This is a small ESPHome project designed to control and monitor a garage door opener using an optical encoder as a movement sensor. For example, the Precision PDS-800. Key features include: The door ...

When you’re trying to learn how an algorithm works, it’s not always easy to visualize what’s going on. Well, except for maybe binary sort, thanks to the phone book. Professor [thatguyer] is a computer ...

The Functionalist design philosophy that Dieter Rams brought to Braun from the 50s to the 90s still inspires the look of a few devices, including Apple’s iPod, Teenage Engineer’s synthesizers and ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

Note: The SI4703 requires a specific boot sequence — SDA must be pulled LOW before releasing RESET. This is handled automatically in SI4703Radio::begin(). Do not add an external pull-up on SDA before ...

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...
