SparkFun: A look inside some common power supplies


https://www.electronics-lab.com/sparkfun-a-look-inside-some-common-power-supplies/

MTaylor @ sparkfun.com takes a look inside different power supplies he has on his box. Power supplies are everywhere these days. With the advent of switching power supplies, the cost of high-current supplies has radically dropped. Maybe you’ve noticed how the large, heavy, wall-wart style adapters are no longer lurking around your baseboards, falling out of […]

SRF01 Sensor teardown and reverse engineering


https://www.electronics-lab.com/srf01-sensor-teardown-and-reverse-engineering/

Jaanus Kalde wanted to know why his SRF01 sensor fails after dropping from the air so he did a reverse engineering on it. I needed small ultrasonic sensors for a flying sensor. So I got the smallest one – SRF01. Quite nice unit, works down to 0 cm. There were some problems with it – Maximum […]

Phillip Schuster has build a portable device featuring some ports to connect stuff like sensors and other circuits and some menu driven user interface to trigger various modules doing tests, reading data etc. Working in my lab with electronics I came across different little challenges once in a while, and noticed that I am missing […]

Switch Mode Power Supply (SMPS) Topologies (part I)


https://www.electronics-lab.com/switch-mode-power-supply-smps-topologies-part-i/

Microchip’s application note describes the basics of different SMPS topologies: The industry drive toward smaller, lighter and more efficient electronics has led to the development of the Switch Mode Power Supply (SMPS). There are several topologies commonly used to implement SMPS. This application note, which is the first of a two-part series, explains the basics of […]

Replacement LED driver for AN6877


https://www.electronics-lab.com/replacement-led-driver-for-an6877/

Dilshan Jayakody has designed a board to replace AN6877 base LED drivers using discreet transistors. He writes: AN6877 is linear AF level meter IC produced by Panasonic and it is commonly found on many audio equipment. This chip is no longer manufactured by Panasonic and finding replacement chip for AN6877 is also quiet difficult. The circuit […]
