Thx for this post. Anyone have a link for the electric-motor-assisted open source trail bike I heard mention of? Or was that in my dreams? A page with links like this would come in handy. Maybe there is one already?

I definitely prefer Open Source Hardware On 19 Aug 2011, at 08:58, Paul Tanner wrote: > I don't think I know what "Open Hardware" is so I'm definitely for OSH. Paul FWIW, I consider Open Source Hardware to be hardware which comes with the recipe/blueprints/source code whatever so that you can reproduce it yourself, and Open Hardware to be hardware that comes with complete specifications so that you can interface to it without any nasty surprises and without necessarily knowing what goes on inside. Open Source is better, but open is definitely a step in the right direction. Open Source hardware almost inevitably relies on open hardware: for example, you can have all the specs to a 555 timer, but you don't need to have the information necessary to build one. Or for even harder hardware, you may have the specs of a bolt (thread pitch, length, tensile strength, general resistance to corrosion etc) but you're unlikely to know the exact makeup of the alloy used to make it, or how it was tempered etc. So most simple electronic components will be open hardware. The only thing you have to be a bit careful about when talking about open source hardware is that it's more difficult to draw the boundary between source and object than it is with software. For example, I'd say an open source car is still an open source car if the complete design docs are available, even if the motors are individual proprietary units and you don't have the source for them, so long as the specification of the motors is sufficient for you to do what you want with them and they do what they are expected to do with no nasty surprises. If you take a maximalist approach, and want instructions sufficient to enable you to synthesise a car from a bunch of atoms, then you will spend most of your life sadly disappointed. It's lucky there is no one like this in the open source software (sorry, free software) world :) Best Andrew

Open (Source?) Hardware.
by Andrew Back 19 Aug '11

19 Aug '11

Hello, Some of you may also have been following the debate regarding open hardware vs. open source hardware on the Open Hardware Summit lists and/or various others. The OHS updates list archives are, for some reason, private, but Bryan Bishop has kindly been forwarding to Open Manufacturing. See: http://groups.google.com/group/openmanufacturing/msg/c9e1cd72d153a88e?hl=en& I have personally had some trouble with this debate in the past, and whilst we ended up being OSHUG and not OHUG, I don't find the argument that Open Hardware is, e.g. just a device with documented registers, entirely convincing. Inasmuch as it may have once meant this, but it has now come to be generally accepted that it is quite something else. I do agree with a lot of what Bruce Perens has to say... This is not to say that I think we should drop the "S". I've not completely made my mind up, and with regards to what we are called I don't think it matters _that_ much. Bruce does make a good case, though, and I'm definitely with him on this being a movement and the importance of it being " a lot of folks going in approximately the same direction". Which is to say that we don't all have to agree on everything. It would be a shame if this ended up being another Free Software vs. Open Source type split, though. I'm in interested as to what other folks think... Cheers, Andrew

I don't think I know what "Open Hardware" is so I'm definitely for OSH. Paul PS. Could it be a piece of hardware with the lid open?

TI Chronos eZ430.
by Andrew Back 18 Aug '11

18 Aug '11

Hello, Whilst not exactly OSHW, thought it worth pointing out that TI currently have a deal on the Chronos eZ430 wireless watch: http://tideals.com/ If you order from their eStore it works out at about £15 with shipping included. Just chatting with Ken Boak now about how easy it would be to drive one from a Nanode. Anyone on the list have experience with one? Cheers, Andrew

Not sure about OS X, but would suspect that this is unlikely using the official SDK. I also gather that it uses some proprietary IDE/compiler and that unless you pay for it you at most get access to a crippled (e.g. limited to certain object code size) version. Anyway, there should be details on the TI site somewhere... There is a community effort to develop an open source SDK which uses a compiler without such restrictions, but I'd imagine that it might not be as fully featured. Looks as though there is currently no solution to drive one with an RFM12B module via FSK, but have seen mention of the possibility of using OOK (ASK). Cheers, Andrew

Not OSHW but IoT nevertheless. Is that price for the whole dev kit or just the watch? Anyone know if software can be developed and loaded from a Mac OS/X - the links say PC?
