“Since there isn’t a supermoon everyday, make one for your bedside table!” This is exactly what G4lile0 set out to do using a 3D printer, an Arduino and some open-source tools.
The result was a moon phase clock consisting of a 3D-printed model and an LED strip to create the lunar phases. The lights are driven by an Arduino that precisely calculates which phase to show, as well as controls a 0.96″ OLED display revealing the date and time. Other electronics include an RTC module, a DTH11 sensor, a buzzer, and three push buttons.
The clock also features several modes, including an alarm, a wake-up light, a lamp, a thermometer, and a hygrometer. It can even help set the mood or start your next lunar rave with its relaxation and party-like special effects. (more…)
First of all, you just need to have Arduino account to use it. We completely removed the invite system, making it accessible to everyone. (Don’t have an Arduino account? Sign up!) This Arduino profile can also be used to post on our official Forum, buy products on our online stores, add comments on our blog, as well as create tutorials on the Arduino Project Hub.
What’s more, we’ve added the Library Manager to the online IDE; meaning, all the community-generated libraries are now available for your sketches without having to install anything. The Arduino community has written over 700 libraries, which you can browse through in the Library Manager and favorite the ones you like the most. All the libraries available in the Library Manager are automatically detected, so you’ll never need to install them to get your code to compile.
In the Red Dwarf TV series, Talkie Toaster is a monomaniacal talking toaster that tries to steer every conversation to the subject of toast. Now, YouTuber “slider2732″ has gone ahead and built a chatty appliance of his own.
To accomplish this, the Maker embedded a PIR sensor into the toaster’s lever that communicates with an Arduino Pro Mini whenever someone is nearby. The Arduino then reads sound files loaded onto an SD card and plays them through a 3W amplifier out to a speaker underneath. The replica is also complete with a circular panel on front, made out of “laptop screen material” with a sour cream tub’s lid, and equipped with a couple LEDs. (more…)
This model satellite is both strange and mesmerizing with folding solar panels and a FM transmitter.
Media artist Dmitry Morozov, aka ::vtol::, is back with his latest kinetic sound object, this one resembling a satellite. The Orbitalochka hangs from the ceiling and broadcasts sound via an FM transmitter and a built-in speaker. These noises are based on the position of the satellite in space, and it can even transmit a pre-recorded lecture by Sergev Kasich, who appears to reside in the satellite’s clear bubble.
This robust DIN rail mountable, Leonardo-compatible controller enables you to take your existing Arduino projects and swiftly transform them into permanent installations. The prototyping area and screw connectors allow you to install your own circuitry and reliably connect to accessories.
In the video below, Industruino co-founder Loic De Buck discusses these key features and more with Davide Gomba. (You can also find an extended version here.)
The team recently created an excellent tutorial showing how you to build an Arduino-based electricity consumption monitor with the Industruino PROTO platform. You can use it to measure AC power of your appliances, including a water cooker, TV, laptop charger, or anything else plugged into a wall socket. Alternatively, you can even use it in your electricity cabinet to evaluate the power consumption throughout your entire house (at least one phase).
The challenge is to measure an AC of a relatively high voltage (220-240V) with a direct current 5V Arduino MCU.
This may seem dangerous, but we will use a non-invasive Current Transformer (CT), so our Arduino remains galvanically isolated from the high voltage AC.
This prototype is based on the excellent open source project OpenEnergyMonitor. It uses parts of the its standard emonTx hardware and software to report the AC apparent power consumption, based on measurements of a Current Transformer as in the picture on the left. The original project also allows to measure 3 phase and/or real power, but for our prototype here we are only measuring the current of one phase, not its voltage which would require an AC/AC adaptor.
Bouncing a laser off of a spinning mirror creates an amazing effect with smoke and fog, but YouTuber “Normal Universe” made it even better with an Arduino.
This video starts out by introducing the concept of “laser sky,” which seems like a fun idea. There is, however, a chance that the mirrors wouldn’t spin, potentially pointing a laser continuously at a bystander, possibly damaging his or her eyes. To prevent this, the YouTuber added a photoresistor and LED to sense the spinning mirrors, then programmed an Arduino Uno to cut off the laser if it’s stopped for whatever reason. (more…)
Self-driving cars seem to be all the rage these days in technology circles, but, as part of Cal Hacks 3.0, researchers have instead figured out how to drive a car using brain waves. This hack takes the form of an EEG headset that translates brain signals into “stop” and “go” commands, with a head-mounted gyroscopic sensor used to tell the steering wheel how to turn.
A radio link using an Arduino transmits these signals to the car’s new physical controls. This takes the form of linear actuators for the brake and accelerator pedal, and a windshield wiper motor for the steering wheel. (more…)
After an accident, Ethan Kadish was paralyzed. His friend, 14-year-old Jacob Smilg, came up with a simple device to help him communicate.
Several years ago, Kadish was struck by lightning, and lost control over his body. Communication with the world took the form of eye blinks for “yes” and “no,” which gave Smilg an idea for a revolutionary, Arduino Uno-based gadget that could help him communicate with people not familiar with this method.

In order to convince his kids to stay in bed just a little longer, Maker Ralph Crutzen has created a “wakeup light” using an Arduino Mega and an RGB LED strip.
Those of us that have toddlers know that they can wake up very early. If you’d like to get some more sleep without leaving them unsupervised to dangerously play with your electronics and power tools, then a “wakeup light” could be a good solution. (more…)
Stanford researchers led by post-doctoral fellow Nariman Farsad have built a machine that sends text messages using common chemicals.
If you’re building a project, and need to send a signal from one component to another, solutions generally involve wiring them together, or some sort of radio, perhaps Bluetooth or Wi-Fi. Farsad, however, has been working on something entirely different. His system uses commonly-available chemicals to turn a liquid, either basic or acidic, in sequence as a binary communication protocol. (more…)
