Build Google's Linear Book Scanner Prototype. Using a WebCam for WhiteBoarding in GoToMeeting. Have you ever wanted an easy way to communicate a simple visual idea on-the-fly from a GoToMeeting Session? GoToMeeting is awesome for communicating ideas, and with HDFaces it is awesome for getting that face-to-face feel. What I’m talking about is a quick drawing or whiteboard. So, here is what i did. I wanted to be able to use the medium I’m used to using, namely whiteboards or drawing a diagram on a pad and have that translate to a web meeting. There a quite a few tablet and drawing slate options but I wanted that direct feel of a sheet of paper or whiteboard. Here is the basic idea, use GoToMeeting HDFaces and shift focus to a webcam that is pointed downward from an overhead mount. I tool a Lagra work lamp from Ikea: and used the base and arm of the lamp.
I used an HP HD-3110 webcam. My costs for this project were: 2 lamps, $4.99, $9.99, 1 webcam $19.99, plus a few cable ties. 1. 2. iGlasses 3.

I usually would use a Canon Lide scanner to scan a few pages but this project required the capture of a few thousand pages of paper and would take forever with a normal document scanner. After looking around on the internet to see what other people have done to solve this type of problem I decided to build my own document imager.
I converted an old overhead projector into a copy stand by taking off the projector head and adapted the arm and bracket to have a 1/4 inch camera thread mount. Then I spray painted a plywood board matte black for the imager table surface. Two old desk lamps were mounted next to the table for illumination. I have been extremely happy with the results and it takes a fraction of the time a normal scanner would take to capture a few hundred pages at a time.

But that's exactly what veteran hacker Bre Pettis and his pals offer with their CupCake CNC kit: a computer-controlled 3-D printer that can whip up almost any object of less than four inches on a side from two kinds of plastic. The company's goal is to make home manufacturing cheap and common. Click to launch the photo gallery for a piece-by-piece look at building the Makerbot MakerBot's Web site says the project should take two people a weekend. It turns out that the trickiest part of making a 3-D printer kit is the software coding that tells it what to do.

DIY Continuous Ink Printer = Unlimited Free Printing. Instead of paying for absurdly priced printer cartridges, build yourself a Continuous Ink Printer (CIS) which can be made by hacking an old printer to suck ink from external reservoirs.
You can get the raw ink for dirt cheap so it’s essentially like unlimited printing for free (besides the paper). So now you can actually print your collection of pirated books! A CIS is relatively easy to create, just take an Epson Stylus 760 (a surprisingly hard to find printer) and make a few modifications to it. A tutorial walks you through the build process so you can make your own.
