Wow, I didn't think this project would be so looked at on instructables! thanks for taking a look :). I have a crappy video that I'll upload, but sadly I was an idiot and burnt out my teensy... so I'll post a video of the whole thing working later!
The following is a quick tutorial on how to build my PixelLux, an ultrabright, lo-fi, RGB LED video screen. Feel free to leave questions, comments, or suggestions! This is my first instructable, so any feedback is much appreciated.
What you will need for 1 PixelLux:
Arduino or Arduino based microcontroller (I used a Teensy++, available here)
64 Digitally addressable RGB LEDs
I suggest using a wholesaler on Alibaba, I used Schenzhen Rita Lighting LTD (Least expensive, longest wait).
Other options include Adafruit (A little more expensive) and Sparkfun (Also more expensive)
12 Volt DC, 10 Amp Power Supply (I got a 15A variable power supply from Fry's. It's AWESOME)
1/8" frosted plexiglass (available at a local glass store or acrylic store, should be a little smaller than the back)
20/22 gauge wire
Protoboard and/or pre-made PCB
32"x32"x1/8" Wood Board (for the back)
18x 32"x2.75"x1/8" Wood (for the inside and outside walls... I cut mine out of some lattice from home depot)
Tolex (to finish the light, I got mine from mojotone)
Aluminium corners (also for finishing- any hardware store has these)
4pin connector (I used a 4pin microphone cable from radioshack... but a USB should work too for smaller installations)
Cabling (the 4 pin mic cable wasn't sold anywhere so I had to make my own)
USB cable (for programming and microcontroller power)
Drill (and various bits, metal AND wood)
Nuts&Bolts(1/8" bolts should work)
Clamps (clamps everywhere)
Spray paint (I used black on the inside to make it look less wooden and more finished)
I have access to a lot of tools, which made this project much easier. If you don't have everything, don't worry... this project CAN be done with a drill, dremmel, hand saw, and clamps. you still need clamps. lots and lots of clamps. SO MANY CLAMPS.
Step 1: Building the Frame
I went to home depot and found (in the moulding and trim section) some wide lattice that I cut in half to make two 2.75" wide boards. You'll need 9x 32" boards to make the entire thing, so make sure you buy enough of the lattice.
Take your bars and create a basic frame, clamping it together and supporting the middle with an extra board or two. Place larger pieces of wood on the outside of the frame (before the clamps) to distribute the pressure. Make sure the box is square, and glue.
When it's pretty dry, add the remaining 7 bars to create the y (or x) direction of your matrix. Be sure to make them as close to the same size as possible! clamp, and glue. Let this dry for a bit.
