I love IKEA and her low cost products.

Last week I found this STRÅLA lamp.

The cost is $4.99, so I bought it.
Lighting the lamp I saw that it ‘s very pretty but also … too soft…

So I thought to modify the LED and add a RGB led.
With simple modify you can obtain a dinamic lamp.
I used an Arduino to do a fast work, but of course it isn’t necessary.
You can use a small microcontroller like a PIC12F675, or a ATTiny.

And this it the result:

How to

Before all, you have to buy a STRÅLA 

Open the package

And disassemble the original LED

As you can see the LED shape isn’t normal, but there is a cone in the center to better spread the light.
So I modify the RGB led to obtain the same effects and I also smoothed the surface.

Connect the wire to the led and reassemble all.

To connect the RGB led I used a strip wire and some pin.

And now you can connect this pin to PWM ports of Arduino.

The black, blue and white wire are the RGB pin of the LED.

The red one is the Anode.

Good modding
