Aumi is a new night light for your smart home

Aumi is a Bluetooth-enabled, multi-color LED night light that you control with your phone.

Fear of the dark, also known as nyctophobia, is an all too common developmental challenge for children. And although it is most typical for younger kids, even adults can be afraid of entering a pitch-black room or what may be lurking under the bed. Fortunately, this is where night lights have become an age-old remedy, offering just enough of a sense of security while illuminating the general layout of the space without having to turn on an entire ceiling lamp.


While the wall-mounted units have evolved ever so slightly throughout the years, they all still lack in terms of aesthetics and functionality — especially when compared to the smart home appliances of today. In an effort to change this, Maker Mitch Thompson has developed what he calls Aumi — a Bluetooth-enabled, multi-color LED night light that plugs into any outlet and be controlled right from a person’s smartphone.

Like others before it, Aumi features an LDR sensor that automatically triggers the light when it detects darkness. However, what separates Thompson’s innovation from those on the market today is that the sleek, puck-like unit is equipped with fully-adjustable RGB LEDs. Meaning, when paired with its accompanying app, users can choose from over 16 million color options. (That sure beats the traditional white glow.)


What’s more, Aumi allows users to turn on/off, dim and set timers for their lights all from their handheld gadget, as well as receive notifications like texts and calls. Or, should someone prefer to manually modify the brightness, this can be done by simply turning its aluminum bezel.

Based on an ATmega328P, the light packs a built-in LiPo battery that can last between eight to 10 hours per charge — plenty of juice to last through the darkest hours. Another nice feature is that it was designed with utmost portability in mind. In other words, children can safely leave it lying on their nightstand, and when they need to get up, just grab their Aumi and proceed out of the room. And parents, aside from being an ideal bedtime companion, Aumi can also be employed for some accent lighting around the house.


Sound like something you or your child would love to have? Head over to Aumi’s Kickstarter page, where Thompson is currently seeking $32,476. Delivery is expected to begin in December 2015.

Harpa is an origami night light

Harpa – which recently surfaced on the official Arduino blog – is a large hand crafted elephant lamp shade with Wifi controlled RGB LEDs, microphone, speaker and a custom designed iPad application to teach children about color.

Originally conceived as a small paper origami elephant with blinking LEDs, the model was designed in Blender and 3D printed as a solid wireframe using the Shapeways service.

“The idea with the wireframe was to hand sew all the faces onto the model, that way I could try different materials as well as save money on the 3D print (printing filled surface faces would cost thousands at that size),” Harpa creator Trent Brooks explained in a recent blog post.

“The electronics are driven by an [Atmel-based] Arduino Mega 2560 board (ATmega2560 MCU) with Ethernet shield for network control. Connected to the board is a 50cm 5V RGB addressable LED strip with 30 LEDs, a 3.3V microphone module for sound detection and an 8ohm speaker for playing back generated ‘white-noise’ audio. Total cost for the all the electronics was less than $100.”

According to Brooks, the custom iPad application allows children to learn about color by selecting from various presets. Essentially, the primary interface displays a grid of colored elephant heads. When one is selected, the name of the color is pronounced, while the main night light changes color.

“There is a hidden control panel in the iPad app which allows me to change some of the more advanced features. For example, I can switch the ‘white-noise’ speaker on,” he added.

“[Plus] I can switch on audio reactive mode which uses the microphone to detect variations in sound level to change the LED colors (great when playing music, not so much for a sleeping baby); I can also change the number of LED’s, brightness, saturation and have them auto cross fade into different colors.”
