Open Source Thermostat

Smart Thermostat from Spark Core

Many people hailed Google’s $3.2 billion acquisition of connected thermostat maker Nest earlier this month as proof of the immense importance and value of the Internet of Things. But the team at WiFi chip maker Spark, while praising Nest as “the first company to figure out what the ‘Internet of Things’ means to consumers and deliver products that people actually want,” took the announcement as something of a challenge. Using their own Spark Core and some off-the-shelf components, they built a prototype of a Nest-like smart thermostat in just a few hours.

The point wasn’t to one-up Nest or to devalue the work that went into designing that company’s signature product. Rather, Spark wanted to show how easy it is to develop IoT products today, as a demonstration of how far the industry has come since Nest was founded in 2010.

“Nest had to spend millions of dollars on R&D to build the basic infrastructure behind the product,” the Spark team wrote in a blog post documenting their attempt to replicate Nest’s work in a single day.

It’s a striking contrast. All Spark had to do was clip a few sensors and other components to a breadboard, use a CNC mill and laser cutter to carve out a wood and acrylic housing, and spend a few hours coding the firmware. Other functions, like the ability to control the thermostat from a smartphone or provide a learning algorithm so it adjusts to usage patterns, were provided by the Spark Cloud service communicating with the prototype over wifi via a REST API.

Spark spent only $70 to replicate the basic functions of the Nest — but they readily admit that, as a rough prototype, their version is nowhere near as polished.

“In this process, we’ve come to respect the incredible technical challenges that Nest has solved while also coming to understand how much the game has changed since they first started,” Spark wrote.

The recent proliferation of cloud services, APIs, and small chips that integrate processors with wireless connectivity has made it relatively trivial for even low-budget tinkerers to develop powerful, innovative products. Nest’s partnership with Google undoubtedly places it at the top of the Internet of Things ladder — but there’s clearly a lot of room at the bottom, and Spark’s experiment proves just how easy it is to grab a handhold and start hoisting yourself up.

Open Source Bluetooth scale

Open Source Bluetooth scale

Jorge Pinto (Casainho) decided he wanted to lose some weight. For some additional motivation he enabled himself to track his progress over time online using an Android phone, a cheap bathroom scale (20€) and by adding Bluetooth connectivity to the scale.


The project is created using ($75 Estimate):

Originally Jorge utilized two OpenSource Android programs for logging the weight data (Weight Chart and Droid Weight) but has since created his own app on the market for the system called Smart Weight Chart.

He is sharing the firmware, software and pictures of the project on his github account: and is actively looking for other developers to help him create a fully Open Source wireless scale system.

The complete project write-up and history can be found here.

Visualight: open-source Wi-Fi enabled light bulb

What if you could visualize data as colored light, and blend this functionality into your everday life? With some unfortunate timing being released after the blow up press for LIFX comes an open-source and functional WiFi lightbulb alternative from creator Leif Percifield called the Visualight.

Some of you might be familiar with Leif’s work as the creator of the social water quality monitoring project for the New York Harbor DontFlushMe, the Visualight project acts as an extension of that project and a part of his MFA thesis work done at Parsons New School.

Out of the box the Visualight system connects to data feeds from Twitter, Gmail, Facebook, Weather Underground, the New York City’s MTA (subway & buses), NOAA Tide Predictions as well as any data feed available on COSM. The Visualight can be set to display any combination shade of Red, Green, and Blue that you can think of for your alerts, or can be turned on and off by these datafeeds or directly from your smartphone/tablet. When there are no alerts incoming, the Visualight acts just like any other lightbulb and glows white.

To expand beyond these built-in data feed examples, developers will also be able to add their data sources through the projects API. The code for the system will be available as open source and posted to Github for your viewing pleasure.

Supla is an open-source way to add Internet-connected features to the infrastructure of any building. It consists of software libraries for setting up your own automation modules, mobile apps for controlling them from your smartphone, and a cloud service to manage the back-end setup — all free to use.

Supla Supported Hardware

It’s a very DIY approach, with the assumption that users will be comfortable building their own electronics projects from scratch. To get started you’ll need a Raspberry PiArduino or ESP8266development board; Supla offers software packages for each system. Then you can wire up sensors and actuators to automate lighting, garage doors, window blinds, door locks, appliances and other building elements.

Mobile apps are available for Android and iOS, and Supla’s creators are providing a free cloud service so you can access and control your devices from anywhere with an Internet connection. They’ve also released the source code for setting up your own Supla server.

Supla Supported Hardware

The requirement for tinkering may be a barrier to some, but Supla’s open-source approach offers a more flexible alternative to traditional building automation systems, which have to be installed during construction. It also has potential as a more unified solution than cobbling together a smart building from a mish-mash of standalone retail products.

Visit Supla’s GitHub page to grab the software packages, and check out the forum for ideas and support from the developer community.


OpenMV Cam: IoT Machine Vision

Religious philosophers have long pointed to the eye as evidence for “Intelligent Design”: an organ so complex and intricate that the component parts couldn’t possibly have evolved and come together in just the right way to provide vision through a mere accident of nature. When our inevitable robot overlords start to have a similar conversation about their own origins and capacity for eyesight, maybe they’ll point to OpenMV Cam.

“Machine vision” technologies are nothing new. Digital cameras have been around for decades, and we’re all familiar with software that can recognize elements of digital images like faces, text, and QR codes. But OpenMV Cam puts it all in one place, creating a self-contained development board that can give eyes to any device.

The board includes a microprocessor, a 2-megapixel camera with interchangeable lenses, a pair of infrared LEDs for night vision, and servo headers for controlling tripods and other motors. Developers can expand its capabilities with “shield” modules that add Wi-Fi connectivity, an LCD screen, or infrared heatmap overlays.

Built-in software provides all the building blocks for face recognition, object tracking, recording and streaming video, and other tasks. Developers program OpenMV Cam’s behavior with short Python scripts.

OpenMV Cam is an open-source project released under the MIT license, and the code is available on Github for developers to dig into and collaborate on improvements. As the creators write at Kickstarter: “OpenMV Cam can do a lot right now, but as a community, working together, we can revolutionize machine vision for hobby electronics, education, and artistic pursuits.”
