Instructables
The Black & White collection.

Designed and crafted by Maybolicious.

I wanted to make a led lap for my desktop area that you can also use for reading at night.
I have always like how Black and White compliment each other and have this distinct appeal that you can not miss.

For this project I used
*some laths(4 cm. wide, 5 mm thick) - free (left-over)
*12 white LED (3 mm.) ($2. 50)
*resistors (300 ohms), since my power supply is 8-9 volts. (5 cents)
*power jack (30 cents)
*switch (40 cents)

TOTAL COST: $3. 25

Paint:
black, white (I had some left from previous projects)

tools:
drill
drill bits
saw
mitre
sandpaper

Step 1: Materials and preparation

Find the materials you need

Then you have to prepare your material. Calculate, measure and cut the wood, then sand it with sandpaper and wipe the debris with wet mop.
Use you saw and mitre to cut the "head" of the lamp at 45 degrees.
Use your drill and drill bits to drill holes for the LEDs, power jack and the switch.
Check the images for further instructions on how to do it.

Step 2: Painting.

If you are painting outside wait until the weather is calm, if it is windy it is better to wait or you will ruin your work.

Get the paint, line up the materials and paint one layer of the paint.
It is very important to wait until the paint is completely dry before you apply the second layer(if needed)

Advice. Always use protection when painting. I recommend using gloves and mask.

Step 3: Wiring

12 LEDs wired in parallel. One 300 ohms resistors connected to the + of each LED.

Step 4: Putting the pieces together

Get all the parts, your wood glue, a triangular and start gluing the parts.
Use the triangular to glue the top of the lamp to the stem, glue at 90 degrees.

Hey, can you help me a bit. I have 20 SMD LEDs for dashboard( no need to solder ^^. They are 12v and i tested them on 7 AMP scooter battery and they were ( it was 1 diode ) working fine. I don't know how to connect them all like 15 of them. I think i don't need any resistors because i have power supply with 12v, got power jack, wires, LEDs and that's what i need right? I need sheme how to connect them all.

Did you carve a channel in either the square stock that is attached to the upright portion leading to the bulbs, or a channel in the upright lath piece?

I have explained that part in step 4 of the instructable. There is a small stock/lath that is on the back of the "upright portion" leading to the bulbs. I used a round file to carve a channel big enough to fit the wires.
what if you use, let's say, 16 or 24 leds, then what resistor you should use? is there any formula to do the math?? thanks !!

What you need is a more powerful energy/current supply. Take a look at this page http://www.theledlight.com/LED101.html. There you can find some basic information and the formula that you need. Very important thing is to pay attention to the current of your power supply http://media.wholesale-electrical-electronics.com/product/imgage/Electrical&Electronics/2010100918/44140b862d0384b42cf5f6df19fbffac.jpg look at this picture: under current it says 1000mA (or 1 ampere). Each LED consumes 0.020 Ampere (20mA) http://www.thediyworld.com/img/Typical-LED-Voltage-And-Current-Requirements.jpg , so if you want to connect 20 LED you will need curren of at least 400 mA. Good luck :)

Love this work!
Very nice!
Anyone have any suggestions as to what I would need to do to add more LEDs to make this type of lamp? I do not know anything about electricity or wiring so any help would be great.
Also, what kind of power source did you use? Where would I buy something like or one with more power if I need it for the more LEDs that I want to add?
Very Stylish.
