Traditionally, you would need to install an IDE, which includes all the necessary software, find and install the correct drivers, set permissions, etc. It can take 10-60 minutes. Or it can be a total mess.
With codebender, you can program your Arduino straight from your browser. No need to find, install, update and manage libraries and drivers. codebender does that for you. Just install our browser plugin and follow our Getting Started guide. From having an Arduino, to having a programmed Arduino. In mere minutes.
After installing the pluggin, you can flash any codebender sketch to your device. See the code bellow? You could load that to your device, straight from this page!

OMG! All the electronic and mechanical engineers I know (and even most of the marketing folks) are going to squeal like schoolgirls when they get their sticky little hands on this amazing, free 3D design software that will enable conceptualization and rapid prototyping, reduce costs, and dramatically accelerate product development. In short, this software is like a “Gift of invention that will bring your ideas to life!”
Quiet down my racing heart! I just heard the most amazing “hot-off-the-press” news. In just a few days as I pen these words, all of us who wish to will be able to design 3D models, assemblies, and enclosures for our designs using some incredibly intuitive, fully-featured 3D modeling software. And, best of all, it’s free! (And when I say “free” I really mean free, as in free for both commercial and non-commercial use with no limitations or licensing.)

Texas Instruments designers have developed an entirely new data converter with the LDC1000 inductance-to-digital converter (LDC) designed specifically for inductive sensing applications.
The LDC uniquely combines all of the external circuitry on chip that is normally required to simultaneously measure the impedance and resonant frequency of an LC resonator. It then regulates the oscillation amplitude in a closed loop to a constant level, while it monitors the dissipated energy of the resonator. This leads the accurate measurement of inductance of the front-end LC circuit, which enables precise measurement of linear/angular position, displacement, motion, compression, vibration, metal composition and new applications which will be conceived by designers. All of this can be done in the presence of oil, dust, dirt and moisture unlike most other solutions.

Until recenty my desktop computer has always shared a room with a Hi-Fi setup so there has never been a need for using decent speakers with the computer. When the desktop computer was moved into it’s own room (with no HiFi) I quickly realized that good speakers were now required for decent quality music playback. I had been using some low cost Radio Shack speakers with an inexpensive Tripath based amplifier and I was really itching for an upgrade.

The circuit in Figure 1 lets you switch high-voltage power to a grounded load with a low-voltage control signal. The circuit also functions as a submicrosecond circuit breaker that protects the power source against load faults. Power switches to the load when you apply a logic-level signal to the output control terminal. When the signal is lower than 0.7V, transistor Q3 is off and the gate of P-channel MOSFET Q4 pulls up to the positive supply through R6, thus holding Q4 off. During this off condition, the circuit’s quiescent-current drain is 0A.

Electric Imp Solar Powered Temperature Logger
The first hack I did with the imp was a solar powered temperature logger using a TMP36 sensor and send the data to ThingSpeak

A new STM32F4 discovery board has been announced, featuring a 2.4″ QVGA TFT LCD (without touch sensor), 64Mbit of SDRAM, a Gyro and all pins available through pin headers. The data brief is available for download and the board lists for $24USD. [via]

With a height of only 4.5 mm are new terminal blocks able to connect LED modules and LED panels aesthetically and with a maximal reliability.
There are numerous SMT connectors on the market, which are suitable for usage on LED panels but even in other applications. That´s why it´s a logic question – why just Wago 2060?
Firstly it is because of a sophisticated construction of a terminal block with a globally known and million times proven screwless spring clamp CageClampS. This clamp has an optimum pressure on a wire ideally responding to a wire diameter, i.e. the thicker wire, the bigger pressure. Also thanks to this is the max. allowed current up to 9A (!). Further, it´s possible to install solid and ferruled wires even without tools. By a simple pressing to a terminal block (for example by a screwdriver), it´s possible to insert even fine stranded flexible leads and by similar way also to disengage. Features of a clamp don´t get worse neither after multiple disengaging of a connection and they remain stable even after a long period of operation.
From other positives it´s necessary to mention a “balcony” construction of an input portion, which makes installation of wires easier and faster. Sufficiently big flat area ensures a reliable application on assembly machines (pick-n-place). And finally – an aesthetic curved shape and a white/cream color cause, that connectors are inconspicuous and they don´t disturb on a PCB.
Terminal blocks are available in 1,2 and 3-pole version. You needn´t be in doubt that you missed development and you still don´t know a circuit operating on 1 pole – naturally the single-pole version is intended for connecting of several modules into series. A big plus is also availability of interconnecting both-sided pins enabling easy and aesthetic creation of a row (string) of several modules.
Pin spacing is 4mm and there´s also available a version with 8mm pin spacing with operating voltage of up to 600V. Connector casing is made of an advanced material (glass fibre reinforced PPA) with a very wide range of operating temperatures.
Novelty is also a newer version – Wago 2061 with up to 12A max. current. Detailed information will provide you the Wago 2060 brochure.

My most rewarding projects are the ones which i actually use. I like my audio gear so, this was the perfect companion project! On my desk i have a headphone amplifier for my AKG K702′s headphones, below it i have my self built Onixia integrated amplifier for my bookshelf speakers. I have been thinking about making a global volume control for both devices for quite some time… here is the results of my efforts.

In an effort to resume previous work [A, B, C, D] on developing a crystal oven for radio frequency transmitter / receiver stabilization purposes, the first step for me was to create a device to accurately measure and log temperature. I did this with common, cheap components, and the output is saved to the computer (over 1,000 readings a second). Briefly, I use a LM335 precision temperature sensor ($0.70 on mouser) which outputs voltage with respect to temperature.
