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.
Update alert! The new ShiftBrite V2.0 is a redesigned and improved verson of the original ShiftBrite.
Cheap DIY Projector screen for under $30 This is a 16:9 ratio projector screen 100" Perfict for a basement game room,home Theater,computer monitor,(ect). This Project will run you $30 - $40 depending if the blackout cloth is on sale.
I decided to recycle some lightweight PVC I made a banner stand with a few years ago I didn't need anymore.
The light source for you projector will come from a 400 watt medal halide bulb and a ballast to power it. There are many different types of bulbs. What is important is its color spectrum.
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.
Size: 50mm x 50mm Optical type: transmissive polarizer Transmittance: single(38%) ; parallel(30.1%) ; crossed(0.0045%) Color: neutral gray Polarizing efficiency: 99.985% Absorption axis: 50mm Polarizer wavelength: 400~700nm Thickness: 0.18mm Direction: linear polarizer Durability: 60ºC / 90%RH (relative humidity) / 750Hours polarizer test passed Adhesive glue: No Protective film: both sides ( please remove the protective films before using polarizer. ) Application: polarizer 3D glasses, polarized sunglasses, polarized fishing glasses, polarizing microscope, polarizing camera filter, telescope filters, polarimeter, photography polarizer, light polarizer, polariscope, rotating filter with using two polarizers, photoelastic stress analysis, glare reduction, motion illusion. <p style="text-align:right;color:#A8A8A8"></p>
Polarizing Filters -Linear 3in x3in for multi-projector 3D systems 45 deg. x135 deg. For twin or multi-projector systems, these 3in square (approx. 76mm x 76mm) polarizing filters can be attached any manner you wish.
These very high-quality and high-performance polarizers are used by manufacturers in the production of LCD monitors and TVs.
TechScreen 150 is an acrylic rear projection screen surface formulated for single projector installations where projector power is limited. TechScreen 150 is suitable for viewing environments with ambient light issues. TechScreen 150 excellent for use in 3D applications and preserves polarized stereoscopic images, via a high open/closed ratio.
This is my DIY Ambilight for my home theater PC.
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.
This DIY Ambilight–reactive ambient HDTV lighting–setup is brighter and more sophisticated than the original.
Circular polarizer /linear analyzer [ 1 ] filtering unpolarized light and then circularly polarizing the result.
