Wireless Arduino-compatible miniatures The IoT platform GroveStreams is a new IoT platform in the cloud designed to interact with users and remote M2M networks. Some developers let us know their interest in integrating with GoroveStreams since it seems to be providing some nice capabilities such as: On-line graphs and data logsEvent handling and calendarsSMS alertsGUI widgets that can be inserted into custom web pagesRESTful API Lagarto-MAX is very adaptable to this kind of online services so we accepted the challenge to add compatibility for GroveStreams. This took us a few hours except for some minor issues that were rapidly solved thanks to the excellent support provided by the GroveStreams development team. GroveStreams introduces a new concept called "component template", which lets us format data streams in a common way.

SphereBot | Pleasant Hardware The SphereBot can plot images on spherical objects like table tennis balls, golf balls, eggs etc. It is inspired by the original EggBot by EvilMadScientist, but built from 2 old stepper motors and some steel rods (all cannibalized from old flatbed scanners), some MDF and plywood and a few 3d printed parts (printed with my MakerBot Cupcake). The electronics are simply an Arduino and two Polulu A4983 stepper motor drivers (on the bread board). The custom Arduino firmware directly interprets GCode sent over the serial port. So it’s no problem to print GCode from MakerBot Unicorn designs directly on the SphereBot. Thanks to the excellent Inkscape plugin from Marty McGuire, it’s easily possible to convert all kinds of vector drawings (eps, svg, etc) to printable GCode. The firmware is open source and can be found here: Arduino firmware: Mac OS X GCode sender application: [Update 04/09/2011] {filelink=3}

Tutorials | Flutter Wireless Primer #001: What's an Arduino Skill level: [Beginner] Arduino is an electronics prototyping platform, which is a fancy way of saying "Arduino makes it easy for regular people to build electronics". Specifically, Arduino makes it easy for people to build electronics that run simple computer programs (they don't *have* to be simple though, people build flying robots with this stuff). Lets say you have some project, where you want to flip a switch and have an LED turn on. The entire electrical circuit is just a battery pack wired to a switch, then a resistor, then the LED, then the wires go back to the battery. Flip that switch and the LED turns on! But what if you only want the LED to turn on when certain conditions are met? You need a temperature sensor, but where would you add it to the circuit? That can be tricky to do with just electronics, but it's easy to do with software, and that's where Arduino comes in. [Arduino code editor, showing an entire program for blinking an LED.]

Home Environmental Sensors: Ninja Sphere We’ve told you before about Ninja Blocks, a home automation system that couples wireless sensors with simple software to create rules for things like motion detection alerts and remotely switching lights on or off. Now the eponymous Australia-based startup behind Ninja Blocks is hard at work on the next evolution of the connected home: the Ninja Sphere. In addition to the environmental sensors of the Ninja Blocks system, the Ninja Sphere will be able to connect to just about any wireless device through WiFi, Bluetooth, or ZigBee (a wireless standard for low-power devices). That means your phone, webcam, and WiFi-enabled TV can all be part of your Ninja Sphere, along with any number of third-party home automation gadgets. The heart of the Ninja Sphere is the Spheramid base station. Where the possibilities really open up, though, is in the Ninja Sphere’s location tracking ability.

FM Bug Transmitter Mint Box - Theory The LC Oscillator Is A Tank Circuit It was discovered pretty early on in electronics that if you put an inductor and capacitor in parallel with each other, they will resonate at a specific frequency. Ideally charge flows back and forth between the 'top' and 'bottom' capacitor plates generating this resonant frequency (similar to how a pendulum swings back and forth). The LC Oscillator Formula If we plug in the values seen above, the oscillator should create the correlating frequency and in an ideal world that is what happens. An LC Oscillator Simulation Spice is usually the tool of choice when simulating any electronic circuits. The green probe looks at the voltage at that specific point over a period of time. If you look closely you can see the period is just about 10nS as expected. Now that we have a little more understanding of how the oscillator is made, how the audio signal is amplified and how the FM signal is created let's move forward and actually build this thing!

Grove - Moisture Sensor - Wiki This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. They can be very easy to use, just insert it into the soil and then read it. With the help of this sensor, it will be realizable to make the plant remind you : hey, i am thirsty now, please give me some water. Note:This sensor isn't hardened against contamination or exposure of the control circuitry to water and may be prone to electrolytic corrosion across the probes, so it is not advisable to be left in place or used outdoors.

Open Source Automation - Automation software for the home and more. MOSFET MOSFET showing gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (white) Two power MOSFETs in the surface-mount package D2PAK. Operating as switches, each of these components can sustain a blocking voltage of 120 volts in the OFF state, and can conduct a continuous current of 30 amperes in the ON state, dissipating up to about 100 watts and controlling a load of over 2000 watts. A matchstick is pictured for scale. A cross section through an nMOSFET when the gate voltage VGS is below the threshold for making a conductive channel; there is little or no conduction between the terminals drain and source; the switch is off. Simulation result for formation of inversion channel (electron density) and attainment of threshold voltage (IV) in a nanowire MOSFET. The 'metal' in the name MOSFET is now often a misnomer because the previously metal gate material is now often a layer of polysilicon (polycrystalline silicon). [edit] where
