Owners of the AC Infinity AirTap T4/T6 with a Gen2 vent can replace the factory control board with our ESP32 module to add local smart home control through ESPHome and Home Assistant. The Gen2 housing keeps the original button bracket in place. The kit includes a small display cover bracket made for the Gen2 layout. This guide walks through what is in the kit, how that cover bracket fits, and the exact steps to install the PCB. [Read More]

The SiloCityLabs ESP32 Module for the AC Infinity AirTap T4/T6 already gives Home Assistant users a clean way to upgrade an AirTap vent into a connected smart-home device. The current ESPHome firmware path supports the important hardware pieces: PWM fan control, onboard temperature sensing, OLED display output, physical buttons, panel lockout, and newer IR receiver support on supported builds.

But there is another smart-home audience that could benefit from this hardware: Apple Home users.

If you’re in the Apple ecosystem, using HomePod, Siri on iPhone, Apple TV, scenes, automations, and the Apple Home app, the natural question is: Could the AirTap ESP32 upgrade kit run native Apple Home firmware instead of ESPHome?

Yes it can! HomeSpan provides developers with libraries to create an ESP32 firmware that pairs the AirTap directly with Apple Home over Wi-Fi. That’s native Apple support without Home Assistant, without a Home Assistant HomeKit Bridge, and without a separate server translating ESPHome entities into HomeKit accessories.

This post is not a finished firmware release. It is a technical roadmap for developers, makers, and advanced AirTap owners who want to understand what it would take to build one. It’s enough architecture to start the project, enough code structure to see the direction, and enough caution to avoid the obvious traps.

Owners of the AC Infinity AirTap T4/T6 may be looking for a way to retrofit their older Gen2 ESP32 module so it can operate inside the newer Gen3 AirTap vent. The Gen3 design uses a different mounting layout and sensor position, which means the original Gen2 hardware does not fit or function without modification. To solve this, we created a simple upgrade path that lets you reuse your Gen2 module with full Gen3 compatibility. [Read More]

The ESP32MiniSD is a compact add-on board designed for Seeed Studio’s XIAO ESP32-C3, XIAO ESP32-C6 or XIAO ESP32-S3, enabling microSD card storage, battery monitoring, and USB charging capabilities. In this tutorial, we’ll guide you through setting up and using the ESP32MiniSD with an ESP32 XIAO module to read and write files to a microSD card.

Unlike Adafruit’s Xiao ESP32, the ESP32MiniSD is designed to get the most out of the ESP32’s capabilities, with a focus on storage and power management. The board features a microSD card slot connecting SD card to ESP32, battery monitoring, and charging circuitry, making it ideal for ESP32 SD card integrations including data logging, file storage, and portable IoT devices. Let’s dive into the setup and usage of the ESP32MiniSD with the XIAO ESP32 module!

The “paywalling” of scientific research papers is an ongoing problem that hinders learning, hinders scientific research, and leaches profit from publicly-funded research. PaperPanda is a Chrome extension to download academic papers. Its intention is to find free links for published papers.

However what PaperPanda does under-the-hood tells another story. I’ve unearthed malicious code in PaperPanda’s Chrome extension and attempts to hide said malicious activity. This extension tried to modify my Amazon pages for unknown reasons - possibly a phisher or credit-card stealer. If you have this extension UNINSTALL IT. In this post I’ll explain how this extension is malicious and how it hides that behavior.
