Using Arduino on industrial digital printing machines

on Friday, July 5, 2013

Arduino goes industrial

Most of the projects we’ve been featuring on this blog are  happen to be focused on diy approaches around music, design, art. We are  noticing that more and more people are starting to realize the benefits of using Arduino also in  industrial settings.

Today I’m going to highlight a project posted by Paul M Furley on his blog and describing how back in 2009 he worked in a  family firm, producing the user operator software for their new digital printing machine and decided to use Arduino in high-tech manufacturing:

 I’d been hacking around with Arduino since my masters project and it came along at a perfect time for JF Machines. They had just developed their new ink circulation system: a serious affair with 5 separate ink bottles rising and falling to alter  pressure along with precise temperature control. They needed a way to drive the bottle lifting motors, read in alarm signals and switch inputs as well as output various flashing sequences for the benefit of the operator. Although a PLC would have been suitable, Arduino seemed like a great option.

Since then he realized why he made the right choice  and lists a number of the reasons useful to explore.

You can read the complete story on  his page, here’s just a couple of the most interesting benefits:

Supply security – even if Arduino stopped supplying boards tomorrow, other manufacturers are making clones, and the hardware design lives on. If Arduino changed their physical design, it wouldn’t be much trouble to make a converter to adapt the new and old sockets – in fact, someone would probably release it was an off-the-shelf project as soon as the announcement was made! In the worst case scenario, JF Machines could manufacture the whole Arduino board from the designs for as long as the a compatible microcontroller remained available.

Low cost – I often hear the opposite argument when discussing Arduino with the hobby and hacker scene. I agree that for integrating into a consumer product, the Arduino’s off-the-shelf price is fairly expensive (although good luck designing and making a small batch yourself for cheaper…). However when integrated in a five-figure industrial printing machine, the cost comes close to zero, especially when considering the PLC alternative and the support benefits. If JF Machines were ever to mass-produce their machines, reducing the price of the Arduino would be fairly low on the list of priorities!

Knitic project, or how to give a new brain to knitting machines

on Wednesday, June 5, 2013

knitic - Varvara&Mar

Knitic is an open source project which controls electronic knitting machines via Arduino. To be more precise, Knitic is like a new ‘brain’ for the Brother knitting machines allowing people to create any pattern and modify them on the fly. Knitic kit is composed by an Arduino Due, a diy printed circuit board on top of it, connected to the electronic parts of the original machine, (like end-of-line sensors, encoder, and 16 solenoids) and a software to control the needles real-time.

In the past days I interviewed Varvara & Mar, the duo who developed the project. They’ve been working together as artists since 2009 and their artistic practices lay at the intersection between art, technology, and science. When I run into their project I immediately liked their approach as they see knitting machines as the first real domestic fabrication tool, that has been  overlooked in the age of digital fabrication.

Check the tutorial above and then below some answers to the questions I sent them.

How come you got interested in knitting?
Everything started in January 2012. We had an idea to knit poetry from spam emails. Hence, we were invited to the 3-month-long residency at MU gallery in Eindhoven and 1-month residency with solo exhibition at STPLN in Malmö,  to develop our project. After seeing MAKE magazine article on hacked knitting machine by Becky Stern, we thought it’s easy and fun to do the hack. Well, we had a bit underestimated the complexity of the project, but finally made more than one knitting machines work and started also Knitic project.

How and why did Arduino become useful to your project?
Arduino is A and B in our work. It means we use Arduino for many purposes, and to be honest, we don’t imagine our lives without it.
We applied Arduino already in our first hack of knitting machines, when floppy emulation script didn’t work for us, since we had 940 and not the 930 machine. Hence, we connected all buttons of knitting machine keypad to Arduino and were able to program knitting machine automatically.
In terms of Knitic, Arduino has a key role, because it gets the outputs of sensors, energize the right solenoids according to the pattern, and communicates with Knitic program written in Processing.

Some weeks ago you were at Maker Faire in Newcastle : which type of people got interested mostly about Knitic? 
Interestingly, the most interested group of people were Dutch educators and the ones connected to creative industries. Also people from local hacklabs were very interested.

In some of your presentations you said that knitting and some other more crafty practices are a bit overlooked by fablabs and makerspaces, why do you think is it like that? Is it a matter of gender balance or there’s something more?
We think it is mainly because of the gender and also because MIT, where the  concept of fablab comes from, is dominated by engineers and architects, who saw more potential in hard-surfaced object fabrication, like 3d printing, laser cutting, CNC, etc. Plus there is not much information about hacking and developing open source knitting or sewing machine online. But we hope that things are slowly changing and soon lots of makerspaces will have knitting machines and other tools for handcraft. Hence, we think Knitic is an important example for re-empowering crafts with novel digital fabrication approaches.

I have a knitting machine at home and I realized you need a lot of patience to make it work, but then it’s fun. Do you think that these hacks could lower the barriers and make it more attractive to less nerdish types?
We don’t think that knitting requires more patience than 3D printing, for example. To be honest, with knitting one is able to achieve first results much faster than with a 3D printing machine. To learn a new skill always requires some time investment.

In your opinion, what type of micro-business connected to these knitting machines could flourish in the next years?
Good question. Definitely, custom made knitwear. At the moment, there are no services which are offering knitwear (sweater, scarf, etc) with your own pattern and letting you chose the yarn type. There could be also  lots of interactive knitting and unique pattern generations. For example, we are working on a project called NeuroKnitting right now.
Soon we’ll make more information available on it. In addition to that, there is another business option that is open hardware in the form of Knitic Kit (pcb and components) or, why not, the whole knitting machine.

Thank you!
