For those of you aspiring LEGO builders, Technic is a sub-brand of LEGO which uses more advanced and sophisticated parts for elaborate projects: these sort of models include functional machines with working gears, pistons, springs, pumps, and special LEGO bricks that contain drilled holes for holding axles, rods, pins, and whatnot -- these hole-drilled bricks are what we'll be using to build the design portion of the lamp. In particular, we'll be using two specific types of hole bricks: a 1x2 brick with two holes in it
, and a 1x1 brick with one hole in it
. You can technically use any Technic hole brick of your choosing -- which vary in sizes and holes, but I personally recommend using these two types, as you'll have more room for making details and providing individual light components.
Also in the LEGO product line are traditional 1x1 plates -- square or round -- that are made with transparent colors. The studs of these plates will of course pop into place of the aforementioned Technic bricks, thus when arranged in a colorful mosaic pattern, you'll simply place a light bulb behind the wall of bricks/plates to create the illusion of individual illuminated colored dots -- just like an LED board, but rather like a Lite Brite set with colored pegs!
I tend to match transparent dots with coordinated Technic bricks, such as placing transparent red dots on red bricks, obviously, but again, feel free to deviate as you please. Be advised, though, that Technic hole bricks -- the specific sizes I recommend using -- are only available in limited colors, which means you have to be aware when designing your pattern, as perhaps your particular desired colors are unavailable. Some colors are available in 1x1 and 1x2 Technic hole bricks, but certain colors are rare and expensive. The same goes with transparent plates: only a handful of colors (mostly primary) are available. In the example Super Mario mood lamp I've provided here, I used the following colors for Technic bricks: tan, lime green, red, blue, white, black, light grey, dark grey, and yellow. For the transparent plates, I've chosen red, dark blue, light blue, clear (no color), neon green, dark green, and orange. I did a few techniques for substitution where necessary: for example, green Technic 1x1 hole bricks are rare and expensive, and 1x2 hole bricks are non-existent -- thus, I've chosen blue bricks, and when the transparent dark green plates were popped into place, the blue area of the brick was somewhat covered up, thus making a substitute "green" brick. You can do similar things like putting transparent orange plates in yellow Technic bricks, as there are no orange 1x1 or 1x2 Technic hole bricks available in the LEGO parts library.
