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.

Epilog Zing Personal Laser Etching

July 12, 2008 by 13 Comments

The new Epilog Zing is designed to bring laser engraving to the home for personal use. It’s got 25 watts of power, a small enough footprint to fit neatly on your desk, and the video above shows it has a pretty high resolution. But compared to the mini18, the Zing has less Z movement, a lower wattage, a smaller engraving area, and about half the speed. Also, with a price set around $8,000, we don’t think many people will be buying them for personal use just yet. However, if you have a small home business that requires these services, the Zing could be perfect. If you are looking for more information on laser engraving, see [ladyada’s] laser information page.

RGB Laser Diode Projector

June 9, 2008 by 19 Comments


[fl-consult] published this interesting RGB laser diode projector. The build uses three lasers, 532nm green, 660nm red and a 405nm blue diode from an XBox 360 HD-DVD drive. Aside from the salvaged diodes, it uses some off the shelf hardware to power and scan the lasers to make the display. Details are a bit lacking, but google translate helps a bit. If you’re not quite sure what’s going on: the three lasers bounce off of a set of mirrors that scan from side to side as well as up and down to create images.

M3 Headphone Amp

March 14, 2008 by 11 Comments


If you’re serious about your headphone amps, you probably already know about the M3 headphone amplifier. Instead of going for the extra tiny, they’re going the ‘screw the size, it’s all about the sound’ route. Thsi thing needs a 24v .5amp power supply. Boards are available, and the discussion has gotten so long on headwize that they exceeded the maximum thread length.

I got busy with the laser last night and came up with something new: a custom etched track pad. It still works, with a bit of added texture where I introduced it to the warm glow of the laser. Hit the link for pics and a walk through.

Ablative Power On My Doorstep

March 12, 2008 by 22 Comments


After months of waiting, emailing and waiting some more, I took the afternoon off to stay home and wait for this special delivery. (I had to wait an extra day due to a shipping issue!) I received three huge boxes in my workshop. Not only did I receive this (not so mini) Epilog mini 24, I put together a stand and unpacked a monster air filter.

Read on for the obligatory Hack-A-Day logo and my first impressions of this sweet piece of kit.
