Giant interactive crossword puzzle uses 130 Arduinos

Tuesday, February 14th, 2017

In what is perhaps the most Arduino boards used together, 130 Arduino Nanos, (plus an Arduino Mega), 130 RFID readers, and 750 RGB LEDs power this interactive crossword puzzle.

As you might suspect, bringing a giant crossword puzzle to life was lot of work. If you’d like to know how much, you can see the process laid out in the video below. Like many great hacks, this project starts out with a lot of prep, making sure the mechanical pieces go together as they should. Everything is then wired and programmed, and on day six, it finally goes out the door, destined for the National Museum in Warsaw, Poland.

Each letter is equipped with an RFID tag. Under the table lies custom circuits consisting of a Nano, an RFID reader, and some WS2812B LEDs, which are connected to the Mega via an I2C interface. The Mega communicates with a PC, which reveals a visualization on the nearby wall.

Blank squares are dimmed. However, as a letter is placed down, the LEDs will light up in either green or red depending on whether it is correct. Once a word is completed, the entire table produces a disco-like animation with sound effects.

It’s quite a colorful display, and it looks like the kids playing with it in the “Anything Goes” exhibition love it! You can see more about this project in Robert Mordzon’s write-up.

Sort your M&Ms or Skittles with this ingenious machine

Monday, February 6th, 2017

Inspired by a YouTube video of another candy sorter, Willem Pennings decided to build his own version.

After nearly eight months of work, he now has a device that can separate M&Ms or Skittles into their respective color dishes. Control is accomplished via a pair of Arduino Nano boards along with two EasyDrivers and an RGB sensor. These actuate a small servo for mixing the candies, and a stepper motor to properly position the candy tube.

Besides designing the controls for the machine, everything is modeled beautifully in the NX10 CAD package. The results, as seen in the video, look extremely polished–and it’s quite soothing to watch these candies drop into their little bowls in automated fashion!

You can find more details on Pennings’ project page and check out the video that inspired him here. (more…)

Make your own 3D-printed sonic tractor beam with Arduino

Tuesday, January 3rd, 2017

From magic to science, man has long dreamed about being able to manipulate objects from a distance. People have been able to push something using air or even sound waves for a while, but University of Bristol researcher Asier Marzo and colleagues have come up with a 3D-printable device that can not only repel small items, but can also attract them to the source.

It does this using an array of sound transducers arranged in a dome shape at the end of a wand. The acoustic tractor beam is also equipped with an Arduino Nano, a motor controller board, a DC-DC converter, and a LiPo battery, among some other easily accessible components.

Basically, an Arduino will generate 4 half-square signals at 5Vpp 40kHz with different phases. These signals get amplified to 25Vpp by the motor driver and fed into the transducers. A button pad can be used to change the phases so that the particle moves up and down. A battery (7.3V) powers the Arduino and the logic part of the motor driver. A DC-DC converter steps-up the 7.3V to 25V for the motor driver.

Turn an old microscope into a live cell imaging device

Thursday, December 22nd, 2016

Microscopes are common pieces of equipment in laboratories (or even high school science classes for that matter), but making movies of living cells usually requires more expensive and specialized tools… until now. With a 3D-printed mount for a smartphone and an Arduino, researchers at Sweden’s Uppsala University have been able to retrofit ordinary microscopes to take time-lapse sequences.

To accomplish this, an Arduino was used to control a shutter for the smartphone to minimize light exposure when capturing intermittent images, while a heating unit was employed to maintain a constant temperature for the tiny organisms.

This robot is a cool new way to use cassette tapes!

Friday, December 16th, 2016

Though tape players persisted in vehicles for much longer than needed, cassettes are pretty much an obsolete format. That doesn’t mean they can’t be useful, as this project by Moscow-based media artist ::vtol:: shows.

His interactive robot, dubbed “pzr-10,” traverses a canvas littered with unwound tape, while two heads read the data off of it. Using an Arduino Uno, this data is then transmitted to the built-in loudspeaker and played aloud. Audio can be looped and processed in various ways, giving the user a unique audio experience!

Wrist thrusters let you fly through the water effortlessly

Friday, December 2nd, 2016

These small arm-mounted propeller units can carry a skin diver through the water with minimal effort.

YouTuber “PeterSripol” had only a week to prepare for his trip to Hawaii. Rather than purchase a set of fins or a snorkel, he instead hooked up two T100 thrusters that he had lying around to wrist straps. In his setup, these thrusters are controlled by a button interfaced with an Arduino that allows the user to select one of three power levels. (more…)

Making beats on a tiny Arduino DJ controller

Wednesday, November 30th, 2016

Electronic music seems to be ripe for hacking, as a new device can be fun as well as quite useful. Imgur user “fatcookies” decided to create a small DJ controller using an Arduino Nano, six push buttons, three potentiometers, and four configurable LEDs. (more…)

A 3D-printed lunar phase clock for your nightstand

Wednesday, November 23rd, 2016

“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…)

The Orbitalochka is a solar-powered satellite synth

Monday, November 21st, 2016

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.

The Synth Bike is a mobile music machine

Wednesday, November 9th, 2016

With a speaker on the back and a drum machine on the front, what can possibly go wrong?

After riding his bike home after a synthesizer get together, Sam Battle decided to actually combine these two pursuits, transforming an iconic 1973 Raleigh Chopper into a mobile synthesizer. Though his first try was rather crude, using an Oyster card stuck between spokes to trigger a switch, his aptly named “Synth Bike 2.0” looks pretty awesome.

Featuring eight–yes eightArduino Nano boards, the music’s tempo can be controlled by how fast you pedal, or set up to use a built-in clock. Other electronics include a Sparkfun WAV Trigger, some analog synth circuitry, a sampler, a digital oscillator, and a Music From Outer Space Echo module. (more…)
