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. 

World of Light Map

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…..

FarmBot, the open-source CNC farming robot

via Raspberry Pi

What do you imagine the future of farming to look like? The FarmBot team, located along the California coast in San Luis Obispo, is exploring just that. The team has set out to create humanity’s first open-source CNC farming machine to put the power of polycrop farming into the smallest of spaces.

No Title

No Description

The FarmBot structure fixes directly on top of any standard raised planter box. You can think of it like a 3D printer, but instead of extruding plastic, the tool head deposits seeds, delivers water and rids the box of weeds, all by moving across a gantry. Powered by a Raspberry Pi 3, an Arduino Mega and a motor control shield, the FarmBot brings agricultural automation within the reach of the committed hobbyist.

FarmBot Electronics

FarmBot’s interchangeable tooling set is impressive and has been carefully designed so that you may print tools with any hobbyist-level 3D printer.

The universal tool mount features 12 electrical connections, three liquid/gas lines and magnetic coupling. Ready-to-print attachment tools include the seed injection mount, the water nozzle specially designed for efficient watering, and the weed suppression tool which detects and destroys weeds at the root. FarmBot has documented detailed technical specifications of the universal tool mount, to encourage community members to design additional custom mounts that are specific to their particular farming needs.

Check out the tech specs of the tooling attachments for further nerding out!

FarmBot’s drag-and-drop web-based platform allows you to design and build your planter box farm easily. No coding is required; in fact, it has an almost game-like interface. Once your design is complete, the sequence builder and scheduler will help to allocate appropriate care to each plant.

Web-App-on-Different-Devices

It’s evident from looking at the design structure, documentation, CAD files, and detailed BOM that the creators of the FarmBot took to heart the idea of open source. By selecting off-the-shelf products and tools, they ensured this system is as accessible as possible. I’m really happy to see the Raspberry Pi 3 at the heart of FarmBot and I can’t wait to see how this community grows.

If you’re someone who’s serious about getting a good crop return from your small space, and you’re as mesmerized by FarmBot as I am, there’s still time to place a pre-order to receive one of the first batches ready to ship in February!
