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?

The post World of Light – an interactive feedback map appeared first on Raspberry Pi.

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…..
