Open Source Hardware Summit
by Andrew Katz 16 Oct '13

16 Oct '13

You're probably all aware of this, but if not: next year's Open Source Hardware Summit is likely to be in Europe, venue TBC. If you can come up with a compelling reason why Hebden Bridge is the ideal venue (and who can't?) then now is the time to get stuck into the discussion over on lists.oshwa.org. Best Andrew

OSHUG #30 call for talks!
by Andrew Back 08 Oct '13

08 Oct '13

Hello, We're in the process of planning the last OSHUG meeting of 2013, which is set to take place on Thursday 28th November at the offices of Erlang Solutions (thanks, Omer!) The theme that is developing is around re-purposing/over-clocking/reverse-engineering of hardware. As ever, there should ideally be an open source hardware aspect, e.g. over-clocking of OSHW, or perhaps an open source OSHW design for use with a over-clocked, modified or a reverse-engineered product. Although, talks on the wider principles, techniques and approaches etc. are welcome also. I'd like to try and get details together within the next week if possible. Cheers, Andrew

OSHUG #29 — Production by the Proletariat (RepRap, TVRRUG), 2nd October 2013.
by Andrew Back 17 Sep '13

17 Sep '13

Hello, Finally got round to putting up the event page for OSHUG #29. Looking at the BCS registration page there are just 14 tickets left. Cheers, Andrew // Event #29 — Production by the Proletariat (RepRap, TVRRUG) 2nd October 2013, 17:30 - 21:00 at BCS London, 1st Floor, The Davidson Building, 5 Southampton Street, London, WC2E 7HA. Registration: http://oshug.org/event/29 For the twenty-ninth meeting we will be joining forces with the BCS Open Source Specialist Group, to host talks from the creator of RepRap, Adrian Bowyer, and Alan Wood of Thames Valley RepRapUser Group. — The Ownership of the Means of Production by the Proletariat Look at your computer setup. Imagine you hooked up a 3D printer. Instead of printing on bits of paper this 3D printer makes real, robust, mechanical parts. To give you an idea of how robust, think Lego bricks and you’re in the right area. You could make lots of useful stuff, but interestingly you could also make lots of the parts to make another 3D printer. That would be a machine that could copy itself. This talk will be about RepRap – the Replicating Rapid-prototyper. This 3D printer builds the component up in layers of plastic. This technology already existed before RepRap, but the cheapest proprietary machine then would have set you back £15,000. And it wasn’t even designed so that it could make itself. So what the RepRap team have done is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about £300). That way it’s accessible to small communities in the developing world as well as individuals in the developed world. The RepRap machine is being distributed entirely free to everyone using open-source – so, if you have one, you can make another and give it to a friend… Adrian Bowyer holds a first degree and a PhD in engineering from Imperial College. He was an academic at the University of Bath for 35 years. He retired in 2012 to help to run the company RepRap Professional Ltd. Adrian's areas of research are geometric modelling and geometric computing in general (he is one of the authors of the Bowyer-Watson algorithm for Voronoi diagrams), the application of computers to manufacturing, and biomimetics. In 2004 he created RepRap – humanity’s first self-replicating general-purpose manufacturing machine. — Experiences from the Thames Valley RepRap User Group Thames Valley RepRap User Group (TVRRUG) was set up to provide support to those who wanted to build their own RepRap 3D printer, and to exchange information and ideas between those who had already successfully completed builds. TVRRUG has now organised three group build rounds, sourcing and printing parts, and resulting in many working printers. Along the way the group has produced extensive documentation, and designed its own electronics and a variant of the Prusa Mendel design. Alan Wood originally trained in systems engineering, and got lost in software engineering and F/OSS for a decade, before returning back to his hardware roots via the open source hardware and makers movement that has gathered momentum in recent years. Note: Please aim to arrive for 17:30 - 18:20 as the first talk will start at 18:30 prompt. Registration: http://oshug.org/event/29

Circuit Review SE
by Saar Drimer 18 Aug '13

18 Aug '13

Hi All. I feel that this is relevant enough to post here. I've just created a 'Circuit Review' Stack Exchange proposal here: http://area51.stackexchange.com/proposals/58903/circuit-review?referrer=xPQ… I feel that we lack a place where we can post our schematics/layout/BOM and have people review them. This could be very useful for OSHW projects. In order to support this proposal, follow the link above, 'follow' it, suggest questions, and then promote on social networks ;) There's an equivalent site for code review that's already going: codereview.stackexchange.com cheers, saar.

Hello, We'd like to run a soldering workshop on the Sunday for people with little/no soldering experience, at which at they get to assemble the kit mentioned in the previous post. Are there any volunteers for helping out with this? :o) It should obviously be straightforward enough and we're looking to get in 4-5 soldering stations. Cheers, Andrew

OSHCamp board review!
by Andrew Back 07 Aug '13

07 Aug '13

Hi All, Saar has come up with a very cool board design for a kit which is going into the OSHCamp 2013 / Wuthering Bytes goody bag: http://boldport.blogspot.co.uk/2013/08/new-board-wuthering.html This is essentially Ihsan's LittleWire board, re-spun via Saar's PCBmodE, for added wonky track goodness along with other artistic flourishes. Feedback is welcomed and in particular on functional considerations! Cheers, Andrew

Open Hardware Jam
by Mark Johnson 07 Aug '13

07 Aug '13

Hello OSHUGgers! I'm one of the organisers of OggCamp, an annual free culture unconference that's now in it's 5th year, and will be taking place at LJMU in Liverpool on the 19th and 20th of October. Last year we had a sort of sub-event called the Open Hardware Jam (which some of you may be a part of, I'm not sure). OpenLabs, the group at LJMU who hosted the event, did a lot of the organising for it but dont have the resources to organise it this year (and nor do we), so I thought I'd see if OSHUG or any of it's members would be interested in doing so. Last year we basically had a large room in the venue with a number of projects exhibiting, running workshops and so on throughout the two days. If anyone would be interested in organising something similar as part of OggCamp, please get in touch and we can discuss further!

OSHUG camp workshop ShrimpingIt
by Mark.itto 02 Aug '13

02 Aug '13

I'm curious about this one? what is the ShrimpingIt going to do here exactly? track a face and move the cam? are you going to use any sensor for this? or the cam feed that i'd imagine goes to a more powerful device do some image processing and then this is going to talk back to the uC ( MicroController ;P ) with some move camera this way or the other? Thanks and regards. PD. Friday drinks? whats going on? haven't seen any emails about this? plans?

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!
by Andy Bennett 23 Jul '13

23 Jul '13

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!

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.
