There is this effort by serveral Fórum members:

Connecting an Ethernet PHY to Arduino Due


47  Products / Arduino Due / Re: Arduino Due or Beaglebone Black on: February 10, 2014, 12:50:39 pm
It's interesting to note that the upcoming Arduino TRE is almost a unión of UNO and BeagleBone Black.
It will contain an UNO AVR core as well as a R3 pin layout in the interior for connecting UNO shields.
However, it also has a Texas Instruments 32-bit Sitara ARM Cortex-A8 processor with GPIO and Comm/HMI/Storage interfaces tied to it.

Likewise the Galileo from Intel contains an UNO AVR core with R3 pin layout and a second processor, the 32-bit Intel Quark (a Pentium derived SoC) driving comms and a host of other interfaces.

Makes me question the future of DUE's Cortex-3M core. I haven't heard a thing about it in a year from the Offical Keepers of Arduino... just us hobbyist/developers that have struggled with it and the Beta IDE for more than 15 months. Is Arduino staying UNO all the way, and just borrowing from others for some of the advanced comms/video/audio/storage interfaces?

I signed up to receive one of your full kits with the gripper and suction options via sponsorship of your KickStarter campaign.
Looking forward to seeing continued development.

Again, really nice work. 1st class presentation of your product/project. Would love to get our students at Espanglish Institute / Guaymas Workshop developing products of that caliber.  Wow!

Getting back to DUE. I started gathering my DUE, Taijuino and CTE stuff back as Daniel and a few other students lost interest in the GUI development for the DUE. Seems I have a total of five of these SSD1963 LCDs, shields And DUE/Taijuinos in my possession.

This would make a fine foundation for a small Boom Crane. Replace the Gripper/Suction axis with a Hook and Line. The Parallel Arms would perform the Boom/Jib functions. Replace the end with a TIp sleeve and run a line to the Base, where the Winch would be installed. Rotating Base is nice. It's far more flexible than required, but nevertheless a great starting point for a design. My intended purpose requires about 10meters of line that could lift 200grams partially extended.

You guys are modest and haven't plugged your kickstarter campaign in this thread (if you did, I missed it). But, honestly so many will be using your design and code, so it's a good idea to let other hobbyist know how they might support your efforts.  (If linking ot kickstarter campaigns is forbidden, my apologies). .

Nice work gentlemen.
51  Using Arduino / Sensors / Re: Aquarium sensors - Warning newbie question ahead of you on: February 03, 2014, 11:49:12 am
de nada.
I found the Arduino Reef Controller LInk:
A fórum search with the keywords Aquarium pH (as one phrase) yields relevant results as well. You'll find specs, code, component sources, etc.. Lots of shared experiences to draw from on these fórums.
52  Using Arduino / Sensors / Re: Aquarium sensors - Warning newbie question ahead of you on: January 31, 2014, 04:29:22 pm
I'm building one. but, before I begin, I'm  giving you GOOD links. Top notch work. Nothing I'm typing below can help you more that the work of the three links I'm citing.  (my content below is what I'm doing, or what I want to do, not how I'm doing... no schematics... the fórums are full of 'intentions', true?)

The best source for help is here: (Automated Reptile Control System) You'll find schematics and sample code too.

The best source for products is here: (Embedded Electronics for Water Quality Instruments).

There's also a guy down in Brazil: (Reef Controller) It's in Portuguese, but you should still be able to figure out what he's doing.

Ok, If you want to read a bunch of history, or about stuff I've bought and things I've proven out, you can read below...But the links above have the real meat.

My Aquarium Controller is actually a derivative of a Comprehenensive Water Quality Monitor and Transmitter that  I'm developing. The differentiator is that I'm working on OPC for integration to SCADA systems and MODBus over Serial/Ethernet for PLC integration for ALL sensors. No piecing together multiple protocols, multiple transmitters, multiple topologies, etc.. I make a living piecing together stuff and extracting data from it, but I think it might be nice to offer some of my customers a more integrated solution for some Water Quality Monitoring scenarios. It's simply monitoring and data acquisition, because in industrial/municipal settings, it's better to leverage the hardened controls already in place (my opinión). Obviously, I need some sort of interface for setup/configuration too (local lcd or website). I don't know if anyone will ever want such an all inclusive product, so I might as well make sure I can enjoy it and use it later. Hence the other two uses/derivatives below.

Residential/Consumer use I am expanding it to Monitor and Control of Aquariums. (Using I2C to expand outputs 110AC, 24VDC, PWM 0-10V, 12-24V, etc...) Here, a local interface is desireable (800X480 5" LCD) and/or Web Interface and/or Cel Phone BlueTooth interface. I'll never sell it. But someone else might want to build one like it.

A third application is Remote/Isolated Environmental Monitoring Station. This is where energy conservation, solar, gps and wireless (wifi/celular gsm) connectivity come into play. I'm excited about this one too.

Obviously the HARD stuff is all of the COMMS and Data Acquisition. Admittedly, it's all over my head and I'm quietly struggling with simple sketches for BlueTooth, GSM, Wifi and Ethernet Shields on an UNO at the moment to grasp all of that.  Then it's a matter of getting it to work with DUE.

So, when it came to Sensors and I/O. I didn't want to re-invent the Wheel. I did buy the shields from PracticalMaker. His MacroDuino stuff is interesting, but I didn't want to learn another framework. Sticking with pure C or C++ lets me easily burrow ideas from others. (I fancy myself as more of an integrator than a creator....for sure!).

So, I got in touch with Atlas-Scientific out of New York City ( Brilliant group of young guys. New Yorkers, so they cut to the chase, but are friendly. They've developed a fair number of integrated circuits (stamps) that basically serve as intelligent transmitters that communicate serially (Rs232/TTL); even producing an inexpensive MUX to really expand the network of instruments. They used them in their own solutions as they are/were doing a fair amount of environmental monitoring for the State and City of New York. Recently, they packaged these up and made them available for sale to the public. Honestly, I think I've bought 1 to 2 (sometimes 4) of everything they sell. Sure, my BOM for my initial prototype is through the roof by purchasing solutions, but that's okay.

So, I'm monitoring Temp, pH, ORP, Conductivity, Salinity, Total Dissolved Solids, Dissolved Oxygen, Color, Flow, Level, Ambient Air, Humidity, Barometric Pressure. Even trying a neat data logger. Power monitoring, power conditioning, etc.. Some of the stuff doesn't serve much of a purpose anymore. For instance the Colorometer was an idea I had for detecting petroleum traces using optics with treated lenses....given up as the science is way, way beyond my capabilities. But hey, I have a few of these sensors now, so they might as well go into my prototype. I'm also including inputs for level switches, spill switches and flow switches. Again all of this has been demoed using an UNO (some even on the DUE), but I've yet to start coding it all as one Project and stick it in one enclosure.

I've assembled everything. Just waiting on a few slick connectors and enclosure to house it. The Aquarium Controller I'm building will NEVER be commercially viable. It's simply too expensive because I rely on too many purchased components and I sense it's going to take two DUEs. It's just the culmination of other Water Quality Monitoring work I'm doing that gives me Access to the pieces/parts. You'll always be further ahead financially purchasing a commercially available product like NeptuneSys's Ápex (pretty decent stuff they are doing on the software side, with the ability to customize the control via a simple structured text command editor) or Aquadyne AquaNode (dated, they haven't substantially improved the product in a decade) . There is an Arduino based controller (angel something), but his website has buggy scripts that lock up Internet Explorer and generate warning messages from my antivirus software.

Wow, you read this far. Sorry, I warned you that there's nothing for me to show. But take a look at the Volume of information contained on the Reptile Blog.  Once I start physically building it in the new enclosure I've ordered.... I'm sure I'll get school girl gitty with excitement and start photographing and writing.

Search and EBay are your friends. Seriously, not being sarcastic. You will be surprised what is available at very reasonable cost on EBay by typing in Arduino or Arduino Sensors or Arduino GSM. Once you've identified components there... ask about them specifically here., and others are helpful.

You might try looking at what these college students did for propulsión.

True, It's a raft, but the motors look adaptable.

Honestly, you ought to try a kickstart campaign to generate sales.

That is really a good little box.

I'd recommend a few dividers inside the box, just to gather like things together....
An eggcrate like insert.... but nothing straight forward like a tic/tac/toe diagram... rather something with a few variably sized comparments.

I'd be curious to see a foto of the rear. You a bit of space behind the uno, what's that used for?
I asked, becuase I just saw a KickStarter or Indigogo campaign that featured a watch sized oscilloscope and voltmeter.
the core unit could fit in that space.... just an idea for future 'plug-in' options.
(it uses an Xmega 8bit processor its here:

I really like the idea that someone can start prototyping without unpacking very much stuff or have primary components (ie. UNO and Breadboard) loose. Rather they  can be left in place and used.

That was a very nice posts, especially for a first post.
I like your attention to asthetics. Smokey/Clear acrylic and the Stuffed Sloth are really engaging.
Thank you for sharing so many details.

There is an error where the fórum software appends a Token=?* id to the end of the URL and renders navigation imposible.
There are a series of steps one must follow to stop this behavior.  It's been observed accross many browsers and OS platforms. A real pain.

Thankfully, Windows Phone 8 appears to be least I cannot replicate the problema.

It's pretty neat how many of us are moving in this direction.  Using Arduino to supplant or augment PLCs and Industrial Controllers.

Getting whatever you build to support an OPC, CANBUS or MODBUS interface really opens it up to the world of measurement, automation and controls.

I'm  looking at a couple of MODBUS and OPC libraries for DUE now, hoping to get them working. Arduino makes for a very nice intelligent transmitter for sensors and analyzers.

Rob, have you looked at this?
