[Marcus Olsson] of slickstreamer made a battery-powered temperature logger using ThingSpeak to store and visualize the data collected. He chose the Electric Imp Wi-Fi module for connectivity. The project is complete with a 3D printed case.
All of the source code to connect Electric Imp to ThingSpeak and the 3D printer design files are available on Marcus’ blog ‘slickstreamer‘.

[C.A.V.A.] created a cigar humidor with a social life. A humidor stores cigars in a humidity controlled environment to maintain freshness, but this special humidor sends the humidity sensor value to ThingSpeak and alerts Twitter when you need to add water. The project uses a humidity sensor and an Arduino Ethernet to post the data to the ThingSpeak API.

C.A.V.A. has more info about the project, parts list, and photos on his website.
In 2013, ThingSpeak was used in 158 countries and territories. The vast majority of the traffic came from countries in North America, Europe, Australia, and South America. ThingSpeak is growing quickly around the world!

We have developed a new ThingSpeak App and it is available now to all ThingSpeak Users.
The new TalkBack App allows devices to check ThingSpeak for commands to execute. TalkBack is perfect for battery-powered devices that need to sleep most of the time and wake up to see if there is anything to do and then go back to sleep, like a door lock for example. The lock is mostly going to be asleep to save battery power, but it can wake up periodically and check TalkBack or be woken up by a button press to see if it should be opened or not.
Devices powered by ThingSpeak and now with TalkBack will be able to both push sensor data to the ThingSpeak Cloud and check TalkBack if any commands are available all in one request. To get started, we have the complete TalkBack API Documentation and an Arduino Yún Tutorial available now.
Atmel-powered Arduino Yún Tutorial
With the release of TalkBack, we created a tutorial for the Arduino Yún. The “Yún” is a special combination of easy-to-program Arduino with an additional processor, an Atheros AR9331, running Linux and the OpenWrt wireless stack. Programming the Arduino via USB is identical to the Arduino Leonardo. Once the Arduino Yún is connected to Wi-Fi, the Arduino has full access to ThingSpeak Cloud Services and the TalkBack App and API. Check out the Controlling the Arduino Yún with TalkBack tutorial for a step-by-step way of controlling the Arduino Yún via TalkBack and the ThingSpeak Cloud.
TalkBack is available now to all ThingSpeak Users and to new users by Sign Up for Free at ThingSpeak.com! Please feel free to share with us and the ThingSpeak Community with the awesome ways you use TalkBack with your ThingSpeak Projects!
[Andrew Bythell] created a ThingSpeak Java Client for the complete ThingSpeak API. This Java Client makes it really easy for Java (or Processing) developers to add cloud connectivity to applications and non-networked devices. “The purpose of the ThingSpeak Java client is to enable non-networked Device-to-ThingSpeak gateways and other applications for performing advanced analysis of data feeds,” said Andrew.
So, by using Java, a simple “Hello World” app becomes this easy…
Channel channel = new Channel(channelNumber, apiWriteKey);
Entry entry = new Entry();
entry.setField(1, "Hello World");
All of the source code and documentation are available on GitHub. Get started right away with building your Internet of Things with the Java Programming Language and the ThingSpeak Cloud.
Excellent work Andrew – thanks for contributing to the Open Source ThingSpeak Community!

ThingSpeak is growing quickly these days. Our traffic is high and the user growth is soaring. Thanks to everyone for your interest and patience as we continue to stabilize, add more servers, and add more features to help with your Internet of Things projects.
Question: How do I find ‘public’ ThingSpeak Channels?
In order to help developers find open data inside of ThingSpeak Channels, we created a new API for searching the public ThingSpeak Channels.
Here are the Public ThingSpeak Channels. We order the channels by activity and completeness. Channels may be tagged and this helps find data that you might find interesting for your application. We also have API commands that you can pass to the ThingSpeak Channel API to return the public ThingSpeak Channels in either JSON or XML format.
Here are some easy examples:

For the third holiday season in a row, the CheerLights project is gearing up. The idea behind CheerLights is to show that we are all connected by synchronizing the color of lights around the world. Christmas lights are a staple around the holidays and with Internet-connected lights, the color of your lights matches the color of everyone else’s lights.
It has been a real treat watching this project evolve as more and more people add lights… and other things. Things like Android and iPhone apps that check the latest color of CheerLights, Christmas trees, and robots.
To control the lights around the world, send a Tweet mentioning @CheerLights and a color. The command is processed by ioBridge’s ThingSpeak platform and distributed to all of the lights listening to the CheerLights API.
@CheerLights I am dreaming of a White Christmas
Internet of Things
Another powerful aspect of the CheerLights project is that is shows off what is possible with the emerging Internet of Things. With a single message sent via a social network like Twitter, 1000′s of objects around the world are in sync with each other. Lights are connected by many types of controllers, such as Arduino, ioBridge, Philips, and the Raspberry Pi. This project is only possible through the Internet and the coordination of developers around the world.
In the article, “How the Internet of Things Will Change Our Lives“, CheerLights is included to indicate how we are connected and how objects may bring people closer.
Learn how to join the project at CheerLights.com.
We are all connected…

Dexter Industries launched a very successful Kickstarter campaign this past summer to build and release the BrickPi. The BrickPi turns the Raspberry Pi computer into a robotics and sensing platform for LEGO® MINDSTORMS®. Since the wrap up of the campaign, users have jumped on board making cool projects using the BrickPi including a step-by-step tutorial using ThingSpeak to store, share, and visualize sensor data.
Check out the tutorial, “ThingSpeak Temperature with Raspberry Pi“, to learn how to send sensor data using the BrickPi, a Raspberry Pi computer, and a temperature sensor for the LEGO® MINDSTORMS® NXT. The project uses ThingSpeak to store, share, and visualize sensor data collected by BrickPi-enabled projects. The Python code for the Raspberry Pi is available on GitHub and the entire project is open source!

[Marcus Olsson] from Slickstreamer created a solar-powered temperature logger using the Electric Imp Wi-Fi module to push data up to ThingSpeak to store and visualize the data collected by his sensors. Marcus provides a parts list and a how-to on his blog. The temperature sensor, solar panel, and solar charger are all readily available parts from Adafruit.
Looking over the code for the Electric Imp, it looks pretty easy to cross-clouds from the Imp to ThingSpeak. Check out the source code on GitHub and full details on Slickstreamer.
The Open Hardware Summit is September 6th, 2013 at MIT’s Kresge Auditorium in Cambridge, MA. For the third year, ThingSpeak is sponsoring the event!
The OHS is an amazing experience. You get to meet all the Open Source Hardware heroes that are pushing this movement forward. This year there are many talks and panels covering all aspects of the open source hardware movement. Our part in all this is to push open platforms to connect all that open hardware. ThingSpeak is growing very quickly supporting the open hardware and software for advancement of the Open Source Internet of Things.
Sponsorship opportunities are still available!
