ARM has introduced its highest performance Cortex-M series processor core. The Cortex-M7 retains the same instruction set of the other processors in the Cortex M series, but has been given a six-stage super scalar pipeline architecture which dramatically increases its performance over the previous Cortex-M4. Ian Johnson, product manager at ARM told Electronics Weekly, the […]

Stepper motors are great for accurate positioning because they move in discrete steps – a feature that makes them very appropriate for CNC software control. But every once in a while you have an application where you need to press a button and rotate some kind of a jig at a preset angle or move

Hi all! With a bit of delay, here’s my last work, a PICnano breadboard based on the PIC18F2550microcontroller. I have in mind a new project and I want to use an small board, like the Arduino Nano board. This new project is battery powered (3,7V Li-Ion battery). After checking the schematics of the Arduino Nano, I see

Cree has introduced a multi-die 500 lm (80CRI, 3,000K) surface-mount lighting LED, aiming to compete against multiple single-die medium-power LEDs in automated luminaire manufacture. The idea is analogous to the way bolt-down multi-die chip-on-board modules (CoBs) are taking-on single-die LED boards in manual assembly lighting manufacture. Named MH-B, the new LED “combines the reliability and
Surface-mount array takes on medium-power lighting LEDs Continue Reading

Toshiba has announced a new 20-megapixel (MP) 1.12-micron CMOS image sensor (CIS) for high-end mobile handsets and smartphones with 1080p resolution. With an optical height of 1/2.4 inch, the T4KA7 sensor enables the development of camera modules with a z-height of 6mm or less to meet consumer demand for ultrathin and ultralight mobile devices. The
20 MP CMOS image sensor from Toshiba Continue Reading
A “Joule Thief” is a simple voltage booster circuit. It can increase the voltage of power source by changing the constant low voltage signal into a series of rapid pulses at a higher voltage. You most commonly see this kind of circuit used to power LEDs with a “dead” battery. But there are many more

Smart meters will only save 2% on consumers’ bills – an average £26 per household per year – according to the Public Accounts Committee (PAC) – a committee of MPs – which disagrees with the opinion of the Department of Energy and Climate Change (DECC) that smart meters will lower bills and make switching easier. “Smart
Smart meters a waste of money, say MPs Continue Reading
