Super large motorized video projector screen for less

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

Other materials:

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:

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.

A beautiful design idea for the IVAR cabinet with doors

A wall of IVAR cabinets with doors engraved is astonishingly captivating. Because IVAR is real solid wood (unlike a lot of flat-pack cupboards), it makes a great blank canvas for CNC machining work and engraving. IKEA items used: IKEA IVAR cabinets in 30mm (12″) and 50mm (20″) depths. IVAR cabinet | IKEA.com Other materials and tools: CNC Router How to engrave the IVAR cabinet with doors: Build a wall of IVAR cabinets to your preference. It’s not too difficult to shorten some in order to fill a wall exactly. I shortened the top row to 695mm and reduced the depth of the middle column to 40mm to create a 50/40/30 sequence so that I didn’t block the window but maximised storage capacity. Take a drawing, trace it in Inkscape or Adobe Illustrator into a black-only flat design. You can simplify the path at this point to reduce the time needed to engrave.
