The Nomad 883 is a ready-to-run CNC Mill that’s at home in any environment.
With The Nomad 883 we’ve taken the guesswork out of operating a CNC machine. Everything you’ll need to get started is included – software (for Mac and PC), cutters, cables, even a starter pack of material. You’ll be cutting parts out on day one. The Nomad 883 is fully enclosed to control the mess and limit the noise. You can get a Bamboo enclosure for a home or studio, or a durable HDPE enclosure for the shop or garage.

One, tiny Dart. Power for all your devices. Perfect for your mobile lifestyle.
The Dart is the world’s smallest, lightest laptop adapter. At a powerful 65W it is a perfect complement to today’s thin, lightweight, portable laptops. It fits in a pocket and is designed with a USB port and single outlet profile to make it easy for you to stay charged up when you’re on the road. We hope you are as excited about the Dart as we are and looking forward to finally carrying just one, tiny Dart to charge all your electronics. Join our campaign and never be stuck powerless again!

Allegro MicroSystems have announced the release of its ATS605 range of rotation sensors. This device provides a single chip solution to rotational position sensing of a ferrous gear target. Using three integrated Hall sensors together with Hall interface amplifiers, AGC stage, A/D converter and a synchronous digital controller, the ATS605 is able to accurately resolve the movement of much smaller-toothed cogs than was possible with previous revolution detector solutions.
Signals from the three Hall sensors are routed to two independent differential channels where digital processing with Automatic gain control helps compensate for magnetic variation and system offsets. The open-drain outputs provide voltage output signals which mirror the sensed target’s shape, with a phase separation between the two channels proportionate to the size of the target teeth vs. the Hall element spacing. These produce a highly accurate speed output and can also provide direction of travel information. Devices with an ‘H’ suffix have a maximum operational frequency of 40 kHz. [via]

This week FTDI Chip have announced a range of Arduino-compatible development platforms to support the company’s Embedded Video Engine (EVE) technology. The VM800P series provides engineers with everything necessary to implement Human Machine Interfaces (HMIs) featuring display, audio, touch elements and data processing aspects too.
The units can be programmed using the standard Arduino IDE (using a pre-programmed Arduino-compatible bootloader). In addition to support for various Arduino libraries, every VM800P incorporates an FTDI Chip FT800 EVE graphic controller IC and its FT232R USB interface IC as well as an ATMega328P 8-bit microcontroller running at 16 MHz. Also featured are a touch-enabled display LCD panel, a backlight LED driver, an audio power amplifier and a micro speaker. A choice of 3.5, 4.3 and 5.0-inch display formats is available which have precision fitted bezels to enable operation in industrial environments. The VM800P units also have a USB serial port for firmware upload and application communication, a battery-backed real time clock (RTC) for carrying out system timing and a micro SD socket loaded with a 4GByte SD card containing sample applications.

Organic LED, microprocessor controlled, intelligent energy source for all of your electronic devices.
Legion is a portable energy source with a built-in Organic LED display coupled with a microprocessor. It can charge any USB powered electronic devices. Unlike a traditional portable battery where you’re left in the dark about the state of charge of your battery, Legion learns how you use your electronic devices and displays precisely how much more time (day:hours:minutes) you have remaining until you run out of power. Legion uses premium grade Lithium Polymer batteries designed to maximize your energy density while packing it into the smallest area possible. Legion is proudly designed in Silicon Valley, California.

Scasagrande shared his USB isolator project, that is available at Github:
I received inspiration for the project from other USB isolator projects on the internet. Mine features a few improvements to many of them:
USB-B and micro-USB connectors on the host (upstream) side
In addition to accepting power via the barrel connector (which goes through a basic 7805 low dropout linear regulator), there is also a micro-USB port for device-side power. This allows you to use the now common cell phone charger cube to power your isolated device
Push-button switch for easy USB disconnection events
Bypass jumper for linear regulator, allowing for 5V power from the barrel connector

WatchDuino is an open hardware project that combines inexpensive electronic components and a complex Arduino (C++) code to build a useful and reprogrammable smart watch.
The code and the components have been optimized after a lot of prototypes to provide a rich set of features with a small and cheap battery that can last more than a week without recharging. A lot of electronic and software engineering was required to make this project possible.

Possibly the smallestest ATtiny85 based ‘duino derivative.
Recently, Olimex anncounced the Olimexino 85s, claimed to be the “World’s smallest Arduino ever“. Now, that looks like a challenge. I guess it is about time to show off what has been on my desk since some time last year: The Nanite, pictured below.
I designed this board for fun after the Digispark and, subsequentally, the Adafruit Trinket were announced. The motivation was to have my own ATtiny85 based development board based on a USB bootloader and optimized for the ubiquitous 170 point mini-breadboards. In contrast to the Digispark it even sports a reset button. However, it lacks an integrated voltage converter as it is supposed to be powered by USB.
