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...

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...

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...

Jesus @ jechavarria.com tipped us with his latest project. He writes: For several months I’m working with FONA808 modules from Adafruit to make a portable, web-based locating system. This modules are based on the SIM808 module from SIMCOM manufacturer, and integrates both GSM and...

Car hacking applications have been growing during the last few years, making it faster and cheaper to get into automotive tinkering. A new device was launched recently on kickstarter called M2 by Macchina. M2 is an open-source, versatile development platform which can be wired...

In order to be able to upload Arduino sketches directly to the ATtiny84 over USB without the need to use a programming device, Shawn Hymel, an electrical engineer at Sparkfun Electronics, had published a guide showing how to install the micronucleus bootloader, which supports virtual USB...

Microchip, the well-known manufacturer of microcontrollers and semiconductors, announced this week a new family of 8-bit PIC microcontrollers, the 'PIC16F15386'. The new PIC16F15386 family features a 8 MIPS CPU speed, with 2KB RAM and up to 28KB flash memory offered in 8 to 48-pin...

4D Systems, the manufacturer of intelligent graphics solutions, has announced a new 3.2” smart display module as part of the ‘ gen4 ’ series, which had been designed specifically for ease of integration and use, with careful consideration for space requirements and...
