Shrunk down an Arduino to the size of a finger-tip! by Open Source RF RFduino: A finger-tip sized, Arduino compatible, wireless enabled microcontroller, low cost enough to leave in all of your projects! The RFduino has Bluetooth 4.0 Low Energy built-in, which enables it to wirelessly talk to any smartphone that has Bluetooth 4.0. Currently we have several open source apps built for the iPhone which were used in our demos. The RFduino has a Nordic 32 bit ARM Cortex-M0 processor, so it has more power then the UNO, however it still runs the same, simple Arduino code the UNO runs, so there is no need to learn any new programming language or environment. The RFduino GPIO lines all support, Digital IO, Analog ADC, SPI, I2C, UART and PWM. The RFduino is similar to the Arduino UNO or DUE, except the RFduino is a fraction of the cost and size, in addition has wireless smartphone connectivity built-in! Up to now, adding wireless to an Arduino required an additional wireless shield which adds cost and size. It can be used with or without Bluetooth 4.0. - Armen
Spark Store | Open source IoT toolkit Exclusive: Nest has raised another $80M, now shipping 40K+ thermostats a month Smart thermostat startup Nest has closed on a round of $80 million, we’ve learned, and the funding was done at a post money valuation of $800 million. Google Ventures led the round, and Venrock participated as a new investor, according to our sources. Nest is currently listed on Venrock’s site. The company has raised this round to continue its growth; it’s now shipping 40,000 to 50,000 of its learning thermostats per month. If the company’s growth continues at this current rate, Nest could reach a shipment rate of 1 million thermostats per year by the summer, say our sources. Some of that growth is happening in Europe, in addition to its shipments in the U.S. Nest also plans to use the funds to offer a more comprehensive smart home service along with its product, which could include lighting and alarm systems, too, we’ve heard. We’ve reached out to Nest and are waiting to to hear back on these figures. Nest previously raised tens of millions of dollars before this round.

Smart Thinking “Poor Roo,” my friends say about my seven-year-old Corgi mix. “Don’t you think he minds having his every moment broadcast online?” The fact is Roo has become the unwitting subject of my electronic hacks. One of my recent experiments involved attaching an UP by Jawbone band to his harness to solve the mystery of just what he does all day. I must admit the first set of graphs was disappointing — it seemed like he did nothing but nap. Questioning the data, I reset the band to track a 27-lb, 14-inch tall “person”. Yep, I like to measure things Thankfully, I’m not the only one who likes to experiment with technology. As a designer, I’m really excited by this shift in how we relate to the everyday objects around us. What all this adds up to is a virtual database of physical objects — or “Internet of Things” — that can be accessed at any time. As inspired as I am by the possibilities, it’s also my job to keep things real. 1. 2. 3. 4. 5. 6.
Turning the Raspberry Pi Into an FM Transmitter - Imperial College Robotics Society Wiki Steps to play sound: (Created by Oliver Mattos and Oskar Weigl. Code is GPL) sudo python >>> import PiFm >>> PiFm.play_sound("sound.wav") Now connect a 70cm (optimally, ~20cm will do) or so plain wire to GPIO 4 (which is pin 7 on header P1) to act as an antenna, and tune an FM radio to 103.3Mhz. Download the module here: [Download Now!] (this contains both source and a ready to go binary. New! sudo . How to change the broadcast frequency Run the . The second command line argument is the frequency to transmit on, as a number in Mhz. sudo . It will work from about 1Mhz up to 250Mhz, although the useful FM band is 88 Mhz to 108 Mhz in most countries. Most radio receivers want a signal to be an odd multiple of 0.1 MHz to work properly. The details of how it works Below is some code that was hacked together over a few hours at the Code Club pihack. If you're v. smart, you might be able to get stereo going! Accessing Hardware
