772 16 Step Sequencer (With improved PCB) (+/-9V to +/-15V)
Article by Ray Wilson Back to "Music From Outer Space" Analog Synth Pages Watch Thomas White's Excellent Sequencer Videos on YouTube http://www.youtube.com/watch?v=EU6d24_eZ08 http://www.youtube.com/watch?v=AvZi-YMvHRE http://www.youtube.com/watch?v=s5cx6Z7wDOg Thomas White used the MFOS sequencer boards to produce this incredible rotary sequencer. Visit his site to keep up with his latest awesome projects. Features Improved PC board (far less kludging). Produces sequences of 4 to 16 steps in length Modes include stop at count, reverse at count, reset at count and random 16 mode Each step has coarse tune, fine tune, and switchable gate Accepts external clock and external start pulse. Simultaneous outputs with and without portamento. Forward, Back, and Reset controls ease sequence set up. Introduction Please see the pages at 16 Step Analog Sequencer Circuit for details regarding circuit descriptions etc. This page is here soley as a vehicle to present the new PC boards and support board purchases. The schematic and PCBs presented here incorporate all of the improvements and modifications shown on the previous sequencer pages. Panel to board wiring is presented here. Please browse the entire page before ordering board to ensure you understand the circuit and there is enough information provided here for you to successfully complete the project prior to purchasing PC boards. Thanks.

706 Geometry, Surfaces, Curves, Polyhedra
POV-Ray: A Tool for Creating Engaging Visualisation of Geometry Various notes on polygons and meshes Includes Surface (polygon) simplification, Clipping a polygonal facet with an arbitrary plane, Surface Relaxation and Smoothing of polygonal data, Mesh crumpling, splitting polygons, two sided facets, polygon types. Philosophy is written in this grand book - I mean universe - which stands continuously open to our gaze, but which cannot be understood unless one first learns to comprehend the language in which it is written. It is written in the language of mathematics, and its characters are triangles, circles and other geometric figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth. Galileo (1623) Distance between a point, a line and a plane The intersection of a line with another line (2D) The closest line between two lines (3D) The intersection of a line with a plane Mathematics describing a plane The intersection of two planes The intersection of three planes Polygon area and centroid calculation Inside / outside polygon test Reflection of a ray Direction Cosines Eulers number and closed surfaces Determining whether a line segment intersects a facet Coordinate transformations on the plane (2D) Cartesian, Cylindrical, and Spherical Euler angles and coordinate transformations Converting between left and right coordinate systems Clipping a line with a polygon Clockwise test for polygons in 2D Test for concave/convex polygon in 2D Area of (planar) polygons in 3D Spheres, equations and terminology The intersection of a line and a sphere (or a circle) Equation of the circle through 3 points Equation of the sphere through 4 points Intersecting area of circles on a plane Rotation of a point about an arbitrary axis Creating a plane/disk perpendicular to a line segment Intersection of two circles on the plane Circumference of an ellipse Intersection of two spheres Distributing Points on a Sphere Quadric equations in x and y of degree 2 Fowler angles: Comparing angles without trigonometry Contouring Algorithm Description of an efficient contouring algorithm as it appeared in Byte magazine. (Byte Magazine, 1987) and a more general approach for arbitrary contour planes and polygonal meshes. Spherical projections Methods for mapping points on a spherical surface onto a plane, stereographic and cylindrical (including Mercator) projections. Includes Aitoff map projection: Conversion to/from longitude/latitude (spherical map) Projection types Classification of projections from 3D to 2D and specific examples of oblique projections. A triangle was an improvement to the square wheel. It eliminated one bump. BC comics Planar (stretching) distortion in the plane Including Anamorphic projections and Mappings in the Complex Plane (Otherwise known as Conformal maps) Polygonising a scalar field Otherwise known as marching cubes and marching tetrahedrons.

474 Why Intelligent People Fail
Why Intelligent People Fail Content from Sternberg, R. (1994). In search of the human mind. New York: Harcourt Brace. 1. Lack of motivation. A talent is irrelevant if a person is not motivated to use it. Motivation may be external (for example, social approval) or internal (satisfaction from a job well-done, for instance). External sources tend to be transient, while internal sources tend to produce more consistent performance. 2. Lack of impulse control. Habitual impulsiveness gets in the way of optimal performance. Some people do not bring their full intellectual resources to bear on a problem but go with the first solution that pops into their heads. 3. Lack of perserverance and perseveration. Some people give up too easily, while others are unable to stop even when the quest will clearly be fruitless. 4. Using the wrong abilities. People may not be using the right abilities for the tasks in which they are engaged. 5. Inability to translate thought into action. Some people seem buried in thought. They have good ideas but rarely seem able to do anything about them. 6. Lack of product orientation. Some people seem more concerned about the process than the result of activity. 7. Inability to complete tasks. For some people nothing ever draws to a close. Perhaps it’s fear of what they would do next or fear of becoming hopelessly enmeshed in detail. 8. Failure to initiate. Still others are unwilling or unable to initiate a project. It may be indecision or fear of commitment. 9. Fear of failure. People may not reach peak performance because they avoid the really important challenges in life. 10. Procrastination. Some people are unable to act without pressure. They may also look for little things to do in order to put off the big ones. 11. Misattribution of blame. Some people always blame themselves for even the slightest mishap. Some always blame others. 12. Excessive self-pity. Some people spend more time feeling sorry for themselves than expending the effort necessary to overcome the problem. 13. Excessive dependency. Some people expect others to do for them what they ought to be doing themselves. 14. Wallowing in personal difficulties. Some people let their personal difficulties interfere grossly with their work. During the course of life, one can expect some real joys and some real sorrows. Maintaining a proper perspective is often difficult. 15. Distractibility and lack of concentration. Even some very intelligent people have very short attention spans. 16. Spreading oneself too think or too thick. Undertaking too many activities may result in none being completed on time. Undertaking too few can also result in missed opportunities and reduced levels of accomplishment. 17. Inability to delay gratification. Some people reward themselves and are rewarded by others for finishing small tasks, while avoiding bigger tasks that would earn them larger rewards. 18. Inability to see the forest for the trees. Some people become obsessed with details and are either unwilling or unable to see or deal with the larger picture in the projects they undertake. 19. Lack of balance between critical, analytical thinking and creative, synthetic thinking. It is important for people to learn what kind of thinking is expected of them in each situation. 20. Too little or too much self-confidence. Lack of self-confidence can gnaw away at a person’s ability to get things done and become a self-fulfilling prophecy. Conversely, individuals with too much self-confidence may not know when to admit they are wrong or in need of self-improvement.
