We will make if from wooden board. Let's start!
Step 1: Tools and Materials
*Wooden board (20mm fat)
*Aku drill(or normal)
*Ruler (or geometric triangle)
*Wood borers(actually we will need only 3 and 5 mm)
Step 2: Plan and Drawing
60 3mm green LEDs.
90 3mm red LEDs.
16 5mm green LEDs.
10 5mm yellow LEDs.
5 5mm blue LEDs.
So, every 1cm we will draw a line, vertically and horizontally. We should got a net.
Step 3: Drilling
Take a aku drill, and intersected(corners) of net drill a holes. When drilled first one, check is it LED OK with a hole. If is continue with drilling. If not, look for another borer.
Step 4: Put LEDs and We Are Finish!
If hole is not enough big, take a drill a make it bigger, you don't have to put out the LEDs, borer is enough big.
And we are finish.. If you used 3mm and 5mm borers LEDs should not fall out of holes. If you wand you can put it on wall.
