by Graham Prophet @ eedesignnewseurope.com Maxim Integrated has posted details of a battery charge monitor IC for which it claims the lowest quiescent current available, at 7µA. The 1-cell Fuel Gauge with Maxim’s ModelGauge m5 EZ algorithm can eliminate battery characterization...

Rex Niven @  edn.com has a design idea on how to drive a character LCD using only one wire. This hardware interface Design Idea reduces the connection to just one wire, allowing a basic microcontroller with limited I/O to drive a large display, either directly, through a standard...

Kionix (Ithaca, New York), part of the Rohm Group, has added the KXTJ3 3-axis low-cost accelerometer that offers the performance of a more expensive accelerometer in a 2 x 2 x 0.9 mm form factor. By Graham Prophet @ eedesignnewseurope.com The company presents the device as a high...

Afroman reviews Siglent's SSA3000X series spectrum analyzer and all the options. There is some RF information for beginners and usage experiments are also performed. Siglent SSA3032X Spectrum Analyzer Review & Experiments -...

The circuit diagram presented here is about a negative voltage regulator. It is based on LT1054, which is a switched capacitor voltage converter with regulator from Texas instrument. This device has many advantages over other previously available switched capacitor voltage converters....

Graham Prophet @  eedneurope.com presents the latest ultra-low dropout regulators from Diodes Inc: The AP7380 series of ultra-low dropout regulators (Diodes Inc.) operates from an up-to-24V input voltage range and offers fixed output voltage options, in USB power, portable...

Nikos Stavrou @ instructables.com build a bi-fuel trip computer using arduino and has a detailed tutorial on it. The computer can measure both LPG and unleaded fuel consumption. He writes: The main reason I made this project is the lack of a trip computer that is designed for LPG...

Pieter @ piconomix.com tipped us with his latest build. Check it out on the link below. I recently had to create a programming jig for an ATmega328PB based board. 1mm diameter test pads were placed on the bottom of the PCB to give access to the ISP pins. Normally one would add two...
