UL-Certified TP-Link Kasa Smart Plug with Dual Outlet Sells for $19.99 (Promo)

WiFi smart sockets to control home appliances have been around for a few years, and one of my favorite companies is Sonoff as they offer a variety of affordable smart plugs pre-loaded with eWelink firmware and compatible with open-source firmware like Tasmota and ESPurna. The company is also attentive to safety. communicate issues with customers, and recently wrote a post entitled “Safety is our responsibility” where they detail all steps taken to make sure their mains connected device sare safe to use. Sadly that does not include safety certifications like UL/ETL, or TUV which may have implications for your home insurance depending on where you live, and for peace of mind, it’s always good to have a third verify your design for safety. Which brings me to the main point of this point, as a UL-certified dual-outlet smart socket, namely TP-Link Kasa Smart Plug, is currently on sale for $19.99 when ticking for the $10 discount coupon. [Update: They also […]

xDrill Smart Power Drill Supports Intelligent Speed/Torque, Laser Measuring, Digital Leveling (Crowdfunding)

Many home appliances now have smart functions, and in my cases, I fail to see the added value, and I’m not sure why I’d want/need a connected refrigerator with a touchscreen display. So when I first saw somebody make a “smart” power drill with a small touchscreen display I laughed. But after having a closer look, Robbox xDrill smart power drill could actually be a very useful device saving you time and helping work better. The touchscreen is used for settings but also serves as a level tool to make sure the drill is aligned horizontally or at the angle of your choice, and you can also set the drilling depth. There are also two lasers that measure distances, so you don’t need to use a measuring tape and pencil anymore. xDrill key features and specifications: Built-in microcontroller with WiFi and Bluetooth connectivity (is that an ESP32 inside?) Display – LCD touchscreen display Brushless digital motor Manual speed/torque lever (2000 […]
