Shiftbrite_2.0 [macetech documentation] Introduction A ShiftBrite 2.0 has an RGB LED and a small controller chip, the Allegro A6281. The A6281 provides 10-bit PWM and 7-bit current control for each of the red, green, and blue LEDs. It uses a simple clocked serial interface to receive a 10-bit brightness value for each color, resulting in over a billion possible colors. Each input is buffered and output on the other side of the module.

This allows each ShiftBrite to repeat the signal to the next, allowing longer cable runs between elements without excessive loading of microcontroller I/O pins. ShiftBrite elements feature current control and automatic overtemperature control (an overheating channel driver will shut off until it has cooled). Features Power Connections The V+ and GND pins power both the LED and the control chip. As is true of most digital electronics, if you connect power backwards or short contacts with metal objects or other modules on the chain, you WILL destroy the logic chip. Data In / Data Out Command Format. Heatsink, Enclosure, Cooler. Temperature Of course I tested the setup on a prototyping breadboard before soldering everything together and made some tests.

I wanted to know if the chip can take full white light on all 15 channels for a longer time. So I illuminated my room with 5 LED strips fully on for a few minutes and measured the temperature with my IR-thermometer and with one of my best tools, my hands. It was a little bit hot but didn't get any hotter after one minute or so. Heatsink I decided to add a heatsink to the unit. Enclosure Because all of the devices are sensitive I put all of them into an enclosure and fixed them with hot glue. Cooler Instead of the heatsink I wanted to add something else because inside of the closed plastic casing everything would get even hotter.

DIY projection screen. Building your own DIY projector. Building the projector These are the basic plans for a simple projector.The box is is made of wood with all inside surfaces painted flat black to cut down on reflection. Its important that everything is lined up on center. Also making everything adjustable fore and aft will save you some headaches if it doesn't come out right the first time. It is especially necessary that the triplet lens at the front is able to be adjusted for and aft. The box needs to be ventilated.

There are a few other things you may want to look into. In summery This is just a short introduction to DIY projectors.There is a lot of information not included here that you can find for yourself. These projectors perform very well with a high quality image and are quite sturdy. Remember to be careful. Update 2014: wow this Hubpage is really popular still after 6 years. I ran that projector 24/7 for 4 1/2 years. So my DIY projector is still functional, but its has become obsolete. Still a great project though. Goo Systems Global-Paint a High Definition Home Theater Screen. Filters & Glasses. Filters & Glasses The polarizing filters on each of the projectors are necessary to delineate left/right eye vision. The goal is to view each of the images projected by the two projectors with a different eye, which is then interpreted as depth in your brain.

For our system, we used linear polarization (as opposed to circular). The glasses are polarized at inverted 45 degree angles. At first, we purchased plastic polarizers which we cut to size and super glued to the fittings that were provided to us by the Geowall consortium. After the plastic filters failed, we purchased two Hoya 72mm linear polarizing filters (designed to reduce glare for professional photography). The Hoya filter and the mounting device separated The Hoya filter snapped into place Once in place, the lens itself can rotate without moving the focus-fixture, making calibration much easier. Calibrating the filters to the glasses For our system, the top projector is the left eye.

DIY Arduino Ambilight using ShiftBrites. This is my DIY Ambilight for my home theater PC. In this tutorial I plan to give detailed instructions on how to build a multichannel Arduino-based Ambilight for about $40 plus the Arduino which can be reused for other projects. The bill of materials include 6+ ShiftBrites (your call, I wouldn't do less than 6 though), a printed circuit board, wire, and headers.

Additionally this will require all of the components needed to get over 0.5 Amps at 5.5-9V DC on to the board to drive the ShiftBrites; this cannot be reasonably done over USB power. My ultimate goal here is to give others some ideas on how to go about this project for less money than it would cost to essentially buy everything in a kit. I went in to this trying to be resourceful and I feel pretty good about how it turned out. The first challenge was to construct my own ShiftBrite Shield.

It may be important to point out here that the ground from the ShiftBrite Shield is connected to the ground of the Arduino. Quick $10. My Arduino AtmoLight/Ambilight Clone Project. I was researching a project online the other day when I came across a project on Blogspot about how to make your own Atmolight/Ambilight television type setup using an Arduino Duemilanove , a ShiftBrite Shield and ShiftBar modules from Macetech and some 12v LED RGB lighting strips.

It was kind of amazing as I had all the parts I needed on hand to build a diy ambilight and didn’t have to order or wait for anything. The project calls for using the ShiftBar modules and RGB LED strips, but I have a hand-full of ShiftBrites and MegaBrites that I had used for another project. There is no code difference between driving the ShiftBar, ShiftBrite and MegaBrite so I didn’t have to do any major changes to the code from The AtmoLight Clone Project Site. Atmolight Components The *Brite modules are generally setup to receive the shifted data from the SPI I/O port. Modified ShiftBrite Shield I mounted the ShiftBrite modules onto the back of my primary 21″ monitor. 4 ShiftBrites 1 Megabrite RGB Module. How to build your own AtmoLight setup. The whole thing consist of a Arduino Duemilanove, one ShiftBrite Shield by macetech, a couple of Shiftbars also by macetech, a bit of cable, 12V LED RGB light strips from DealExtreme and a nice strong 12V powersource.I use the 12V line of my computers powersupply, but any 12V notebook adapter with at least 3 Amps should do the trick.

Arduino DuemilanoveShiftBrite ShieldShiftbarcable for the ShiftBars12V LED RGB light strips The first thing you need to do is to estimate how much light strips you need and order them. My setup will have 2 light strips for each side of the TV, so i need 8 light strips, 8 ShiftBars and 8 cables to connect everything.

But you could also do a setup with 2 lights on the sides and 3 lights each on the top and the bottom plus some lights for a "sum" channel.This is the nice thing about my solution, you can add as many lights as you like to your setup. You can find a ZIP file with the arduino sketch on my google code site --> arduinoatmo.zip <-- DIY Ambilight Clone Even Better Than Original Commercial Version. This DIY Ambilight–reactive ambient HDTV lighting–setup is brighter and more sophisticated than the original.

Check out the video to be blown away by the brightness. Most of the time when you’re checking out a DIY project you, at best, can say “That’s as good as the thing it’s copying”. In this case, we’d rather have the clone. Garret Mace’s Ambilight clone build might not be the simplest Ambilight clone we’ve seen but the supporting frame, adjustable modules, and sheer brightness of it (he’s got 60 watts of LEDs installed behind a 58″ Plasma HDTV) are quite impressive.

HoloPortal 3D using Kinect. Polarizing filter (photography) Circular polarizer/linear analyzer[1] filtering unpolarized light and then circularly polarizing the result. A polarizing filter or polarising filter is often placed in front of the camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or sea. Since reflections (and sky-light) tend to be at least partially linearly-polarized, a linear polarizer can be used to change the balance of the light in the photograph. The rotational orientation of the filter is adjusted for the preferred artistic effect.

For modern cameras, a circular polarizer is typically used, this comprises firstly a linear polarizer which performs the artistic function just described, followed by a quarter-wave plate which converts the now-linearly polarized light into circularly-polarised light before entering the camera. Some of the light coming from the sky is polarized (bees use this phenomenon for navigation[2]).

I am working on making an ambilight type system for my home theater. Has anyone succeeded in this? Is anybody else working on this/interested? I have found a lot of great resources that are a good start when thinking about making one: Famous "momolight" custom pc rig, has good software links: Another good looking custom setup, promises to post more soon: Anyone speak German?

PC Ambilight Company: Also, what hardware would be best for the lighting? Possible products: Some control electronic stuff: My current idea is to run a composite video (yellow) cord from the receiver (which outputs main video to projecter via hdmi) to a mini-itx or similar cheap motherboard with a video capture card. What do you guys think? DIY Ambilight Clone: Livelight. This clone of the Phillips Ambilight system allows you to enhance your video watching experience.

It is neat, compact,polished, and gets the job done. All the components fit into a attractively milled and labeled project box that allows for nine USB connectors for RGB LED light strips. The LED light strips are then adhered to the rear of the display screen. The LED strips are controlled by an ATmega32 and an FTDI chip on board.

Popular LED Projects. D.I.Y Ambilight. Simple and cheap DIY ambilight. Cut a piece of perfboard so it covers all the pin headers on the arduino, make sure the holes in the perfboard line up with the holes in the headers. It should be about 45 by 52 mm, leaving you with a grid of 17 by 20 holes. Start assembling the circuit, I have added a picture showing how I built the circuit on my piece of perfboard. All the components are on top of the board (the side without the solder rings) , the blue lines are the connections on the underside of the board. If you are using a different transistor, make sure it has the same pinout as mine (Base - Collector - Emitter) , otherwise you will need to build the circuit differently.

If you are using the same LED strip that I am using, you can cut the strip into 6 smaller segments (on the indicated lines) , you can then add some wire between each segment, which makes it easier to position them.
