Here's a closeup of the mechanism that allows an old-style ball mouse to detect your hand movements. There's a light beam running between the transparent square (an LED-style light emitter) and the black square (a photocell/light detector). As you move your hand, the mouse ball moves too. It pushes against a roller that turns the spoked wheel, breaking the light beam repeatedly. Counting the number of times the beam is broken gives a precise measurement of how far your hand has moved.

From my latest delivery of stuff. The gauge is great, but the box around it has been over-tinkered, so I will strip the thing down for parts and only keep the gauge for collection purpose.
I rigged a NERF Vulcan/Havok Fire EBF-25 up so that its firing could be controlled by computer, then used the motion detecting software 'motion' for linux to have the gun fire when it detects the door opening.
The gun itself has three chained ammo belts, for a total of 74 shots, and a 12.6V lipo battery instead of the 9V D-cell battery pack it would use stock. The firing mechanism is an Arduino driving a servo connected to some pencils to pull the trigger, and there's a Logitech C300 webcam on the gun to source video. The laptop itself also plays sound files from Portal turrets when motion is detected or stops being detected. Check out www.youtube.com/watch?v=wrWUhVeEcHk for video!
Length, hight, width are related to the three photo resistors and you can deform the box by playing with light.
The color of the cube depends of the temperature that I compute from the thermistor.
This is a just a "demo" to show that it is easy with liberlab module to integrate real physical values in simulations or interactive art.

Using a series of Neodymium magnets, I cleaned up my desk, picking up the trimmed off LED legs from a project I had just soldered together. (An Adafruit LoL Shield - www.adafruit.com/products/274)
The legs stuck to the magnet, orientating themselves to match the magnetic field lines coming from the strong magnet.
Arguably the most intricate and beautiful of the collection, this piece had an immaculate layout.
It's also huge, physically, at nearly 100 in. on each side.
620-film box camera for 6x6cm exposures, made of Bakelite-ish plastic. Made in USA between 1950-61. Needs disassembling for a bit more cleaning.
Thanks Jamie!

Homebrew 175MHz prescaler for frequency counter. This was based on Heathkit IB-102 design, with some modifications. The circuit boards were my only use of a photographic technigue to develop the resist patterns. The boards came out nice but it was too time consuming for a one-off application.

Hospital Redux: When a new physician takes the hippocratic oath, she’s not likely dreaming of how she’ll set up new a new practice from the patient management systems, to the billing processes or even wait for images to get transferred from other systems. What she wants is to take care of patients! So can technology empower physicians—in private practice and even in hospitals—to make the best use of the time they have with each patient? Come find out about the most advanced technology that makes all of this as invisible as possible so that physicians focus on why they became a physician in the first place.
The Digital Health Summit, www.digitalhealthsummit.com , produced by Living in Digital Times, convenes one of the broadest spectrum audiences which makes it a can’t miss event.

Building a new components-cabinet.
Hacker (hobbyist)
In home computing, a hacker is someone who modifies software or hardware of their own private computer system. It includes building, rebuilding, modifying, and creating software (software cracking, demoscene), electronic hardware (hardware hacking, overclocking, modding), either to make it better, faster, to give it added features or to make it do something it was not originally intended to do. Hacking in this sense originated around hobbyist circles discussing the MITS Altair at the homebrew computer club.
Hacker artists[edit]
See also: Fractal art, algorithmic art and interactive art
Hacker artists create art by hacking on technology as an artistic medium. This has extended the definition of the term and what it means to be a hacker. Such artists may work with graphics, computer hardware, sculpture, music and other audio, animation, video, software, simulations, mathematics, reactive sensory systems, text, poetry, literature, or any combination thereof.
Dartmouth College musician Larry Polansky states: "Technology and art are inextricably related. Many musicians, video artists, graphic artists, and even poets who work with technology—whether designing it or using it—consider themselves to be part of the 'hacker community.' Computer artists, like non-art hackers, often find themselves on society’s fringes, developing strange, innovative uses of existing technology. There is an empathetic relationship between those, for example, who design experimental music software and hackers who write communications freeware." [3]
Another description is offered by Jenny Marketou: "Hacker artists operate as culture hackers who manipulate existing techno-semiotic structures towards a different end, to get inside cultural systems on the net and make them do things they were never intended to do." [4]
A successful software and hardware hacker artist is Mark Lottor (mkl), who has created the 3-D light art projects entitled the Cubatron, and the Big Round Cubatron. This art is made using custom computer technology, with specially designed circuit boards and programming for microprocessor chips to manipulate the LED lights.
Don Hopkins is a software hacker artist well known for his artistic cellular automata. This art, created by a cellular automata computer program, generates objects which randomly bump into each other and in turn create more objects and designs, similar to a lava lamp, except that the parts change color and form through interaction. Says Hopkins, "Cellular automata are simple rules that are applied to a grid of cells, or the pixel values of an image. The same rule is applied to every cell, to determine its next state, based on the previous state of that cell and its neighboring cells. There are many interesting cellular automata rules, and they all look very different, with amazing animated dynamic effects. 'Life' is a widely known cellular automata rule, but many other lesser known rules are much more interesting."
Some hacker artists create art by writing computer code, and others, by developing hardware. Some create with existing software tools such as Adobe Photoshop or GIMP.
The creative process of hacker artists can be more abstract than artists using non-technological media. For example, mathematicians have produced visually stunning graphic presentations of fractals, which hackers have further enhanced, often producing detailed and intricate graphics and animations from simple mathematical formulas.
