Great to see this discussion! Right now it seems the best way I have seen to approximate that content flow is through embeded content - using imger.com or similar. You can add images in sequence and with annotated steps. Perhaps some of the Farm Hack web developers might jump on this thread too?

The tool template itself has a good example about how to embed imgr and google spreadsheets etc. within the wikis - http://farmhack.net/tools/tool-template-wiki

Here is the code for embedding any content by just replacing the URL:

I quickly created an example wiki using the instructable post as an example of embedding a whole page - here http://farmhack.net/wiki/rocket-mass-heather-embed-example

but to work in forums, wikis, or tool wikis the text format (the drop down menu found bellow text edit boxes) needs to be set to "markdown syntax and HTML"

The Farm Hack web development group as been talking about creating an easier tool authoring system that would have an interface more like www.hackpad.com that would be more intuitive and remain editable (imbedded content is not as editable by all).

If this thread continues on this track - perhaps pick it up over here http://farmhack.net/forums/ability-embed-imgur-albums-tool-wikis

The tool wiki has links to the design documents - here http://farmhack.net/content/oat-dehuller-model-sr-50

I would recommend taking the design documents to a local fabrication shop to get a quote. For barley you will want the hammer design modification for sure (rather than the impact huller design which is fine for oats etc.). The second stage of winnowing the hulls and cleaning the seed is also important to consider. A clipper seed cleaner properly set up can get you most of the way there. I expect it could all be built for less than $2000. If a fabricator gets setup to do a small production run of kits, the cost could be substantially less. If you do build a version, please post your results and costs!

Hi John - did you see this related post today? http://farmhack.net/forums/20-diy-datalogger-waterproof-housing

dorn's picture

I think Louis makes a good point. I have been thinking about the same thing with the roller crimper tool and the iFARM tool. The original tool wiki posted has been lost with new approaches that confuses the post more than clarifies the progression and relationships. I think it would be great to have the concept of branching so that each of the new tools could be edited and modified on their own merit, but the evolution and heritage flows through. It is also an important part of providing credit for previous work too.

I also think that as some of these tools are used together that the concept of a meta-tools or "kits" becomes important. Some tools are a new organization of other sub-tools or components. For example, a "small scale grain production kit" is a tool that I will be developing. It is a tool that will assemble a number of other tools together in a particular combination of hardware, decision support software and spreadsheets to solve a particular economic and technical problem. Each individual tool will also have a tool wiki, or even additional sub wikis but they also have a relationship together in how the operate. Open shops enables some custom grouping of tools, but I think the ability to segment and custom organize groups of tools to address particular problems would make the content more meaningful.

This type of tagging with defined functional relationships would also enable us to group many of the tools that are attempting to solve similar problems, like data logging and automation, prone position weeding/harvesting, roller crimping, climate control etc...

I wonder if some visual navigation of tool relationships might be in the future...

Hi John,

I hope wisconsingarlicfarm responds quickly to your request. I have also sent a private e-mail along - of course it is a busy time of year for all of us! You can send private e-mails to other posters by clicking on their profile and the clicking the contact tab. Good luck! Garlic scapes just came in on our farm yesterday...

Thanks for the comment and for all your contributions. I have a huge backlog of posts waiting to get put up - both upgrades to existing tools and several new tools. I hope to get at least a few up in the next couple of weeks. It seems there is a slowdown in contributions each spring (at least from those from the temperate northern hemisphere!). We are really hoping that the upgrade to the web site this summer will make it easier to integrate other sites into Farm Hack and vise versa, and also lower barriers to using the site.

dorn's picture

Bill, There is lots going on with dialogs with GreenStart's ( www.greenstartnh.org )feed and seed initiative and building on UVM's oilseed calculator and integrating with gocrop, DNDC and others. Here is a link to a wiki I have started but sandboxed until more developed. http://farmhack.net/tools/universal-adaptive-management-software#wiki

We have an event coming up to focus on systems integration and how that fits with the unifying software concept. I have a huge backlog to post - and hope to get up on the site within the next week!

Could you share your case study and the problem you are trying to solve? I am sure is a matter of using the appropriate image analysis software tools and developing the ground truthed image/spectral libraries to calibrate the image anaysis. You may also be interested in Public Lab's open source water monitoring project
http://publiclab.org/wiki/riffle

Ecosynth is also a related open source community that could be helpful http://ecosynth.org/

Bill,
I would love to try the newest version.
What about embedding the google doc in the tool - even if it is read only. You could then add a download link with a permissions layer like tool post
http://farmhack.net/tools/open-enterprise-budget-organic-eggs

I think that might encourage use and feedback but also enable monitoring etc...

My understanding is that the screen size is very important so that after the dehulling process both the hull and the grain are able to fall or push through the screen and then are carried by the air flow up and out of the housing to the cyclone separator. There are details about the vacuum setup in the engineering drawings and notes posted. I think it was 2000cf/min and a 2hp suction fan.

My understanding is that even with the large commercial systems the process is fairly manual for re-running unhulled grains - and requires some fine tuning and attention to varying crop conditions. larger capacity seed cleaners and number of screens both prior to and after hulling will help reduce the labor of the process to get a quality finished product and reduce loss. Like with most of this kind of processing sizing and sorting for consistency helps prior to processing. That is why I think the fanning mill is so important.

dorn's picture

I will try and add more to the the wiki later - but your description is pretty accurate. The vanes in the rotor spin the seeds out where they hit the stator (stationary ring. The hull is knocked off by the impact. In some impact dehullers I have seen, the stator is a stone like material, but the one documented here used a steel ring.

The seed/grotes and hulls are blown/expelled by the air movement caused by the rotation of the fins on the side of the rotor. The cyclone separator is designed to have a vacuum on the top to separate/winnow out the hulls and have the heavier seed drop down for collection. Alternatively the mixture can be collected and run through a fanning mill (which I will be documenting later this spring). A fanning mill screens for over and under size and separates by weight.

To hull barley or spelt more velocity is needed and a higher rotational speed. Hammers/impellers are also added to the rotor and a correctly sized screen is substituted for the stationary ring such that the hulled grain can be expelled, but the unhulled grain is beat up further until it is able to exit through the screens. I do not yet have any drawings of this feature.

It will be great to have this design into autodesk inventor. I hope that the sketchup drawings are helpful as a start. It needs some cleanup but I can save it in another format like 3ds for importing if it would be useful. My hope is that we can post machine files here too if you use a torch table or water jet etc. for cutting any of the pieces.

Looks like RTK is also mentioned to add precision (http://en.wikipedia.org/wiki/Real_Time_Kinematic)
but I think there are many potential applications with lesser precision requirements - like basic record keeping, and assuring a good spread pattern or when no-tilling or tedding, or tine weeding when it is hard to see where you have been previously(some times) and a little overlap is OK, and manual correction is still possible. The precision for total automation seeding is also different then holding a heading when a manual backup and correction is possible. A fairly rough system would still enable more attention to be dedicated to cultivator or transplant adjustment etc. Fun discussion to add to the electric allis G, farmbot, and the weeder platforms etc...

I think there is some confusion with how to use the template - I edited the tool profile again with language that I hope helps. With luck the poster will try again by posting a new tool rather than editing the profile again. Any idea who is posting the Farm Bike?

dorn's picture

Great! I will add this to the tool template wiki right now. One thing to add is that in the embed code if the
width="100%" rather than a fixed pixel width- then the spreadsheet fills the available horizontal space- which can make it easier to read too.

Here are some images of approaches we use on our farm - everything from the screw in "pencil" dryer fans to drying outside or hoop structure on tarp up to 10 tons. If you have the weather and the quantity isn't that large - it is a very fast and economic way to get grain dry, and is not much labor. We have also used a small bin with a screen bottom and fan (Image is of Cayuga pure organic's dryer). I agree that it would be good to post sources for the bottom screen and fans. I have also heard of using drainage tile inside grain wagons or bins (prior to dumping grain in) used with the pencil type dryers or other fans. I have not had to try that yet, but expect I will at some point.

Here are some more photos which may help explain how it works - I like the idea of an eccentric axel - but would be great to have it function without hydraulics. That is one of the nice things about this design is that it will function even if you don't have a tractor handy.

here is a video of a similar design in action

dorn's picture

Yup - part of GreenStart's mission is to make its work open source - and we have a focus on documentation this year. I think a Farm Hack event would be a good idea - probably mid-summer. There are a number of tools coming along that would be fun to work on- including a new roller crimper inspired by the ADA bio folks that I am particularly excited about.

dorn's picture

Funny you should ask about more documentation. There is a LOT more documentation coming for this tool really soon. I have detailed process flow diagrams, parts lists with major suppliers and will be doing a video with operational instructions which I hope to complete this summer. I also have performace data and will be able to post the arduino based temperature data logs up and running again in its new fancy enclosure. I will also be building a new modular processor which I will swap out for the existing static mixer/tank. This change should drastically reduce the price of the whole unit by eliminating the need for the co-generation unit for heating the oil and running the air compressor. The new unit will be a smaller diesel direct drive air compressor and hydraulic power unit to run the air operated pumps and two metered hydraulic drive pumps for a cavitator type processor which should work at ambient temperatures. Thanks for your interest and will post more as soon as I can!

It would be great to see this system built at different scales and variations.

Which tool are you asking about? I think your post got decoupled from the tool wiki

dorn's picture

I will have to give FreeCAD a try. It may be a good option. I primarily use sketchup because it was accessible and free. I have become comfortable with it, models are easy to share, and I can export to CAD if I need to. Some of my buddies work in solidworks a lot too, but I have not tried that yet either.

I think that maybe a stand alone wiki tied to the getting started page & tool template might be a good way to start to document CAD training resources, techniques and tips etc? Other ideas?

There are still free versions of sketchup - but they are harder to find on the site because they don't promote it.

Options are Sketchup Make or 8. Here is the link

http://www.sketchup.com/download/all

dorn's picture

Great idea - for reference I attached a screen shot of what I think we are both talking about.

Anyone out there want to tackle this, or come up with a way to accomplish this in another way?

dorn's picture

For communicating and sharing design elements I have found sketchup really helpful.
We have had sketchup introductions as part of some of the events and I agree it would be good to emphasize how helpful it is to get drawings done of the project. It is nice that these can also be so easily embeded.

I started a 3d-warehouse library here with farm hack models and related components - but this could be greatly expanded and more clearly incorporated into the site too.

Funny you should mention this - I have been in touch with Alec Ellsworth who is organizing a student club already, and I think they will even have a budget. chriscallahanuvm ( http://farmhack.net/user/805) is working with Alec to get this kicked off. I will suggest that they put some info onto the UVM open shop. It sounds like it is prime time for an event on UVM campus!

dorn's picture

You bring up a great point that has been part of our design discussion from early on. I think that handling it well will be a crucial feature - as you mention there are ways to accomplish the relationships by manually linking to other tools and wikis, but it is tedious to set up. I imagine that in the shorter term we might be able to enable a menu to check and list related tool wiki's. One of the things I will be working on myself is developing groups of tools for "kits" both for various scales of grain production but also observatory "kits" for different types of environmental monitoring.

I think you might find the following document helpful - it came out of a hackathon last fall to develop a build out plan for the "open shop" concept. Part of that plan involves introducing the concept of a "problem statements" which would have relationships to tools and or wikis. That way we can relate groups of tools in a meaningful way to a single problem statement, or a single tool to relate to multiple problem statements. There is still a lot to work out as far as how to construct meaningful relationships between problem statements, but I think this is at the heart of figuring out collaborative open source development.
