[Udi] lives in an apartment with a pleasant balcony. He also has three kids who are home most of the time now, so he finds himself spending a little more time out on the balcony than he used to. To upgrade his experience, he installed a completely custom shade controller to automatically open and close his sunshade as the day progresses.
Automatic motors for blinds and other shades are available for purchase, but [Udi]’s shade is too big for any of these small motors to work. Finding a large servo with a 2:1 gear ration was the first step, as well as creating a custom mount for it to attach to the sunshade. Once the mechanical situation was solved, he programmed an ESP32 to control the servo. The ESP32 originally had control buttons wired to it, but [Udi] eventually transitioned to NFC for limit switch capabilities and also implemented voice control for the build as well.
While not the first shade controller we’ve ever seen, this build does make excellent use of appropriate hardware and its built-in features and although we suppose it’s possible this could have been done with a 555 timer, the project came together very well, especially for [Ubi]’s first Arduino-compatible build. If you decide to replicate this build, though, make sure that your shade controller is rental-friendly if it needs to be.

More than once a maker has wanted a thing, only to find it more economical to build it themselves. When your domicile has massive windows, closing what can feel like a mile of blinds becomes a trial every afternoon — or every time you sit down for a movie. [Kyle Stewart-Frantz] had enough of that and automated his blinds.
After taking down and dismantling his existing roller blinds, he rebuilt it using 1-1/4 in EMT conduit for the blinds’ roll to mount a 12V electric shade kit within — the key part: the motor is remote controlled. Fitting it inside the conduit takes a bit of hacking and smashing if you don’t want to or can’t 3D print specific parts. Reattaching the roller blind also takes a fair bit of precision lest they unroll crooked every time. He advises a quick test and fit to the window before moving on to calibrating and linking all your blinds to one remote — unless you want a different headache.
Now, to get Alexa to do your bidding.

[Lenore] added a bit of customization to her office window hangings by fitting roller curtains with custom printed fabric. The treatment seen above is a $20 Enje roller blind from Ikea but that logo is all Evil Mad Science. The weight at the bottom of the fabric uses a friction-fit plastic insert that can be stapled onto new material. Some fusible tape was ironed onto the sides to finish those edges, and the roller at the top has strong adhesive that remains for a second use after peeling off the original material.
A fabric printer was used to produce this rendition of shades. But we’d like to see some conductive thread added for a fabric-based display that can be rolled up when not in use.
