Summary
Universal IR remotes able to learn codes from existing devices were once popular consumer items as well as DIY projects, but they could become quite complex themselves, sometimes with a dizzying number of buttons. [Nicolas Ruiz Neiman]’s IRis project carries the concept further with features that leverage modern parts and tools to deliver a more focused end result.
IRis keeps things clean and simple with four directional buttons, a single OK key, and a small OLED screen. IRis can learn and save IR codes and is compatible with the 
.ir
file format, meaning it can read from an absolutely massive collection of codesintended for the
Flipper Zero.
There’s also a “Be Gone” feature that mass-sends a power signal for every device in a category, re-implementing the functionality of the classic TV-B-Gone.
Hardware consists of an ESP32-WROOM-32 board, the aforementioned OLED, an IR receiver module, IR emitters, some switches, and a power supply integrating an 18650 lithium-ion cell and charger. One thing that’s pretty interesting is the detailed test suite, which runs simulated hardware via key presses on every screen to ensure the UI is working right. The enclosure also includes the CAD files in STEP format, which means modifications are a breeze.
I “ris” there were more buttons 🤣
I would think a “back” button, a dedicated power button and a volume button (or wheel) would add a lot of service for not a lot of real estate.
I agree, and I’d also add a button to cycle sequentially through a pre-configured list of a few favorite devices, so I don’t have to navigate through menus just to change power or volume on a different device in the same room. And make the whole thing much more ergonomic. Bring on the feature creep…
Nice project, terrible ergonomics.
The TiVo remote had fantastic ergonomics.
Be gone will turn on everything that’s off!
There’s a doggamn switch on the side. This has to be an ill-timed April Fool’s joke.
