AjoLicht: A Cheap Party LED Matrix « hacked from pieces. In 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. so what’s on that board?

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. Electrical Design. Flexible 555 LED Pulsing (Breathing) Circuit. The circuit on breadboard for prototyping Some time ago i uploaded a breathing LED circuit with the 555 timer chip.

Flexible 555 LED Pulsing (Breathing) Circuit

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. Review – Akafugu TWI 7-Segment Display. Hello Readers Today we review a product from a new company based in Japan – akafugu.

I wonder that if there is any problem on it. If constant on....increase R5 (POTs are good for testing) If quick on then off forever....decrease R5 For longer fades and more control with the 10K POTs....increase C1.

I have now created a Blog Page specifically for the Digital Light Wand – LPD8806 version that is0-mick designed using an SD card reader and LCD Display Shield. This new page has a video and detailed wiring diagram for the LPD8806 version of the Digital Light Wand and also some specific information regarding the formatting and use of BMP files. The Page is located through the menu at the top of this page or via this link. Please post questions and comments regarding that version of the light wand to that page. Cheers! ——— 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! This blog page is dedicated to the Tutorial for the Digital Light Wand.

Upgrading spotlights to LED « Electro Bob. 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. RGB-LED controller. Aurora 9x18 RGB LED art. A RGB LED is nothing more than a LED that actually encases 3 small LEDs of primary colors inside.

Aurora 9x18 RGB LED art

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. RGB LEDs are often called full-color LEDs. Most of brightness controlling circuit utilizes the method called PWM. March 20, 2011.

Over the course of roughly 2 years starting May 2009 I built a 8x8x8 RGB LED cube. You can see the quick specifications in the info box to the right. You can see all the posts I made during the build of this cube if you click the below link: You can visit my blog's web album to easily see the photos all in one go: Stair LED Light - 10mm with Bezel: Project Kits - Stair Light Kit - 10mm-Stair-LED-with-Bezel - Alan's Electronic Projects Online Store. Single 10mm LED light for use with the Stair Light Controller. This unit comes ready to install. It is prepped with a 7 inch wire lead and includes two wire connectors. The black plastic light bezel provides a nice flush mount look on any surface. Note that the quarter is only shown as a size indication. When off the LED lens is clear, the plastic bezel only comes in black but is easily painted to match any decor you may have.

Installation is easy, simply drill a 9/16 inch hole in the stair at the desired location, pop this unit in and connect it to a wire running to the stair lighting controller. This light will work with any 5 volt system and draws 20mA of current. Arduino Based PC Ambient Lighting. 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 ( +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: LED Infinity Mirror, 32 LEDs, Selectable Patterns, Quality Frame. 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. With an overall dimension of 12" x 12" x 2.25" and 32x 5mm LEDs with controller. I can also put together custom kits, if you would like to supply some of your own parts or if you want some of the steps/parts built for you. 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. Build the LED ARRAY ILLUMINATOR - Page 1 of 12. 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. Because of this intense heat, incandescent filtered illuminators cannot be used indoors and may not be suitable for many outdoor installations.
