These two parents just built a ‘Mad Max’ Power Wheels


These kids’ Halloween costumes are sooooooo much cooler than yours. 


If you think kids are the only ones that can have a blast on Halloween, you’ve clearly never seen Maker parents Cory and Jeremy Newton-Smith, who’ve become well-known for devising some pretty remarkable costumes throughout the past few years. Most recently, the retrofitted a couple of old Power Wheels Jeeps and transformed them itnto a Mad Max trick-or-treating vehicle for their two children.

The Newton-Smiths, both software engineers by trade and Makers by night, are no strangers to creating elaborate Halloween ensembles. Their past three getups have included Elliot on his bike with E.T., the Ghostbusters complete with an Ecto-1, and Marty McFly with a time-traveling DeLorean. And this year, they pulled out all the stops once again by dressing up their four-year-old son as Mad Max and their 11-month old daughter as Imperator Furiosa.

The Power Wheels-based War Rig replica boasts four motors, a smooth starting throttle, power steering, keyed ignition, sounds effects with pull cord truck air-horn and LEDs embedded into the dash, as well as the ability for 11-month-old Furiosa to drive via an overriding remote-controlled iPhone app that communicates with the car over Bluetooth Low Energy. Aside from all that, a heartbeat signal was also added to remote override mode to ensure the car stops when losing connection or goes out of range, which is probably best when you’ve got young ones behind the wheel!

Connecting a paper notepad to the Internet of Things


This notepad and pencil use conductive ink to control a Think With Google app.


London-based branding agency MultiAdaptor has designed a paper notepad and pencil that employs conductive ink to control an app for Google’s digital marketing business. The goal of the project was to raise awareness of Think With Google in the creative community by inspiring them to engage with the service’s content in unique fashion. And what better way to do this than by plugging a piece of paper into the Internet?

03_TheExperience_3

In order to make the notepad, industrial designer Roland Ellis developed a special (and quite possibly the world’s first) conductive bookbinding glue that connects an Arduino-compatible board (which appears to be an ATmega32U4 based MaKey MaKey) to printed pages without having to use cables or any other parts. Conductive ink was screen-printed onto the paper, which is activated using a standard graphite pencil.

“The digital experience is also designed to reflect the Google brand — something simple and helpful, but playful and innovative, too,” the MultiAdaptor crew explains. “The audience is time-poor, so we made it faster to discover what’s relevant to them, by creating a bespoke ‘edit’ of content with a few ticks or clicks.”

02_TheIdea_4.1

To get started, users plug the notepad into their desktop via a provided USB cable, visit the Think With Google website and check off two options from a list of statements using the pencil, such as “increase brand awareness” or “drive sales.” The interface focuses primarily on four different types of content: deck-ready stats, thought-leading articles, Google business tools and inspiring video content. From there, a user selects the platform that they want to leverage, which includes search, video, mobile and display. Content matching their selection is then shown in a dashboard titled My Edit. From there, users can share a link to their edit or virtually ‘rip’ off a page from the pad and create a new one. Aside from that, the dashboard can be accessed independently and the presentation-friendly interface can be employed in an office environments or at an event.

So far, 1,000 notepads have been printed, assembled and in the process of being shipped to agencies throughout the UK and Italy. Intrigued? Head over to the project’s official page, or watch its overview video below.

Maker dad creates an El Niño Halloween costume with lightning and rain effects


Another Halloween, another incredible Glowy Zoey costume! 


We’re not sure what we get more excited about every Halloween: the endless supply of candy or GlowyZoey’s costumes which have become an annual tradition in the Hutain household. Royce Hutain, the Maker dad behind digital LED suit projects like last year’s Minnie Mouse stick figure getup, has done it again. This time, he has pulled out all the stops to create a slick cloud costume, complete with special lightning and rain effects.

GR2KwA7 - Imgur

Inspired by El Niño (the band of warm ocean water that develops in the central and east-central equatorial Pacific), Zoey’s outfit consists of 98 LEDs and an Arduino Nano (ATmega328) to control the lightning. There’s also a hidden, handheld switch that triggers a rain system above her head, comprised of a washer fluid pump that sucks water up from a bottle in her backpack.

The cloud hat “turned out to be a little bit too big for her little neck to support and her head wobbled a bit,” Hutain explains. “But she loves making the rain turn on.” As cool as the project may be, Zoey has decided she wants to go as Elsa for Halloween this year instead. LOL! You can see it in action below!

LINKKI is a DIY kinetic construction kit


LINKKI lets you design movements whether it be for kinetic prototyping or storytelling.


The brainchild of Eun Young Park as a part of her at Master’s thesis at Aalto University School of Arts, Design and Architecture, LINKKI is a DIY toy kit based on a planar linkage mechanism that enables Makers and designers to prototype their own simple movements, create kinetic storyboards, as well as learn basic STEM principles through hands-on tinkering.

1duehksByyqTlREPTt8ZrBg

The idea for the DIY kit first came about after having been inspired to extend storytelling media beyond two-dimensional space and into the physical world with interactive components.

“Consisting of a modular box, bars and circles, and active modules, LINKKI simplifies the technical construction toy to such an extent as to look minimal but still retains the versatility of construction blocks as an educational tool and designer’s prototyping tool,” Park explains.

1Wdo3g1Wn-Aik4-8zWi-OHg

Devised with expandability in mind, LINKKI allows for Makers to add various modules to any project. For example, a signal meter or visualizer can be built on top of the kit, and when coupled with a sensor (like a weather or push sensor), can trigger interesting behaviors. Aside from that, this lets users familiarize themselves with the concept of physical computing and the Internet of Things.

eunyoung-park-linkki-modular-toy-designboom-10-818x611

Made from birch plywood, PLA and metal, there are 16 types of bars in four different shapes and two circles. Movement is driven by either a hand crank or one of three types of Arduino-based motor boxes: a full rotation version that spins with a constant speed when a user pushes a button, a limited rotation device that revolves to and fro between the angles set by a knob, and an interactive motor that moves according to the Wi-Fi signal sent from the sensor unit.

Making a wearable toothbrush machine with MeArm


Punch Through Design’s Simone Giertz has created a helmet that brushes your teeth. 


With seemingly everything around us becoming smarter, it was only a matter of time before your toothbrush became Internet-connected as well. Equipped with sensors, these accessories are now capable of detecting improper brushing habits, analyzing the healthiness of your teeth and ensuring that you’ve spent enough time cleaning. Despite how intelligent they’ve become, they still lack one major convenience factor: hands-free control. Perhaps that may all change after companies lay their eyes upon Simone Giertz’s latest creation.

Nrs

The San Francisco-based Maker and Creative Technologist at Punch Through Design has developed a prototype of what she calls the Toothbrush Machine a clever combination of both a skateboard helmet and a MeArm. Whereas most MeArms are equipped with a claw, she replaced it with a toothbrush instead.

The system, which we covered on Bits & Pieces earlier this year, is powered by an Arduino Uno (ATmega328) along with a servo shield and motor. As you can see from the GIF below, the Tim “The Tool Man” Taylor-like contraption features a robotic arm that drops down and precisely paces the bristles in front of the wearer’s teeth, as it begins scrubbing back and forth.

FS1RX2JICOXDAM2.MEDIUM

For those unfamiliar with the MeArm, the Arduino-compatible device is the brainchild of Benjamin Gray and Jack Howard, and was designed to be a simple and affordable way to put robotic arms into the reach of Makers. Essentially a shrunken-down version of ordinary industrial machines, the portable mechanism opens the doors to countless projects — clearly demonstrated by Giertz.

According to the Maker, the helmet was devised as part of a pilot episode for a kids TV show with hopes of teaching viewers about electronics by building more or less “useless robots.” It also serves as a great reminder that you don’t always have to take your projects too seriously. Regardless of how silly it may look, however, such an innovation could one day help those with impaired mobility regain their independence while providing tremendous oral hygiene benefits.

FYKLKHSICOXDAPI.MEDIUM

While you may not see your dentist or the ADA endorsing a product like this anytime soon, it’ll certainly be a conversation starter to say the least! And now, you can create one of your own by following Giertz’s step-by-step tutorial on Instructables.

Better yet, maybe MAKE: Magazine is onto something: why not take it step further and add a few extra arms for a Q-tips ear cleaner, a brush makeup applicator and a Gillette beard shaver.

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.

FarmBot is the world’s first open source CNC farming machine


FarmBot is an open source CNC farming machine and software package designed for small-scale precision food production.


A finalist in this year’s Hackaday Prize, FarmBot is a perfect example of how the DIY Movement can make a long and ever-lasting impact on our world. The brainchild of Rory Aronson, the project is an open source CNC farming machine that hopes to make an open food future more accessible to everyone.

2733541437238396942

Essentially, FarmBot is like a giant 3D printer that, but instead of extruding plastic, uses seeds and water to grow crops. Similar to 3D printers and CNC mills, FarmBot hardware employs linear guides in the X, Y, and Z directions, which allows for tooling such as seed injectors, watering nozzles, sensors, and weed removal equipment to be precisely positioned.

Not unlike many RepRap printers available today, FarmBot is controlled by the Arduino Mega (ATmega2560)/RAMPS stack, along with an Internet-connected Raspberry Pi 2, NEMA 17 motors and rotary encoders. The open source device can cultivate a variety of crops all in same area at the same time, and can impressively care for each one in an optimized, automated manner.

According to Aronson, the outdoor XYZ unit can be constructed to fit each owner’s individual needs. It can scale from a garden as small as one square meter to as large as a farm that’s 20 square meters. In terms of cost, the Maker estimates a FarmBot to run anywhere from $1,500 to $4,000, depending on the size of the installation. And since it’s comprised of corrosion-resistant aluminum, stainlees steel and 3D-printed plastic components, it’ll withstand Mother Nature for years.

20150113_140302

Using the web-based app, a user can graphically design their farm or garden to their desired specifications and then synchronize the numerical control code with its embedded hardware. With its sequence builder and scheduler, FarmBot combines the most basic operations in custom sequences for seeding and watering, and even enables you to build complete regimens for the plant throughout its lifetime.

What’s more, a drag-and-drop interface lets users graphically design the plant layout in a game-like environment similar to FarmVille. Aside from that, additional features of its software include storing and manipulating data maps, accessing an open plant data repository, and real-time control and logging. Moreover, an integrated decision support system can automatically adjust water, fertilizer and pesticide regimens, as well as handle seed spacing and timing based on soil and weather conditions, sensor data, location and the time of year.

6776631445215008659

Looking ahead, the team is experimenting with sensors, drills and a camera tool, and more importantly, hopes to expand its community of hackers and DIY food enthusiasts interested in developing the platform. FarmBot will come in two different kits, Genesis and Genesis XL, 1.5 meters by 3 meters and 3 meters by 6 meters, respectively. The latter will be capable of growing four times the amount of food as its smaller sibling. Both models can be used outdoors, inside a greenhouse or even on a rooftop.

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.

tumblr_mvjpstNsMi1qbsnxwo4_500

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.

Amino lets you grow living cells to create interesting things


Biology class is about to get a lot more fun! Amino reduces the size and complex nature of large lab equipment into a countertop-sized system.


When it comes to the Maker Movement, things like 3D printers, milling machines, laser engravers and soldering stations are pretty common on workbenches and countertops. A desktop biolab? Not so much. However, this is something a group that began in MIT’s Media Lab is hoping to change.

lryunacwytbadwp2wgrs

The brainchild of Julie Legault, Amino is an Atmel powered bioengineering system that enables anyone to grow and take care of living cells — whether at home, at school or in a Makerspace. Inspired by Tamagotchis, the all-in-one mini-lab allows you to perform the genetic transformation of an organism’s DNA through guided interactions, resulting in a synthetic organism that can be cared for like a pet.

The ultimate goal is to bring the necessary tools for bioengineering to the masses, ones in which have been traditionally quite expensive and only available in research labs. Now, Amino is bundling those instruments into a small, desktop-friendly package that makes it accessible to transform living cells into things like fragrances, flavors, materials and medicine. Plus, it will automatically capture multiple sources of data in real-time, letting you learn more about how your cells are developing and what needs to be done to ensure proper growth.

Synbio-Amino-tamagotchi_MIT-Media-Lab_dezeen_936_6

Amino itself is a sophisticated piece of Arduino-driven hardware with circulation and temperature controls for its user, as well as sensors that can keep tabs on how fast your microbes are growing and how much food they’re eating. Housed in a square wooden box with a hinged plastic lid, Amino contains everything required for users to undertake their own synthetic biology experiments. It includes modular chambers, which can be swapped out for a new microbe food and nutrients, pH balancing solutions and even other chemicals that help control your DNA program. What’s more, the system boasts a touchscreen that displays the real-time instructions along with indicator lights that walk you through the creation process.

“Synthetic biology and wetware is poised to be the dominant technology of this century, the way electrical engineering was for this last century. It allows scientist to problem-solve food, energy, health and materials in sustainable new ways. By bringing the science out of the labs with the Amino, we are enabling everyone to take part in their own future by creating and problem-solving at home and in the DIY labs. Amino gives you a chance to experience this impactful technology, hands on,” Legault explains.

gp5lqqs0ablnt8yv7e6k

Right now, the Amino kit is optimized for use with a friendly, non-dangerous type of bacteria generally used in labs for research. This strain, which arrives in a test tube, is rated BSL1 (lowest biosafety level 1) by the Center for Disease Control. In other words, it’s non-pathogenic and doesn’t require special containment equipment. Ideally, Amino aims to lessen the fear and complexity from basic interactions with bioengineering. It empowers Makers and students alike to experience synthetic biology, all while discovering an important and complex topic in an intuitive way.

“At Amino, we think of DNA programs like an Android or iPhone ‘apps’ for living cells. But even more, keeping living cells alive outside of their normal environment requires other growth liquids, like food, and chemicals. Amino apps are a combination of the DNA programs and the growth liquids,” Legault adds.

a9ri0feoqd2jeo3jizbz

For starters, you’ll be able to employ Amino to grow your own living nightlight by combining the harmless strain of E. coli with synthetic firefly DNA. Legault hopes to introduce new kits that would eventually enable Makers to develop their own yeast for baking, bacteria for yogurt, or more importantly, explore a variety of DNA programs such as optimizing the pathway for violacein production, an expensive anti-cancer research agent. Just think: What if many millions of people from around the world could help solve cancer, instead of a small number of scientists?

To make this all possible, the former MIT Media Lab team is partnering with Synbiota, a company that makes DNA programming as simple as LEGO. By using their technology, Makers will be one day able to devise their own genetic apps and insert them into cells with Amino. Aside from that, Amino will also come with an automated cleaning system. This way, when it’s time to start a new project, simply run a clean cycle, change out the modular chamber and you’re good to go!

Intrigued by this “Arduino-like kit for synthetic biology?” Head over to Amino’s Indiegogo campaign, where Legault and the Amino Labs crew are currently seeking $12,500. Delivery is slated for June 2016.
