wonderful-looking CNC Wood Burner using a Raspberry Pi and stepper motors. His project has a great vinyl-turntable-like design.

A CNC Wood Burner?

Sure! Why not? Tucker had already put the knowledge he acquired while studying at Oregon State University to good use by catching a bike thief in action with the help of a Raspberry Pi. Thus it’s obvious he has the skills he needed to incorporate our little computer into a project. Moreover, his Skittles portrait of Bill Nye is evidence of his artistic flare, so it’s not surprising that he wanted to make something a little different, and pretty, using code.

With an idea in mind and sketches drawn, Tucker first considered using an old record player as the base of his build. Having a rotating deck and arm already in place would have made building his project easier. However, he reports on Imgur:

I thought about that! I couldn’t find any at local thrift shops though. Apparently, they’ve become pretty popular…

We can’t disagree with him. Since his search was unsuccessful, Tucker ended up creating the CNC Wood Burner from scratch.

Taking into consideration the lumps and bumps of the wood he would be using as a ‘canvas’, Tucker decided to incorporate a pivot to allow the arm to move smoothly over the rough surface.

The code for the make is currently in ‘spaghetti form’, though Tucker is set to release it, as well as full instructions for the build, in the near future.

The build

Tucker laser-cut the pieces for the wood burner’s box and gear out of birch and pine wood. As the motors require 12v power, the standard Raspberry Pi supply wasn’t going to be enough. Therefore, Tucker scavenged for old computer parts , and ended up rescuing a PSU (power supply unit). He then fitted the PSU and the Raspberry Pi within the box.

The cannibalised PSU, stepper motor controller, and Raspberry Pi fit nicely into Tucker’s handmade pine box.

Next, he got to work building runners for the stepper motor controlling the position of the ‘pen thing’ that would scorch the image into the wood.

After a few test runs using paper, the CNC Wood Burner was good to go!

The results

Tucker has used his CNC Wood Burner to create some wonderful pieces of art. The few examples he’s shared on Imgur have impressed us with their precision. We’re looking forward to seeing what else he is going to make with it!

Your turn

Image replication using Raspberry Pis and stepper motors isn’t a new thing – though doing it using a wood-burning device may be! We’ve seen some great builds in which makers set up motors and a marker pen to create massive works of art. Are you one of those makers? Or have you been planning a build similar to Tucker’s project, possibly with a new twist?

Share your project with us below, whether it is complete or still merely sketches in a notebook. We’d love to see what you’re getting up to!

Arduino Uno-driven plotter uses rulers for arms

via Arduino Blog

When you see a plastic ruler, you wouldn’t normally assume it was destined to become part of a CNC plotter. Maker “lingib,” however, realized their potential to be combined to form plotter arms, in this case actuated by two stepper motors.

The resulting build can expand and contract the resulting shape, allowing a pen at the end point of the two sets of rulers to move back and forth across a piece of paper. Necessary spaces in the plot are provided by a micro servo that can lift the pen/ruler off of the writing surface.

The device is powered by an Arduino Uno, which controls the two NEMA 17 stepper motors via a pair of EasyDriver Modules. You can find more details about how to create one of these, including code and how the geometry behind it works, on its Instructables page.

A how-to on making a 2 axis, G-code controlled drawing plotter from TheSuperSewcio, project instructables here:

Here I’ll show you how to make 2 axis, gcode controlled drawing plotter.
I’ve already made a delta 3D printer which is awesome, the only thing that wasn’t made by me was the Arduino program. This program was very long and complicated, so I’ve downloaded it from the Internet. I’ve started to think if I am able to also make it myself. But why should I start with something so hard, firstly let’s make something easier – Plotter!

World of Light – an interactive feedback map

via Raspberry Pi

Using a self-written API, Joshua Krosenbrink gifted the new Usabilla office with the World of Light, a 426 RGB LED-powered map of the world.

World of Light

The API pushes user location information to a Raspberry Pi, animating the LEDs in real time to respond to website feedback as and when it’s received by the company.

World of Light

Nice LED wall I built with 426 RGB LEDs and a Raspberry Pi with WIFI. Renders live user feedback that comes in from all over the world by pulling data from the public API. A ‘little’ present for in the new office.

Joshua spent a decent amount of time using a CNC machine to drill the 426 holes needed, while distributing 30 amps of power to produce the beautiful effect.

More photos of the build can be found at the project’s Hackaday page. While we figure out what we could use this map for at Pi Towers, why not tell us how you would use one in the comments below?

Bob Davis has been working on rebuilding his DIY CNC machine:

I have been busy rebuilding my DIY CNC machine. It will be all metal when I get done. It will also include a USB interface, likely an Arduino. None of my computers have a parallel port these days. So something has to be done to resolve that issue.
This first picture is the new metal parts all drilled and ready for assembly. Well maybe ready to be filed so they can be assembled…..
