DIY 3D Gets A Nod At SIGGRAPH

Among the courses at this year’s SIGGRAPH (an annual technical conference and showcase of the latest in computer graphics research) was an introduction to 3D scanning that covers all the bases: mathematical foundations, two different build-your-own hardware approaches, and how to process and render the resulting datasets. The presenters have assembled all the course materials on a top-notch web site featuring slide shows, complete source code, and an extensive round-up with links to both commercial and homebrew 3D scanning gear. The simplest of these methods requires nothing more than a webcam, halogen light source, and a stick!

SIGGRAPH and 3D scanning have been highlighted many times on Hack a Day, but we’re swelling with pride now seeing an academic venue give a favorable nod to the DIY hacking community (on their links page). Okay, so Hack a Day isn’t called out by name, but just wait’ll next year!

HTPC Inside A Cellular Phone

Reader [Jani] always wanted to throw a PC into an old school cell phone. He based this around the extremely small Commell LS-371 motherboard which measures just 146×101 mm (~5.9×4 in). He found room behind an existing access door for a DVI connector and audio in/out. He even incorporated an OLED screen, secondary sound card for “speakerphone”, and a WiFi connector into the handset. Things start to get interesting when he decided the SSD was too large and needed to be removed from its case. The one thing that seems to be missing here is an IR receiver for a remote but since he plans on running XBMC, he may already be setup to use another option such as an iPhone to act as a remote interface.

Interactive LED Block Wall

[Dave Vondle] from IDEO Labs sent in the large LED pixel wall he built using BlinkM modules, an Arduino, and Flash to control it. The overall result is a blindingly bright, large, public display for people to interact with. The best part about the project is that [Dave Vondle] documents everything; from hardware to schematics to source code. Unfortunately, he was forced to remove the wall due to construction, but since every part of the project is open source, it lends itself to be easily recreated. I’m sure we’d all like to see a wireless controller hookup to play pong on the streets of Chicago.

Music Visualizer (oscilloscope)

The Music visualizer is actually a second build based on an earlier design[Thanks Roger]. The build was influenced by Zyra’s How to make an oscilloscope out of a television. The hack is quite simple, patch the output of an amplifier into the vertical deflection coils of the CRT. This is a good use for that old TV you may have laying around but don’t want to recycle it just yet. While on the subject we had covered the Mac SE/30 audio visualizer in 2006. For those looking for something a little more hard core, here is a bit about Homemade cathode ray tubes.

[onezerothrice] has been working hard on creating ARtisan, a flash library for bringing augmented reality to the browser. His goal in creating the library was to make AR projects quicker and easier to develop. The library can provide the location, size, and rotation of multiple markers on screen with little work from the developer. It is licensed under the GPL and comes bundled with Papervision3D, another flash library for manipulating objects in 3 dimensions. He has posted several demos with source and accompanying video.

The Pwnie Awards are an annual event at the Black Hat security conference in Las Vegas. They award the Golden Pwnie in a variety of categories: mass 0wnage, most innovative research, most overhyped bug, most epic FAIL, and our favorite: Best Song. Embedded above is [Paco Hope]’s 50 Ways to Inject Your SQL. While a strong entry, it doesn’t touch last year’s winner Kaspersky & Me: “Packin’ The K!”.

Augmented Reality Business Card

Embedded above is a neat augmented reality business card by ActionScript developer [James Alliban]. After seeing “the most impressive business card you will ever see“, he was inspired to update his own business card. His new card has a fiduciary marker on the backside and directs you to his site. A flash app on the site displays a video where he tells you more about himself. The 3D grid of planes in the video varies in depth based on the brightness of the section. He has a few more AR and tracking demos on Vimeo.

Updated: While we’re talking augmented reality, it’s worth checking out the tech behind ESPN’s baseball tracker that uses doppler radar.
