    I just published a custom ESPHome component for a Hynetek HUSB238A USB-PD trigger chip, which is part of the 55-mm version of the Louder-ESP32-Mini board. Originally, when I prepared a design for this board, I selected this chip to support both “dumb” mode, where it would simply request the required power profile on boot, and “smart” I2C-controlled…

As a small bonus, you can also find links to the Airplay and Snapclient web-installers, in case that is what you’re looking…

    I’m genuinely excited; I really am. Here is the new Amped Esparagus It doesn’t look that much different from the old one, apart from the TFT screen, which is hard to miss. So what’s so important? I had a mental splinter with ‘old’ Esparagus devices pretty much since I created the first one – I…

Today’s addition is an Esparagus Echo, Duo version only. I’m reviewing the Solo design at the moment, considering the idea of hosting it in the IKEA…

    A quick video about my own test setup with two Louder-ESP32-Mini boards (S-model and M-model). Speakers that were used in this build are second-hand M-Audio and no-name brands; they cost me around €10 each plus delivery. Software used in this build ESPHome configs can be found on GitHub

    Louder-ESP32-Pro has finally passed all tests and is ready for launch. Over the last few weeks, I tested the peripheral, starting with that pretty standard now (DAC, Ethernet, IR, RGB, Mic, USB-PD), and then new ones: TFT and Fan controller. As usual, I made a small mistake, it is around the TFT backlight pin, but…

    The Louder-ESP32-mini is finally available at Lectronz and Tindie. Well… kind of. It was sold out in a day, since I only had 10 boards from the first test batch, and I want to keep one for myself (for reasons explained below). One of the goals for this board was to be affordable. I think…

    I just got my hands on the new Audio Brick prototype, which is the first in the ESP32 family that has two DACs on the board. Both DACs use the same I2S bus, so they are exposed as a single device to the application, but having the second DAC has its benefits. The main motivation…
