Lift takes finger tracking accuracy to a new level

Using a pair of Arduino MKR1000s, researchers at the University of California, Irvine and FX Palo Alto Laboratory have come up with a new way to track 10 fingers to within less than two millimeters.

In this technique, called “Lift,” a normal DLP projector is used to display a series of tiny encoded images onto any flat surface. Instead of using an external vision system, or even an accelerometer, Lift employs tiny light sensors on each finger to detect this pattern, then relay this information to the MKR1000 mounted on each wrist. From there, the Arduino is able to translate these light signals into positional data with an average accuracy of 1.7 millimeters and an average refresh rate of 84Hz.

By projecting encoded visible patterns onto an object’s surface (e.g. paper, display, or table), and localizing the user’s fingers with light sensors, Lift offers users a richer interactive space than the device’s existing interfaces. Additionally, everyday objects can be augmented by attaching sensor units onto their surface to accept multi-touch gesture input.

Harry Potter fans create a fully-functioning smart wand

In the Harry Potter series, a Muggle is a person who lacks any sort of magical ability. Growing up reading these books, one can only imagine what it would be like to cast spells using a wand. Well, wonder no more as a group of NYC Muggles decided to build their own smart wand that can ‘magically’ control devices over Wi-Fi.

The 3D-printed wand is equipped with a voice recognition module that lets users cast spells of their own with a flick of the wrist, like ordering takeout from delivery.com, turning the lights on and off, as well as playing and silencing music.

Other components include (what appears to be) a MKR1000 board, a LiPo battery, a PowerBoost, a microphone, a switch, and a vibrating motor that indicates when a command is recognized.

Those wishing to buy one are out of luck, as the creators reveal this was merely a fan-made project to celebrate the Harry Potter prequel Fantastic Beasts and Where to Find Them.”  You can read more about the Muggle Wand here! 

Make a WiFi-controlled mini robot using the new MKR2UNO

A few days ago, we launched the MKR2UNO Adapter, which enables you to easily turn an Arduino Uno form factor project into a MKR1000-based one. Simply mount your IoT board to the adapter, plug in any Uno shield and have a wireless device in no time.

Our newly-published tutorial provides a step-by-step overview of how to build a WiFi-controllable robot using the MKR2UNO Adapter with a MKR1000 and an Arduino Motor Shield.

This project combines the Arduino MKR1000’s web server and Arduino Motor Shield’s capabilities to drive a pair of different DC motors. A basic interface is hosted and hard-coded in the MKR1000, allowing the user to maneuver the robot up, down, left or right.

An interactive ball for your dog’s remote entertainment

Recently presented at Disrupt SF Hackathon 2016, this modified hamster ball rolls and dispenses treats while you’re away!

Creators Anthony Alayo, James Xu, and Lawrence Chang don’t like the idea of leaving doggies alone all day to fend for themselves. Although these companions will generally wait for their owners to get home, this surely gets boring. To help solve this problem, they created the DogeBall–a hamster ball equipped with advanced electronics including what looks to be an Arduino MKR1000. This allows it to roll around under remote control via an accompanying app, and can even give your pooch a treat, perhaps as a reward for not chewing up your shoes!

Say you’re at work and your dog has been alone for a while. If you have a nest cam or other home cameras setup, playing with him/her is easy. The app we created acts as a remote controller, connecting to the ball over the internet. Shoot your dog a treat, hit the speak button to talk with him, or control the ball as if you were right there beside him/her.

Sound like something you might want for your pup? You can check out the team’s Devpost article or TechCrunch’s writeup on this excellent project!

Kick off this year’s U.S. presidential race with the MKR1000

No matter which candidate you will be voting for in November, it’s hard not to chuckle a bit when seeing this project from YouTuber “Makers4America.” The IoT machine works by responding to tweets from presumptive Republican candidate Donald Trump and then proceeding to kick him in the face with a 3D-printed boot attached to a metal rod.

The setup is fairly straightforward: a Raspberry Pi running Node-Red and a local Mosquito MQTT broker poll Twitter, and then writes the tweets to an MQTT topic. Meanwhile, an Arduino MKR1000 runs an MQTT client subscribed to the same topic, and controls the servos and RGB LED strips reading “Dump Donald.” 

Although this project targets Trump, it’s hard not to imagine other use cases for such a device–one in which includes the face of your arch nemesis, a rival sports team, or perhaps even your ex. The possibilities are endless!

Add IoT capabilities to an IKEA night light with MKR1000

During a recent workshop, Swedish innovation studio Topp set out to create a platform for rapid prototyping with design and data. The team decided to take an existing product and retrofit it with IoT capabilities. For this, they selected an IKEA Spöka night light and hacked it with an Arduino MKR1000. The connected lamp is capable of reacting to its surrounding environment through sound, motion, and light, while an accompanying app is used to monitor and control intensity.

Traditionally data and physical interactions have been difficult to work with, often requiring the availability of early hardware or by constructing mockup data. However, to achieve quick iterations and a higher fidelity experiences for projects involving data, sensors, cloud, and other things typically unavailable to designers early on in projects, we’ve developed a tool called Noodl to help support a better way of working. We’re using Noodl as a foundational tool when we hack our night light.

A key function for this hack is to have the lamp and the phone connected to an IoT cloud broker. Bluetooth or other non-routable communications would not work with remote presence, so by using Wi-Fi and a public broker we could build a prototype that also works with multiple clients in a true IoT fashion.

The end result was a platform that makes use of cloud and data, which could be employed for a wide range of intelligent home devices ranging from a baby monitor to a morning alarm to a smart dimmer. You can read all about the project — along with instructions, code and components — on Topp’s page here.
