InTheMail | Voltlog #476

Gear up, electronics enthusiasts! In this installment of InTheMail, we’re diving deep into a treasure trove of tech goodies that are sure to elevate your workshop game. From cutting-edge ESP32-C3 development boards to sleek braided heat shrink tubing, we’ve got you covered. First up, we’re exploring the world of the ESP32-C3, a powerful microcontroller based on the RISC-V architecture.

We’ve got not one, but three dev boards to showcase, each with its unique features and form factors. Whether you need a compact solution or a board packed with extras like USB-C ports and status LEDs, we’ve got you covered. But that’s not all! We’re also taking a closer look at braided heat shrink cable sleeving, a professional-grade solution for your wiring projects.

While it comes with a few caveats, like a higher price tag and stiffer finish, the braided look is undeniably sleek and polished. Continuing our exploration, we stumble upon a rather intriguing (and slightly concerning) product – a pet positioning GPS locator with a built-in microphone. While its tracking capabilities are questionable, the ability to listen in on conversations raises some ethical concerns.

We’ll leave it up to you to decide how to utilize this technology responsibly. Moving on to more practical solutions, we’ve got our hands on a nifty hand wave sensor and a touch sensor designed for furniture integration. These clever devices allow you to control lighting and other low-voltage DC applications with a simple wave or touch, adding a touch of convenience and modernity to your projects.

And speaking of lighting, we’re diving into the world of LED tape controllers, specifically one powered by an ESP8266 module. While it may not be the ideal choice for driving analog LED tapes due to potential flickering issues, it’s a fantastic option for digital LED tapes, offering seamless integration with popular open-source firmware platforms like Tasmota, WLED, and ESPHome.

But wait, there’s more! We’re also exploring a budget-friendly Apple Watch charger clone and a unique stainless steel scrub cleaner for those who value a sparkling workshop (and cast iron pans!).

Underfloor Heating Valve Actuator Board revD | Voltlog #466

In this captivating video, Voltlog unveils the latest iteration of their revolutionary ESP32-based Valve Actuator project – Revision D. Designed to streamline manufacturing and offer improved functionality, this enhanced version is a testament to the project’s ongoing evolution. Originally conceived as an open-source solution for controlling underfloor heating systems, the Valve Actuator project has gained a loyal following due to its compatibility with popular platforms like Tasmota, ESPHome, and Home Assistant.

With over a couple of hundred units already in operation, the RevD promises to further elevate the user experience and simplify assembly. One of the most notable updates in this revision is the ability to power the valves with a separate AC voltage, such as 24V AC. This feature caters to users with pre-existing underfloor heating systems, providing greater flexibility and compatibility.

Additionally, Voltlog has optimized the PCB design by transitioning from through-hole components to surface-mount technology (SMT) wherever possible, improving manufacturability and reducing potential errors during assembly. The RevD also introduces an innovative LED control feature, allowing users to turn the output status LEDs on or off via GPIO16.

This not only conserves power but also enhances the device’s versatility, making it suitable for discreet installations where visible LEDs are undesirable. Voltlog’s commitment to quality is evident in their collaboration with PCBWay.com, the official provider of printed circuit boards for the channel.

The limited-edition first batch of RevD boards boasts a stunning red solder mask with gold-plated ENIG finish, showcasing exceptional craftsmanship and attention to detail.
