Play Tetris on this tiny, Arduboy-powered device


Thanks to this awesome little gadget, you can say goodbye to productivity! 


Tetris is arguably one of, if not, the most popular video games of all-time and has been played on pretty much every platform possible, from the NES to graphing calculators to mobile phones. Now there’s another, and much more productivity killing, way to play the iconic game. Introducing the Tetris MicroCard, a fingertip-friendly device that’s no larger than a business card.

If it looks vaguely familiar, that’s because the aptly name Tetris MicroCard is powered by and shares a resemblance to the wildly popular Arduboy — a wallet-sized 8-bit gaming system for Makers. Once again open source, the tweaked gadget is based on an ATmega32U4 and powered by an internal rechargeable battery that can last for roughly six hours. Like the Arduboy, the Tetris MicroCard features a microUSB port that can be used for refueling as well as for uploading your own open source apps.

Although it comes equipped with an officially licensed version of Tetris, the tiny console is also fully programmable with Arduino — meaning you can add other games if you’d like. The Tetris MicroCard boasts an OLED display with six control buttons positioned on both sides, as well as a speaker with a mute function, which will surely come in handy when playing in a meeting, in your cubicle or even in class.

It should be noted, however, that the vertically-oriented device and its screen were specifically designed for optimal Tetris playing, so some of the codes available may not be ideal for the unit’s unique layout. And unlike with its sibling Arduboy, creator Kevin Bates (who we’ve come to know so well) has decided to bypass Kickstarter altogether and make the Tetris MicroCard available for pre-order. With a price tag of $49, it’ll make for a perfect grab bag item, a stocking stuff, or a “just because” purchase! Delivery is expected to get underway sometime this spring.

Build your own spider-like robot with STEMI


This DIY kit lets kids make their own nature-inspired robot while learning electronics, programming and more. 


What’s better than a bio-inspired, crawling robot? A spider bot that you can build yourself, that’s what. Locomotion mimicking nature has been around for a little while, but up until now has only been available to university researchers. That’s all going to change. In an effort to entice more young Makers to pursue STEM fields, one Croatian startup has developed a DIY smartphone-controlled hexapod.

STEMI

STEMI, a play on the acronym STEM, ships in the form of a DIY kit along with a series of multimedia tutorials that instruct its teenage Makers to piece together their gadget and bring it to life. More than just a robot, however, STEMI is designed to be a learning experience for users ages 13 and up as they explore the basics of 3D modeling, electronics, Arduino and programming. In the near future, they’ll also be able to create their own 3D-printable custom covers, ranging from Batman to a Walking Dead-like zombie.

Although primarily targeted for the younger generation, there’s nothing that says kids at heart can’t get in on the fun as well. STEMI is capable of performing complex movements, adjusting heights, walking in three different way and dancing. The best part? Using a smartphone’s built-in gyroscopic sensor, Makers can completely control the robot’s movement by simply tilting their handheld device.

MG_8892

Making it even cooler is the fact that STEMI is fully open source, meaning anyone can freely modify its code, blueprints, 3D models and more. The robot itself is built around an Arduino Due-compatible (SAM3X8E) board and a custom PCB packed with an Arduino shield, a Bluetooth module, a USB battery charger, voltage regulators and LED indicators. Aside from that, the kit comes with 18 servo motors, a rechargeable battery pack, aluminum body parts, rubber leg caps, as well as various nuts and spacers.

So, are you ready to begin assembling your own spider bot? Then crawl over to its Indiegogo campaign, where the STEMI team is currently seeking $16,000.

Transform your swimming pool into an LED dance floor


This Maker covered his swimming pool with Rainbowduino-powered LEDs to create one heck of a dance floor.  


Like something straight out of Saturday Night Fever, Loren Bufanu has managed to transform his swimming pool into an LED-laden dance floor. And from the looks of its surrounding environment filled with garnished chairs and tables, it would appear to be for a wedding or party of some sort.

IMG_20150430_000222

To accomplish this feat, the Maker covered the pool with several glass panels, each outfitted with LEDs. Inspired by the Lampduino on Instructables, the project required nearly 450 meters of RGB LED strips controlled by two Rainbowduinos (ATmega328), driven by 64 power MOSFETs, 64 transistors, 64 bipolar transistors, a few capacitors and some resistors. Producing white light from the LEDs drew 8A from the power supply.

Although he originally thought to use the Colorduino as embedded in the Lampduino, he was unable to find a way to connect two of the boards together and control them with the same interface. So instead, he turned to a pair of Rainbowduino v3.0, which are pin compatible with the Colorduinos and can communicate over I2C. For those unfamiliar with these boards from Seeed Studio, the Arduino-compatible MCU features two MY9221 chips, which are capable of handling 12 channels of Adaptive Pulse Density Modulation.

In terms of software, the Maker used Pixel Invaders. Unfortunately, this portion of the project didn’t come as easy as the hardware installation. Bufanu had wanted the lights to flash in sync with some tunes, but a few setbacks in program didn’t allow for this to work. In the end, he decided to employ some simple visualization software combined with the Pixel Invaders “Screen Capture” mode. Fortunately, that did the trick.

“Basically, MilkDrop-like software is displaying some colors on the screen, and Pixel Invaders capture the screen, controlling the two Raibowduino after that pattern. Both are started by a simple batch file located on the desktop of the controlling PC. It was a ‘ugly hack’ but it is doing the job great,” Bufanu explains.

Creating the ultimate Arduino-lovers Halloween costume


Happy Halloween Hallowuino!


Two years ago, mechanical engineer and cartoonist Angela Melick (who goes by the nickname Jam) developed a pretty neat Halloween costume based on her favorite prototype development board: the Arduino. And that’s not all. Not only does it look like an Uno, it’s actually powered by one as well.

arduino-board-costume

“It’s hard to tell in the first photo but the outfit is covered in puff-paint traces — all up and down the arms and over the back. It was a lot of work but it looks really cool,” Jam explained in her blog post.

The costume is equipped with a series of LEDs that go down her side and blink to a preprogrammed pattern, handled by an Arduino around her neck. Aside from that, a few glow stocks were used in place of “wires,” which as Maker jokingly notes, “represent the tangled mess that any Arduino project is in its first stages.” And we can’t help but notice the ATmega328 at the heart of this ensemble, which appears to be made of styrofoam.

However, Jam’s favorite part of the entire costume? The matching fascinator which features a second Arduino and a few more flashing lights, of course!

“This was my first time soldering ‘free’ wires and 8/8 of the LEDs worked, which I’m very proud of because the wires go all the way down the side and alllll the way back up the shirt,” the Maker added.

Feeling inspired to go make your own costume? Better hurry up, as we’re just days away from Halloween! In the meantime, you can check out Jam’s entire build here.

Shadowplay is like an Arduino-powered sundial for a wall


This touch-responsive clock tells time with the shadows of your finger.


If you have trouble reading an analog clock, this neat little piece of wall decor may not be for you. That’s because Austrian design studio Breaded Escalope has developed a clock that uses shadows to reveal the time when a finger is placed within its face.

bE-uhr-shadowplay_web

The aptly named Shadowplay Clock is mounted to a wall, and made up of a raised plywood ring with LEDs underneath that shine through. By placing their finger in the middle of the circle, a user activates a series of sensors that turn off all but three of the lights. These sensors are connected to an Arduino, which is responsible for relaying the signal.

bE-uhr-shadowplay_both_web

Each LED casts a shadow of the outstretched arm, similar to a sundial, in the directions that the clock hands would normally point to at any given time. The hour and minute shadows appear darker, while the seconds “hand” is represented by a much fainter silhouette.

Meet the world’s first DIY origami robot


With Kamigami, engineering is for everyone. Build your own bug bot and then control it with your phone. 


STEM education has been a growing venture in schools across the country, with even the President himself making it a priority to encourage students as young as grade-school to pursue the science, technology, engineering and math disciplines. After all, these fields are changing the world rapidly within the areas of innovation, economic growth and employment. But let’s face it; these subjects don’t come easy to everyone, so how do we instill STEM in kids? A team of UC Berkeley graduates found a way to pique children’s interests, while also inspiring the next generation of Makers. Meet Kamigami, an origami-style robot you can build and program by yourself — no engineering degree necessary.

60679f270120b57627ec82434801dd5a_original

Kamigami is the brainchild of Dash Robotics, a startup founded by Berkeley engineers Nick Kohut and Andrew Gillies. The company firmly believes in STEM education, and that the power of innovating is for everyone. Kamigami was created with this belief in notion, and it has proven to be an educational and affordable way for kids to get an early start in robotics, engineerin and biology.

Now live on Kickstarter, these robots come in a DIY kit comprised of laser-cut body components, a motor, a transmission, a rechargeable battery, a microUSB port, and plug-and-play electronics. The assembly takes less than an hour and instructional videos online shows you how it comes together. Plus, the robot’s behavior can be programmed and controlled all through Kamigami’s accompanying mobile app (for iOS and Android).

54663bb696ee300eece363d5b05ab410_original

Each Kamigami can be configured with a unique set of behaviors and characteristics through a drag-and-drop interface, opening up a range of possible modes that take advantage of the robot’s integrated sensors and functions. So what type of games is it capable of? For starters, sumo wrestling (first to fall of a table loses), relay races (one robot can’t run until it’s tagged by another), tank battles (take turns trying to get into firing position) and IR laser tag, to name just a few.

And unlike other DIY robotic kits before it, biology comes into play in the automation of each Kamigami. In fact, the bots take into account animals and mimics their locomotion through its built-in linkages and motors. The robot’s chassis is made of a patent-pending material (an extremely durable plastic composite) that allows it to fold up through an origami-like process. This material doesn’t fatigue or wear, which makes for a more durable robot.

840388299b7a9c99d259ebc54f0b87de_original

The mechanics of the robot itself are custom designed, and packed with processing power and sensors. The main microprocessor features a Cortex-M0 core and a Bluetooth Smart radio. Plus, the cockroach-ish unit is packed with an array of sensors including ambient light, infrared detectors and emitter, a gyroscope and an accelerometer. The electronics also entail motor drivers, charging circuitry and an accessory header for expandability. The infrared emitter and detectors enable each bot to send and receive signals from its mobile app, as well as communicate with other Kamigamis. The gadget runs on a rechargeable battery, with about 30-45 minutes of play time.

Sound like a bug bot you’d love to have? Crawl over to its Kickstarter campaign, where Dash Robotics is currently seeking $50,000. Delivery is expected to get underway in March 2016.

This robotic arm writes the time on a Magna Doodle


Clock a Doodle doo!


Ah, the good ol’ Magna Doodle. For kids, it’s a neat toy. For parents, it’s a chalkboard without the mess. For Makers, well, it’s an innovative canvas to keep track of their day.

The idea to devise a mechanism that can write the time in pen or marker isn’t all that new. Not only isn’t it innovative, it is only a temporary solution as pens run out of ink and markers dry up. Inspired by a dry-erase doodling clock that he built a few years ago as a joke, Ekaggrat Kalsi decided to do something a little different. The Maker had found his previous gadget to be so mesmerizing that he wanted to transform it into a practical, everyday desk accessory.

6394021443951640433

For this, the mechanism needed to be a bit more reliable, aesthetically pleasing, and of course, accurate. This got him to thinking: Why not use a magnetic drawing board that could perpetually jot down the hours and minutes?

Based on an ATmega644P, the Maker’s new time-writing machine consists of a Magna Doodle display, a robotic arm controlled by a pair of 1:100 geared 15mm stepper motors, and two solenoids with cylindrical magnets on the end of the arm. The motors are handled by a standard StepStick, while the coils are driven by an L293DD Dual H-Bridge. It should also be noted that the project’s kinematics was solved with the help a fellow user on the RepRap forum.

Before arriving at his latest product, Kalsi devised two prototypes. The first one employed a motor on the base and another motor mounted to the arm, which drove the upper arm by a thin cable. The end result wasn’t as precise as he’d like. For the second iteration, the Maker swapped out the cable for a connecting rod, as the cable kept slipping. Still not perfect. And now, there’s this… See it in action below!

Go Back to the Future with these Maker projects


“The future isn’t written. It can be changed. Anyone can MAKE their future whatever they want it to be.” — Doc Brown


Unfortunately, not all of us are lucky enough to have a time-warping DeLorean that’ll let us travel into the future at warp speed. After watching Back to the Future II, it’s safe to assume that we’ve all been waiting 30 years for October 21, 2015 to finally come — also known as the day that Marty arrives! What better way to pay homage to the ingenuity of Doc — who happens to be a Maker himself — than by compiling a list of our favorite BttF-inspired projects?

2015? You mean we’re in the future?

lcds___displays_Finished

For anyone who grew up in the ‘80s, this display panel should look incredibly familiar. It’s the time circuit, which Doc built into his 88 mph DeLoren machine. The brainchild of Phillip Burgess, the clock consists of LED displays housed inside a metal-painted acrylic enclosure, controlled a Teesny 2.0 (ATmega32U4) that was able to fit in places that an Arduino couldn’t.

It’s a bird! It’s a plane! It’s a DeLorean drone!

DeLorean-Drone_3

Back in 2011, YouTuber Native118 decided to honor the cult classic by modding his quadcopter into a DeLorean drone. While it may not have been able to fly through time, it could however fly through the sky… and in style. Its stainless steel body was replaced with lightweight foamcore, and equipped with LED headlights and taillights. Although it even had a mini Mr. Fusion on its back, power was supplied through a LiPo battery. Aside from that, he employed a MultiWii for stabilization, a HobbyKing 12A BlueSeries speed controller and a batch of Turnigy 2204-14T motors for the engines.

Time circuit’s on! Flux capacitor, fluxing!

fphiq1phxsus31s-medium

Just one of the many BttF props that Chris Fry hopes to replicate someday, the Maker recently devised a remote-controlled flux capacitor based on the Arduino Uno (ATmega328). The gadget features several audio tracks and lighting effects with varying modes (e.g. disco and reverse) at different speeds.

Roads? Where we’re going we don’t need roads!

With a love for the DeLorean DMC-12, one pair of Canadian Makers spent more than 600 hours creating a retro-chic BttF golf cart, which boasts speakers that emit phrases from the movie along with a capacitor controlled by an Adafruit Pro Trinket (ATmega328).

Playing the BttF theme with floppies

maxresdefault

How do you honor the nostalgic tunes of BttF? Think McFly, think! With floppy music, of course! This is exactly what YouTuber Arganalth did. He attached a Raspberry Pi to a bunch of floppy and HDD drives, housed the entire system inside a suitcase and then programmed the drives’ mechanisms to play the famous songs. He employed a PC that sent the data to an Arduino Uno (ATmega328), plus integrated some batteries for power and portability.

When this baby hits 88mph, you’re gonna see some serious…

Led

In the parking lot at the mall, Doc uses a remote control to drive around his time-traveling car after putting his dog (Einstein) in the driver’s seat. Resembling the original Futaba FP-T8SGA-P, Maker Todd Jones designed a mock controller with an LED counter running an Arduino, along with a sound module that’s typically found inside singing birthday cards. With a flick of a few switches, the device turns on and the display begins to count upwards to the DeLorean’s necessary 88 mph while emitting the character’s legendary phrases.

Size adjusting – fit… Drying mode on. Jacket drying.

F7RU0V6IFUEFZWB.MEDIUM

With a desire to make Marty McFly’s auto-adjusting jacket a reality, the Instructables crew took it upon themselves to take a glimpse into what a future with self-sizing garments would look like. The team of Makers developed jacket sleeves that start off too long and then go up as if they modify itself to the correct length. This was accomplished by using a 3D-printed pulley mechanism and micro gear motors. Whenever a button on the jacket hem is pushed, cables are wound around a pulley, drawing the sleeves up. These cables are threaded through a simple tube system built inside the jacket and sleeves.

Power laces, alright!

rsz_1img_9127-1024x682-2

Aside from the DeLorean and hoverboard, there’s one other notable thing from BttF that has left us eagerly waiting to get our hands on feet in for decades. If your recall, Marty throws on a pair of Nike high-top sneakers that automatically lace and tighten by themselves. Tired of having to wait until 2015, Maker Hunter Scott chose to do his part and help make such footwear a reality with the help of Arduino Pro Mini (ATmega328) and a few other widely available components. A force sensitive resistor taped beneath the heel of the insole lets the Arduino know when a wearer steps into the shoe, while a rotary encoder on the motor shaft ensures that all the power lace cycles are the same.

Maker builds his own self-lacing sneakers


Footwear that’s just in time for Back to the Future Day! 


Aside from a time-travelling DeLorean DMC-12 and hoverboard, there’s one other notable design from Back To The Future II that has left us eagerly waiting to get our hands on feet in for years. During the cult classic, Marty McFly puts on a pair of Nike high-top sneakers that automatically lace and tighten on their own. With October 21, 2015 finally upon us, Maker Hunter Scott decided to do his part and help make such footwear a reality.

rsz_1img_9127-1024x682

Impressively, Scott didn’t even need Dr. Emmett Brown’s help to bring this idea to life. Instead, he ordered himself a pair of knockoff Nike Air Mag sneakers and gathered several widely available parts, including an Arduino Pro Mini (ATmega328), a LiPo battery, a USB charger, a motor, a motor driver, a shaft coupler and a rotary encoder. He also incorporated a switch to turn the kicks on/off and a button to activate the system.

The BttF-inspired shoes came with removable strap which Scott ended up removing part of its velcro, allowing it to slide without catching. The Maker carved out a notch in the back to install the motor, shaft coupler and encoder, and used a little bit of fishing line to go around the top, providing the power behind the laces.

rsz_img_9126-1024x682

A force sensitive resistor taped beneath the heel of the insole lets the Arduino know when a wearer steps into the shoe, while a rotary encoder on the motor shaft ensures that all the power lace cycles are the same.

Admittedly, the DIY sneaks are not exactly likes the ones worn on the big screen. For one, they don’t loosen automatically — you’ll have to hit the button for that. Secondly, Scott points out that they pale in comparison to the speed of McFly’s kicks… for now anyway. Regardless, they’re pretty darn cool if you ask us! Intrigued?

PupPod is a smart dog toy that trains and entertains


Man’s best friend is smart. His toys, not so much… until now. 


For dog owners, do you ever wonder what your pup does when you’re away? Or maybe you do know because you’ve had the experience of coming home to destroyed furniture, garbage strewn on the floor, and… an anxious dog. This destructive behavior has been attributed to separation anxiety in dogs, so what can you do to keep your best friend from feeling lonely? Canine owner and software designer Erick Eidus has a solution.

0314e9fd24107bd5e1c072d80f94edfa_original

Meet PupPod, an interactive, self-learning pet toy that helps reduce boredom, anxiety and destructive behavior in dogs, while also helping them learn new skills when you’re out for the day. Eidus had conceived the idea after he started thinking of games from a dog’s perspective and how pet parents could better understand their pet, check in on them and even interact with them when at work. He brought this idea to an Arduino meet-up, and it materialized in just 48 hours. After testing over 250 dogs across five prototypes, the Maker and his team are now ready to make PupPod available to a community of pilot users.

88e1469603f4fac9dcfdf1304df84b39_original

PupPod is a smart platform that is wirelessly connected to a treat dispenser, video camera and an accompanying mobile app. The unit offers a new use of the operant conditioning method by having your dog play multi-level games and earn treat rewards. You can stream live video, make decisions in the game, trigger treats remotely and record videos. You can also review your dog’s progress, monitor and set limits to treat/food rewards, as well as understand what they’re learning all through your own doggy dashboard. Aside from that, the gives you access to a growing PupPod community and a leaderboard so you can compare your four-legged companion to your friends or other dogs of similar age and breed.

f316ee8ab9ca0b9935841e5f16ef6523_original-1

Built around the LightBlue Bean (ATmega328P), the PupPod is comprised of three components: an incredibly tough and durable Kong Wobbler to house the toy; a PupPod Hub which includes a 720p HD camera, Bluetooth integration and a RaspberryPi B+ to send data and video to the PupCloud; and a treat dispenser. The platform employs a motion sensor to detect when your dog comes near and emits sounds from an internal speaker to get your dog’s attention. The toy communicates with the PupPod Hub over Wi-Fi and uses an accelerometer to sense motion when it’s touched.

Eidus and his team have just wrapped up a successful Kickstarter campaign, and hope to get the first batch of toys out come February. Interested in one of your own? Check out PupPod’s official page here.
