This is my "Light Emitting Diode Persistence of Vision Helmet". I made it for my Gizmology class this semester.
On the end of the black arm is a vertical row of 8 red LEDs that are attached to a chip which controls the rate at which they flash. You can program short text messages into the chip via 3 buttons on it's side. When the LED POV flasher is on I then flip a switch on the helmut to engage the motor which spins the LEDs around my head. When in the dark the flashing LEDs combined with the rotational movement give the illusion of red letters floating around my head in a halo-like fashion.
I can't capture the red letters with a still or video camera so you will have to see it in person.
I will have a step-by-step DIY tutorial posted on The Ominous Moo so you can make one yourself!

Animated design of a 2' x 2' high density LED grow setup. Using Snowryder to compensate for the decreased light penetration of the LED's. Snowryder grows to a height of 12 - 14 inches giving a good yield of 15 - 25 gr per plant. In this 4 square foot area there are 16 plants...do the math! I show the use of 1, 2, and 4 LED panels. Due to the fact that the LED's can be 2 - 6" from the plants and the directional properties of LED's, I prefer the 4 panel configuration as it will tend to give less problems with shadows and compensate better for the short comings of LED's.

MaxM has four 8-bit analog inputs, usable in BlinkM light scripts or as an I2C input device. Here Inputs #0,#1,#2 are hooked up to three potentiometer knobs which control the amount of Red, Green, and Blue. An Arduino is also talking to the MaxM over I2C, uploading new light scripts and reading the inputs too.
The MaxM is being powered by Arduino, which in turn is being powered by a laptop.
15 second exposure with a wide open aperture. i used a bike light and a small keychain for most of these shots.
Communities at the heart of prevention: Locally led solutions to crime
London’s Living Room at City Hall
On the 20th January 2010, London Action Trust launched a series of exciting new projects, all of which work to reduce crime in the capital, tackle anti-social behaviour, and help London communities support their young people.
Superintendent Powell was presenting on Met-Track.

this nice chain will be the light array for my 2nd, bigger "wordclock". :-)
More buyers are now choosing LED walls, particularly the very popular LED walls. Their picture quality rivals the best that plasma TVs can offer, at a more efficient level of energy consumption. A LED display wall is also superior to the standard LCD TV in terms of overall picture quality.
What gives a LED TV an edge is, of course, the more sophisticated LED technology. “LED” refers to light emitting diodes, which provide illumination to the display and produce the picture. LEDs are better than the cold cathode fluorescent lights found in standard LCD TVs, in that they deliver better, more vivid images.
In addition, some LEDs have a feature called “local dimming.” This means that when a picture in a scene requires it, some LEDs are turned off completely. As a result, some parts of the screen are in total darkness while others continue to be lit. This produces very dramatic, deep blacks. An LCD TV is simply incapable of this, because the fluorescent light tubes are always on, and so the blacks in a picture are never completely black.
There are two ways that the LEDs may be laid out at the back of a 42″ LED. In “full-array” configuration, the LEDs are laid out behind the entire display. In the “edge-lit” configuration, the LEDs are placed only on the sides or edges of the panel. But still, even if only edge-lit, the lighting can reach all parts of the display including the middle, using what are called “light guides”.
Thus, some 42″ TVs may be full-array with or without local dimming, while others may be edge-lit, again with or without local dimming. The most common in the market are those that are edge-lit without local dimming, which are also the thinnest models. The ones that perform best are the full-array with local dimming type, the original type of LED wall that came out.
Buying a TV has become a lot more complicated than it was years ago. There are so many things to consider, starting with what kind of TV to get. Should one go for LCD or plasma? LED or OLED? And what size is best? Which brand stands out from the rest?
The latest TV technology is the OLED, or Organic Light Emitting Diode. OLED TVs are the thinnest and offer the best picture quality, but they are the most expensive as well. Their life span is also not as long as that of other TVs, hence an OLED TV is not a very practical choice unless you don’t mind throwing away a hefty sum of money for something that’s excellent but won’t last very long.
Next are the LED display, less pricey but a cut above standard LCD TVs. LED stands for Light Emitting Diode, referring to the light used to illuminate the screen and produce a picture. Standard LCD TVs use fluorescent tubes, which give limited color saturation with no deep blacks.
With 42-inch LED display wall, you get very clear and crisp pictures, with wide color variety and superb contrast. Compared to their LCD and plasma counterparts, they are also more energy efficient.
All things considered, 42-inch led walls are the best choice. They provide excellent picture quality at reasonable prices. True, they are usually more expensive than LCD TVs, but the enhanced picture quality is worth the extra dollars.
Many brands offer their own models of 42-inch led display walls. SBC will be the best choice.
