Re: [oshug] Arduino help needed
by Paul Tanner 05 Jul '13

Hi Guys, I cheated and used node.js with a module called node-serial. I discovered that you need to disconnect the serial port from the console before you can use it (edits to /etc/inittab and /boot/cmdline.txt). I imagine you'd need to do this in a python environment too. minicom was very useful for prodding the serial device to make sure it was working before I pointed my program at it.

Arduino help needed
by Jeremy Bennett 04 Jul '13

04 Jul '13

I need some help from one of you Arduino gurus. I want to talk to the Arduino serial interface from a Fedora Linux system. I know how to do the Arduino side, using Serial.available, Serial.read, Serial.write etc. My problem is how to talk from the Linux end. All the examples I see are Windows based and use Thierry Schneider's Serial C++ Library for Win32. What do I use as the Linux equivalent? It's not as simple as just writing the the Linux device (in this case /dev/bus/usb/004/081). I suspect I need something rather cleverer, but I don't know what it is. Any help much appreciated. I'm trying to help a youngster set up an Arduino based face tracker, driven by OpenCV face detection on the Linux box. Thanks, Jeremy -- Tel: +44 (1590) 610184 Cell: +44 (7970) 676050 SkypeID: jeremybennett Twitter: @jeremypbennett Email: jeremy.bennett(a)embecosm.com Web: www.embecosm.com

Arduino compatible FPGA shield on Kickstarter
by Roy Bunce 14 Jun '13

14 Jun '13

Hi, You might be interested in my project recently launched on Kickstarter,com (short URL http://kck.st/164ObLg ) . It uses a MACHXO2-1200 from Lattice, and includes USB programming logic, so no external programmer is required. It's a relatively simple board, aimed at beginners, and will be supplied ready programmed with a I2C driven I/O expander. The associated web site will include tutorials to explain how to download and use the free Lattice design tools, as well as giving some simple design examples. By following these examples, the new FPGA user will be able to gain confidence and experience by modifying known working VHDL/Verilog code. The schematic and pcb design is in DesignSpark format, and will be released if the Kickstarter project is fully funded. Thanks for reading this, Regards, Roy Bunce

OSHUG #27 — Boards (Beautifully Functional Circuits, Little Printer), Thursday 20th June.
by Andrew Back 04 Jun '13

04 Jun '13

Hello, Registration is now open for the June OSHUG meeting, details of which are below. Cheers, Andrew // Event #27 — Boards (Beautifully Functional Circuits, Little Printer) Thursday 20th June 2013, 18:00 - 20:00 at Centre for Creative Collaboration, 16 Acton Street, London, WC1X 9NG. Sponsored by SolderPad: http://solderpad.com Registration: http://oshug.org/event/27 At the twenty-seventh meeting there will be a talk on designing printed circuit boards that are aesthetically pleasing as well as functional, and a talk on the design and manufacture of the Little Printer, and the upcoming BERG Cloud dev board. - Beautifully Functional Circuits Circuit design is typically thought of as block-based and purely functional; it doesn't necessarily have to be. Our inherent creativity as engineers has been dampened by unimaginative and limiting design tools, that have forced us to "forget" that functional circuits can, and should, be beautiful too. This talk will explore these limitations and how we could do better. Saar Drimer is an experienced hardware engineer. In the past few years he's been developing tools for effective and efficient hardware design. - Little Printer In 2012 the design and product company BERG launched Little Printer, their internet-connected thermal printer that prints its own face. It was the first consumer product that BERG had made, and went on to be nominated for the 2013 Designs of the Year by the Design Museum. In this talk we will explore the project's evolution, from prototype to mass produced product. The talk will cover the way BERG's design process works, going to China to organise plastic injection moulding, passing certification and EMC, and many other practical aspects of making and selling consumer products that connect online. The talk will also cover a technical overview of the whole stack that brings Little Printer to life, the extraction and evolution of the underlying BERG Cloud platform, and the forthcoming developer kits that open up the platform to anybody. Nick Ludlam is CTO at BERG, and is responsible for the collective software development, from the embedded code running inside Little Printer, the Ruby/Rails-based cloud architecture, and the use of Amazon Web Services to scale. Andy Huntington is Hardware Producer & Designer at BERG and is responsible for all of BERG's physical hardware, from the electronics and PCBs to the industrial design and manufacturing of Little Printer itself. He has a background in music and moved through software into hardware following an Interaction Design MA at the Royal College of Art. Note: Please aim to arrive for 18:00 - 18:20 as the event will start at 18:30 prompt. Registration: http://oshug.org/event/27

London Arduino Jam + video circuit bending - 13th May
by marc barto 06 May '13

06 May '13

Hi all We're back for another evening of presentations and informal discussions around Arduino at the Hub Westminster on 13th May.<http://www.meetup.com/LondonArduino/events/114960302/> With our usual programme of project demos, news and jam, we'll also have our friend Fabrizio presenting some video circuit bending devices built during a recent workshop at London Hackspace. Not exactly Arduino stuff as the devices (video mixer and others) are from the 80's but still very much hardware hacking! (more info here<https://www.facebook.com/events/132142510308604/> ). The event is of course free, all info here: http://www.meetup.com/LondonArduino/events/114960302/ Hope you can join us Marc @marc_in_london <https://twitter.com/marc_in_london>

Electromagnetic Wave Event & Whitespace Spectrum
by Ben Ward 27 Apr '13

27 Apr '13

Hello OSHUGgers, I hope this is an acceptable announcement for this list. Electromagnetic Wave (May 5th) is a day filled with talks and workshops for those with an inquisitive mind or an interest in making things, held on a converted East German fishing vessel moored in London. https://www.emfcamp.org/wave Talks so far include Zeppelins, Wifi radar, open-source vacuum cleaners and WebGL. As part of the team getting Internet to the boat (harder than you might imagine) I've also managed to get a TV Whitespace licence for experimenting. Whitespace will soon be open for us all to use, and is particularly interesting for the Internet of Things. As the country's (world's?) first "popup" whitespace network what we're looking for is experiments, interested people, Internet of Things ideas or skills. Read more about it here: http://love-hz.com/post/48999576581/emw-event Hope you can join us or even just offer ideas Ben -- ben(a)crouchingbadger.com | h <http://www.crouchingbadger.com/>ttp:// love-hz.com

Save the date!
by Andrew Back 25 Apr '13

25 Apr '13

Hello, So this year's annual two day event will again take place in Hebden Bridge, and over the weekend of 14th and 15th September. We're aiming to do something bigger this time, that will have hardware and web tracks, and with a theme of "making things". So, stories about making hardware or a web thing, and mostly from an end-to-end perspective. Some talks will be on projects that combine web/online and hardware too. We'll be taking over most of the Town Hall [1] for the entire weekend with, as before talks on the Saturday and workshops on the Sunday. We'll have 2, possibly 3, spaces to use on the Saturday, and 2 on the Sunday. With one of these being the very lovely Waterfront Hall. There will be a social on the Saturday evening, also at the Town Hall, and if the weather is good we might even have a marquee out on the patio that overlooks the river. Cheers, Andrew [1] http://www.guardian.co.uk/uk/the-northerner/2012/aug/13/hebden-bridge-town-…
