Lasercut RepRap Kit

October 19, 2008 by 19 Comments

The RepRap is a self-copying 3D printer. The project has published plans for creating a lasercut acrylic version of the device. They call it a RepStrap since once assembled it could produce printed plastic versions of the machine components, bootstrapping true RepRaps. The plans are available for Ponoko an on-demand product service, and it would cost ~$380 if you used their service. The plans are free, so you could get them manufactured by other means. [vik] is still putting together the assembly instructions. He hopes to have an all inclusive electronics kit at some point too. This is another great step towards putting desktop manufacturing within reach of everyone.

SIGGRAPH 2008: The Quest For More Pixels

August 20, 2008 by 8 Comments


Long before we started reporting on [Dan Kaminsky]’s DNS chicanery, he contributed a guest post about one of our favorite sources of new technology: SIGGRAPH. The stars have aligned again and we’re happy to bring you his analysis of this year’s convention. [photo: Phong Nguyen]

So, last week, I had the pleasure of being stabbed, scanned, physically simulated, and synthetically defocused. Clearly, I must have been at SIGGRAPH 2008, the world’s biggest computer graphics conference. While it usually conflicts with Black Hat, this year I actually got to stop by, though a bit of a cold kept me from enjoying as much of it as I’d have liked. Still, I did get to walk the exhibition floor, and the papers (and videos) are all online, so I do get to write this (blissfully DNS and security unrelated) report.

Simple Tracking In 3D Space

July 23, 2008 by 19 Comments

[kylemcdonald] has posted this how to build a simple 3D tracking interface. Using 6 resisters, some wire, aluminum foil, an Arduino, and a cardboard box, he was able to do 3D capacitive sensing. Coupling that with Processing, he was able to overlay an interface using augmented reality. The video above shows a 3D tic tac toe application. While it seems less than perfect, its pretty amazing for how simple it is.

Seen anything similar to this out there? What applications would be fun with this?

Fun With Radiohead’s Data From ‘House Of Cards’

July 21, 2008 by No comments

Radiohead recently released the 3D data that was used to create the video for their song ‘House of Cards‘. [Micheal_z] sent in some of the results of his groups playtime with the data. The first effort involved some data translation. Then they created an atomizer of the head and put it up on their ungodly huge 8160×4000 pixel multi-touch display.

The video below was created by tracking the background image to orient and overlay the projection.

Radiohead Releases Laser Music Video With Data

July 14, 2008 by 8 Comments


Radiohead has released their music video for “House Of Cards.” We’ve already covered some of the tech involved. If making an entire video without cameras wasn’t edgy enough, they’ve released all the point data for people to play with and remix. The band is encouraging people to post their creations to their YouTube group.

Head over to their Google Code page to watch a making of video as well as view some of the datasets in 3D. There is a link to the entire dataset for download as well.

FABR: Another 3d Printing Project

July 13, 2008 by 7 Comments


[Lou]’s been working on his own 3d printer: fabr. We find it appealing because the entry cost is quit a bit lower than something like the reprap. 80/20 isn’t that cheap, but you don’t need a large commercial laser cutter to build the chassis. The steppers he used appear to be inexpensive ones that can be salvaged from dot matrix printer. To drive it, he’s working on a custom microstepping board and hopes to eventually develop an Arduino shield to control the stepper drivers. That’s right, it’ll get an Arudino to act as the CNC control interface.
