J'étais à mon magasin local du dollar l'autre jour et quand j'ai vu cette lumière en forme de coeur de contact, j'ai dû entailler un pour mon gf. Voici une entaille rapide sur la façon dont faire une lumière régulière de contact et la transformer en une lumière rougeoyante de nuit de coeur.

This one has been around but it’s too cool.

Cool LED Shirt you can make yourself!

design
1. Pick a garment to sew on, a pattern that will let you sew your own garment, or design your own pattern.

2. Design your display. decide on the number of LEDs you want and their general placement. This will depend on the garment you chose and the microcontroller you intend to use as well as how you’d like the display to look. I decided to sew a simple tank top and I chose to place the LEDs evenly across my tank top every 2″. Since my tank top is approximately 28″ around and 12″ tall I needed 84 LEDs. (Note! The pictures here show a different shirt with 140 LEDs spaced 1″ apart.)

3. Decide on the microcontroller you want to use. Choose one with an internal oscillator, and make sure you have enough i/o pins to control your matrix. It’s a good idea to pick a microcontroller you are familiar with and read the data sheet carefully! It can take some reading to discover that what you thought was a general purpose I/O pin is input only or an open drain output.

4. Decide on the power-source you want to use.

Check out this cool DIY on making your own LED Pimp Bedroom and RGB light HOWTO!

I got this idea last year from a couple different things, one was this rope lightdecoration at the Illini Union courtyard cafe that continuously changes colors. The other was from this huge bright LED sign at Irving Park and Sheridan in Chicago that is at some mechanic that uses the sign to advertise his parking spaces for Cubs games. I made this with Red, Green, and Blue LEDs, so I can make any color of the rainbow. This is done the same way your TV or computer monitor works, Red+Green=Yellow, Red+Blue=Purple. I threw in some ultraviolet LEDs in hopes they’d be nice like a black light but they’re more violet than a black light.Go to index 1 of 2 if you want to see more technical pictures.

Here’s a cool LED HOWTO guide including how to power LEDs using DC or AC.

LED lights are extremely efficient compared to standard incandescent lighting. No other lighting source outputs as many lumens per watt. They are particularly efficient at producing a single color of light. Other light sources have to produce the entire spectrum and optically filter out unwanted colors. However, LEDs can be manufactured to produce only one wavelength of light. This makes them particularly useful in stop lights.

Another advantage to LEDs is their operating temperature. Most available today can be function for hours and remain cool to the touch. Directionality is another key property. They only emit light over a relatively small angle. This can be advantageous for reading lights, but hinders performance when attempting to light an entire room.

If the advantages of LED lighting interest you, Myths Busted, LED Lighting is an excellent article by a researcher in outdoor lighting solutions. (And the source of most my information.)

Here’s a simple LED HOWTO using LEDs and some batteries for those of you interested in
LEDs and want a class-101 on it.
