DIY TiX Clock

Step 2 The Display

The display is made up of a sandwich of the display Board, The square reflector, a diffuser and a smoked perspex window.  You can place a sheet of tinfoil under the LED's to give more reflection, just make sure you cut a hole in tinfoil around a legs of each LED so it doesn't short things out.  I also sanded the lens of each led to distribute the light more.

The first three photos show the strip board version, the remainder the etched PCB version.

How big/where can you get reflector? I think this would be awesome to make a big LED sign :)

Hi there, yes it would make a good base for a LED sign, you can get bigger spaced ones too. Just google eggcrate reflector. This is one supplier, but they sell in bulk: http://www.goodmart.com/products/louvers-intl-para-image-plastic-eggcrate-2-x-4-black-styrene-lipl21-24bf.htm

Building recyclers should have them by the dozen, hey even check the huge bins when they are refurbishing a building, you might get some for free!

Theyre kinda expensive...

My (possible) attempt will be to cut card-stock in lines and wrap in foil, and make a grid... Will be able to fit more LEDS in a smaller space, and it should work the *same*

oh wait misunderstood the prices.... so this would have 1/2 by 1/2 in holes, 3/8 in high? So about 44 holes x 44 holes? I need just 24x10 :)
