Story

Why spend more on expensive smart blinds when you can create your own for a fraction of the cost and tailor them to your specific needs?

After extensively researching various smart blinds, I realized that none of them met my needs. I wanted both privacy and natural light, but with traditional blinds, it’s usually one or the other. So, I decided to design my own blinds that rise from the bottom. This way, I can raise them to head height for privacy while still allowing plenty of light in from above. Here’s a draft of my design:

I gathered the necessary materials from my local hardware store and began planning. The main components are centered around an 8mm threaded rod and 3D printed parts. You can find links to all the components and 3D models above.

Here’s an illustration of the finished assembly

The electronics are relatively straightforward. The system is based on an ESP32 running ESPHome and controls a worm gear motor through an L298N motor driver. There’s also a limit switch at the top to indicate the default position. The blind’s descent is timed, so it needs to be calibrated accordingly. Here’s an illustration of the electronics assembly:

Here’s the completed build. I know it looks exposed and unfinished, but that’s intentional. I appreciate the aesthetic of transparent electronics!

I’ve integrated it with my Home Assistant, which allows me to set the blinds to a specific percentage of openness.
