PIXIE is an Arduino-based NeoPixel watch

Tuesday, September 20th, 2016

Not looking for a smartwatch? PIXIE is an Arduino-based NeoPixel wearable device that not only keeps time, but will also keep your geek cred intact.

You won’t find any numbers on this watch; instead, PIXIE uses LEDs to reveal the time–hours in blue, minutes in red, and seconds in green. Beyond that,  a capacitive touch switch on its strap will activate a flashlight mode.

In terms of electronics, PIXIE is equipped with an Arduino Pro Mini, an Adafruit NeoPixel Ring, a real-time clock module, a lithium-ion battery, and a few other components–all housed inside a simple cardboard box with a piece of transparent plexiglass. (more…)

Capture time-lapses with a steel and aluminum camera slider

Tuesday, September 20th, 2016

Using an Arduino, along with a stepper motor and ball bearings, YouTuber GreatScott! has created a very smooth camera slider.

Time-lapse sequences can be interesting on their own, but if you can add motion to the camera, this adds a really neat element. To give a little extra flair to his video production, GreatScott! built his own motorized slider using stainless steel and aluminum parts. Movement is accomplished via an Arduino Nano controlling a stepper motor, and ball bearings are used to keep the shots smooth. You can see the results and process in the two-part video sequence below. (more…)

The MR-808 is a robotic drum “synthesizer”

Monday, September 19th, 2016

The MR-808 robotic drum machine looks like a gigantic Roland synthesizer, but plays with real instruments!

The Roland TR-808 was released in 1981 and was meant to replace a human drummer for practice purposes, but was instead used to produce music itself, helping to birth the electronic, techno, and hip hop genres. Moritz Simon Geist and the Sonic Robots collective, however, decided to turn this on its head, with a machine made to look like a gigantic ‘808, but containing real instruments.

With a variety of hardware, including an Arduino Uno and Mega, an audience can program the MR-808 using a tablet and get down to the grooves they create themselves!

Analyze your world with the WiSci portable spectrometer

Friday, September 16th, 2016

Spectroscopy is an incredible tool for chemical analysis–and now you can make your own Bluetooth-enabled device with an Arduino Pro Mini.

If you took advanced chemistry classes, you may have had the opportunity to work with a spectrometer. It probably seemed like a magical gadget, identifying the chemicals in a substance through its light characteristics unlike the experimental methods you previously had to use.

Using off-the-shelf components–including an Arduino, a Bluetooth module, an LED, optical filters, and a LiPo battery–housed inside a 3D-printed case, the WiSci aims to take this tool out of the lab, and into the “real world.” By following the instructions on its project page, you can build one for just under $250.

A community-made, Arduino-powered interactive town map

Thursday, September 15th, 2016

MapProject

A group of students from Farmington, Connecticut partnered with artist Balam Soto and master teachers Earl Procko and Jim Corrigan to create a community-based sculpture project that allows people to explore the sights, sounds and history of their town through new media.

The installation runs on Arduino Uno and XBee, and is comprised of two panels which act as viewing screens for multiple visual projections. Visitors can interact with the display and manipulate the images using 24 buttons placed on the physical map. Plus, they are encouraged to record and add their own stories and memories of Farmington to the ever-growing multimedia library. (more…)

PyroGraph is a plotter that burns images on paper

Thursday, September 15th, 2016

Inspired by the traditional thermal printers, the PyroGraph is an experimental plotter that uses a soldering iron to burn images onto paper.

Created by the team of Bjørn Karmann, Lars Kaltenbach and Nicolas Armand, PyroGraph works by analyzing any picture and then converting it into dots that are scorched onto a piece of paper with a 450 °C tip. The time of contact between the iron and the paper determines the grayscale of the dot?—?the longer it presses against the paper, the darker the dots get.

The machine uses a paper roll (so the length of the printed piece can then be up to 100m) and a head moving on a fixed x-axis, controlled by servo motors and a custom software developed by the group of Copenhagen Institute of Interaction Design students.

But that’s not all. The PyroGraph will also listen to the ambient noise within its environment to make a connection between the space and the printer. The drawings will be distorted depending on the sound activity of the room in which it will be displayed.

You can read more about the project here, and see it in action below!

Build your own robotic arm out of cardboard

Wednesday, September 14th, 2016

From our Chairigami Maker Faire booth furniture to Google VR headsets, we’ve seen various use cases for cardboard. Added to that list is a robotic arm, courtesy of Uladz Mikula.

According to the Maker, the design can be replicated in two hours using Arduino and four servo motors. Aside from the electronics, the project also calls for a piece of hardboard for the base and three clips. (more…)

Play the guitar on a guitar bag

Wednesday, September 14th, 2016

While exploring new tangible interfaces, designer Martin Hertig wanted to do something a bit different. He chose to transform the zippers on a guitar bag into a fully-functional instrument. Rather than strum the strings of the guitar, he simply pulls the bag’s zippers to jam: one zip for playing notes or chords, another for changing the bar, and a third for the vibrato.

As Hertig explains, the case was converted into a MIDI controller using an Arduino and conductive thread stitched along the zipper, while a Raspberry Pi synthesizer hidden inside produces the guitar sounds. (more…)

Arduino-powered roller blinds

Tuesday, September 13th, 2016

Tired of adjusting your blinds depending on outside lighting conditions? YouTuber “Dial” has the solution!

Perhaps you’ve seen hacks where people hook a servo up to blinds to flip them open and shut. If, however, you have the kind of blinds that need to be pulled all the way up to let light in, things become a little more tricky. Dial serves up an incredible solution in the video below, with a servo fixture that holds the balls on a blind’s roll up rope in a setup that could be described as the inverse of how a bicycle sprocket works.

Arduino Wiring is the latest addition to Windows 10 IoT Core

Tuesday, September 13th, 2016

IMAGE11

Last year, we announced on the blog how Windows became the first Arduino certified OS and introduced Windows Virtual Shields for Arduino and Windows Remote Arduino. Now, engineers at Windows have published a blog post showing how you can use Windows 10 IoT Core to create or port Arduino Wiring sketches that will run on supported IoT Core devices. (more…)
