The OPT3001 is a sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye and includes significant infrared rejection. The OPT3001 is a single-chip lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and […]

Silicon Labs introduced a new family of high-precision temperature sensors offering industry-leading power efficiency. Silicon Labs’ ultra-low-power Si705x temperature sensors consume only 195 nA (typical average current) when sampled once per second, which minimizes self-heating and enables multi-year coin cell battery operation. Unlike traditional digital temperature sensors, the Si705x devices maintain their accuracy across the
LED Engin has announced a quad die infra-red LED emitting 4.5W of flux, from 850nm and 940nm variants. “The four die parts are the world’s most powerful IR emitters,” said the firm, which has also released some deep red emitters. Called LZ4, the IR LEDs have a 7x7mm footprint and the firm’s dual-junction emitters. Heat

SAN FRANCISCO and MINNEAPOLIS, January 26, 2015 — Punch Through Design, a hardware and software development firm that brings Bluetooth Low Energy hacking to the masses, has released the Windows Bean Loader, the first-ever wireless Arduino programming app for Windows users. Using the loader app, Windows-based developers and hobbyists can easily upload code to their

NAND process geometries have become as problematic as logic process geometries with the advantages of further scaling – especially as 3D NAND approaches – being questioned. NAND process geometry is currently at 20nm and should be 10-20nm in 2017, says IC Insights adding “reported minimum feature sizes and mass production definitions are very imprecise and
NAND scaling issues becoming more complex Continue Reading
Compact installation step relays Finder 26 series save energy similarly like latching relays, but they also operate on AC voltage. Step relays are able to effectively control lighting or other devices and they significantly simplify circuit complexity at the same time. If you´re familiar with a bistable (latching) relay, then you know, that a relay
With a step relay Finder 26 can be saved energy and also installation costs Continue Reading
STMicroelectronics have announced the LSM6DB0, the latest addition to its iNEMO family. It packs a 3-axis accelerometer, 3-axis gyro and low energy ARM-based Cortex processor in a tiny 3 x 3 mm package. This chip is designed to interface with baseband chipsets that don’t have a sensor co-processor. Additional external sensors can also be hooked
A 6-axis Inertial Motion Sensing Device Continue Reading
Ever wondered what the Bitcoin currency means to the electronics industry? Well, there is a Bitcoin electronics ecosystem, and it seems to be growing. An early developer of hardware systems for Bitcoin mining is US-based CoinTerra and it has recently expanded its business by acquiring Europe-based Bitcoin related software company Bits of Proof. Dubbed the
Chip technology behind the Bitcoin phenomenon Continue Reading
For this dandy little project you’ll need: Arduino – I’m using an Arduino Uno a 3 x 4 keypad a 16 x 2 LCD screen a laser module/sensor a light dependent resistor (LDR) a buzzer 3 x 220 ohm resistors 1 x 10K resistor 1 x 10k potentiometer (optional, it’s to adjust the LCD screen

I’ve made a few devices already that have used 0603 SMD LEDs. 0603 LEDs are beyond tiny and they’re a little trickier to work with when orientation matters. If you look closely at the back of the LED, you’ll notice some markings that indicate which end is the cathode, but in reality it’s really easy
