Poorly designed PCBs and enclosures that slowly cook the electrolytic capacitors within are a common failure scenario in general, but they seem especially prevalent in so-called Internet-of-Things devices. The SwitchBot Plug Mini that [Denki Otaku] took a look at after many reports of them failing is one such example. The location of the failed electrolytic […]
The QingPing Air Quality Monitor 2 is an Android-based device that not only features a touch screen with the current air quality statistics of the room, but also includes an MQTT interface that normally is used in combination with the QingPing mobile app and the Xiaomi IoT ecosystem. Changing it to report to a local […]

We’ve all been stymied by a smart thermostat, coffee maker, or other device which would work fine on its own but ultimately seems to be worse off for having an Internet connection — so when something actually pulls off this feat it’s quite noteworthy. [James] has a powerful set of connected speakers and while they […]
Back at the 2017 Superconference, Hackaday Managing Editor Elliot Williams started his talk about the so-called “Internet of Things” by explaining the only part he doesn’t like about the idea is the Internet… and the things. It’s a statement that most of us would still agree with today. If anything, the situation has gotten worse […]
For home use IoT systems, getting sensor data from tons of physical locations centralized to a single Raspberry Pi can be a difficult job, especially when considering the power consumption that’s necessary for doing it all over WiFi. When you’re using an ESP8266, for instance, swapping out batteries and accounting for connectivity issues can be […]
Many of the biggest stars are hesitant to do sequels, believing that the magic captured the first time around is hard to reproduce in subsequent productions. As I’m known (at least around the former closet that now serves as my home office) as the “Meryl Streep of Teardowns”, I try to follow her example when […]
