High Power LED flashing beacon uses a switching regulator
https://www.electronics-lab.com/high-power-led-flashing-beacon-uses-switching-regulator/
This flasher/beacon circuit can be employed as a distress signal on highways, a direction pointer for parking lots, hospitals, and hotels, etc. The circuit uses a power LED, and provides more light than a typical incandescent lamp flasher. Use of a 6 V or 12 V SLA lantern battery makes the circuit portable. The heart […]
Create +/-12V Split Rail From A 5V Bias
https://www.electronics-lab.com/create-12v-split-rail-5v-bias/
With digital semiconductor technology driving system power supplies to lower voltages for higher performance and lower system power, sensitive analog sensor circuits face a growing problem. Much of the inherent noise created in the early stages of an analog sensor signal path is independent of the amplifier bias voltage, so using a higher bias voltage […]

Complex Numbers and Phasors
https://www.electronics-lab.com/article/complex-numbers-phasors/
Introduction Complex numbers are an important mathematical tool that is widely used in many physics domains, including electronics. The concept might seem odd, but their manipulation is simple and their efficiency notable. In the first section, general concepts about the complex numbers are presented in order to get familiar with their representation. A second section […]
tinyPulsePPG – ATTiny85 Pulse oximeter with photoplethysmogram
https://www.electronics-lab.com/tinypulseppg-attiny85-pulse-oximeter-photoplethysmogram/
tinyPulsePPG, an ATTiny85 Pulse Oximeter with Photoplethysmogram (PPG) display by Jeff Magee: This project implemented on an ATTiny85 displays a moving Photoplethysmogram together with pulse rate and estimates of SpO2 – blood oxygen percentage. It uses an SSD1306 128×32 OLED display and a Max30102 sensor. It is emphasized that this should not be used for […]
