Most department stores and pharmacies still have photo labs and kiosks that let you print your photos. Just pop in an SD card or a USB drive, select the photos you want to print, and out they come, in whatever size you choose and on whatever paper you prefer. We have to wonder though: Who does that anymore?With everyone sharing photos online, whether it's via Facebook, Google+'s new photo features, or the freshly overhauled Flickr, we're not sure people still print out photos and put them in photo albums these days. Sure, there's always a place for a well-printed photo in a frame on the wall, one your desk, or as a gift. Still, photo printing kiosks and apps that promise to let you print from home and pick up at the pharmacy are easy to find. Do you use them?Photo by Infrogmation.
What to do if your keyboard on the screen. And if there are dozens of screens: At CES, the Russian design Art Lebedev, the company shows upcoming Optimus Aux Optimus popularis keyboard with a mini and a series of six unique keyboard for data input devices on the key to the home screen.

Do You Print Photos Anymore?
Most department stores and pharmacies still have photo labs and kiosks that let you print your photos. Just pop in an SD card or a USB drive, select the photos you want to print, and out they come, in whatever size you choose and on whatever paper you prefer.

3D Printed Photograph
The 3d printer in our office (an Objet Connex500) prints with a rigid, semitransparent white material that can be used to create these unique black and white photographic prints. These prints may be indecipherable when viewed from the side, but when backlit with a diffuse light, they recreate images with surprisingly high precision and even add some subtle dimensionality and texture to the scene. Some will remember Beer's law from high school chemistry; it states that the absorption of light by a material varies linearly with the distance light travels through the material. By varying the thickness of a region of this semitransparent print you can control the amount of light that is able to pass through, thereby controlling the brightness (thinner regions of material will appear brighter and thicker regions darker). In this project, I've mapped each individual greyscale pixel value of an image to thickness, allowing me to precisely reproduce any greyscale image. The photos I've printed include an adorable picture my mom took of our cat Teddy (fig 4), Saturn and its moon Titan taken by the Cassini space probe (fig 5 and 6), and a huge print (19x16") of Mt. Williamson by Ansel Adams (fig 1, 2, and 3).
All of these 3D models were generated algorithmically from Processing using the ModelBuilder library by Marius Watz. This library allows you to save 3D geometries in the STL file format, STL files that form a watertight mesh can be printed by a 3D printer. To get started using this code yourself, download the latest version of the ModelBuilder library, unzip the file, and copy the folder into Processing's "libraries" folder. If you have installed the predecessor to the ModelBuilder library (called the Unlekker library), you will need to delete it. Once this is done restart Processing.

String name = "YOUR_FILE_NAME.jpg";
with the name of your greyscale image. I believe .gif, .jpg, .tga, and .png files will all work fine, but I have only tested .jpg so far. Run the sketch, after a minute or two Processing will tell you that it is writing an STL file and eventually it will tell you that it is finished. The resulting file will be located in the sketch's folder named "NAME_OF_ORIGINAL_FILE.stl"
You can open the stl file with a variety of CAD software and stl viewers, I like MeshLab for simple viewing (it's free and open source).
By default my sketch will scale images to 8" wide, with a base thickness of 0.02" and feature thickness of up to 0.1", you can change these setting by adjusting the variable at the top of the sketch.

Chrome Plating of Car Headlights and Parts
I want to shear my experience with Electroplating parts with, Copper,Nickel, and Chrome. I will update this Instructable with more photos, and more detailed instructions later. This shows the basic for it. If there's anyone interested out there, I will help out as good as I can.
Sorry about the lack of pictures and video from the buffing and polishing. I was so focused, that i completely forgot to use the camera :)
An IMPORTANT thing, is to check out with your country's regulations regarding these chemicals. And NEVER EVER dispose them out in the nature. Some of them are harmful to the environment, and poisonous to yourself.
The gases from the plating are odorless, but extremely corrosive. I was just slightly unaware a moment, and got some nose bleeding after this. NOT recommended..! Show respect for the chemicals, and always read the datasheet before start. Use goggles and gloves.
Here you can see the old chrome of the headlamp. Its really worn out. And the door handles are in poor condition. Heavily infected with Zinc Pest. Had to clean out all the pitting with my dremel drill.How to make wooden feathers
Painted wooden feathers made of pine. You can make them any size, but these are approximately 10" x 3" x .75". I made these at TechShop San Francisco (www.techshop.ws). These are great for using up scrap wood.
Cut your wood into the approximate length of the feathers you'd like to make. I used a chop saw, but you can also use a bandsaw, table saw, jigsaw or whatever you like. Wrapped bracelet
In this instructable I'll show you how to make these wrapped bracelet. I hope you like it!
To make these bracelets, you will need the following:- suede lace (not sure about how to translate it)
- flat-nose plier
- scissors
- beads
- lace clip
Precision-cooked, fried hamburgers - Modernist cryo-fried burgers
This is my take on Modernist cryo-fried burgers as described in Modernist Cuisine. They are a perfect medium rare throughout the inside with a thin, crispy outer crust. This is achieved by cryo-frying the burgers: cooking them sous vide, briefly freezing them in liquid nitrogen to keep the inside from overcooking, and then frying them in hot oil. The burgers were juicy and tender with an extremely satisfying crunch through the browned surface. The actual work making the burgers was minimal, but the setup complicated. I cooked these as part of Fried Day at the Instructables lab when we already had both liquid nitrogen and pots of hot oil ready to go.
Here are the abbreviated instructions; go through each step for pictures and more information: Mix ground beef with salt to achieve a 0.8% salt concentration, refrigerate for an hourCook beef sous vide to an internal temperature of 131°FFreeze the outside of the burgers in liquid nitrogen for 30 secondsFry the burgers in oil at approximately 425°F for 30 secondsMany thanks to ReneediCherri for photography.
Modernist Cuisine recommends grinding your own meat to make the best burgers. They are undoubtably right, but knowing the amount of effort that goes into grinding meat from making sausage, I opted to skip this step, and instead started with 100% grass-finished ground beef.
Add salt to make a 0.8% concentration. Fold the salt into the ground beef, form patties with a mass of approximately 180 - 200 g, put them into plastic bags, and add 5 g of a neutral oil.
