PORTLAND, Ore. — Laying claim to the world’s smallest high-precision inertial measurement unit (IMU) Epson Electronics America, of San Jose, Calif., unveiled its six-degrees-of-freedom (DoF) combo accelerometer/gyroscope chip, which measures a scant 12x10x4 millimeters, at the annual meeting of the Association of Unmanned Systems International 2013 (AUVSI, Aug. 12-15, Washington, D.C.). Cast in its quartz-micro-electro-mechanical […]

I’m planning to build a EEVblog-ish constant dummy load for battery and power supply testing. Dave in his build used a LCD voltmeter for the display. In the senseless pursuit of difference, I tried other display solutions including character LCD, graphics LCD, OLED, TFT, AMOLED, IPS, which resulted in several previous blogs but nothing ends up […]

(Phys.org) —Two teams of astronomers using the NASA/ESA Hubble Space Telescope have discovered three distant exploding stars that have been magnified by the immense gravity of foreground galaxy clusters, which act like “cosmic lenses”. These supernovae are the first of their type ever to be observed magnified in this way and they offer astronomers a powerful tool to check the prescription of these massive lenses.

Description Create a design and simulate using EE-Sim: [MAX17515] The MAX17515 is a fixed-frequency, step-down power module in a thermally efficient system-in-package (SIP) package that operates from a 2.4V to 5.5V input supply voltage and supports output currents up to 5A. The device includes switch-mode power-supply controller, dual n-channel MOSFET power switches, a fully shielded […]

Alaska’s seismic network records thousands of quakes produced by glaciers, capturing valuable data that scientists could use to better understand their behavior, but instead their seismic signals are set aside as oddities. The current earthquake monitoring system could be “tweaked” to target the dynamic movement of the state’s glaciers, suggests State Seismologist Michael West, who will present his research today at the annual meeting of the Seismological Society of America (SSA).

With the Traco TPC120 AC/DC module you´ll gain a reliable power source for an excellent price and you´ll easily meet even the newest energy regulations (ErP). Swiss company Traco Electronic is known as a producer of top-quality switch-mode power supplies TracoPower used even in atomic power plants etc. In the portfolio of this company can […]

(Phys.org) —A group of senior university officials suggests it is time to add faculty research activities that translate into patents, licensing and commercialization of products to the traditional model for faculty tenure and career advancement , which for years has been based primarily on research and publication in scientific journals.

Since the coming of the Raspberry Pi Model B, single-board computers (SBCs) have become a prevalent force in the development world. These pocket-sized devices have taken the online maker community in particular by storm, providing PC functionality to a plethora of open-source projects in amazingly compact, cost-effective, and low-power platforms. It’s not an overstatement to […]

From the beginning, the MC HCK was conceived to be not only cheap to produce and sell, but it was also conceived to be buildable at home, at a low cost. In this post, we’ll show how to build a MC HCK at home. Getting the Parts All required and optional parts are listed in […]

The silicon MOSFET has become a key component in the design of DC/DC converters, providing the high-speed switching and current-handling capability needed to implement high-efficiency, pulse-width-modulation-based control strategies. The drive towards higher efficiency is placing more intense demands on MOSFETs, particularly in designs that have constraints on size, reducing the amount of space that can […]
