Circuit ensures safety in power-on operation
13.03.2017 · Circuits
Computers find universal use in industrial-control systems. During power- and start-up sequences, the outputs of such control systems may yield uncontrolled pulses before the software defines the correct status. If these outputs control the power-on state of a system, these uncontrolled pulses could have dramatic consequences...

The Pixel 2.0 is a tiny OLED screen for your wearable Arduino pleasure
The tiny Pixel 2.0 is basically an Arduino board wedded to a tiny 1.5″ 128×128 color OLED screen. This means you can stick it inside a wearable and address the screen directly from the Arduino board, an improvement on current “solder the screen to the Arduino and hope it works” world of DIY electronics. This teeny-weeny board costs $75 on Kickstarter and should ship in June...
300MHz to 6GHz Dual Wideband Mixer with Programmable Gain Amplifiers Enables 5G Wireless Access
09.03.2017 · News
Linear Technology introduces the LTC5566, a new wideband, high dynamic range dual channel mixer with integrated programmable variable gain IF amplifiers.

Thermal switches provide circuit disconnect
08.03.2017 · Circuits
A single temperature sensor can provide an interrupt to a microcontroller when the measured temperature goes out of range. You need multiple temperature sensors when you have to monitor more than one hot spot. A microcontroller implements the proper protective action when one of the temperature monitors detects an overtemperature condition...
