How to end serial port in one loop and then again start it....i hv used Serial.end();...but it ends whole serial port so is there any other way to stop serial port for a particular loop......plz reply...

Arduino driver assistance

Posted: 14 Mar 2013 03:00 AM PDT

HI, guys.

Is there a 3 amp or higher current stepper driver board for the Arduino that I can just wire or plug in?  If you know of such please give me the source and part number. I'm using Arduino 2560 mega from SainSmart.

Thank you so much.

If you go above 10K/100K then you need to take additional precautions to ensure an accurate reading (e.g. connect a capacitor in parallel with the lower resistor in the divider). 10K/100K will give a current draw of about 0.5mA, which I think is probab...

Hot Pop Factory 3D Printing Kissing Booth Highlights #3dthursday

Posted: 14 Mar 2013 03:00 AM PDT

Check out these awesome highlights from the Hot Pop Factory's 3D Printing Kissing booth, via 3ders.org:

Just like a photobooth, you can memorialize silly faces, candid moments or fabulous poses of you and your crew. But instead of a flat picture of yourself, we put together the contemporary predecessor to the photobooth where participants can get a 3-dimensional replica of their poses from all angles! Add a little Valentines spirit, and the 3D Printing Kissing Booth was born.

We set up the 3-day pop-up event at the fun and fashionable Untitled & Co storefront on Toronto's Queen Street West, and collaborated with Draft Print 3D for the 3D printing 3D scanning extravaganza! With the same equipment used for our Candy Hacking Project, we brought something that was done with our custom projects to the public for the first time. Participants got a chance to check out some 3D printers in action, get scanned for free, and choose to get their scans 3D printed as a statuette, bobble head, necklace or ring! …

I presume you mean in the demux direction. No, I haven't but I will.
It is bidirectional so it dosn't matter.

Hi, fat16lib,


Thanks a LOT for so useful contribution!
I just come across your work. May I ask you few quick questions?

1) Which Arduino libraries known NOT to work with FreeRTOS, or have timing issues?
2) Which Arduino would you recommend to handle 3...

No that is not sufficient to say it is working.

MakerBot Unveils Desktop 3D Scanner Prototype #3dthursday

Posted: 14 Mar 2013 02:00 AM PDT

SpinScan model of MakerBot Digitizer

From SXSW last week, MakerBot Unveils Desktop 3D Scanner Prototype, via MAKE:

Bre [Pettis] said in a statement. "With the MakerBot Digitizer, now everyone will be able to scan a physical item, digitize it, and print it in 3D – with little or no design experience."

The scanner is not yet ready for prime time. MakerBot is still testing the prototype. No word on the price or when makers can get their hands on one. MakerBot will start taking orders in the fall.

The scanner consists of a turntable on which you mount objects you wish to scan. Lasers and cameras translate that object into a digital files. Bre said the scanner will be ideal for archiving, prototyping, replicating, and digitizing prototypes, models, parts, artifacts, artwork, jewelry, and other objects.

"If something gets broken, you can print it again."

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don't forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you've made a cool project that combines 3D printing and electronics, be sure to let us know, and we'll feature it here!

Nick, could you write in the tutorial something about the switchable resistor. That would make clear how it works. Perhaps something like this:
