DIY CO2 Laser Cutter For Sheet Metal | The Tinbasher Sheet Metal Blog Would you like to build a CO2 laser cutter similar to this? That can cut things like this: Instructables has an exceptional step-by-step guide as to how to go about it. As the introduction states: The general idea of this CO2 laser system is that a beam is directed down to a part for cutting. There are pictures a plenty, videos of it in action, a block diagram pdf and seven extensive pages of instructions on how to build one. Well, the site is called Instructables.
What Is the Fundamental Nature of Consciousness? [Excerpt] This chapter from PHI: A Voyage from the Brain to the Soul, by Giulio Tononi (Pantheon, 2012) describes Tononi’s theory of consciousness as a measure of information. The brain, Tononi postulates, consists of billions of neurons: think of them as if they were transistorlike bits that, when tallied, sum to equal more than their parts. That increment above and beyond—Tononi calls it phi—represents the degree to which any being, whether human or mule, remains conscious. From the forthcoming book PHI: A Voyage from the Brain to the Soul, by Giulio Tononi Copyright © 2012 by Giulio Tononi Published by arrangement with Pantheon Books, an imprint of The Knopf Doubleday Publishing Group, a division of Random House, Inc. Integrated Information: The Many and the One In which is shown that consciousness lives where information is integrated by a single entity above and beyond its parts When is an entity one entity? While musing such matters, Galileo was startled by a voice. An image came to Galileo.

The Stream of Consciousness The Stream of Consciousness (1892) William James The first and foremost concrete fact which every one will affirm to belong to his inner experience is the fact that consciousness of some sort goes on. 'States of mind' succeed each other in him. ....How does it go on? 1) Every 'state' tends to be part of a personal consciousness. 2) Within each personal consciousness states are always changing. 3) Each personal consciousness is sensibly continuous. 4) It is interested in some parts of its object to the exclusion of others, and welcomes or rejects -- chooses from among them, in a word -- all the while. In considering these four points successively, we shall have to plunge in medias res as regards our nomenclature and use psychological terms which can only be adequately defined in later chapters of the book. [Personal Nature of Consciousness] When I say every 'state' or 'thought' is part of a personal consciousness, 'personal consciousness' is one of the terms in question. a. b. [Attention]

Consciousness Representation of consciousness from the seventeenth century At one time consciousness was viewed with skepticism by many scientists, but in recent years it has become a significant topic of research in psychology, neuropsychology and neuroscience. The primary focus is on understanding what it means biologically and psychologically for information to be present in consciousness—that is, on determining the neural and psychological correlates of consciousness. The majority of experimental studies assess consciousness by asking human subjects for a verbal report of their experiences (e.g., "tell me if you notice anything when I do this"). Issues of interest include phenomena such as subliminal perception, blindsight, denial of impairment, and altered states of consciousness produced by drugs and alcohol, or spiritual or meditative techniques.

PCB CNC aus Metalab, dem offenen Zentrum für meta-disziplinäre Magier und technisch-kreative Enthusiasten. Introduction CNCs can facilitate in the creation of PCBS: Manual etching and then using CNC to drill automatically. Cutting out the board , to have round PCBs, or similar. Currently, all three steps are working on the Geilomat. For the isolation, there is the normal approach, where all contours of copper areas are milled. Some results are given in the soup of the Geilomat 0805 SMD resistors work fine, although the solder locations are not visible any more. Examples A normal isolated result. A voronoi milled PCB (left), a normally milled PCB, and a traditional PCB. Time Consumption For a complete, dense EuroPCB, expect about one hour of total time: For an arduino shield, expect about 30 minutes: Pros/Cons Pros: Quite Faster than manual UV-exposing, etching and drilling. Cons: If the board is not mounted completely flat, the isolation might be not deep enough, and hence there are short circuits.
The Highly Sensitive Person Pocket laser engraver. For the Arduino I started out writing my own software. But while searching for a good way to control movement from the serial port I stumbled upon something called "Grbl ". This is a g-code interpreter with lots of nifty functions. As I already had everything connected to the Arduino I had to ether change my connections or change the software. I have however changed the pin-out since then and here in the instructable I use the default pin-out of Grbl. Important: The current version of Grbl (0.6b) has a bug in the queue system. Any way you choose to do it you will end up with a .hex file that you must get into the Arduino. The Arduino needs to be set up for the job. Grbl 0.6b '$' to dump current settings" If you enter $ followed by return you will get a list of options. You must change the steps/mm for X and Y axis to 53.333 on both. Now you are ready for the computer setup.
Schach für 3 Leute Amazing! Three player Chess on a hexagonal board. 3 player chess played with just the same rules as standard 2 player chess but adjusted to take account of the hexagonal board. The game is not a gimmick; it's a really interesting version of Chess that enables an extra player to play. The extra rules are minimal but the hexagonal nature of the board does bend your mind: When a pieces that moves diagonally reaches the middle point of the board, it can travel in one of two directions. The first King must be actually taken rather than just checkmated. The ramifications of of the hexagonal board turn out to be pretty fascinating, once you've understood the way that pieces move through the middle point. Having a temporary ally can be more important than having a good position. The 3 player chess boards are made from a stained hardwood as are the pieces. The larger 3 player chess set has a 8.5cm (3.5 inch) King; it measures 54cm from point to point across the board. Change to: $
