Gaze Deeply Into These Infinity Mirror Coasters

Infinity mirrors have been gaining in popularity recently, thanks in no small part to the availability of low-cost RGB LED strips to line them with. Generally such pieces are limited to wall art, or the occasional table build, which is what makes these infinity mirror drink coasters from [MnMakerMan] so …read more

Building An ESP8266 Game System With MicroPython

After a seemingly endless stream of projects that see the ESP8266 open doors or report the current temperature, it can be easy to forget just how powerful the little WiFi-enabled microcontroller really is. In fact, you could argue that most hackers aren’t even scratching the surface of what the hardware …read more

Can You Live Without the WS2812?

As near as we can tell, the popular WS2812 individually addressable RGB LED was released to the world sometime around the last half of 2013. This wasn’t long ago, or maybe it was an eternity; the ESP8266, the WiFi microcontroller we all know and love was only released a year …read more

An ESP8266 Sundial For Your Wall

Hackers absolutely love building clocks. Seriously, there are few other devices for which we’ve seen such an incredible number of variations. But while the clocks that hackers build might blink out the time in binary, or write it out in words, they generally don’t feature hands. Apparently in 2019 it’s …read more

An over-engineered LED Sign Board

Never underestimate the ability of makers in over thinking and over-engineering the simplest of problems and demonstrating human ingenuity. The RGB LED sign made by [Hans and team] over at the [Hackheim hackerspace] in Trondheim is a testament to this fact.

As you would expect, the WS2812 RGB LEDs illuminate the sign. In this particular construction, an individual strip is responsible for each character. Powered by an ESP32 running FreeRTOS, the sign communicates using MQTT and each letter gets a copy of the 6 x 20 framebuffer which represents the color pattern that is expected to be displayed. A task …read more

IoT Traffic Light Is Cardboard Made Fun

Traffic lights! Kids love them, hackers love them, and they’re useful in industrial contexts to see if the giant machine is currently working or having a bad day. While the real deal are unwieldy and hard to come by, there’s nothing stopping you tackling a fun cardboard build at home.

In this case, the light is courtesy of WS2812b LED strips. They’re a great choice, as they interface easily with most microcontrollers thanks to readily available libraries. An ESP8266 runs the show here, serving up a basic web interface over WiFi. This allows the color of the various LEDs to …read more

Glow In The Dark Globe On A Spherical Screen

Terrestrial globes are almost a thing of the past in an era of Google Earth, but they can still be an exciting object worth hacking together, as [Ivan Miranda] shows with his glow-in-the-dark globe. It’s a globe, it’s a display, and it’s a great use of glow in the dark filament.

For the mechanical part of this build, [Miranda] used glow in the dark filament to 3D print a sphere and a reinforcing ring that hides inside. A threaded rod through the middle secured with screws and bearings make an appropriate spindle, and is attached to a stepper motor in …read more
