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.

I was just up in Tucson last week. WIsh I had seen this post, I would have made the drive.

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?
54  Products / Arduino Due / Re: DUE OPC Communication on: January 15, 2014, 08:07:17 pm
I am moving in this direction myself... as well as MODBUS for PLCs... for a controller I am building.
I am downloading it for testing now. Thank you for making it available. It will be wonderful when you have it working over Ethernet or WiFi.
55  Community / Website and Forum / Arduino Forum and Windows Phone 8. Works good with specific steps. on: January 14, 2014, 11:51:44 pm
Initially I had some difficulty with the forum using Windows Phone 8's built in Internet explorer on my Nokia Lumia 920.
I could not get the Forum link on the Support tab of the menu bar to take me to the forums.

Now, I do this:
1 Goto and Login.
2 Goto the address bar and manually type
3 Enjoy trouble free forum participation without the 'token' headaches I receive on my desktop.

Hope that helps someone. The 920 has a 1280x768 resolution. In landscape mode the forums are very readable.

Perhaps you could look at the BeagleBoard Black? Completely different than  Arduino (runs Linus, uses Java for programming). However, it uses the same Ti chip (Sitara) that the TRE has adopted.
57  Development / Suggestions for the Arduino Project / Re: Updates/Comments on Library Structure Progress for Arduino IDE 1.5.X on: January 03, 2014, 03:58:48 pm
I appreciate having Access to the discussions that are occuring on the Arduino Group. Ditto for GitHub.

Eventually, just looking for a high level summary of the proposed changes to the Library Structure (rev 3+), the introduction of the "Library Manager", how this is all will aide in backwards/forward compatibality as well as Library/Hardware dependency determination. Hoping to see a "Guidelines for Writing Arduino Libraries" come out of your efforts as well.

Thanks for your hardwork.

58  Development / Suggestions for the Arduino Project / Updates/Comments on Library Structure Progress for Arduino IDE 1.5.X on: January 02, 2014, 07:20:29 pm
I've seen the dialogue on the Google Groups and Github regarding the changes to the Library Structure for Arduino IDE 1.5.X.
However, in the last 60 days there are at least 5 different threads on the Library Structure of the Arduino Development Environment in the Google Groups. I'm not even sure which is worth following. We have the Rev1 spec, recently released Rev2 spec and we know this will ultimately result in the reléase of a Rev3 spec. We're are seeing suggestions that you might even add the new library structures to the old 1.0.X IDE.

Anyway, could you folks place a nice series of Updates/Comments here for folks to read. It sure would be nice to know which direction this is going on?  Furthermore...the Library Manager... do we have to wait for Arduino IDE 2.0.X for that? Or will it follow closely behind the R3 reléase of the new (1.5 world) library structures.

59  Using Arduino / Displays / Vizic SmartGPU2 480X320 LCD w/ Audio. Uno y Due compatible. on: December 19, 2013, 02:56:18 pm
I received an email from Vizic about their newest Smart LCD.
(I have used the original 2.4" 320X240 model successfully on the UNO and found it so easy to work with).

This SmartGPU2 is interesting for a couple of different reasons:
1. 4280X320 is a decent resolution.
2. Has a  Touch Screen.
3. Has a SDCard interface that supports 32bit fat long file names (display .jpg and .bmp and play .vid and .wav)
4. Has an audio controller with a built in 3.5 Jack or you can use pins.
5. Has a configurable pwn backlight (for dimming).
6. The libraries support geometries and primitives similar to Henning LCD libraries
7 3.3v and 5v I/O compatible.
8 Uses the Arduino serial interface, simply passing commands to the onboard host controller.
9 Host controller is an Atmel ARM Cortex 3M processor (similar to DUE), that does the heavy lifting for the file system, video, audio and touch.
10 $125 USD Price.

The gotcha, straight away is the Price. But there are a few cases where this is not a bad deal. Particularly in an advanced application where one was considering seperating UI elements from Control elements.... ei... two independent Arduinos....linked together.  A cheap ColdTears LCD 3.5" is $33. A Shield is $10, A cheap audio solution is $5, a cheap Arduino Mega clone is $20. So you're up to $70 already, but it's a hodge podge of parts that you must integrate. If your building a one off or a few protypes... the extra $50 is probably not a bad deal for the integration and simplification. I love the idea of just using a few pins on one DUE and that's it.

I've written the company and asked them if they are considering adopting a 5" 800X480 panel and applying the entire feature set of their SmartGPU2 3.5" 480X3420LCD model.

Has anyone used this product?

I was hoping this idea would get more traction.

I've had so much difficulty logging into the fórums, I couldn't put up any helpful info. So frustrating.

Anyway, I've got some solar cells and lithium batteries coming. (logistics are challenging now that I live deeper in Mexico, in the mountains). Some ítems landed in my mailbox in Tucson and a visiting friend is hauling them down on Monday (a 10 hour trip - one way). I've determined that the hobby project I'm working on needs to go off the grid. That means power supply and conservation have just become big priorities.
