Give the Clapper a Hand

Posted on by

While “The Clapper” probably first conjures images of low-budget commercials, it was still a useful way to remotely switch lights and other things around the house. But if the lights you want to switch weren’t plugged into the wall, like a ceiling fan, for example, The Clapper was not going to help you. To add some functionality to this infamous device, [Robin] built one from scratch that has all the extra features built in that you could ever want.

First, the new Clapper attaches to the light switch directly, favoring mechanical action of the switch itself rather than an electromechanical …read more

Smart Plugs Don’t Save You Energy, But Don’t Consume Much Either

Posted on by

Amazon Alexa, Google Home, and just about every electronic device manufacturer are jumping on the bandwagon of connected devices. They promise us the ability to turn on our toaster from another room, unlock our doors just by shouting at them from outside, and change the channel on our TV through perfectly enunciating a sentence instead of mashing the buttons on our remotes like chumps. And yet, despite all this new-fangled finger-less control, there is an unanswered question: does this technology save us energy in the long run?

For years we’ve been hearing about vampire power and all the devices in …read more

The Electrical Outlet and How It Got That Way

Posted on by

Right now, if you happen to be in Noth America, chances are pretty good that there’s at least one little face staring at you. Look around and you’ll spy it, probably about 15 inches up from the floor on a nearby wall. It’s the ubiquitous wall outlet, with three holes arranged in a way that can’t help but stimulate the facial recognition firmware of our mammalian brain.

No matter where you go you’ll find those outlets and similar ones, all engineered for specific tasks. But why do they look the way they do? And what’s going on electrically and mechanically …read more

Smart Outlet Cover Offers Lessons on Going from Project to Product

Posted on by

Going from idea to one-off widget is one thing; engineering the widget into a marketable product is quite another. So sometimes it’s instructive to take an in-depth look at a project that was designed from the get-go to be a consumer product, like this power indicating wall outlet cover plate. The fact that it’s a pretty cool project helps too.

Although [Vitaliy] has been working on this project for a while, he only recently tipped us off to it, and we’re glad he did because there’s a lot to learn here. His goal was to build a replacement cover for …read more

Finding ESP8266 Inside Big-Box Store IoT Plugs

Posted on by

When we buy new shiny toys, we usually open them up to at least have a look. [Scott Gibson] does the same, apparently. He found an ESP8266 module inside the EcoPlug brand WiFi-controlled wall switches.

The original device was intended to be controlled by a (crappy) app. He sniffed the UDP packets enough to send the on-off signals to an unmodified device, but where’s the fun in that? [Scott] gave it an upgrade by replacing the ESP8266’s firmware with his own and now he’s got a much more capable remote switch, one that speaks MQTT like the rest of his …read more
