Pro Trinket powers this brilliant bike POV display

Light up your nighttime bike ride with this persistence of vision display from Adafruit.

In the past couple of weeks, we’ve seen numerous Maker projects focused around bicycles. To recount just a few, there’s been a smart helmet with turn signals and automatic brake lights, a smartphone-controlled handlebar lighting system, and most recently added to the list of bright ideas (no pun intended), Adafruit’s persistence of vision (POV) for your wheels.


The brainchild of Becky Stern, this POV display allows riders to illuminate the night as they pedal their way along the road or sidewalk. As the tires rotate, a series of embedded lights flash, ultimately conjuring up an image in the viewers’ minds. The project is comprised of two DotStar LED strips attached to a wheel spoke — one facing in each direction — driven by a 5V Pro Trinket (ATmega328) and powered by a 3xAA battery pack affixed near its hub.

To get started, Stern cut a half-meter strip of LEDs, leaving 36 pixels on both halves. She then tinned the solder pads and silicone coated wires to the input end of the freshly cut piece, alternating sides for each wire to help prevent a short circuit.


“If you have a 5V Pro Trinket to spare, we strongly encourage you to build a prototype of your circuit on a solderless breadboard. Not only will you get a chance to test out your solder joints connecting the LED strips, but you can have a duplicate system for programming where you can easily make changes,” she advises.

In terms of coding, the POV uses the same program as Phillip Burgess’ Genesis Poi project. Adafruit not only lays out the installation process on their page, but has made the sketches for the bike wheel available on GitHub. The bike POV requires the Adafruit DotStar library for Arduino as well.


From there, Stern trimmed off the header pins, and tinned the wires attached to the LED strips. These four wires are soldered to the Pro Trinket. After testing the circuit, it’s imperative to waterproof it before sticking it onto the bike. Those wishing to save power can also employ an optional switch and/or vibration sensor, which will only trigger the lights when in motion.

How do the electronic stay on, you ask? As challenging as it may be, the battery pack is anchored near the hub by steel zip ties, while plastic zip ties keep the LED strip and Pro Trinket tightly onto the spokes of the wheel.

Pretty cool, right? Head over to Adafruit’s official step-by-step tutorial, and watch Stern’s latest work in action below!

Create your own cardboard armor with programmable lights

Crafteeo combines art with the magic of technology to create a fun learning experience for children. 

One look around any Maker Faire would reveal that DIYers love cosplay. With this in mind, one San Diego startup has developed an innovative way to inspire future generations to build things with their hands while exploring the technological world around them. How, you ask? By transforming themselves into heroes with their own armor and then programming its LED lighting.


“Kids love playing with cardboard boxes. This is well know fact that seem to be universal across different cultures and generations. If there’s any cardboard in the house, kids will inevitably grab it and start crafting something,” entreprenuer and Maker dad How-Lun Chen explains.

The idea behind Crafteeo was first conceived after Chen and his wife decided to do all of their holiday shopping online back in 2011, which of course, left them with mountain of boxes on Christmas morning. Upon opening his gifts, rather than play with his shiny new toys and RC cars, they watched their son exercise his imagination using nothing more than the pieces of cardboard spread across the floor. Then it hit him: What if there was a way to recycle these materials into something cool, like a helmet, shield and sword, all while teaching children to learn electronics?

And so, Crafteeo was launched. Currently live on Kickstarter, each kit comes with some pre-cut cardboard, D-rings, faux leather cords, pieces of plastic, water-based paint in metallic colors, and a series of solder-free, Arduino-compatible hardware. The Pulsar Helmet and Armor are built around an ATmega32U4, powered by three AAA batteries and ships with jumper wires, header pins, a proto board and a photoresistor module.


“To increase the versatility of the kit, we selected a powerful Arduino-compatible microcontroller that can be adapted to a variety of projects beyond glowing a LED light. Additionally none of the components are permanently connected together. We envision that down the road we will add additional capabilities to the helmet and armor either as upgrade kits or as free online tutorials. More importantly we want your kids to reuse or repurpose the electronics,” Chen adds.

What’s nice about the project is that it can grow with the Makers themselves. Meaning, as the child gains confidence and hones their programming skills, the Pulsar kit includes different lesson modules for each step of the way. For instance, the earliest stage — geared towards ages eight and up — doesn’t require any programming and provides users with an overview of basic electronics, as well as an introduction to microcontrollers and LEDs. Once completed, a second level walks them through the process of changing pre-set variables to customize LED lights. And finally, a young DIYer will ultimately be able to discover how to program from scratch using the Arduino IDE.


The armor, helmet and shield are comprised of double-layered cardboard which makes them quite durable. The sword, in particular, is stiff and much like those made of soft woods like pine. Digital patterns for both the helmet and shield are emailed in PDF format to those just starting out, along with a set of step-by-step video instructions. And to keep in line with its mystique and to help spark the child’s imagination, Crafteeo has created its own magical storyline around the “World of the Guardians,” the fantasy world’s equivalent of the Coast Guard.

“When kids put this on, their persona completely changes. You see their former self just kind of melt away, and they become this heroic self,” Chen explains.

Interested in a Pulsar helmet and armor for your child? Head over to its Kickstarter page, where Crafteeo is currently seeking $10,000. Delivery of units is expected to get underway in November 2015.

MotorMood is looking to make the road a happier and more social place

Now you can say thanks to other drivers at night using a remote-controlled, light-up happy face.

Living in places like Los Angeles and the Bay Area certainly have their perks, however they’re also notorious for extremely long and congested commutes. Born out of their own frustration with hostile traffic jams and miscommunication that often occurs between drivers, one Southern California-based startup has developed a way to make rush hour a bit friendlier. After all, if our roads and their potholes are becoming increasingly more social, shouldn’t our cars as well?


And so, MotorMood was born. By affixing the accessory to a rear window, users can easily say thanks to other drivers at night through a remote-controlled, light-up happy face. Sure that may not seem like much, but how often have you tried waving to a fellow driver to express your gratitude for letting you pass or make your way into the morning gridlock, only to wonder if they ever saw it? Fortunately, this can take out the guesswork.

The emoticon illuminates for six seconds through a remote control button that clips onto a sun visor, just like a garage door opener, and requires very little, if any, concentration to operate. What’s more, drivers can select from one of three colors to start: blue, pink, or green. There is also a red face overlay certain jurisdictions which require all rear-facing lights to be red.


The device, which measures 4.8″ in diameter, has been optimized for nighttime use, meaning that it’s vibrant enough to be seen from afar without distracting others. The face calls for a set of four AA batteries while the remote uses one coin cell, with a life of around six months.

“MotorMood uses a proprietary light guide display to create a beautiful, high quality image on the road. Three specifically placed LEDs fire light into a substrate with tiny divots, which distribute the light across the product’s surface for an evenly lit appearance. The brightness has been carefully optimized for nighttime use so that it’s bright and vibrant, but does not interfere with visibility or safety,” its creators explain.


So why a smiley face, you may ask? Research has proven that simply staring at the happy emoticon for five seconds can actually make someone feel happier than they were before.

However, as rudimentary as a light-up ‘thank you’ may sound, MotorMood is hoping to expand upon its array of emojis with themed collections and even licensed characters. Despite requests, the company says that it will never produce middle fingers or angry faces. (Sorry, New Yorkers!)


Yet, what really excites its team is the possibility of Bluetooth connectivity that would pair with a “Kindle-like display that could serve as a status bar for your car.” Looking ahead, the team tells Entrepreneur that future iterations may be configured to track the number of smiles given or received per day via an accompanying mobile app, as well as do things like recognize the kind of music playing on the radio that will then show that information like a real-time bumper sticker.

Sound like something you’d love to have in your car window? Apparently you’re not alone, as its Kickstarter campaign is well on its way to garnering its pledge goal of $150,000.

Lumioto is an easy-to-use, open source LED prototyping tool

Lumioto makes it easy to add expressive, professional LED effects to prototypes, design models and videos.

It seems like these days, just about every product on the market contains at least one LED. The same goes for DIY projects. Sure, LED designs are great. However, if you’ve ever tried to configure them, you know just how tricky it can get. Even the earliest steps like controlling brightness and choosing colors can present a few unexpected challenges, not to mention adding animation only seems to make matters worse. Cognizant of the limited number of tools available, SCALAR Electronics has developed Lumioto, a quick and simple way to go about the LED creation process.


Based on an Arduino Uno (ATmega328), Lumioto gives users the ability to make fine modifications on up to three independent RGB LEDs, including toggling their brightness, color and pattern. The open source tool is equipped with an intuitive hue-saturation-lightness (HSL) on-board color picker, along with 14 different built-in animations with adjustable speed, intensity and relative timing. This way, designers and Makers alike can easily add LED effects to prototypes, models and a wide range of other projects.


What’s more, users can experiment with 24-bit digital color and brightness by plugging into any USB port. If that port happens to be on a computer, they can configure more advanced settings using Lumioto Terminal, ranging from turning LEDs on/off and getting readouts to adjusting settings and accessing flexible LED animations. Whether for professional or amateur use, the possibilities are truly endless. Given that it’s Arduino-compatible, Makers can even hack its code and add their own new features and functions.


Other notable specs include:

  • Full set of three 36″ Lumioto LED cables included (2X inline, 1X angled)
  • High brightness: Up to 3000mcd per LED (1200mcd with white-balancing enabled)
  • Hex color reference and digital brightness readouts
  • Detachable LED cables for easy modification, permanent LED integration, or multiple simultaneous projects
  • All settings saved automatically for convenience and mobility
  • Identical Mac and Windows support; no drivers required
  • USB-powered
  • Open source firmware
  • Completely free firmware development toolchain (Atmel Studio + AVRdude, Windows-only)
  • Entire Arduino port D0-D7 accessible for hardware expansion
  • ~50% CPU, RAM, FLASH utilization


“Don’t know Arduino? That’s okay. With the Designer Kit, you don’t need to be into electronics to use Lumioto. It’s the same as the Maker kit, except it comes with an Arduino preprogrammed with the freshest Lumioto firmware. It’s ready for action right out of the box, down to the included USB cable,” its team writes.

Interested in adding professional LED effects to your next design? Following a successful Kickstarter campaign, Lumioto is now selling both on Tindie and its official site for $89.00.

OSM is an AVR-based, open-source LED microlight

OSM is an easy-to-use, open-source, reprogrammable microlight with endless possibilities. 

Created by Pasadena, California startup Quantum HEX, OSM is an open-source microlight ideal for various wearable projects. Built around a versatile ATmega328P, the OSM is packed with with a micro-USB port, a three-axis accelerometer with custom features, several I/O connectors, a WS2812 addressable LED strip, as well as unmatched sensitivity.


The microlight is ready for use right out of the box and comes pre-loaded with 10 modes including many old-school favorites like BPM heartbeat, rainbow chaser and 3D morph. What’s more, its creator Ramiro Montes De Oca reveals that Makers can continually update their light on the fly with some basic coding.

“Once you save a setup you can save it as a file and send it to all your friends — they just need to copy and paste it onto their chip. We’re building a developer community so that you can learn (as well as trade) from one another. Our code will be posted up for free, and you’ll be able to post up your own code as well,” De Oca explains.


The OSM (no accelerometer) and the OSM-xyz (with accelerometer) are not your typical microlights. Unlike others available today, users can easily employ the USB port to upload new programs — meaning, there’s never a need to go buy new lights.  Boasting incredible speed capacity and memory, a Maker can burn up to five different lights on one OSM, as each head has its own color palette, presets and modes. This makes it a clear choice for wearable projects, like gloves, which require illuminations on each finger.


Being 100% reprogrammable OSM, a user simply connects the microlight to a computer (Mac, Linux or Windows) via a OSM Programmer, which serves as its interface. The OSM Programmer is a redesign of the popular Arduino2Serial adapter, connecting the reset line to the USB shield.

“Using the micro-USB shield to set low the reset input makes the Micro-USB an alternative communication option to serial communication with an external serial programmer,” De Oca adds. “This is a serial adapter modified to plug into a micro-USB programmer. A USB-to-serial adapter can be plugged on the communication ports of the OSM as alternative.”


Programs can be downloaded from its website and then uploaded directly to any OSM in its original format with Arduino IDE. Given the open-source nature of its NEO 1.0 application, a Maker can modify and expand every aspect of the program in copy and paste-like fashion. What’s nice is that, as soon as a user is done with one OSM, they upload the same code to each of the others.

Sounds like a bright idea, right? Head over to it official Kickstarter page, where the De Oca and the rest of the Quantum HEX team are currently seeking $25,000. Shipment is expected to start in July 2015.

12 projects that are redefining storytelling

In honor of World Book Day, here are some Maker innovations that are redefining storytelling…

They say stories can come to life, and well, these projects have taken that saying to an entirely new level.

This isn’t your typical coffee table book


Jonathan Zufi’s coffee table book entitled “ICONIC: A Photographic Tribute to Apple Innovation is the ultimate must-have for any Apple aficionado. The hardcover recounts the past 30 years of Apple design, exploring some of the most visually appealing and significant products ever created by the Cupertino-based company. The commemorative piece features a special white clamshell case along with a custom PCB configured to pulse embedded LEDs — like that of a sleeping older generation Apple notebook when moved — controlled by an Atmel 8-bit AVR RISC-based MCU.

This magical device will add augmented reality to storybooks 


The brainchild of Disney Research, HideOut explores how mobile projectors can enable new forms of interaction with digital content projected on everyday objects such as books, walls, game boards, tables, and many others. The smartphone-sized device enables seamless interaction between the digital and physical world using specially formulated infrared-absorbing markers – hidden from the human eye, but visible to a camera embedded in a compact mobile projection device. Digital imagery directly augments and responds to the physical objects it is projected on, such as an animated character interacting with printed graphics in a storybook.

This interactive piece of art tells a narrative


Created by Fabio Lattanzi Antinori, Dataflags is a narrative series of artwork that explores the financial troubles of corporations as they head towards bankruptcy, while highlighting the pivotal role data plays in today’s society. The piece — which was originally displayed in London’s Victoria & Albert Museum back in September 2014 — was powered by Bare Conductive’s incredibly-popular Touch Board (ATmega32U4) and some Electric Paint. The printed sensors were concealed by a layer of black ink, and when touched, triggered a selection of financial trading data theatrically sung by an opera performer.

This book judges you with its cover


Have you ever judged a book by its cover? Well, Amsterdam creative studio Moore is turning the tables on the old-school idiom by designing a sleeve equipped with an integrated camera and facial-recognition technology that scans the face of whoever comes near. The idea behind the aptly named Cover That Judges You was to build a book cover that is human and approachable-hi-tech. If someone conveys too much emotion – whether overexcitement or under-enthusiasm — the book will remain locked. However, if their expression is free of judgement, the system will send an audio-pulse to an Arduino Uno (ATmega328) and the book will unlock itself. The built-in camera is positioned at the top of the book’s sleeve, above a screen that feeds back the image when it detects a face in close proximity. Artwork featuring abstract facial features is displayed on the cover so that the user can line up their eyes, nose and mouth in the optimum position. Once the correct alignment is obtained, the screen turns green and a signal is relayed to the Arduino that opens the metal lock.

This interactive book lets you feel characters’ emotions


A team of MIT students unveiled a wearable book that uses networked sensors and actuators to create a sort of cyberpunk-like Neverending Story, blurring the line between the bodies of a reader and protagonist. The sensory fiction project — which built around James Tiptree’s “The Girl Who Was Plugged In” – was designed by Felix Heibeck, Alexis Hope, Julie Legault and Sophia Brueckner in the context of MIT’s Science Fiction To Science Fabrication class. The “augmented book” portrays the scenery and sets the mood, while its companion vest enables the reader to experience the protagonist’s physiological emotions unlike ever before. The wearable — controlled by an [Atmel based] Arduino board — swells, contracts, vibrates, heats up or cools down as the pages of the book are turned. Aside from 150 programmable LEDs to create ambient light based on changing setting and mood, the book/wearable support a number of outputs, including sound, a personal heating device to change skin temperature, vibration to influence heart rate, and a compression system to convey tightness or loosening through pressurized airbags.

This storytelling tree reads with you


In an effort to bring more interaction to story time, Northwood’s Childrens Museum in Wisconsin created a storytelling tree capable of reading along with you. The old computers inside the the museum display were retrofitted with a Touch Board (ATmega32U4) from Bare Conductive. In fact, this was a welcomed replacement as one staff member said that the computers “broke constantly and hogged power, keeping us from updating sounds files periodically throughout the year.”  Unlike its embedded predecessor, the MCU allowed sound files to be changed in an expedited manner, and was slim enough to nestle neatly into the trunk’s design. And what would a treehouse-like exhibit be without a makeshift walkie talkie comprised of cans strung together? Creatively, a set of headphones were also placed inside the can to make it exciting for participants to listen to the story.

This book blends the analog and digital worlds


Makers Israel Diaz and Ingrid Ocana were on a mission to find new ways to bring children closer to the vast universe of reading. In doing so, the duo figured out a new way to enhance a traditional book with basic electronic components and some Arduino Uno (ATmega328) programming to interact with user intervention through simple built-in sensors, AC motors, LEDs and speakers.

This tale is told with the turn of a music box handle


Night Sun is an interactive audiovisual installation which tells a story with the turn of a music box handle, powered by an ATmega32U4 MCU. In order to bring his idea to fruition, the Maker commissioned an Arduino Micro to control the exhibit. The Arduino was instructed to send a ‘play’ command to a computer when it sensed the touch of a passerby. Once the wired music box handle was turned, the window would light up. A pre-recorded sound would then send a signal to the computer and begin playing… and just like that, the story unfolds.

This pop-up book is made for the digital age 


A Maker by the name of Antonella Nonnis recently devised a unique interactive electronic book powered by two ATmega168 based boards. The book, titled “Music, Math, Art and Science,” was inspired by the work of Munari, Montessori and Antonella’s very own mother. The book contains movable parts and uses the electrical capacitance of the human body to activate sounds and lights and other sensors like a button for the math page. Comprised of recycled materials, the book is powered by a pair of Arduino Diecimila, which control the paper pop-up piano and the other controls the arts and science page.

These soft puppets are recreating fables for kids and parents


Footprints – which was prototyped using an Arduino Uno (ATmega328) – can best be described as a network of interactive soft puppets that help create and share illustrated stories. Designed by Simone Capano, the project links various aspects of a child’s life, including school and family, by collecting and storing relevant data in the cloud. Footprints is typically initiated by a parent. Using a smartphone, the parent can record a little vocal story, add some images proposed by Footprints about the story that was just told, like the story’s characters or other objects related to it. Afterwards, the parent can send it all to the child’s puppet. The child can then listen to the story by placing the puppet on the tablet and playing with the images he or she has received to create a drawing about the story. Once the drawing is complete, Footprints send it back to the parent who then tracks the path of the stories shared with a child via the smartphone app.

This book really sets the scene


Created by Bertrand Lanthiez, Hvísl is described as “an invitation to both a visual and audible journey.” Pre-recorded sounds from Icelandic atmospheres are emitted with the help of electronic sensors hidden in some pages connected to a MaKey MaKey board (ATmega32U4). These effects accompany the reading and the contemplation of pictures from the country’s landscape.

This bookmark makes sure you never miss a part


Tired of having to reread pages in because you forgot which paragraph you left off on? Devised by 7Electrons, the aptly named eBookmark is envisioned to serve as a bridge between analog and digital worlds. The device — which is based on an 8-bit AVR MCU, various Adafruit components, 16 tiny LEDs and a resistive touch strip — allows the reader to save his or her place on the page, and with a switch, also select the left or right page. The top portion of the eBookmark extends for use with larger books.

This fiction machines lets you create your own narrative


Who could forget those ‘Choose Your Own Adventure’ books that became popular in the ‘80s and ‘90s? The series of children’s gamebooks where each story is written from a second-person point of view, with the reader assuming the role of the protagonist and making choices that determine the main character’s actions and the plot’s outcome. Similarly speaking, software developer Jerry Belich has created an interactive arcade machine that works on the same premise. The Choosatron is an interactive fiction machine that lets users select the story, while it prints out a transcript of the chosen story paths. In essence, the machine is a cardboard box with a small thermal printer, a coin acceptor, a keypad, an SD memory card and an Arduino-compatible board.

Throw on a pair of #Ravespecs for your next party

Wondering what to wear for that party? Make yourself some LED glasses.

What do you get when you combine basic safety goggles, an laser-cut acrylic frame, some electronics and plenty of RGB LEDs? One electrifying pair of #Ravespecs, that’s what. Throw ‘em on and you surely become the ‘light’ of any party.


Created by Lorenzo Wood, the glasses were originally a last-minute, thrown-together idea for a friend’s party. Initially conceived as a mask, the Maker felt that glasses would be “a bit more social.” He thought about powering the specs through a remote battery tucked away in his pocket and running wire to the glasses; however, Wood realized that it would be much more fun, portable, and of course, aesthetically-pleasing to make them self-contained.

“In spite of the rushed build and the shoddy wiring, they turned out to be quite robust. The reason that there are wires visible on the front is that for speed I wired the power with just two stripped wires, threading them in and out of the LED strips and connecting them with solder. I don’t recommend that.”

The shades are built around an A-Star 32U4 MCU (ATmega32U4), adorned vertically with Adafruit NeoPixels and powered by standard Lithium AAA batteries mounted to the frame itself. Since the LEDs consume quite a bit of power, a wearer can expect anywhere between one to two hours of continuous use before having to replace its batteries.


Beyond that, a wearer can easily change the lighting sequences or down the brightness with a little coding, and even try to create designs that don’t engage all the pixels at once, such as strobing rainbow, chasing or police-like effects.

“Because of time, I only had one go at the frame design. I positioned the slits around a typical inter-pupillary distance of 55mm-65mm. In fact, pretty much anyone can see through them (even small children), because the frame is held quite a long way from your face by the safety goggles. The slits could therefore probably be sightly narrower so you could get even more LEDs on.”

With the party now behind him, the Maker reveals that he has already begun working on improving the #Ravespecs. Enhancements include more complex patterns, adding radios for synchronizing more than one pair and enabling wireless controlling, as well as incorporating different sensors. The glasses will be able react in more expressive ways through sound, motion and hand gestures.

See them in action below! If you liked this project, then you’ll love these programmable LED shades from Garrett Mace as well!

Creating motion-controlled cabinet lights with ATtiny85

This strip of white LEDs can be turned on, dimmed, and shut off with a wave of your hand.

In Thomas Snow’s house, the kitchen lights never seem to adequately illuminate his counter space. Beyond that, the Maker always seemed to find that whenever he needed to flick on the light switch, his hands were dirty. Cognizant of both of these things, he decided to devise a simple yet clever solution which consisted of installing a motion-controlled LED strip under his cabinets.


As you would imagine, the DIY solution works by simply waving a hand under the cabinet whenever some additional light is required. Snow is able to adjust the brightness by moving his hand up and down within the vertical space between the countertop and cabinet. Think of it as an invisible dimmer switch — or just magic.

This was made possible by employing an ultrasonic range sensor that determines the hand distance between the cabinet and the counter, along with a pyroelectric infrared (PIR) sensor that only activates the ranging when it senses movement around the counter.

“I [didn’t] want to run the sensor all the time because, even though we can’t hear the 40kHz chirp, I imagine the dogs and bird (our pets) can hear it. Additionally, I imagine there is a limited lifetime on the sensor.”

Most importantly, the project is based on an ATtiny85. Snow simply set up an Eclipse environment with the AVR GCC compiler and programmed his own PWM for dimming LEDs)and millisecond counter.

LED wristbands will invade the Academy of Country Music Awards

Throw away your glowsticks and keep your phones in your pocket, because these LED wristbands are headed to the ACM Awards. 

Go to any concert, and during a ballad, look around the crowd. Back in the day, you would be sure to find the flickering of fan’s cigarette lighters filling the night sky throughout the stadium. With the advancements in technology, these lighters were soon replaced by the waving of illuminated smartphones. And well, it wasn’t before long that mobile apps like Virtual Zippo were able to bring the old-school look of lighters right to the device’s screen.


Now, there’s a new innovation in town — one in which you’ve probably already witnessed it in action. Perhaps, you tuned in to this year’s Super Bowl halftime show with Katy Perry? Remember the 516 glowing “orbs” that floated about the field, all wirelessly controlled to create a variety of LED designs? Or, maybe for the younger crowd, have you attended an Ariana Grande tour recently? You may have adorned your heads with the musician’s signature cat ears with a few extra twinkles to amplify the show experience.

Once again, Glow Motion Technologies will be front and center in the national spotlight. That’s because, during the upcoming Academy of County Music Awards, fans will be adorning LED bands to their wrists as they wave their arms along to the tunes of their favorite singers. The devices provided to spectators will ultimately transform the audience into one giant, lit-up canvas, all while increasing sponsor visibility and fan interaction in millions of homes.

The wristbands — a collaboration between Glow Motion, Warner Music Nashville, Mobaglo and Mary Kay — will create synchronized effects from more than 16 million LED color options inside AT&T Stadium during performances from names like Jason Aldean, Garth Brooks, Luke Bryan, Kenny Chesney, Lady Antebellum, among many others.


The interactive wristbands are comprised of silicone, powered by a single AAA battery, and are fully-controllable through its wireless transceiver, enabling them to communicate with one or many thousands wristbands simultaneously. In fact, up to 65,000 devices can be accessed individually using only 33 DMX channels. Beyond that, GMT’s wristbands features the ability to ‘talk’ with each other via RFID. This gives designers and event producers, like the ACM Awards, a whole new way to approach event design and credentialing.

Zedcon is a smart, multi-functional LED controller

This controller illuminates dynamic digital LEDs based on time, music, events and a person’s feelings.

Recently launched on Indiegogo by Berlin-based statup Zedfy, Zedcon is an Internet-enabled, multi-purpose LED controller that allows users to control various LED strips right from their smartphone.


Zedcon comes with a companion mobile app that enables users to dim, switch and play with over 16 million different color combinations offered by RGB LEDs. And if you’re the type of person who rather use a standard light switch, you can as well.

“Common LED strips can light up in every color of the rainbow — but only one color at a time. This is the principal difference to our digital LED strips, where every single LED can be lit up with its own color, while leaving the others unaffected. Zedcon takes full advantage of digital LED strips, by letting you address every single LED on an individual basis. This functionality is important for creating nuanced atmospheres and dynamic light conditions,” the team writes.


The controller lets users set an individual timer for every occasion such as gradually waking you up in the morning or slowly dimming the dining room as you enjoy a romantic dinner, illuminate LED patterns to the beat of music, receive light notifications as a reminder for upcoming event or a completed washing machine cycle, or even adjust to the right setting to fit a particular mood whether that’s trying to get work done or relax after a long week.

Each Zedcon is equipped with a Wi-Fi 802.11 b/g/n module, a built-in microphone, a music-processing chip and an LED indicator, among several other components. Not only is its data stored in the cloud, but each multiple devices can also be connected to a network and controlled either simultaneously or separately.


So, whether it’s automating lighting conditions at various times throughout the day, setting a mood in the office to boost productivity or putting on an impressive light show at your next party, Zedcon wants to change the way you interact with LEDs. Interested in a controller of your own?
