Flow battery can run for 10 years with zero maintenance
by Jan Buiting @ elektormagazine.com: Harvard University researchers have developed a low-cost flow battery that stores energy in organic molecules dissolved in neutral pH water. In their report (see below) they claim that the new battery can run for a decade or more without...

1.2V-32V @3A Variable Switching Regulator using LM317
The circuit presented here is based on LM317. Generally, LM317 is known as a linear regulator IC, but here the circuit operates as a switching regulator. This circuit operates by transferring energy from the input to the output by using a solid state switch. Power Efficiency of a...

Better current with spin electronics
by Clemens Valens @ elektormagazine.com The ongoing miniaturisation of electronics is expected to reach its limits in the near future. One of the limitations is the size of electrons that are needed in electronic circuits to transport charge from one place to the other, what we...

Measuring seismic activity using ProtoCentral OpenPressure
Seismic activity or "Vibrations of the earth" is measured using ProtoCentral's OpenPressure 24-bit DAQ System. A geophone is a magnetic device used to measure the Earth's normal vibrations (some abnormal during events such as earthquakes). These movements are also present when there...

iSwitchPi Adds an Intelligent Power Switch to Your Raspberry Pi
by Peter Boxler : Native Raspberry Pi does not have an On/Off switch and there is no easy way to shutdown the Pi while keeping the filesystem intact. This Intelligent Power Switch allows just that: Power-On the Pi by pressing a pushbutton and also properly Power-Off the Pi with...
