There’s nothing quite like a real Christmas tree, but as anyone who’s had one will know there’s also nothing like the quantity of needles that a real tree can shed when it runs short of water. It’s a problem [RK] has tackled, with a Christmas tree water level monitor that …read more

Inspired by the good old days when your computer would boot directly into BASIC, [Le Roux Bodenstein] has created a handheld device he calls “DumbDumb” that can drop you into a MicroPython environment at a moment’s notice. If that doesn’t interest you, think of it this way: it’s a (relatively) …read more

For better or for worse, the tech world has fully committed to pushing as many of their products into “The Cloud” as possible. Of course, readers of Hackaday see right through the corporate buzzwords. It’s all just a fancy way of saying you have to poke some server over the …read more
A browse through his collected works will tell you that [El Kentaro] loves to build electronics into interesting enclosures, so when he realized there’s enough room inside a 150 ml plastic syringe to mount an ESP8266, a battery, and a copious amount of RGB LEDs, the “Packet Injector” was the …read more

Even simple robots used to require quite a bit of effort to pull together. This example shows how far we’ve come with the tools and techniques that make things move and interact. It’s a 3D printed rover controlled by the touchscreen on your phone. This achieves the most basic building block of wheeled robotics, and the process is easy on you and your pocketbook.
We just can’t stop loving the projects [Greg Zumwalt], aka[gzumwalt], is turning out. We just saw his air-powered airplane engine and now this little rover perks our ears up. The design uses the familiar trick of …read more

[Mike] is the only one in his house who drinks coffee, and uses a simple single-serving brewer with no auto-on feature. And since no one really wants to have to stand around making coffee in the morning, [Mike]’s solution was to IoT-ize his electrical socket.
The project consists of a relay board controlled by an ESP8266-packing Adafruit Huzzah. It’s all powered by a 9V power supply with a regulator supplying the relay coil and Huzzah with 5V. [Mike]’s using CloudMQTT to communicate with the outlet.
We often see these automation projects hit a wall when it comes to adding a …read more

Did you forget about Valentine’s Day? Do you need a quick project to get ready for Valentine’s Day? [Becky Stern] has you covered. She’s whipped up a neat Internet-enabled Valentine project which should be pretty quick to put together.
At its heart (pun intended) is an ESP8266 microcontroller, in this case an Adafruit Feather Huzzah. Several layers of tissue paper heart are stitched together and cut out into a heart shape and then attached to a spring. A vibrating pager motor is used to shake the it when a signal comes in. Two buttons are used to send the message …read more

When you have a large software development team working on a project, monitoring the build server is an important part of the process. When a message comes in from your build servers, you need to take time away from what you’re doing to make sure the build’s not broken and, if it’s broken because of something you did, you have to stop what you’re doing, start fixing it and let people know that you’re on it.
[ridingintraffic]’s team uses Jenkins to automatically build their project and if there’s a problem, it sends a message to a Slack channel. This means …read more
