Würth Elektronik – a huge range of inductive components
https://www.electronics-lab.com/wurth-elektronik-a-huge-range-of-inductive-components/
Würth Elektronik is one of the largest European manufacturers of passive and electromechanical components. The range is really wide, judge for yourself. Let us mention at least two types from a wide range: WE-PD – is a popular “standard” series of SMD inductors. Also available with white coating in the sizes 7332 (7,3×7,3×3,2mm), 7345, 1260 […]

Horacio Bouzas published a 4 way WiFi antenna switch: I started playing with electronics back when I was 10 years old in Argentina, where I grew up. Then I got my ham radio operator license when I was 16 years old and I was very active in the ham club and on the air. It […]
Digital Hearing Aid using MKL02Z16VFG4
https://www.electronics-lab.com/digital-hearing-aid-using-mkl02z16vfg4/
A hearing aid is a small electronic device worn in or behind the ear that amplifies incoming sounds to help people with hearing impairment. This design features a light and compact hearing aid with a soft touch sensor that allows the user to control the volume and frequency depending on the user’s preference. This design […]
Colour Injector lamp
https://www.electronics-lab.com/colour-injector-lamp/
by Taras Sgibnev: The colour of light emitted by this lamp can be controlled using syringes filled with red, green and blue ink. Russian designer Taras Sgibnev developed the interactive product as a physical expression of the way red, green and blue light are used in digital interfaces to create a full spectrum of different hues. […]
Damp-Pi – Room Moisture Extraction with Raspberry Pi
https://www.electronics-lab.com/damp-pi-room-moisture-extraction-with-raspberry-pi/
by davidhunt.ie : Over the last while I’ve been having a problem with excess humidity in the shower rooms. Imagine that, the builder never put in extractor fans when the house was built! Anyway, I could put in those fancy extractor fans with the built in timers or humidity sensors, but I decided to do things […]
Arduino Email Sender with Ethernet adapter/shield
https://www.electronics-lab.com/arduino-email-sender-with-ethernet-adaptershield/
by Matej Blagšič @ instructables.com: My father asked me to do a little project with Arduino that would send an e-mail when a push button is pressed or anything, can be based on temperature reading, so make sure you watch my previous instructable on that or to send that something has closed up on the distance […]

100V, 1A, synchronous step-down regulator: Iq of 7µA
https://www.electronics-lab.com/100v-1a-synchronous-step-down-regulator-iq-of-7%c2%b5a/
by Graham Prophet @ edn-europe.com: LT8631 is a 1A, 100V-input-capable synchronous step-down switching regulator. Synchronous rectification delivers efficiency as high as 90% while Burst Mode operation keeps quiescent current under 7µA in no-load standby conditions. Its 3V to 100V input voltage range suits it for 48V automotive systems, dual battery transportation, industrial and 36V to 72V […]
Tutorial on the Design & Implementation of an FPGA RGB LED Matrix Driver
https://www.electronics-lab.com/tutorial-on-the-design-implementation-of-an-fpga-rgb-led-matrix-driver/
In this episode Shahriar and Timo demonstrate the design methodology of an FPGA based 32×32 RGB LED matrix driver. Timo has kindly devoted some of his time to describe the block diagram and the thought process which goes into designing this type of FPGA display driver. The various components of the overall system (PLL, UART, […]
