Almost everyone can learn, but not everyone can excell.

I've been in Mexico 8 1/2 years, and I can tell you that my wife has had a very hard time learning Spanish.

I on the otherhand, hand built an electic guitar and cannot play it at all.

I am convinced that some brains are just wired to accomplish different things.

I code, but I don't code as well as I used to.

I did the survey.

Time and Unforeseen occurrence befall all of us. My wife and I have found it necessary to move back to the United States to care for our aging parents. It's been a great 8 1/2 year gig here in Mexico! So, in October, we will be relocating to Green Valley, Arizona.... Midway between Tucson Arizona USA, and Nogales Sonora Mexico.
 
Green Valley has a really neat Recreational Department that runs a wood shop, metal shop, a lapidary, etc....  So, who knows.... maybe in lieu of getting high school age kids in Mexico turned on to Arduino..... I'll be turning retired old dudes in Arizona on to Arduino!

Check on the 'Displays' Forum. You will find lots of information about the Mirroring problem of those 7" displays (800X480res)..

The Atlas stuff is good.
4  Development / Suggestions for the Arduino Project / Re: Does Arduino have a future? on: July 23, 2014, 07:53:19 pm
Kowalski's work with Cosa is a really interesting development for a C++ OO Framework. It's a bare metal approach that will give us some task scheduling that might allow us to do some things that we expect an RTOS to accomplish. He's not included any of the ARM core MCUs. If he expanded it to Cortex-M3.. for DUE.. .Then we'd want him to expand it to Cortex-M0 for ZERO.... then there would be others of us who'd like to see it expanded to Cortex-M4 for TI Tiva C series.

Then there's the IDE. Not very powerful... but hides allot of the ugliness. The Wiring based IDE forked and used by Arduino (for Arduino AVR and Cortex M0 and M3) and Texas Instruments (Energia for TI Tiva C Series) . So although there is fun stuff happening with Visual Studio and Xcode Addins, the Arduino team hiding all of the ugliness with the tool chains and so forth makes a compelling case for just putting up with the weak IDE. It's still very easy to use.

There's the hardware itself.  I wish that they could have made use of the native Ethernet and SDIO/MMC capabilities of the ATSAM3X8E and installed a physical RJ45 and microSD slot on the DUE. Instead, DUE ended up being a faster MEGA with lots of library issues to work out. They will give us all of that with the TRE, but all appearances are at increased complexity and costs. Perhaps the Arduino ZERO should have come first....   Maybe we will get a Quattro based on the Cortex-M4 and give us the missing pieces from DUE and Tiva C Series (looking at you SDIO interface... really wanted that included in the TI Launchpad!).

I like the idea of having built in microSD support, Ethernet and getting eeprom back.... but I don't want to have to school myself on Linux to get it.

Whether or not Arduino survives.. I'm not sure... none of us are privy to their financial performance. But they certainly have benefited the Maker crowd and Academia by getting the cost of basic prototyping platforms down to levels we can all afford to use! I think they've gotten the attention of bigger folks (Texas Instruments). Increased competition drives innovation and costs.

Maybe the Italians have a little work to convince us that ZERO, UNO, DUE and TRE are a real complimentary family of products....  instead of radical departures at each turn.  We've got CortexM3 with DUE.... then TRE is announced and grabs TI's Sitari (aka BeagelBone) architecture and drags along AVR with it... then we move on to ZERO and we are back in the Atmel fold with the CortexM0....  I've given Arduino lots of cash by purchasing official boards/shields and I've supported 3rd party development through clones/shields/others. But ultimately, for me, it's about a working, well supported product. We know UNO and MEGA are great.... everything else they are developing/doing feels like such a departure that we don't hesitate to look at other architectures, other vendors products. As a user community, we have no idea where Arduino is going.... 

But maybe that's not that important.  Perhaps the Arduino folks aren't either? Looks like TI and Atmel are the big suppliers for Academia and the Maker set now (is it my imagination that PIC is losing out to these guys?). TI even promotes the BeagleBone boards on it's site and makes no bone (pun intended) about the Tiva C series taking advantage of the Arduino and Wiring Frameworks, despite both of them being competitors to their own development boards. Maybe we will see a convergence of technologies, architectures and methodologies... Consider we've got AVR (Atmel 168, 328) Cortex-M3 (Atmel AM3X), Cortex-M0 (Atmel SAMD21), Cortex-M4 (Ti TM4C), Cortex A8 (Ti Sitari) architectures all running on a form of the Wiring Framework with forks of the same IDE developed in Processing.  Maybe Arduino IDE 2.0 will really extend the reach? The only questions might be do you want a board that uses Shields, Capes or BoosterPacks? Our skills may just easily transfer across platforms/vendors/products.

Wow, this got long fast.

I just received my Tiva C-Series TM4C1294XL evaluation board from Texas Instruments. It's the Connected Launchpad version.
See how it goes.

I've just received a Tiva C-Series TM4C1294XL evaluation board from Texas Instruments.. $20 usd.. (I wish the evaluation board included the microSD interface for a few more dollars, but oh well...)
I will see if it is better suited for some of the more challenging personal projects I'm working on where I had originally intended to use DUE.

However, for some really simple projects with commercial application that I'm developing.. 8 bit Arduino UNO gave me the skills and confidence to move to Tiny84a for the release project. Even Tiny84a is more powerful than I need, but I'm sure I would not have stumbled upon this little guy, if it weren't for diving into Arduino and the DUE 18 months ago.

I use a simpler solution; a 40 pin ZIF socket, upper end for AttinyX5 and lower end for AttinyX4. See http://cosa-arduino.blogspot.se/2013/04/programming-attinyx5.html
NB. The blog shows the early design with only AttinyX5. Since then I have added support for AttinyX4.

Cheers!

My goodness your work is impressive! I have a project that will use an ATTiny84A SSUR format. Never the less, I'm still grateful for the suggestions you gave above.

Paul,

correct. everything you wrote is correct.

however, for me I'm not seeing the token issues and I am able to participate on the forums.

my response was in no way an attaboy to the maintainers of the site..... they've done nothing to address the issue.

my response was simply a 'work around' for other users experiencing this problem.  IT was HORRIBLE in INPrivate Mode....  It's useable now.

Folks,

With Internet Explorer 11 running in Standard Mode (No InPrivate, No Compatability Settings, etc...) I get absolutely no Token?s8sf0aj issues with the Arduino Forum... I do have cookies for the Arduino.cc site enabled... don't know if that makes a difference.

For me... It's FIXED... it WORKS...

I'm running WIn7 64bit.... IE 11 64bit...  Hopefully this information is useful to the Website Admin/Developers and Users alike.

ajaydarez,

any progress on your project?

I was thinking if you only needed to drop 5 or 6 Kongs... it might be easier to handle the fact they the Kongs are lopsided, if you take out that u section that joins the top and bottom levels (of that can dispenser I linked to).

12  Using Arduino / Project Guidance / Feasibilty of Using SOIC components for Small Run of Prototypes (ATTiny84A-SSUR) on: June 09, 2014, 05:36:23 pm
Folks,
I want to use the ATTiny84A chip in a run of about 100 prototypes (field/endurance testing).
I will have a very basic PCB board designed... roughly 1.5" X 2".
Connections for 5 3mm LEDs on the pcb... and a 5v DC Plug Jack @ 5.5mm and an RJ45 90deg Header.
Will use vertical spacers for the 5 3mm LEDs to get the correct height for the enclosure... So they will be through hole soldered. The DC Plug Jack and the RJ45 Header will be through hole soldered as well.

However, for the ATTiny84, I'm considering using the SSUR, SOIC (small outline package)..
Obviously, I will need to be able to install this chip on solder pads that will be placed on the PCB.

Is this going to be too difficult? What tools will I need? Are fine tip soldering gun, magnifying glass and tweezers sufficient?
Never done any type of drag soldering before or worked with such tight pitches.

I think this design will be a keeper... so I hestitate to use DIP Packaging (PDIP) with it's higher costs. (double factoring in the socket)

Gives you an idea..

I generally use InPrivate setting for browsing. Every application/site I have ever used functions properly with InPrivate.... except Netflix.... So I load Netflix differently (short cut on my desktop that does not launch Netflix in InPrivate mode).

Tried doing the same with Arduino.cc... It works. I received the token thing only once.... but many times I don't receive it all.

I'm running IE11 on Win7sp1. Hope this information helps.

I've been very critical of this bug on the Arduino site for sometime.  the F12 trick sometimes would take four or 5 times in a row.....  But it all seems to behave better without InPrivate mode.

14  Using Arduino / Project Guidance / Re: Sensors & controllers project advice on: June 02, 2014, 04:04:22 pm
inmotion,
I have similar requirements for a project I'm working on.
water quality analysis. a side benefit of this work, is that it allows me to indulge myself and build an aquarium controller.

I went with a series of instruments and embedded solutions from Atlas-Scientific. I know there are cheaper alternatives, but I liked so much of what they were doing. Intelligent instruments that I communicate with serially (TTL). Atlas scientific now produces some nice carrier boards for mounting all of their embedded circuits on the sensor connectors (BNC).

I bit the bullet and spent a little bit on an enclosure that for now... stores all of the stuff so that I don't misplace it.. but in the end should result in a nice finished product (hiding all of the ugliness behind it's folding lid.) I think you can see the aforementioned carrier board in the foto... 4 holes drilled in the enclosure will hold it all in place...

Was just a small advantage of going with stuff from one vendor for me.

Regarding the code... because you are using the Arduino (not Due), you might want to consider the COSA framework that is being discussed on the forums for it's basic task scheduler...

15  Using Arduino / Project Guidance / Re: Another Orbit Yard Watering valve question. on: May 29, 2014, 10:00:03 pm
there is a nominal water pressure required so that the valve 'throws'.....

many, many moons ago I tried using these types of valves to drain a tank.... a very shallow tank... hence no head pressure and the valve would not throw.

however, for a water supply situation... that's different.
