Ever since I first saw the remote-controlled, motorized window blinds at IKEA, I immediately had the idea of using them to build a large screen for my video projector.
The screen should be as big as possible.
Since the IKEA roller blinds are only available in a maximum width of 140 cm, the roller blind has to be widened.
For a premium look I chose parts made of anodized aluminum.
IKEA item used:
- KADRILJ Roller blind, wireless/battery-operated grey 100×195 cm
- 2x Aluminum profile, Manufacturer: Hager, Germany – depth: 68 mm, width: 80 mm, length: 2 m
- 2x End caps, Manufacturer: Hager, Germany
- Aluminum pipe, Outside diameter: 40 mm, inner diameter: 37.4 mm, length: 3 m
- Smaller aluminum tubes, plugged together, 3 m
- Sanitary sink rubber seal, 40×33 mm
- Rigal 130inch HD Projector Screen
All aluminum parts pictured below:
1 = IKEA KADRILJ roller blind, motor and bracket | 2 = Aluminum tubes | 3 = Aluminum profiles + end covers
Hacking IKEA roller blinds to fit a large projector screen
I cut the original aluminum profile from the KADRILJ roller blind in half with the saw. We won’t be needing the original aluminum tube and the fabric.
The aluminum profiles, which serve as the new housing, are shortened to the desired total width of the screen (in my case to 3 m). Additional space for the brackets has to be included.
Photo below shows the motor drive with battery compartment.
To allow the motor to turn the long aluminum tube, I attached a suitable rubber seal with super glue.
I saw a cutout in the profile for access to the battery.
Next, I fixed the motor in the profile.

I fixed the canvas to the alu-tube with super glue.
The thinner aluminum tube serves as a counterweight and is also attached to the canvas with superglue.
The new roller blind, completely assembled …
… and mounted in the new housing.
And we are done.
Roll down for Movie time!
Here’s how it looks with the screen extended.
I made a video to show how it works with the remote control.
The screen fabric used provides excellent image quality and is comparable to a professional screen!
The screen control can of course also be integrated into an IKEA Trådfri or Philips HUE system and assigned to a control scene.
Material costs for this project: approx. US$ 300.
