Um Marco na Fotografia, digo eu, Fotos que refletem a Luz como os Originais, dependendo da origem da luz QUE INCIDE NA FOTO!

 

Reflectance paper displays photographs in a new light

By Brian Dodson

Recently the public has become aware of the potential of light field photography through the introduction of the Lytro camera. Light field recording allows an enormous degree of post-processing, letting you create just the image you want to print and display. A print, however, expresses only one aspect, no matter how carefully chosen, of the recorded light field. Can light field information be somehow encoded into a print, so an object can be examined from this side and that, or with different lighting conditions? A team of researchers at the University of California at Santa Cruz, Hewlett-Packard Laboratories, and 3M have made the first steps toward a positive answer by developing reflectance paper.

ALL WOODEN WIND GENERATOR


This page is all about a rather silly, quick project where in about 1 day I built a small wind generator using the following items, and nothing else....
(1) Wood
(2) Copper wire
(3) Surplus Neodymium magnets
(4) Dirt
(5) 10" piece of 3/8" steel shaft
(6) Two bolts, but these are optional.
...and that's all, unless we count glue, and linseed oil which I used for finishing. Initially the project started out to simply be an alternator experiment. Once I had the armature finished and a couple of the coils wound on the stator, I realized it was definitely going to be a successful one, so I decided to build it into a small wind generator. Mostly simple tools were used, although a band saw, wood lathe, and drill press came in pretty handy.

Raspberry Pi joystick

After getting MAME going on my Raspberry Pi so that I could play old arcade games. I wanted to hook up a proper joystick. Back in the 80′s I had the excellent and ubiquitous Competition Pro 5000. As mine (foolishly) got sold with my Amiga stuff I got one on eBay, and it came in the original box:

MIT develops new "reverse air conditioner" solar power system for the developing world

By David Szondy

 Solar power would appear to be an obvious choice for the developing world, but as impoverished regions need systems that are simple, self-operating and cheap to build and maintain, this is generally not the case. The ability to provide heating in addition to electricity would also be beneficial because many communities need hot water has much as they need lights. An MIT team has developed a solution that meets these needs with a solar power system that is an air conditioner built backwards.
Mention of the developing world brings up images of deserts, jungles, veldts and other hot climates, but some poor regions lie in the temperate zone. In southern Africa, for example, it can get very cold in the winter time. MIT graduate Matthew Orosz noticed this while working for the Peace Corps in Lesotho where local clinics needed not only electricity, but access to hot water. “We’ve had nurses tell us they avoid washing their hands in the winter, because the water is so cold,” he said. “So hot water is very welcome.”







E que tal poderem-se manter os Micro-Satélites em serviço por tempo indefinido?

Microthruster ion drive gives tiny satellites a boost

By David Szondy

Small-scale satellites show a lot promise, but unless they have equally small-scale thrusters they’re pretty limited in what they can do. Unfortunately conventional thrusters are heavy and take up a lot of valuable space, but a penny-sized rocket engine developed at MIT holds the prospect of not only increasing the capabilities of miniature satellites, but of combating space junk as well.

Meet Digispark, Arduino's little brother

By Adam Williams

The open-source Arduino micro-controller is a very useful piece of kit which has been implemented by hackers to power countless endeavors from Musical Umbrellas to Angry Birds Slingshot Controllers. For some projects however, the flexibility of the Arduino can be overkill and it's this issue which prompted Digispark to create a simpler, cheaper alternative - a tiny Arduino-compatible developmental circuit board that costs as little as US$12.
