AjoLicht: A Cheap Party LED Matrix « hacked from pieces

I n the beginning of 2011, i was asked to create some light effect for electronic music partys. it had to be robust and simple, the budget was just 200 Euros. my first thought was obviously an LED matrix. but as i experienced in my former matrix projects, these things can be expensive. after a short brainstorming, we came up with the following concept: we decided to build single panels that contain five RGB LEDs in a row. these panels can be mounted on the ceiling and are either distributed in the room or combined to form a matrix. the design was kept very simple and therefore cheap, which allowed us to build a few panels with the budget and extend the project if more money is available.

I made a pair of light up Kanye West glasses for New Years! Firstly, I want to say that I completely ripped off this idea from my very talented friend Jordan. The electrical design is mine, but the fashion design is all hers. I highly recommend you pay her blog a visit to see what kind of other stuff she's cooked up.
The circuit on breadboard for prototyping Some time ago i uploaded a breathing LED circuit with the 555 timer chip . It became very popular and i received many comments and emails with people that made this circuit and worked fine, as well as comments with people that had troubles converting it to operate at 12 volts supply. It was designed to operate with 5 volts, because i plan to use it for a future PC mod.

From their website: Akafugu Corporation is a small electronics company that operates out of Tokyo, Japan. We specialize in fun and easy to use electronic gadgets.

Review – Akafugu TWI 7-Segment Display

Like lots of folks on the internet, I saw the DIODER and felt that it could be improved. And what better way than to make it internet-controlled? Given that I had a Nanode lying around looking for a use it seemed like providence. So the plan was this: http://alexmole.co.uk/2011/12/ikea-dioder-custom-controller/

UPDATED January 21st, 2013 I have gathered the links below to all of Mick’s fantastic work with incorporating an SD Card and LCD Display into the mix to make the wand independent of the Code Generation! Simply load BMP Images to the SD Card, select the image on the LCD display and GO! Thanks Mick for your support of the Digital Light Wand AND this blog! See the updates below. This blog page is dedicated to the Tutorial for the Digital Light Wand. http://mrossphoto.com/wordpress32/dlwblog/

Upgrading spotlights to LED « Electro Bob

http://www.electrobob.com/upgrading-spotlights-to-led/ I’ve got a couple of 12V halogen spot lights on the hallway of my apartment. I rarely turn them on because other lights usually service the area. This made me think that I could just make them dimmer and leave them on the whole night, so I’ve found a simple method to replace the bulb and mirror with a LED.

A RGB LED is nothing more than a LED that actually encases 3 small LEDs of primary colors inside. RGB LEDs can create wide range of colors by combining 3 primary colors - Red, Green, and Blue. By changing the ratio between the 3 colors, you get many in-between colors. http://www.instructables.com/id/Aurora-9x18-RGB-LED-art/

I really like the concept of ambient lighting systems which synchronize with entertainment to create a great immersive experience. And since I had a RGB led strip lying around I decided to use my Arduino and a Processing sketch to create such a system for computers which really turned out great! Here is a video of my setup and a nice demo of it working with a Star Wars video clip: Materials: If you would like to setup this system, it is quite simple and does not require any Arduino shields. The materials you will need other than an Arduino are: +RGB LED Strip (<=$15.95): You can get really cheap ones but I went with this Sparkfun LED strip due to ease of shipping ( http://www.sparkfun.com/products/10261 ). +ULN2003A (~$00.63): This chip is a transistor array for driving the LED strip which requires 12V signals with the 5V digital signals from the Arduino (order from DigiKey: http://www.digikey.com )

Arduino Based PC Ambient Lighting

This Instructable has been updated with better information and better construction, please view the 10" x 10" LED Infinity Mirror Instructable This Instructable covers building my available Full 8"x8" 32 LED Infinity Mirror Kit or re-create it with your own materials such as acrylic or hardboard sheet. It also could be scaled up or down to suit. Plans are included in the ZIP below. The Kit contains everything needed to recreate this project. Everything from high-quality glass mirrors, parts to build a durable plastic frame, 32x LEDs( color's are buyers choice), LED Controller kit, DC Jack, Wall-Wart Power Supply and wire.

8x8 LED Matrix Animations

As stated this is a 8x8 matrix so you will need 64 LEDS. I had some spare 25 LED xmas light strings, so I used these as my source for the LEDS. Timber for making the frame. This frame used approx 3.6m of 45mmx18mm of timber. Arduino Uno
A long range infrared illuminator can be made using many LEDs There are times when the small infrared LED ring built into a security camera will not cover the range or field of view you require, so you will need to find another invisible light source. Some large infrared illuminators use powerful incandescent light sources that are passed through an infrared pass filter, causing only the infrared component of the light to come through the filter. These types of infrared illuminators create intense heat due to the fact that the white light source must be fully enclosed and burn the unwanted light energy off as radiated heat.

When I saw Phil's Pet on Flickr (on the left. Click for a bigger view ) I knew I just had to learn how it was taken. Gladly for us, Trevor agreed to share the setup and production process of this wonderful light painting. It came as no surprise that this photograph is a very integrative effort. Integrative in the sense that it takes lots of techniques and puts them into one creative vision. P.S. no birds were harmed during the production.
