Circuit Simulator Applet. This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. The moving yellow dots indicate current. To turn a switch on or off, just click on it. If you move the mouse over any component of the circuit, you will see a short description of that component and its current state in the lower right corner of the window. The "Circuits" menu contains a lot of sample circuits for you to try. Full Screen version. Directions. Standalone (offline) versions. Index of Circuit Examples.
Harvard cracks DNA storage, crams 700 terabytes of data into a single gram. A bioengineer and geneticist at Harvard’s Wyss Institute have successfully stored 5.5 petabits of data — around 700 terabytes — in a single gram of DNA, smashing the previous DNA data density record by a thousand times. The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0). To read the data stored in DNA, you simply sequence it — just as if you were sequencing the human genome — and convert each of the TGAC bases back into binary.
To aid with sequencing, each strand of DNA has a 19-bit address block at the start (the red bits in the image below) — so a whole vat of DNA can be sequenced out of order, and then sorted into usable data using the addresses. 3D Printed Houses Might be Closer Than You Thought. V Motion Project – Part I: The Instrument | Custom Logic Web Blog. Overview The Motion Project was a collaboration between a lot of clever creative people working together to create a machine that turns motion into music. The client for the project, Frucor (makers of V energy drink), together with their agency Colenso BBDO, kitted-out a warehouse space for this project to grow in and gathered together a group of talented people from a number of creative fields.
Producer Joel Little (Kids of 88, Goodnight Nurse) created the music, musician/tech wiz James Hayday broke the track down and wrestled it into Ableton, and Paul Sanderson of Fugitive built the tech to control the music with the help of Mike Delucchi. I also helped with the music side of the tech and built the visuals software with motion graphics warlocks Matt von Trott and Jonny Kofoed of Assembly.
The Instrument Unfortunately, this control and flexibility comes at a price… the system has a significant lag. Two Hearts Beat as One Below is my highly technical drawing of the instrument. Up next.. Artificial cells evolve proteins to structure semiconductors. A marine sponge that produces silicon dioxide fibers (credit: Hannes Grobe, AWI/Wikimedia Commons) University of California, Santa Barbara scientists have applied genetic engineering to create proteins that can be used to create electronics.
They’ve used the tools of molecular biology and principles of evolution to find proteins that can make new structures of silicon dioxide, commonly found in computer chips, and titanium dioxide, often used in solar cells. The new silica-forming protein, named silicatein X1, could even make folded sheets of silica-protein fibers. The work demonstrated that directed evolution of a mineral-producing protein could create materials with never-before seen structures. The next challenge is to learn how to change the selection pressures to evolve a specific property, such as semiconductor performance.
Directed evolution is not limited to these silica-forming proteins, as other organisms have proteins to make interesting materials too. Ref.: Lukmaan A. Training Cells to Perform Boolean Functions? It's Logical - 05/29/2012. When either FRB and FKBP or GID1 and GAI linked up, the cell’s membrane developed ruffles easily visible under a microscope. Inoue lab Johns Hopkins scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs. This feat, published in the May issue of Nature Chemical Biology, could eventually help researchers create computers that use cells as tiny circuits.
Study leader Takanari Inoue, Ph.D., an assistant professor in the Department of Cell Biology and member of the Institute of Basic Biomedical Sciences’ Center for Cell Dynamics at the Johns Hopkins University School of Medicine, explains that many researchers are striving to mimic devices in everyday use by engineering new qualities into biological materials, including biomolecules and cells. Several of those engaged in this relatively new field, known as synthetic biology, have tried to create biological computers.
ZeroN - Jinha Lee MIT Media Lab. Levitated Interaction Element - published at ACM UIST 2011. Jinha Lee and Rehmi Post Advisor: Hiroshi Ishii I think there is something fundamental behind motivations to liberate physical matter from gravity and enable control. The motivation has existed as a shared dream amongst humans for millennia. It is an idea found in mythologies, desired by alchemists, and visualized in Science Fiction movies. I have aspired to create a space where we can experience a glimpse of this future. A space where materials are free from gravitational constraints and controllable through computing technologies.ZeroN is about liberating materials from the constraints of space and time by blending the physical and digital world.
ZeroN is a new physical/digital interaction element that can be levitated and moved freely by computer in a three dimensional space. Both the computer and people can move the ZeroN simultaneously. ZeroN can remember how it has been moved. Related Project and more... Wolfram|Alpha: Computational Knowledge Engine.
