Gary Servin has been working on a new project a method to flash an Arduino via WiFi using the ESP8266:
I’ve been working on a new robot called RoDI for a summer course at my Alma mater. RoDI is a low cost wireless robot to teach robotics and programming I started developing last year (reminder to self: I still need to post about it), but it wasn’t until a month ago that I started to work on it more often.
The first version used a HC-06 Bluetooth module to communicate with the computer. I wanted to to use WiFi, but the cost of the WiFi modules was a problem, since the idea was that the entire robot would cost less than 30 USD. Then, I read about the ESP8266 WiFi modules on Hackaday, and started working on a new version of RoDI, this time with WiFi :D. I wanted to be able to flash the atmega328 inside the robot via WiFi because the robot doesn’t have a USB to Serial converter.

The Bluetooth Special Interest Group (SIG) has published the specs for the next generation of Bluetooth devices. Bluetooth 4.2 has a few improvements that will be of particular interest to developers of IoT devices. The biggest change is support for an Internet Protocol Support Profile (IPSP) which enables IPv6 for Bluetooth. This means that wearable or IoT devices (based on Bluetooth Low Energy) will not need to be paired with a smartphone or tablet to gain access to the cloud, they will have access to the internet via a Bluetooth/WiFi enabled router.

The day I read that a new $5 wifi module was available, I order a few of them to test. Now, a few weeks later I want to share my experience.
This is a very simple demo using the ESP8266 and Arduino to update a remote server (https://thingspeak.com/) using a digital temperature sensor.

I’m not going to explain in detail what is ESP8266 because if you have found this post I’m sure you already know it. But just in case, it is an awesome cheap board (less than 4$) with built-in wifi communication (802.11 b/g/n), and SPI, UART. You can also use its processor to run your code.

Spark has improved and expanded their product line with the Photon wi-fi development board and a pair of new wireless modules for custom circuit boards. The Photon improves on the popular Spark Core microcontroller by adding 802.11n wi-fi connectivity, SoftAP for provisioning, more memory, and a faster ARM Cortex M3 processor. Like the Core, it sits right into a standard breadboard for easy prototyping. And best of all, it can be had for $19.

In a serious case of out-of-the-box thinking, a design team at Roost in Sunnyvale California have come up with a method to add Wi-Fi connectivity to your old smoke or carbon monoxide alarm by just swapping batteries. Your smoke detector uses a 9 V PP3-type battery right? The new Roost battery contains 9 V lithium cells together with a processor and Wi-Fi chip in the standard PP3-sized battery outline. It monitors the battery voltage and power drain to alert you via Wi-Fi and a smartphone app when the alarm has been triggered, even if you are not at home.

Find out the WunderBar – the OpenSensor Cloud Platform enabling to easily develop applications for the physical world.
The WunderBar IoT (Internet of Things) Starter Kit from company relayr mimics the appearance of a chocolate bar with a WiFi enabled master module, plus six detachable smart sensor mini-modules.
The WunderBar Internet of Things WiFi & Bluetooth Sensor Starter Kit is a quick start development tool for software application developers unfamiliar with complex wireless hardware designing, and a complete open-source wireless hardware reference design. WunderBar provides to hardware design engineers an out-of-the-box development tool that helps users get started quickly building, inventing, developing, and experimenting with Internet of Things senor based designs using WiFi and BLE senor applications.
Made of seven modules, the WunderBar main module is fitted with an ARM Cortex ‘M’ micro -processor, which connects to the internet through the WiFi unit. Bluetooth Low energy is used to communicate with the other modules. All of the activity that happens around the WunderBar is sent to the WunderBar platform, where you can easily access and work with the signals.
Break, place and program
It works right out of the box. It is energy efficient, fast, secure and designed for developers, makers and manufacturers.
WunderBar has six powerful smart modules, each equipped with its own Bluetooth Low Energy (Beacon) processors and battery that can power the units for up to a year. Light / Color / Proximity, Gyroscope / Accelerometer, Thermometer / Humidity, IR Transmitter (remote control), A connector to the easy Grove System of Sensors and Actuators that are all Arduino compatible and a Noise/Sound sensor. The Starter Kit has available for download various software development kits (SDKs) for iOS, Android and Node.js. including test Apps which can be downloaded from relayr.io. Libraries for node.js, python and more will be supported soon.
WunderBar is the easiest way to create innovative and useful apps to connect smart devices without needing to learn about hardware. App developers can quickly access data from the physical world with WunderBar’s easy-to-use SDKs for iOS, Android and Node.js or with our simple REST API.
Because the WunderBar is still a dev kit, with a little bit of knowledge, and the exposed GPIO pads, you can make almost anything you want smarter. More info at: www.relayr.io/wunderbar The WunderBar will soon be our standard stock item.

This is a Solar Tracker. A full size, internet cloud connected, smartphone accessible Solar Tracker built mainly from 2x4s and plywood, employing wooden peg gears, recycled curtain poles, nuts, bolts and threaded rod. The solar tracker uses a home built electronic controller incorporating WiFi, stepper motor drives, accelerometer and magnetometer. The tracker was designed to drive a full size 90W panel in azimuth and elevation. The gears driving the tracker are wooden peg gears commonly used in the 16th century. The gears were designed using modern 3D CAD (Solidworks). Connecting the wooden peg gears to the internet cloud just seemed like the right thing to do. This is not a waterproof design – you will need to consider modifications to waterproof your derivative design.

The Arduino’s greatest weakness is also it’s greatest triumph. That is, it is only a low power simple processor, which makes internet connectivity for such a simple device difficult. Often the network interface has a few orders of magnitude greater performance than the arduino atmel avr processor itself.
Arduino Yun is the answer to wifi connectivity for arduino. Ushering in a new era known as the internet of things, Yun is actually a complete 400mhz system on chip. There is irony in the fact that the powerful system on chip’s only duty is to serve the lowly AVR. Akin to “You Pass Butter”
