60W LED Dimmer for 12V LEDs using 555 Timer
https://www.electronics-lab.com/60w-led-dimmer-for-12v-leds-using-555-timer/
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 astable […]
+/-18V Isolated DC-DC Converter Dual Supply Output from USB 5V Power Input
https://www.electronics-lab.com/project/18v-isolated-dc-dc-converter-dual-supply-output-from-usb-5v-power-input/
This is a mini DC-DC converter with dual output from single 5V DC supply or USB power source (e.g., +/-18V from 5V/USB). The mini board will fit into small space and perform with high efficiency. Basically, the circuit transfers power from 5V/USB to the output side +/-18V with high isolation, without a direct connection between […]
App note: Digital inrush controller
https://www.electronics-lab.com/app-note-digital-inrush-controller/
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 each half sine-wave cycle. Capacitor charge is spread over a number of cycles until […]
ATtiny84 OSC Calibrator and High Voltage Fuse Resetter
https://www.electronics-lab.com/attiny84-osc-calibrator-and-high-voltage-fuse-resetter/
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 pins. 8-pin ATtinys usually feature few GPIO pins available, so they are usually operated without an […]
TPLC™ 3.8 V Hybrid Capacitors Series comes up to 350F
https://www.electronics-lab.com/tplc-3-8-v-hybrid-capacitors-series-comes-up-to-350f/
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, higher energy density, and an exceptional cycle life that is not available […]
30V/4A Adjustable Power Supply (CC-CV)
https://www.electronics-lab.com/30v-4a-adjustable-power-supply-cc-cv/
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 SDS2102X Plus oscilloscope. All component packages are through-hole, so you […]
Elektor Review: Siglent Bench Multimeter SDM3045X
https://www.electronics-lab.com/elektor-review-siglent-bench-multimeter-sdm3045x/
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 with a basic accuracy of 0.02% and many interface options. Here follows […]
High Accuracy Current Sensor with 400Khz Bandwidth using ACS37002
https://www.electronics-lab.com/high-accuracy-current-sensor-with-400khz-bandwidth-using-acs37002/
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 of this project. The sensor has optimized accuracy for current ranges +/-33A to […]
