The new material is comprised of photorefractive polymers. These chemicals have photoelectric properties that make them well-suited to storing the optical interference patterns used to produce holograms. When a photorefractive polymer is exposed to a pattern of bright and dark areas, electrons are released from the areas exposed to high-intensity light and migrate to areas that are darker. Once in place, the electron-rich areas diffract light differently from the electron-poor ones, allowing the original interference pattern to be reproduced when the material is exposed to light Holodeck 0.1: the durable, rewritable holographic display

Advances in display technology are simply amazing. I hope to see holographic display units so common place that they are used in cheap kids toys like and LCD would be used today.|

Quite amazing. I hope he builds some more computer parts out of wood. … a few months ago, I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to actually function as a sort of adder or counter. Once I had that idea, I knew I had to try it at some point, and recently, I finally got around to building my marble binary adding machine. [via MAKE]

Think of a smoke alarm…but more general. The photoset of the build is quite detailed and lends itself to being easily reproducible, it would be a fun project for a long weekend. [via brass goggles]

Another useful tool for getting all creative with your LEGOS. A handy tutorial showing you common ratios for the gears that are common to the LEGO Mindstorm kit. You can also find these gears in a variety of other LEGO sets. And if your totally flummoxed about what gears are just having a look around should answer some of your questions.|

If your LEGO construction skills have progressed past the point of building stuff out of the instruction booklets then you have undoubtedly had the desire to play with the versatile LEGO motors. The LEGO motors are amazingly handy, I can’t say enough good things about that really. The biggest question is what one to use? As they are a bit pricey (hey, these are LEGOs after all) picking and choosing the style might save you some valuable cash. I personally like the 8735 motors myself, but that’s because I have a few from my old Mindstorm kit. |

The bike is made from Bamboo that has been smoked and heat treated to prevent splitting. Lugs are available in carbon fiber or hemp fiber, for the all-natural look. The chainstays are available in carbon fiber for extra stiffness in the drivetrain. As Sean says they are working on the paper and epoxy versions. I’m sure he is joking but hey, he knows his Gibson! If I were in the market for a bike and I wanted something that was light weight and strong but I didn’t want full carbon fiber I’d choose bamboo hands down. The stuff is strong as hell and looks great.

This is an impressive modification of a standard PC keyboard into a work of steampunk art.|

Unmanned Attack Helicopter, Ver. 2, 2004 Oh yeah… This would liven up the company picnic don’t you think? I wonder how he managed to ignite the rocket without throwing the chopper into a nasty spin? Any one else have something like this? BB gun mounted on a glider maybe? The artist also has some very impressive sculptures listed in his online portfolio. I like the ‘Bronze Skull’ ones myself.

Woooow! This is sooooo cool! Ok, I feel better now. I was scanning Neat-o-ramma tonight and saw this. This is the best DIY flight sim I have ever seen, even has multi axis movement simulation.|

Often considered a marketing invention to help boost sales in an otherwise slow economic period for retailers, Valentine’s Day needn’t be another excuse to express love through our capalitistic, consumeristic ways. There are plenty of options to give without hitting the mall, so this year CH decided to put together a list of homemade Valentines gifts (and kits). I’m partial to the naughty ice cream sandwich myself but the sun jar would be cool to give as a gift.

Thats all well and good but they forgot to mention that they can be made of LEGO blocks. Neat! [Thanks for agent Eugene for this one]

This is something nice, German artist Thomas Raschke creates metal real world representations of things that exist in the world of computer graphics, except without texture or even surfaces. | previous posts » |
