Building our own backup server using the Raspberry PI
by Michal Remias @ wpress.io: We’ve been always thinking about building our own backup server using the ARM solution of Raspberry PI. When we needed to manage approx. 25 WordPress web projects couple of months ago we did some experiments with MainWP on virtual server at...

Bias generators with ultralow noise and ripple for sensitive circuits
The LT®3095 generates two low-noise bias supplies from a common input voltage ranging from 3V to 20V. Each channel includes a fixed frequency, peak current-mode step-up switching regulator and a low-noise, singleresistor- programmable 50mA linear regulator. The linear regulator’s...

Simple Infrared Barrier
by Maurizio @ dev.emcelettronica.com: Although a remote control is not so difficult to design and build, there is an even simpler option: the IR barrier. This consists of a constant IR signal permanently going from an emitter to a receiver, both of them being in two different places...
