New Holographic Display Technology
Posted on 02.07.08 by John @ 7:48 pm

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.

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

Wooden Binary Adding Machine
Posted on 06.22.07 by John @ 10:41 pm

 


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.

Problem Light (Steampunk edition)
Posted on 06.22.07 by John @ 5:25 am

Very nice execution of this project.

Think of a smoke alarm…but more general.
So, as I began plotting my own problem light, in the Venture Bros style, my friend told me she was redoing her living room steampunk-style.
I began to wonder, how do you do a late 1800s LED…and I ran to scribble a drawing.

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.

Amazing LEGO Motor FAQ
Posted on 05.26.07 by John @ 10:44 am

LEGO motor FAQIf 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 list give you important info like motor RPM, stall current, torque, and even efficiency. Just the stuff you need to maximize your project. I guess it goes without saying that you can use these motors for non-LEGO applications as well. Just let your creative mind go wild.

The Bamboo and Carbon Fiber Bike Frame
Posted on 04.26.07 by John @ 7:53 pm

Bamboo bike frame
I got a comment on my post about bike frames made of bamboo today and figured it was worth of a new post

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.

R/C Helecopter With Rockets!

ROV with teethOne of the captions on the page says it all:

Unmanned Attack Helicopter, Ver. 2, 2004
Gas Powered Radio Control Helicopter modified to carry and remotely fire model rockets

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.

An AVR-based Analog Plotbot with an E-Paper Display
Posted on 03.14.07 by John @ 3:56 pm

This is just perfect! Using a Magna Doodle as an output device for a computer is just brilliant.

What do you get when you mix a 1970’s style analog chart recorder, an 8-bit microcontroller, and a Fisher-Price Doodle Pro? A truly 21st century toy: An analog PlotBot with e-paper display technology!
Our machine is based around a vintage analog X-Y data recorder. Its original purpose in life was to perform basic laboratory data collection, plotting two voltages against each other, and was one of the primary tools for that purpose right up until computers took over that job in the 1980’s. Because they were once so common and are now generally obsolete, it’s quite easy to get one of your own. There are usually several under $50 on eBay at any given time, and that’s where we got ours. …
The other major modification that we’ve made is that we’ve replaced the pen and paper with what seems like out of reach technology: an inexpensive and readily available e-paper display: the panel from a Doodle Pro. …
The Doodle Pro is a descendent of the Magna Doodle, a classic children’s toy dating to 1974. (I’m not sure what makes this a "Pro"
anything, however.) It uses a simple magnetophoretic display, where ferromagnetic particles are suspended with near-neutral buoyancy in an opaque, viscous white liquid. Using a magnetic stylus, you can attract the black particles to the top surface, or with a magnetic "eraser" on the bottom side, pull the particles away, leaving only the white liquid visible.

Best DIY 747 Flight Simulator Ever
Posted on 02.06.07 by John @ 9:52 pm

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.

Australian amateur pilot and flight sim enthusiast Matthew Sheil spent 10 years and $230,000 to create a homemade flight simulator that precisely mimics the 747 cockpit down to the last dial, knob, and switch!

DIY Valentines
Posted on 02.06.07 by John @ 8:18 pm

Heart EggsOver on Cool Hunting there’s a lovely list of do it yourself Valentines Day projects.

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.

Spaceship Serenity Paper Model
Posted on 02.05.07 by John @ 5:45 am

I found this beautiful paper model of the spaceship from the science fiction TV series ‘Firefly‘. I just started watching the DVDs yesterday so I naturally was looking around the ‘Net for more info on the show. It’s pretty good, pity that it was axed so quickly by Fox, but I guess everyone says that.
The ship looks like a pretty complex build, it has more detail that you would expect, it even has the ambassadors  shuttle craft.

Maneki Neko
Posted on 02.04.07 by John @ 7:20 am

The Wikipedia say on the subject of ‘Maneke Neko’ that:
 The Maneki Neko (???, literally "Beckoning Cat"; also known as Welcoming Cat, Lucky Cat, Money cat or Fortune Cat) is a common Japanese sculpture, often made of porcelain or ceramic, which is believed to give good luck to the owner.

Thats all well and good but they forgot to mention that they can be made of LEGO blocks. Neat!
