Time Machine – A Smart Clock That Does What You Say Using Alexa Voice Service
https://www.electronics-lab.com/time-machine-smart-clock-say-using-alexa-voice-service/
With a controller and a seven segment display, showing the time is not a so special feature, but when this clock can listen to the user and do what they want, that’s what worth highlighting a “Time Machine”. Analysing human voice and take action based on that is not so simple. That’s why using a […]

The ESP-32 datasheet was released […]
LTC Design Note: Dual 9A, step-down μModule regulator with digital power system management
https://www.electronics-lab.com/ltc-design-note-dual-9a-step-%ce%bcmodule-regulator-digital-power-system-management/
Jian Li, Yingyi Yan and Marvin Macairan have published a Design Note based on LTM4675 dual DC/DC regulator. The LTM4675 is a dual 9A or single 18A step-down μModule (micromodule) DC/DC regulator featuring remote configurability and telemetry monitoring of power system management (PSM) parameters over PMBus—an open standard I2C-based digital interface protocol. Its 16mm × […]
Tracespace Online Gerber Viewer (beta)
https://www.electronics-lab.com/tracespace-online-gerber-viewer-beta/
This particular PCB viewer takes your Gerber and drill files and gives you individual layer renders as well as very fancy renders of what your completed boards are going to look like. The tracespace viewer accomplishes all this locally (nothing gets sent to any server!) by converting your files to SVGs. Thanks to the “Scalable” […]
How to Build a Class-D Power Amp
https://www.electronics-lab.com/build-class-d-power-amp/
Cezar Chirila @ allaboutcircuits.com shows how to build a Class-D amplifier which has amazing efficiency. What is a Class-D audio power amplifier? The answer could be just a sentence long: It is a switching amplifier. But in order to fully understand how one works, I need to teach you all its nooks and crannies. How to Build […]
