3D Printed Relief Photo
I took a stereo photo of our cat kissing our dog and made a 3D printed relief photo from the left and right images. Shapeways.com 3D printed the stereo photo model in color sandstone. See http://shpws.me/q4OW
The 3D relief photo measures 3.5 x 2 inches and .5 inch thick at the highest point on the right side (photo above).
To construct the 3D print model I used PhotoSculpt Textures 2 software. Check out http://www.photosculpt.net

LED Animated Fire Necktie Photos
Yesterday Kate modeled my LED animated fire necktie at a Fortress of the Arts meetup photo shoot for models and photographers in Philadelphia.
See http://andymodlaphotography.blogspot.com/2014/03/animated-led-fire-necktie.html for a description of the LED display.
Animated LED Fire Necktie
The Hunger Games costumes are catching fire, so how about an animated LED fire simulation necktie. With this electronic wearable you can be virtually warm in winter.
I built the display using an 8x8 color LED matrix from Adafruit.com and an Arduino Pro Mini 5V/16MHz controller from Sparkfun.com.
Gilad Dayagi (giladaya) wrote the original software and described his animation work and algorithm in the Arduino forum:
I modified his code to use the Adafruit NeoPixel 8x8 display and placed the updated code in github.com at:
The Adafruit LED matrix display, Arduino controller, and battery holder fit nicely in a 3 inch wide necktie. The parts do not add much weight to the tie when using coin cell batteries. Placing the LED matrix behind the lining in the tie helped to diffuse its light.
(1) Adafruit NeoPixel NeoMatrix 8x8 64 RGB LED Pixel Matrix (Adafruit.com)
(1) Arduino Pro Mini 328 - 5V/16MHz controller (Sparkfun.com)
(1) 2 x 2032 Coin Cell Battery Holder 6v output with on/off switch and connector JST (Adafruit.com)
(2) CR2032 Lithium Coin Cell Battery
Stranded wire ( I cut up a network CAT5 flexible cable and used the internal wires )
An alternate power source that lasts much longer is a 3 x AAA battery Holder with on/off switch and 2-pin JST. This power source weighs down the tie noticeably and is more bulky.
I soldered all the wire connections. The circuit is very simple. Here is a diagram of my layout and circuit:
Note that header pins were soldered on the Arduino controller to program it.
If you don't want to use headers you can use the sparkfun pro micro and program with a USB connection. I used the Arduino 1.0.5 SDK and installed the Neopixel library from Adafruit.com
Adafruit has very nice tutorials about Neopixel programming. Highly recommended reading for this project if you want to build one yourself.
I have an Adafruit Flora that I could have used as a controller, but I wanted a smaller board to be able to fit everything behind the 8x8 display board. If you are new to Arduino projects, I recommend the Flora.
