For this tutorial you wil need:
Pry open the case. Best way to do it is with a screw driver on one of the sides.
Remove SMD resistors R4, R5 and R6.
Assemble BlinkStick Pro then wire it up to the main DIODER board according to the schematic. Use the supplied 3 x 330 Ohm resistors color coded orange, orange, black, black and brown to connect them to the pads on the board.
Connect BlinkStick Pro to the computer and plug the DIODER to the mains. It still needs the external power supply to drive the LEDs.
Add an Ambilight notification to the client application and link it to the BlinkStick Pro. The client application will calculate the average color on the screen and display it on the LED strips.
Once you finish the hack, the controls on the DIODER will not work any more. If you ever want to go back to all of the original features of DIODER, just remove the wires you have soldered in Step 4 and put the resistors back in.
In order to use IKEA DIODER with BlinkStick software, you have to use inverse mode.Client application
You can set the inverse mode for your client application:
This setting will be memorized for the BlinkStick with the serial number.Python Control Script
The control script that comes with Python pip package contains the mode selection option. For example:
blinkstick --set-mode 1
Mode is stored inside BlinkStick and once set is no longer required to set it unless you want to change it.Python code
BlinkStick object in Python module exposes set_mode method to enable the inverse mode.
stick = blinkstick.find_first() stick.set_mode(1) stick.set_color(name="blue") # this correctly sets color to blue
