Lampduino is a computer-controlled free-standing floor lamp, comprised of an 8x8 RGB LED matrix. The lamp stands 45" high and 18" wide. Light emanate...
Parts List (64) 5mm common anode RGB LED's. I bought mine on eBay (1) ITead Studio Colorduino or an Arduino with Itead Studio Colors Shield (1) large...
Each of the 64 LED's in the matrix is enclosed in a 2x2x2" cell. First, draw out your cutting lines in pencil on your foam board. You will need 14 gr...
Next, cut the grid pieces apart with your x-acto knife and straightedge.
Cut horizontal slits into the grid pieces, one in the center of each cell. Make sure the slits go through all the layers. You needn't be super preci...
Assemble the 14 grid pieces to form the core of your matrix. Don't glue it yet. You might have to take it apart several times while wiring it up. I ...
I chose wire wrap as the wiring method for this project because: it’s cheap there are no toxic fumes there is no risk of overheating and ...
When you are done with this stage, you will have 8 strands of 8 LED's each.
Thread the LED strands into the gaps between the grid pieces.
Next, flip the matrix over so that the slots running perpendicular to the strands are on top. Wiring up the rows is a bit trickier, because we're wor...
I ran all of my column wires through a single slot in the matrix ,to the bottom. I cut slots in the bottom for running the row wires. This was a mis...
Wrap the 32 wires coming out of the matrix into the two 18-pin male headers. Note that you have to wrap on the short end of each pin, because we need...
After the wiring and testing is done, you can attach the top, bottom, and sides. Note that there is an 3" long extension of the side pieces on the bo...
My intention is to wrap the matrix in wood, and attach it to a wooden stand. However, due to time constraints, I decided to first prototype it using ...
Cut two 18x18" squares of drafting film. Attach one to each side of the matrix. I made a mistake, and used hot glue. Hot glue is hard to deal with ...
An Arduino doesn't have enough I/O pins, nor enough current output to drive an 8x8 RGB LED matrix. Therefore, one needs to interface it with external ...
The Colorduino comes with the Arduino bootloader pre-loaded, so it can be programmed via the Arduino IDE. It doesn't have a built-in USB to serial co...
In my design, the Colorduino acts as a slave to a PC host application. Since a 24-bit per pixel RGB frame takes up 192 bytes, the Colorduino can't st...
The host software, RGBmtx, is a Processing sketch. It is a heavily hacked up version of mtxControl (thanks, Tobi!), and excellent visual animation ed...
In order to allow the lamp to display the widest gamut of colors, it is important to set the white balance as best as you can. Using RGBmtx in record...
If you use a FTDI-based serial port, including an Arduino Duemilanove, there is a 16ms latency introduced by the driver. This short latency normally ...
In order to synchronize our matrix with music, we need to connect it to an audio source. I want it to sync to the bass beats. Building upon the music...
The matrix took about 8 hours total to construct. The wiring took another 20 or so hours. A lot of the construction/assembly work was extremely tedio...
