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!

Hackaday Prize Entry: Smart USB Hub And IoT Power Meter

[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects, which is an important parameter for dimensioning adequate power supplies and battery packs. Since most SBC projects require a USB hub anyway, he designed a smart, WiFi-enabled 4-port USB hub that is also a power meter – his entry for this year’s Hackaday Prize.

[Aleksejs’s] design is based on the FE1.1s 4-port USB 2.0 hub controller, with two additional ports for charging. Each port features an LT6106 current sensor and a power MOSFET to individually switch devices on and off as required. An Atmega32L monitors the bus voltage and current draw, switches the ports and talks to an ESP8266 module for WiFi connectivity. The supercharged hub also features a display, which lets you read the measured current and power consumption at a glance.

Unlike most cheap hubs out there, [Aleksejs’s] hub has a properly designed power path. If an external power supply is present, an onboard buck converter actively regulates the bus voltage while a power path controller safely disconnects the host’s power line. Although the first prototype is are already up and running, this project is still under heavy development. We’re curious to see the announced updates, which include a 2.2″ touchscreen and a 3D-printable enclosure.

Prototyping a smart bulb with JavaScript, Arduino + PubNub

In this video, our friends at PubNub are going to create a smart home network that builds upon their previous Johnny Five tutorial. They again hack an Arduino Uno using JavaScript, but this time to create the simplest smart bulb. Because by “smart bulb,” we really just mean an LED.

The tutorial was developed by Tomomi Imura from PubNub and also uses Johnny-Five. No, not the robot from the movie Short Circuit. It is an open-source JavaScript robotics framework that lets you program an Arduino with Node.js. The bulb itself is remotely controlled via a web portal.

To establish the realtime communication between the Arduino and a web browser, the PubNub Data Stream Network (DSN) is used. PubNub provides global infrastructure and allows you to build and scale real-time apps and IoT devices quite easily.

The remote controller (web app) is written in JavaScript. This is a simple user interface that includes only one button. While a completed code sample is available on CodePen, this tutorial employs a simplified version so that it’s easier to follow along.

Massimo Banzi explores the meaning of the IoT

Back at Arduino Day 2016, Massimo Banzi explored the true meaning of the Internet of Things in a more philosophical, approachable way. During his presentation, the Arduino co-founder touched upon the current state of the industry, some guiding principles, as well as what the future may entail.

“A lot of people are trying to build products that are connected, but not a lot of stuff makes a lot of sense right now. There’s a lot of strange stuff happening. It’s the beginning of an industry,” Banzi explained. “There’s a couple of misconceptions. A lot of people tend to equate the Internet of Things with smart thermostats for your home, and it’s much more than that. The part of the IoT that right now is impacting and can impact your life the most is the least sexy one.”

Bring IoT features to Arduino boards with the Yún Shield!

Great news for Makers working on IoT projects! The Arduino and Genuino Yún Shield — now available on our online store for $49.90/€43.90 — is a device that enables you to easily bring Yún features to Arduino and Genuino boards supporting shields.

It’s the perfect shield to start connecting your projects to the Internet thanks to the Yún Web Panel and the dedicated ”YunFirstConfig” sketch. This new feature, implemented in the new Arduino Software (IDE) 1.6.9, allows you to manage your shield preferences and upload your sketch on the attached Arduino or Genuino. Like the previous Yún board, the Yún Shield uses the Bridge library and extends your board capabilities using the Linux processor.

The new Yún family runs the latest version of OpenWRT (15.05 Chaos Calmer), which offers an additional layer of security and a large amount of bug fixes over previous Yún distribution. The precompiled package list is huge (we have more than 4,000 packages ready to be installed), and if you still can’t find what you are looking for, you can use the community provided repositories since the new release is fully modular (not a fork).

Not Even Hamsters Are Safe From The Internet Of Things

The internet of things is this strange marketing buzzword that seems to escape from the aether and infect our toasters and refrigerators. Now even a hamster is not safe.

[Mifulapirus]’s hamster, Ham, was living a pleasant hamster life. Then his owner heard about another hamster named Sushi, whose running wheel stats were broadcasted to the internet. Not to be left behind, Ham’s wheel was soon upgraded. Now Ham is burdened by the same social pressures our exercise apps try to encourage us to use. No, we are most certainly not going to tell our friends about two fourteen minute miles with a twenty minute coffee break in the middle, MapMyRun, we are not.

The feat of techno enslavement for the little hamster was accomplished with a custom board, an esp8266, and an arduino as described in the instructable. The arduino can be left out of the project now that the libraries have been ported to the esp8266. A hall effect sensor detects when the 3D printed hamster wheel is spinning.

If you’d like to check in on Ham, the little guy is alive and well, and the twitter is here. It looks like it’s been upgraded since the original article was posted. Now it shows when Ham is awake and running around the cage doing hamster errands.
