Hey, Baltimore/DC peeps! Interested in learning to program in Python?

Join +Joshua Smith and me this Saturday Dec. 12 as we take you from zero to hey-I-can-parse-and-analyze-some-data in this one-day workshop at +Digital Harbor Foundation Tech Center!

A few seats left for the workshop, tomorrow.

If you want to go, now is the time to pounce!
BlinkyTile Beta Testing Workshop

Hey Folks!

On Saturday, October 25th from 1pm to 4pm Amy Hurst and Marty McGuire will be running a beta testing workshop for the BlinkyTile at the Node.

BlinkyTile is a pentagonal tile with an RGB LED. When you solder a bunch of them together you get a programmable LED sculpture in (almost) any shape that you like.
Cost is $75 ($50 for Node members!) and gets you a BlinkyTile kit (14 tiles and a controller), USB cable, and assistance soldering it together and programming it. Costs go towards paying for the hardware and a small donation to the Node for hosting us.
More info on our EventBrite registration page if you are interested!

There's a discount code for the $50 member price. Contact me or one of the Node officers to get it.

Do you love LEDs? Sure, we all do!

Join me and +Amy Hurst on October 25th for a Blinkinlabs BlinkyTile beta testing workshop!

https://www.eventbrite.com/e/blinkytile-beta-testing-workshop-tickets-13674313239

BlinkyTile is a system of LED lights on pentagonal tiles for creating dynamic light sculptures in (almost) any shape you can imagine. Currently on its way to finishing a successful Kickstarter campaign, we’re looking for beta-testers to give us feedback on the assembly and programming of the BlinkyTile to help refine the final version that backers will receive.

In this 3 hour workshop, participants will prepare and assemble a 14-tile kit to make a dodecahedron lamp like the one seen above. Or, make a shape of your own choosing!

After soldering the boards into a sculpture, we’ll solder on the controller board and test everything out. Next, we’ll cover how to program your BlinkyTile sculpture using the Arduino programming environment.

Time permitting, we may be able to cover more advanced topics such as controlling your BlinkyTile sculpture via your computer using Processing.

No prior soldering experience is needed!

For each purchased workshop seat, we will provide:
* 14-tile kits
* BlinkyTile controller board
* 6-foot USB micro cable
* Solder and the use of a soldering station for assembly
* Stranded wire for attaching the controller board to the finished sculpture

Participants must bring:
* A laptop with the most recent Arduino (http://arduino.cc/) programming environment installed
* [Optional] A dedicated power supply (e.g. 5V phone wall adapter or a 5V USB battery pack)

Don’t forget, October 25th is the night of the Patterson Park Lantern Parade (http://www.creativealliance.org/events/2014/2014-great-halloween-lantern-parade-festival-kaleidoscope).
We think your BlinkyTile sculptures would make an amazing addition!

About this Workshop

Hosting for this workshop is graciously provided by the Baltimore Node Hackerspace. (http://baltimorenode.org/)

Workshop fees are used to cover the costs of the hardware kits. All further proceeds go to fund the Baltimore Node.

Your instructors for this workshop are Baltimore Node members Marty McGuire and Amy Hurst.

Marty McGuire is a freelance web developer in Baltimore, MD. In 2013 he created applications and content for the successful Kickstarter campaign for the BlinkyTape.

Amy Hurst is faculty at UMBC. Her research focuses on DIY and accessibility.

Game changer!!
NEW PRODUCT – PowerBoost 500 Charger – Rechargeable 5V Lipo USB Boost @ 500mA+
http://adafru.it/dzz

PowerBoost 500C is the perfect power supply for your portable project! With a built-in battery charger circuit, you'll be able to keep your project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. 

Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' for long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. 

The PowerBoost 500C has at the heart a TPS61090 boost converter from TI. This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation.

Check the product page for more info!

+Todd Blatt just posted SO MANY PICTURES of the George Crowdsourcington project build. Thanks, Todd!

The George Crowdsourcington project turned out great! Dozens of folks printed 110 parts and +Todd Blatt glued them all together.

Now George is on display at the NYC 3D Print Show Feb 13-15. Check it out if you're in the area!

Really great seeing the whole stencil + pick-n-place process.

Also liked the test rig.

Fadecandy looks awesome! I will probably grab one (okay, several) of these.

This is great. Reminds me of nickelforscale.com but IN THE BROWSER!
When creating models (replacement parts or parts that interact with real world objects), I find myself measuring a lot parameters in the 'real world'.

While calipers are still the most valuable tool for that, I simplified a lot of it by simply taking a picture of the object with a ruler in the same focal plane; then wrote a little tool that allows to draw simple lines and use that ruler to declare a known reference length - then all lines can be measured accurately enough for many uses. Also: angles between lines. Very simple, but pretty useful.

This tool is in JavaScript, so you can use it right in the browser (there is a link in the README.md)
