TOSHIBA LAUNCHES VOLTAGE DRIVE PHOTORELAY WITH A TINY 2.9MM2 FOOTPRINT

Tiny device features lower input power to reduce equipment size and power consumption Toshiba Electronics Europe (“Toshiba”) announces the availability of a new voltage driven photorelay with a tiny S-VSON4T package and reduced input power dissipation. The new product, designated TLP3407SR, features a maximum LED current of just 1 mA at the input, which represents a reduction to […]

LAPTOP BENCH POWER SUPPLY WITH FAN CONTROLLER

Electronics News Updates / Tismail

Many years ago (September 2009) I made a simple bench power supply using an LT1083 7.5A linear regulator with adjustable output voltage designed to be used with a 19.5V 3.42A laptop power supply. It still works fine after years of abuse, but my choice of output power connectors was poor (3 pin headers, the sort

DIY ANALOG RESOURCE MONITOR FOR YOUR PC

Electronics News Updates / Tismail

Sasa Karanovic build an analog monitoring system that is able to show your computer’s resources on 4x beautiful dials. He writes: In the video above, you can see first a power up sequence where all four dials go from zero to 100% and back to zero after which they start showing real time CPU, Memory, Network

LOW COST HIGH ACCURACY STM32 FFT LCR METER

Electronics News Updates / Tismail

I have always wanted to build a fairly capable LCR meter that could cope with real world use in my own personal lab. This would mean reasonably good accuracy across a wide range of L, C and R. Fortunately, I got the time to do just that this year in the 3rd year Instrumentation module

HOW TO LOWER RELAY POWER CONSUMPTION

Electronics News Updates / Tismail

Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a relay coil may be unattractive for battery-operated applications. You can lower this dissipation by adding an analog switch that allows the relay to operate at a

4.4V TO 105V INPUT SYNCHRONOUS STEP-DOWN REGULATOR DELIVERS OUTPUT OF 1V TO VIN

Electronics News Updates / Ibrar Ayyub

The LT7101 synchronous step-down regulator from Analog Devices is a high efficiency, monolithic synchronous step-down dc-dc converter. It uses a constant frequency, average current mode control architecture and operates from an input voltage range of 4.4V to 105V and provides an adjustable regulated output voltage from 1V to VIN while delivering up to 1A of output current. The LT7101

MYSTERY HP GEAR TEARDOWN

Arduino News / Tismail

What’s round, has what looks like a vacuum tube in the center, and was made in the 1950s by HP? We don’t know either, but [The Signal Path] restored one and shows us this mystery instrument in a recent video that you can see below. We aren’t going to spoil the surprise over what the device is,
