The project shown here is a cheap 60W LED dimmer for 12V LEDs/12V LED strips. The circuit is based on the very popular, versatile, and low-cost 555 timer IC, NE555 IC generates a PWM signal and IRF540 MOSFET works as output driver for the LEDs. In this circuit the 555 IC used in an...

App note from IXYS about their unique digital inrush controller using Zilog’s 8-bit Z8F3281 MCU. Digital control allows distinctive solutions to control inrush current in typical AC-DC rectifier with capacitive load by limiting capacitor pre-charge current to a predetermined value at...

A GitHub user called Wagiminator has posted details about ATtiny84-TinyCalibrator, which is an OSC Calibrator and High Voltage Fuse Resetter for 8-Pin ATtinys. The ATtiny84 was chosen as the microcontroller for the TinyCalibrator because it has exactly the necessary number of GPIO...

Τecate Group's TPLC series combines the high power density of an ultracapacitor and the rich energy density of a lithium battery Tecate Group's TPLC series is UL recognized and RoHS and REACH compliant. The capacitors are ideally suited for applications requiring increased voltage,...

By Hesam Moshiri and Anson Bao In this article/video, I introduced an adjustable 30V-4A linear power supply that provides constant voltage and constant current adjustment. The output noise of the power supply is low and has measured using the power analysis feature of the Siglent...

Harry Baggen writes: Every electronics enthusiast will have one or more multimeters. But have you ever considered purchasing a bench multimeter instead of a hand-held one? These usually offer many more features and a better display. The Siglent SDM3045X is a 4½-digit bench multimeter...

This is a high accuracy current sensor project build using ACS37002 IC from Allegro, which is a fully integrated Hall-effect current sensor with 0.85mOhms integrated conductor. A fast overcurrent alert output, programmable gain settings and analog linear voltage outputs are key features...

There are many Mini Circular Saws available in the market, and it might be confusing getting one appropriate for you. I recently stumbled upon one of such saws, a 110V/220V Electric Mini Circular Saw. The circular saw is suitable for making straight cuts in wood, wood-like material,...
