Registration open for OSHCamp 2013.
by Andrew Back 25 Jul '13

25 Jul '13

Hello, This year OSHCamp is being run as part of a bigger event called Wuthering Bytes, and details of the OSHUG talks and registration can now be found at: http://oshug.org/event/oshcamp2013 Still waiting to confirm one more! We've got a pretty great line up — and very much in terms of the non-OSHUG (software/web/design) talks too. Much more info will be online in due course at: http://wutheringbytes.com The capacity is slightly higher than last year, but I'm expecting that with 18 talks (across two rooms) on the Saturday alone, demand will be also! As such I wouldn't hang about if you're planning on taking part :o) I would also expect that, like last year, rooms at Hebden Bridge Hostel will go pretty quickly too. Best, Andrew PS. No need to register if you are presenting or running a workshop, of course.

Spaaaaaaaace!

Hi, A friend of mine has set up this meetup: http://citizeninventor.eventbrite.co.uk/ ----- In our first meetup, we will try to whirlwind through what is already do-able and help to motivate you (if you are not already motivated) to get hacking with space. The line up will be announced closer to date. Expect info around CubeSAT and a bit on the wider economy of the space industry! PS: If you or someone you know would like to present or participate in our lightening talks for future events, please get in touch at contactme at citizen inventor dot com. It is the goal of this group to help spread the love and knowledge on space and environment hacking! ----- It looks cool so I strongly recommend it! Regards, @ndy -- andyjpb(a)ashurst.eu.org http://www.ashurst.eu.org/ 0x7EBA75FF

Adrian Bowyer (RepRap), Wed 2nd October.

Hello, Just a quick heads-up that we'll be hosting a joint event with the BCS OSSG in October, at which Adrian Bowyer of RepRap fame will be presenting, along with our very own Alan Wood. The website will be updated in due course, however, registration is now open and as spaces are limited and likely to go quickly, early booking is highly recommended! https://events.bcs.org/book/740/ Cheers, Andrew

It was all much easier than I thought, once I realized that the USB serial terminal is /dev/tty/ACM<n>, not /dev/tty/USB<n> when using Arduino Uno. It is trivial to use stty to set the line parameters and implement a simple C++ class to access the serial line on the host. Code on GitHub at: https://github.com/embecosm/esp9-arduino-facetracker I don't know if the face tracker works yet - the servos are lost in the post. But at least the Uno is getting some sort of serial data.

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.
