1.2V-32V @3A Variable Switching Regulator using LM317
https://www.electronics-lab.com/1-2v-32v-3a-variable-switching-regulator-using-lm317/
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 switching regulator is much higher than the […]
Better current with spin electronics
https://www.electronics-lab.com/better-current-spin-electronics/
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 usually call ‘current’. To work around this problem a […]

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 under the hood for a more permanent installation or plugged into the […]
Installing The Micronucleus Bootloader To An ATtiny Via Arduino
https://www.electronics-lab.com/installing-the-micronucleus-bootloader-to-an-attiny-via-arduino/
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 (V-USB), onto an ATtiny84 using Arduino. The Atmel AVR […]

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 functionality. These modules features a 3.2” color TFT display with options for Cover […]
Measuring seismic activity using ProtoCentral OpenPressure
https://www.electronics-lab.com/measuring-seismic-activity-using-protocentral-openpressure/
Seismic activity or “Vibrations of the earth” is measured using ProtoCentral’s OpenPressure 24-bit DAQ System. A geophone is a magnetic device used to measure the Earth’s normal vibrations (some abnormal during events such as earthquakes). These movements are also present when there is a small explosion (commonly used for mining and exploration purposes). Measuring seismic […]
iSwitchPi Adds an Intelligent Power Switch to Your Raspberry Pi
https://www.electronics-lab.com/iswitchpi-adds-intelligent-power-switch-raspberry-pi/
by Peter Boxler : Native Raspberry Pi does not have an On/Off switch and there is no easy way to shutdown the Pi while keeping the filesystem intact. This Intelligent Power Switch allows just that: Power-On the Pi by pressing a pushbutton and also properly Power-Off the Pi with another press on the same button. […]
Teardown and analysis of microwave (26.5GHz) electro-mechanical step attenuators
https://www.electronics-lab.com/teardown-analysis-microwave-26-5ghz-electro-mechanical-step-attenuators/
Teardown and analysis of microwave (26.5GHz) electro-mechanical step attenuators from The Signal Path: In this short episode Shahriar takes a close look at a pair of Hewlett Packard microwave electro-mechanical step attenuators operating up to 26.5GHz. Mechanical attenuators offer excellent repeatability, low insertion loss and nearly limitless linearity. The teardown reveals that the construction of […]
