Rewind: 30 Maker musical masterpieces from 2014

There’s music making and then there’s making music. From gloves that play tunes to modded printers that blare songs, Makers have proven that just about anything — and we mean everything — can be transformed into sound. And well, as you can tell from our #ThrowbackThursday chippy takes on ‘90s hits, we love music.

Not to mention, a number of musicians have even become advocates of the burgeoning Maker Movement as of late, most notably Sir Mix-A-Lot and will.i.am. For one, the technophile founder of The Black Eyed Peas has offered a ringing endorsement of the DIY culture, recently emphasizing that, “Every young person is going to be inspired to be a Maker from now on. It’s like how everyone used to want to be a musician, an actor, an athlete — but a maker is what people are going to want to be.”

With 2014 coming to a close, we’ve decided to list some of our most favorite and quite impressive musical masterpieces from the last 12 months.


A poncho that literally will help you sing in the rain

Kong_Liana_Radio_01

Carnegie Mellon student Liana Kong recently designed a DIY musical rain poncho using an Arduino Uno (ATmega328), FM tuner and flexible speaker. The poncho is capable of controlling the radio in a number of ways, including: hood up/down – power, colorful snaps – different station presets and hood strings – volume.


This obsolete typewriter plays some sweet music

dorthe_04

Maker duo Lasse Munk and Søren Andreasen have created a musical typewriter that transforms ordinary sentences into sound. 

Known as D.O.R.T.H.E (short for Danish Orchestra of Radios Talking and Hacked Engines), the platform is constructed out of old, discarded electronics. In essence,the hacked platform can be thought of as an electronic music box — with each word acting as a pin to create a sound or tone. Every letter on the typewriter is essentially a trigger, as these letters are connected to an Arduino Mega (ATmega1280). The data is then analyzed, where the software then processes and translates it into a musical sequence. More specifically, D.O.R.T.H.E. transforms the number of letters in a word to a certain music pitch, although it is also capable of dealing with basic emotional states such as joy, discomfort, fear and happiness.


Turning chicken nuggets and sushi into music

spazzkid-makey-makey-640x360

While dipping a chicken nugget into sauce or touching sushi may not be the most conventional way to create music, if there is one thing that the ATmega32U4 MCU based MaKey MaKey has taught us, is that nearly anything can be transformed into a MIDI trigger. This includes the tops of cats’ heads, plastic mannequin parts, cacti, rubber finger monsters, and old-school Polaroid cameras, as demonstrated by musician Mark Redito (also known as Spazzkid).  While one would assume that jamming away on some raw fish or dunking a piece of chicken into sweet ’n sour sauce may not produce the most desirable sounds, this performance is anything but.


Piano hack adds another dimension

ff2p909hw8qw3ie-large

A modder by the name of Capricorn1 has added a rockin’ visual dimension to his already impressive musical skills by using a piano’s MIDI output to drive Edison bulbs. Capricorn1 hung the bulbs from a rod of electrical conduit pipe, while threading the wires to a DB25 connector. The lights were controlled by an Arduino Mega (ATmega1280), along with a custom shield and optocoupler to handle zero cross detection.


Cathedral-like sounds packed into a toaster-sized device

midi

Although it may sound like a pipe organ from St. Patrick’s Cathedral, Maker Matthew Steinke has packed all of those tunes into a 4”x13”x14” MIDI-controlled, portable device. Instead of using pipes and a wind chest typically found in cathedral-esque organs, the toaster-sized device utilizes a combination of electromagnets and steel tines. Impressively, the Tine Organ is capable of producing 20 chromatic notes in full polyphony, starting at middle C, and can be attached to a standard keyboard or a synthesizer smartphone app. An [Atmel based] Arduino unit housed inside the device receives the MIDI input that controls 20 polyphonic software oscillators, which is then sent though a trio of Darlington drivers to the magnets.


 A wearable machine turns tattoos into music

Moscow-based artist Dmitry Morozov — also known by many as ::vtol:: — has created a unique sound controller to read musical scores implanted in tattoos. The scanning instrument is comprised of a metal railing, hand controllers and parallel black line sensors that move along the arm using a stepper motor. In addition, it is equipped with a Nintendo Wii remote control and an Open Sound Control to enhance the sound possibilities. A stepper motor guides the device along the inked lines, while the length of each bar coincides with the duration of an emitted sound. On the hardware side, key features of the musical creation include an Arduino Nano (ATmega328), a Nord Modular G2, a Symbolic Sound Kyma X, and a six-channel PVC pipe sound system.


Obsolete computer parts turned into marvelous music

waste-orchestra-tech

A group of Illinois-based Makers hailing from Makerspace Urbana have unveiled a way to take outdated technology and turn them into pieces of musical instruments. The Electric Waste Orchestra project strives to “manipulate the voltage flowing through circuit boards and use those signals to make music” out of components that would’ve otherwise ended up at the dump. The team transformed an old keyboard number pad, six hard-drives, an [Atmel based] Arduino board and some software into a fully-functioning guitar jamming along with a modular synthesizer.


 A series of stepper motors belt out some Guns N’ Roses

maxresdefault

Sweet Stepper of Mine! Jeremy Weatherford repurposed two stepper motors to play high-tech versions of some of the classics and you have to hear it to believe it. At the core of the Maker’s device sits an Iteaduino MEGA 2560 (ATmega2560) and a series of percussion linkages.


Coffee cups and Arduino unite to make an instrument

illumaphone-view1

Bonnie Eisenman needed to produce a final project for her electronic music class. So, as a software engineer by trade, the Maker decided to explore her creative side and just like that, the Illumaphone was born. The Illumaphone is a light-based spatial musical instrument that be played by simply waving your arms. Six coffee cups serve as the inputs (aka “light funnels”), with each one keyed to a different pitch. Light levels determine volume and vibrato; as a result, once a cup measures the amount of light, that data is translated into the sound emitted. By moving your hands over a cup, volume and vibrato of a tone are created in relation to the light present. On the hardware side, an Arduino Uno (ATmega328) powers the electronic instrument and receives information from a set of six photo resistors.


Wearable Knitgadget controls your musical devices

smart-yarn

Royal College of Art student Yen Chen Chang recently debuted the Knitgadget, a wearable glove that allows users to control various devices, musical or otherwise. The glove is comprised of conductive yarn that’s 80% polyester and 20% stainless steel (and 100% pure awesomeness). Chang knit and crocheted a series of objects that control devices by rubbing, pulling and stroking. When manipulated, the overlap of the metal fiber causes the textile to change conductivity which is then measured by an Arduino and communicated to the gadgets.


Drumming up some table tunes

499823868_1280x720

In one of their latest demonstrations of how the ATmega32U4 based Touch Board can be connected to almost anything, the Bare Conductive crew has transformed ordinary items found throughout the kitchen — oranges, a pan, a toaster, a coffee maker, a tea kettle and even some silverware — into sound. Put them together and well, food won’t be the only thing you’re making on the counter!


Making music with the MaKey MaKey Monome

f0gy98yhxb3rpz9-large1

In an attempt to create a complex musical instrument with inexpensive parts and a simple process, Maker JDeboi has developed one rockin’ device: the MaKey MaKey Monome! As seen at this year’s World Maker Faire, JDeboi utilized the ATmega32U4 powered platform to create a futuristic instrument that looks like it was transported back from the year 2114! Using Makey Makey as its brains, JDeboi implemented a partnership of copper tape, NeoPixels, and cardboard to bring this monome to life. First using the NeoPixels and cardboard, she established an LED lattice that would serve as the base of the project. The Maker recommends using three different colored wires for GND, 5V, and data.


Turning old floppy drives into tunes

fk6n132hz6t6x91-medium

We said a flip flop the flippie the flippie to the flip flip flop a ya dont stop the makin’ of a floppy disk jukebox! Remember that irritating etching noise that aging floppies emitted when they would boot up? Well, Chris Fry has harnessed the sonic power of these old drives and turned them into some musical masterpieces. The Maker blew the dust off of eight floppy drives that he collected and began researching on Instructables how to repurpose them into a programmable musical machine. With the power of an Arduino Uno (ATmega328) and a hefty ATX power supply, Fry had his drives linked up and ready to jam.


These house plants can play tunes when they’re touched

3026612-inline-i-1-hacking-house-plants

Inspired by what they saw at a recent Maker Faire, Fast Company’s Natalia Rodriguez and Jihyun Lee hacked some of their typical houseplants to play various musical notes depending how they are grabbed. For example, when someone touches the stem the note is different than when they touch its outer leaves. When grabbed with two fingers instead of one, the sounds are different; same goes for other hand positions. The Makers reproduced a version of Disney’s “Touche,” the technology former Disney researcher Ivan Poupyrev and his team built to encode the frequencies that conductive materials like water, human bodies, and plants, among other materials carry whenever they are touched by a human — using a tutorial from Mads HoBye, Instructables‘ artist-in-residence, who hacked his own version using a small Arduino. While the team aspired to keep things organic and the plants as far from the computer as possible, the team utilized an Arduino Uno (ATmega328) to allow the plants to speak to the computer wirelessly.


DrumPants puts an entire band in your pocket

drumpants

Ever catch yourself drumming on your thighs? Your table? Your desk? Your steering wheel? Now, starting a one-man band is as simple as wearing this musical kit. DrumPants, dubbed by its creators as “the world’s industrial quality wearable musical instrument,” transforms your outfit into a full ensemble with 100+ built-in high-quality sounds. DrumPants consists of two wearable sensor strips and a control box (embedded with an Atmel | SMART ARM Cortex-M3-based MCU) that affixes to your attire, allowing you to play a beat by simply tapping your body. The pair of sensor strips can easily be attached and removed from any item of clothing, making it the ideal portable instrument. In addition, the wearable device’s companion app can adjust the tone and pitch of each sound effect and enables users to upload their own customized effects. Wearers even get the functionality of a looping pedal built right into their shoe. The DrumPants kit is designed to work with any app that accepts MIDI or OSC signals, therefore providing users the ability to record, loop and edit their musical masterpieces.


Drawing musical MIDI

img_1921

Earlier this year, a team led by Alex Haff of NYU’s Science of Music school debuted a DIY paper circuit project, aptly dubbed “Draw MIDI.” The digital-based platform uses capacitance sensing to collect electrical signals from a pencil-and-paper keyboard. The signals are converted to MIDI with an Arduino Uno (ATmega328) that sends the code to a PC via a Max patch.


A 3D feather touch MIDI keyboard

6efc73788c209b7872a2921e903e62b9_large

The Kyub is a Maker-friendly MIDI keyboard kit that can be easily assembled by just about anyone. Powered by a Teensy 2.0 (ATmega32U4),the open-source device allows users to simply attach one or multiple Kyubs to a computer synthesizer or digital audio workstation for to jam alone, with friends, or even for a full-out composition.


 Drum anything, anywhere and make real music

908589

Ever catch yourself drumming your pencil or utensil on a tabletop? Thanks to Korg’s ClipHit, you can now bring those rhythmic beats to life. ClipHit’s newly-unveiled concept allows you to take everyday objects and turn them into a portable, electronic percussion instruments by simply attaching the three vibration-sensitive clips to a desk, table or any other nearby surface. Equipped with motion sensors, the clips analyze and monitor how hard you strike an object with a drumstick, pencil or even your fingers, while an embedded sensor in the control unit enables it to be played the same way. A user may also trigger a variety of built-in sound samples — kicks, snare, toms, and cymbals — and select a series of rock, pop or standard drum sets.


 This onesie turns you into a walking MP3 player

byborre-bbsuit-wifi-1-537x402

Dutch designer Borre Akkersdijk aspires to usher in a rather unique form of 3D-printed garments: a onesie capable of turning its wearer into a mobile Wi-Fi hotspot. Akkersdijk believes that the current generation of wearable technology — ranging from smartwatches to fitness bands — isn’t so much something you wear as it is something you attach to yourself. His project, named BB.Suit, was created in an effort to turn what calls “carry-able technology” into a much truer wearable form. In doing so, he hopes it would be able to establish a platform where wearers, people around the suit and even those online could all interact with one other in a dynamic, interactive manner. The first version of the suit — which made its debut back at SXSW — featured electrical threads woven into its fabric along with a musical library and GPS system. In collaboration with the online platform 22tracks, musicians around the Austin-based event were able to upload tunes directly onto BB.Suit, giving the term ‘walkman’ an entirely new meaning.


Hacking instruments with nothing but junk

warmyurisuzuki

Maker Yuri Suzuki recently collaborated with South African artists Bogosi Sekhukhuni and Neo Mahlasela, along with creative technologist Nathan Gates, to create a slick musical installation entitled “Warm Leatherette.” Suzuki and Gates devised the set of instruments by using nothing but electronic waste readily found in the streets of downtown Johannesburg — including old cellphones, televisions and cassette tapes. After collecting these obsolete devices, the team went onto upcycle them into a Maker-iffic spread of new musical tools. For instance, Suzuki connected an old TV to an Arduino for an electric drum sound, constructed a keyboard from Nokia phones, and pieced together a cassette tape guitar with variable speeds and sounds.


Move with the music — literally

FMEMYZNHUJ96T1T.MEDIUM

A Maker by the name of “BBrodsky” has created an MP3-equipped workout shirt powered by an Arduino LilyPad (ATmega328P), which utilizes the music player and an accelerometer to detect whether or not the wearer is moving. If so, it plays his or her music. According to BBrodsky, the goal of the system is to promote an active lifestyle for wearers.


MIDI drum glove keeps the beat with FLORA



force___flex_midi-drum-glove-34

Designed by Adafruit’s Becky Stern, this MIDI drum glove is powered by the versatile FLORA platform (ATmega32U4). By simply tapping his or her fingers, a wearer can drop a beat like Iggy while looking like Michael.


MIDI dot-matrix printer does the Hackerena (and many more)

maxresdefault-1

There is no doubt that you remember the inescapable ‘90s hit, The Macarena. The pairing of a catchy beat and a simple dance turned the Los Del Rio smash hit into a national phenomenon. Now, 20 years later, we can reminisce about the tune all thanks to one Maker and his MIDI compatible dot-matrix printer. A hacker by the name of MIDIDesaster has made a habit of turning DMPs into musical devices ranging from an ingenious cover of Eye of the Tiger to Jingle Bells. The modified printer uses an ATmega8 MCU to interpret inbound MIDI data and then feeds the information to an FPGA that essentially tunes the printer.


Play 8-bit chiptunes from your living room sofa

990365310f630e9618f47b8f48fa8ced_large

Ah, chiptune music. Who could forget the iconic synthesized electronic sounds of ’80s gaming? Well now, the Assorted Wires crew is letting your deliver those 8-bit tunes with the Lo-Fi SES, a hackable device. Consider yourself warned though, the open-source instrument will surely spark up some NES nostalgia! Based on an Atmel AVR MCU, the Lo-Fi SES replicates the shape of a good ol’ SNES controller, whose buttons are used to trigger samples, change tempo, as well as play, record and delete tracks. The controller, which is the heart of the Lo-Fi SES experience, comes equipped with a default playlist of onboard sounds including a lo-fi drum set.


Blast your favorite tunes with the Touch Board Boombox

dsc03594_1000x500-480x321

Our friends over at Bare Conductive recently teamed with Jude Pullen of Design Modelling to develop a trendy boombox that perfectly demonstrates the widespread capabilities of their ATmega32U4 based Touch Board. Comprised of simple cardboard box along with some stenciled on Electric Paint and attached to a Touch Board, the Makers were able to get this stylish creation to flood the streets of London with some of their favorite MP3s.


Drop a beat with this ATmega328 based drum box

tumblr_ngmgpfm9ud1tktcabo3_1280-1

Maker Ole-Birger Neergård has devised a nifty DIY drum machine, the 7-BIT BEAT BOXXX, which is capable of laying the rhythm down for everything from ‘70s funk to modern-day hip-hop tunes. The retro synth-like box’s built-in metronome activates the 7-bit drum samples with every click. In addition, the drum machine is based on an Arduino Uno (ATmega328), encased in a series of mahogany and white acrylic panels. The Lo-Fi drum machine is programmed with nine different (and easily replaceable) 4-second drum samples, as well as features four buttons. The top-left button changes the sounds from three different sample banks, while the other three are responsible for activating the sound bites: big drum on the bottom left, snare on the bottom right, and hi-hat on the top right.


Arduino turntables transform Makers into DJs

beatblox

A Swedish designer by the name of Per Holquimst is redefining the use of the old-school turntable. No longer will the instrument solely play music; in fact, his Arduino tangible interface turntable will have you forming beats from scratch in no time! Each machine contains five digital distance sensors in its wooden arm. The instrument can analyze up to 15 different blocks, therefore allowing complex rhythms to be established. These sensors interpret the locations of the blocks and relay that data back through the Atmel based system, making music based on certain pre-programmed metrics. As the user adds a block to the deck, the distance sensor plays a sound; thus, creating a wildly different melody is as simple as moving a block an inch to the left on the rotating wheel.


This installation lets you play city sounds by stepping

f440mkii3h4wj5c-medium-2

Ever since the days of Tom Hanks playing the giant piano inside FAO Schwartz, we’ve all wanted to step on floor keys and make tunes. Now, what if those “keys” could emit city, pow-wow or drum kit sounds? Thanks to a new audio installation designed by Chelsea Stewart and Eden Lew at the School of Visual Arts Products of Design MFA program, you can! Called “Sound Steps,” the project was designed under the guidance of Adafruit’s Becky Stern as the Maker explored the use of Arduino units in rapid prototyping of new product interactions. Inspired from their recent move from to New York, the duo decided to collect sounds around the city. The sounds were then uploaded to its farm, which consisted of four 1.25’ x 0.75’ x 6’ wood boards, a few extra pieces for an interior bracing as well as MDF material to create the platform top. Sound Steps is comprised of a 9 x 9 fabric square matrix, with each square connected to a Bare Conductive Touch Board (ATmega32U4). The project invites bystanders to walk barefoot across the interactive platform to discover the city audibly.


 Become a conductor of your own air symphony

Created by Ootsidebox’s Jean-Noël, 3Dpad is a sophisticated touchless gesture control interface with a depth perception of 10cm. Based on an AT90USB1286, the slick device is equipped for a wide-range of applications, including artistic expression, a game console, or in this case, an air controller for any electronic instrument.


This embedded ukulele can teach you to play chords and songs

major_play-1

Designed by Cornell students Raghav Subramaniam and Jeff Tian, ukule-LED is equipped with 16 NeoPixels that are situated along the first four positions of the fretboard. This allows those playing the device to easily learn how to play each chord. All of the 16 LEDs are connected in series to a single pin on the ATmega1284P that sits on a board mounted to the bottom of the ukulele along with power and serial.  ukule-LED has two modes of operations: “Play” and “Practice.” First, in “play” mode, the user can feed the system a song file, a text file that contains the tempo, time signature, and an ordered listing of the chords in a song. The ukulele will then light up the correct chords at the correct times in the song. (Think of it like Guitar Hero.) While in “practice” mode, the user can specify a single chord, which is lit up indefinitely. For those more experienced musicians, the ukule-LED can still serve as an excellent chord reference.

Rewind: Oh. My. God. Becky, look at those wearables…

From GPS logging dog harnesses to MIDI drumming gloves, Adafruit’s Director of Wearable Electronics Becky Stern has unveiled some pretty wonderful wearable projects over the past couple of months. So much so that we’ve decided to pay homage to the LED-lovin’, gadget-glowin’ Maker by showcasing several of our favorites.

While the inherent versatility of Atmel’s MCUs have made our silicon a favorite amongst engineers for next-gen smart devices, evident by Becky’s latest designs, they have also increasingly emerged as the go-to choice for Makers creating DIY wearables.

What would a bright night on the town be without an appropriate getup of man’s best companion. Here, Becky transformed once-ordinary Doggles into a paw-some pair of cyberpunk-style glasses with a rotating laser. Using a Trinket 3v MCU (ATtiny85), a set of clear dog goggles and a laser diode as the center of the device, this invention will surely be a hit on the scene.


Light-Activated Pixel Heart

light-activated-pixel-heart

Talk about wearing your heart on your sleeve, or in this case, shirt. The embedded GEMMA and light dependent resistor detect when a wearer’s NeoPixel heart is uncovered, and just like that, triggers the heart light on.


Superhero Power Plant

Zipper Switch

braincrafts_zipper-switch-03

Zippin’ awesome! In one of her latest projects, Becky explores yet another innovative way of turning otherwise relatively dull clothing into more fun, interactive attire. Take zippers, for instance. Here, the super talented Maker transformed them into a momentary switch for activating lights, sounds, and more using stainless steel conductive thread. As the zipper pull travels along the teeth, two pads of conductive thread are bridged, momentarily creating an electrical connection. This connection can be sensed by an Atmel based MCU, such as the FLORA or GEMMA, with an activated internal pull-up resistor.


If you’re feeling inspired to make your own project using Adafruit’s FLORA, GEMMA and Trinket wearable electronics platform, explore everything there is to know here.

This Magic 8-Ball has attitude — and an ATmega32U4

Ah, the Magic 8-Ball. Who could ever forget the hollow plastic sphere that emerged as a pop culture icon dating back to the 1950s? Indeed, a fictional fortune-telling device, it was often used for comedic advice given its inaccurate and otherwise statistically improbable answers.

F8PPQY0I2VLGH8Y.MEDIUM

First developed and manufactured by Mattel, the oversized, black-and-white pool ball provided responses to “yes or no” questions via a 20-sided die floating in dark blue fluid — whichever side that floated to the top was the answer. However, a Maker by the name of “e024576” has put a new spin on the vintage toy, replacing the die and liquid with an OLED display and a FLORA microcontroller (ATmega32U4).

F0T6PKMI2XTQ44A.MEDIUM

While its exterior is pretty much identical to that of its ancestor, Makers can now edit or add answers of their choosing and are not limited to just 20 outcomes. Simply pick it up, ask a question and turn it over. To much surprise, the ball may have a little more attitude and snarkiness than that of your childhood. Watch it in action below!

Ring in the holiday season with this festive DIY hat

Can you believe it? It’s already December! And, what better way to kick off the official holiday season than with this slick wearable created by Maker (and hat aficionado) Barbara Eldredge.

Our friends over at Element 14 initially brought her Atmel based Jaunty Fascinator to our attention a couple weeks back after it had been crowned victor of their recent Hats Off Design Contest. For the award-winning project, Eldredge equipped a traditional English fascinator headpiece with Adafruit’s GEMMA platform (ATtiny85) along with an accelerometer to measure a wearer’s movement. Data collected by its embedded sensors prompted a series of NeoPixels within the hat to change color intensity and temperature from blue to green, yellow, orange and red.

As if one piece of headwear was enough for Eldredge, the incredibly innovative Maker has returned. This time with a fantastic fascinator for all holiday festivities!

According to the Maker, her electronic Christmas confection — aptly dubbed the Hot and Cold Christmas Cloche — features a temperature sensor that is responsible for triggering its lights to change colors depending on whether it is hot or cold. Ideally, the FLORA powered (ATtiny85) wearable will emit icy blue when it’s outside and a holiday spirited red and green when it’s inside, or anytime its environment is above 60°F. As she points out, the colors will soon intensify the more extreme the temperature.

XmasMockup2

If all goes according to plan, aside from its embedded FLORA, Eldredge assumes the hat will be comprised of the following components:

  • 1.3m white NeoPixel strip
  • 1-3x AAA battery pack
  • 3 through-hole 8mm NeoPixels
  • 2 through-hole 5mm NeoPixels
  • Analog temperature sensor

  • A white wool felt hat

As the Maker notes in her recent Element 14 Community post, she began by connecting the 1.5-meter NeoPixel strip to the ATtiny85 based FLORA and alligator clips, before conducting a NeoPixel strip test. Miraculously, she says, it worked on the first attempt!

“I disconnected those alligator clips from the FLORA and placed one of the 5mm through-hole NeoPixels in my breadboard. I cut and placed small bits of wire to correctly power and connect the LED to the FLORA. Then I found the Punk Collar code and changed the pin number to pin 9 and uploaded it to the FLORA. The light changed color beautifully. Then I placed the remaining four through-hole NeoPixels in the breadboard so that each Data-Out pin was column-buddies with the Data-In pin of the following LED, and used more little pieces of wire to connect each to power and ground. I ran the Neopixel Tiara code again and they worked,” Eldredge writes.

She then went on to connect the temp sensor.

“I disconnected the LEDs at the FLORA end and placed my temperature sensor on the opposite side of the breadboard, using more wires to connect it to the FLORA. Then I uploaded the example Simple Thermometer code and opened the serial port to find that the room was a sweltering 138 degrees fahrenheit. That didn’t seem quite right. So I read over the Temp Sensor overview and realized that it was calibrated to receive 5 volts of electricity and I was only giving it 3.3 volts. I changed the calculation to compensate, re-uploaded the code, re-opened the serial port, and all was well. A perfectly reasonable 70 degrees.”

As she puts the finishing touches to her design, you can find a step-by-step breakdown of the build along with its recently-revealed code here.

Adafruit’s Pro Trinket gets the Hackaday.io treatment

Last year, Adafruit launched the Trinket, a tiny microcontroller board built around our ATtiny85. Then back in August, they shared the news that the uber-mini board was getting a big sister, the Pro Trinket. Based on the incredibly-popular, Maker favorite ATmega328, the Pro Trinket offers the familiarity of an Arduino Pro Mini with more pins and USB thrown in the mix.

Today, paying homage to our friends at Hackaday, the Adafruit crew has even unveiled an Hackaday.io branded Pro Trinket — black solder mask, Jolly Wrencher and all. And, it’s stunning.

As Hackaday points out, the board features a micro-USB plug on one end, integrated voltage regulator, 16MHz crystal oscillator, and the chip is running a modified version of V-USB (meaning that it can be programmed via USB). With the Pro Trinket, Makers have the choice of either programming with the Arduino IDE, using AVRdude with the “-c usbtiny” programmer flag, or flashing the chip directly with an AVR programmer like the AVR Dragon.

Don’t let its size fool you. The super small Pro Trinket boasts more flash and more RAM — 18 GPIO, a pair of extra analog inputs, 28K of flash, and 2K of RAM. While the Pro Trinket may only measure 1.5″ x 0.7″ x 0.2″ (without headers), it possesses the same capabilities as a much larger Arduino Uno.

Aside from the on-board ATmega328P, other key specifications include:

  • 16MHz clock rate, 28K FLASH available
  • USB bootloader with an LED indicator
  • Headers for an FTDI port for reprogramming
  • Micro-USB jack for power and/or USB uploading
  • On-board 5.0V power regulator with 150mA output capability and ultra-low dropout
  • Power with either USB or external output (such as a battery)
  • On-board green power LED and red pin #13 LED
  • Reset button for entering the bootloader or restarting the program.
  • Works with 99% of existing Arduino sketches (anything that doesn’t use more than 28K, and doesn’t require pins #2 and #7)
  • Mounting holes

According to our pals over at Hackaday, “This is also perfect for taking with you on the road. The board is so small you’ll always have space for it. I already travel with an external battery and a micro-USB cable for topping off my cellphone. These will work perfectly as a power source and programming cable for the Trinket Pro. The board itself and any hardware I want to hang off of it is all that I’m adding to my backpack. Above you can see the quick proof-of-concept I made while at the Hackaday anniversary party. It’s a row of 8 LEDs and some current-limiting resistors. Want to try your hand with PWM and visualization? You can do it on a plane, you can do it on a train, or a bus, or a boat (Trinket prototyping while bicycling is not recommended).”

Adafruit teardown of Moto 360 reveals maXTouch inside

In what may have been the most highly-anticipated Android Wear smartwatch to date, the Moto 360 is equipped with a bold round face, heart rate monitor, and comes in both black and grey metal finishes. During a recent teardown from the Adafruit crew, Limor Fried even referred to it as a “jam-packed watch [that’s] kind of intense. [They] basically crammed a phone into a watch.”

microcomputers_moto-360-teardown-adafruit-07

Upon dissecting the device, Fried reveals an MXT112S capacitive controller embedded within the watch, thereby confirming that the device is indeed powered by Atmel. “This is not a TI chip, this is from Atmel. Reason why they didn’t go with a TI chip is because TI doesn’t have a chip that does this,” she adds.

microcomputers_moto-360-teardown-adafruit-19-1

The wearable boasts a 1.56-inch, 320×290 display with a backlit LCD touchscreen. The Moto 360’s body comes in at a diameter of 46mm and height of 11.5mm, while the leather band model weighs 49g – essentially, the same weight as your everyday wristwatch. Enhancing its durability, the attractive display is protected by a Gorilla Glass 3 covering.

microcomputers_moto-360-teardown-adafruit-17

Like all Android Wear devices, the Moto 360 features a wake-on-wrist-flick and automatic voice response via the “Ok Google” trigger, which allows a wearer to send texts, set reminders and such. It is compatible with any Android phone or tablet running Android 4.3 or higher, and has IP67 water resistance with submersion of up to 1 meter for 30 minutes. What this means: Shower, good. Swimming, not so much.

The Moto 360′s 320mAh battery should get you about a day of mixed usage. Additionally, the smartwatch comes with a pretty standard 4GB of internal storage and 512MB of RAM, in addition to the vibration motor included for notifications. Like other smartwatches, the Motorola accessory can be connected to your mobile device using Bluetooth 4.0 Low Energy.

Tank Girl goes cyberpunk this Halloween

Whether or not you’re a fan of the 1995 American sci-fi flick Tank Girl, you will surely appreciate this 3D-printed, LED-embedded Bandolier of Light design from Adafruit’s Becky Stern. Just in time for Halloween festivities, this cyberpunk ensemble will surely be the life light of the party!

led_strips_bandolier-of-light

The build is relatively easy, comprised of a meter-long strip of 60 white Adafruit NeoPixels, some wire and sewing supplies, and most importantly, an ATtiny85 based Trinket or GEMMA microcontroller.

led_strips_becky-stern-cyber-tank-girl

The bandolier itself is 3D-printed in white NinjaFlex, enabling it to be comfortable and flexible enough for easy flinging across the shoulder in Rambo-like fashion. After soldering some wires from the NeoPixel strip to the Atmel based MCU, the lights are placed between what Stern calls the “3D-printed bullets of pure love” and a strip of fabric.

Designing a DeLorean-inspired time circuit clock with ATmega32u4

“If my calculations are correct, when this baby hits 88 miles per hour… you’re gonna see some serious shh….”

lcds___displays_Compared

While the DeLorean may have been the most iconic part of Back to the Future’s time-traveling machine, we can’t forget the flux capacitor, Mr. Fusion and of course, the future time circuit display, that made it all possible.

Paying homage to the cult classic, Maker Phil Burgess recently recreated the futuristic clock along with an accompanying tutorial on Adafruit so any movie fanatic could bring their favorite ‘80s movie prop to life. Though the creator admits that he doesn’t own a DeLorean, or any car for that matter, using it as desk or Halloween decor should work just as well.

lcds___displays_Origami

The base of the clock is comprised of a set of LED displays in a metal-painted, laser-cut acrylic housing, controlled by an ultra-slim Teensy dev board (ATmega32u4).

The Power Suit is an Arduino-powered costume

Just in time for Halloween, a Maker by the name of Michael Teeuw has created a slick costume entitled The Power Suit. Though the ATmega168 MCU powered suit originated as just a fun idea to win a theme night competition with a couple of friends, the end result was actually quite stunning!

tumblr_inline_ndpgh9u1Am1s95p1z-2

“Every once in a while you are looking for a nonsense reason to build something completely useless but absolutely awesome. This year’s trip to the Belgian Ardennes is the number one reason to achieve my childhood dream,” Teeuw prefaced.

tumblr_inline_napd4lwAtE1s95p1z

The Maker aspired to create a suit which was equipped with built-in sound effects and voiceover, full-color LEDs, real-time audio and manually controlled lighting, independently powered wings, Bluetooth connectivity, and to round out the Tony Stark getup, a mobile app to act as his J.A.R.V.I.S.

tumblr_inline_nbutl894bw1s95p1z-1

Based on a set of football shoulder pads and chest protector, the Iron Man-inspired suit was brought to life using an Arduino Pro Mini to serve as the brains of the system, a Bluetooth Low Energy shield to enable wireless communication, a series of Adafruit NeoPixels to add the visual effects, a spectrum analyzer to transform audio into usable data for the Arduino, and a step-down power converter to run the electronics.

tumblr_inline_ndpgilcPz61s95p1z

Using the shoulder pads as its base, Teeuw added a pair of ATmega168 controlled servos under each of its flaps to create wings capable of lifting themselves up.

tumblr_inline_nb32vc6mxH1s95p1z-1

The Maker then attained 72 Adafruit NeoPixels. The center of the suit was fitted with a 24 pixel ring and two-8 pixel strips along the shoulders, while another two-16 pixel rings were situated around the eyes using Adafruit’s Kaleidoscope Eyes tutorial.

tumblr_inline_nbg23spQs41s95p1z-1

In order to enhance its next-gen appearance, Teeuw used a 300 million megawatt speaker connected to a 18 watt amplifier.

tumblr_inline_nc7pk3h0gg1s95p1z

Additionally, in order to control the lighting effects, color and wings, the Maker tasked a Nintendo Wii nunchuck connected to the Arduino.

Rounding out Teeuw’s must-have function list was the suit’s coinciding iPhone app. Besides a futuristic designed interface, the iPhone app has five features:

  • Playing looping background sounds
  • Playing speech sounds with a manual or random trigger
  • Playing sound effects with a manual or random trigger
  • Playing speech sounds based on Bluetooth feedback from the suit
  • Feedback about the current actions and connectivity in a console

Oh, and for those wondering as to whether or not Teeuw won the competition, you bethcha!

Halloween-spiration for some paw-some costumes

Makers, rejoice! One of our favorite holidays is quickly approaching — a celebration full of carving, candy consumption, and of course, DIY costumery. Though, we can adorn our own bodies with tricked-out costumes, what about our furry four-legged friends? These two Atmel powered costumes from Adafruit should provide some Halloween-spiration!

Adafruit’s Becky Stern recently demonstrated how to transform a pair of Doggles into cyberpunk-style glasses with a rotating laser. The Maker figured out that with children and sugar-loaded revelers abundant on Halloween, lighting up a ground-level pooch was a favorable idea. Using a Trinket 3v MCU (ATtiny85), a set of clear dog goggles and a laser diode as the center of the device, this invention will surely be a hit on the scene.

trinket_becky-stern-laser-dog-goggles-tank-girl

A small servomotor allows the laser to move back and forth, while playfully recreating the scanning beams of our favorite sci-fi heroes. Intrigued? You can acces the entire tutorial here. (Note: Now, while being the ghastliest ghoul on Halloween is one goal, safety is another of paramount of importance. Before assembling this build for your precious pet, make sure you read through Adafruit’s safety guidelines.)

Whether a fan of the smash hit Doctor Who or not, we’ve got another canine costume that will have partygoers oohing and ahhing this October 31st.

Adafruit has also showed off a TARDIS-inspired sweater that utilizes a FLORA wearable processor and an MP3 music player module to emit the iconic sound from the show’s time machine, while NeoPixels are used for the blinking blue light on top to round out the TV prop. With the ATmega32u4 MCU based wearable platform at the center of the creation, the sweater remains lightweight for even the smallest dogs. Need a few minutes of silence on your trick-or-treat route? An infrared receiver is added to mute the sound when you want quiet.
