Generation of Sound Using Microcontroller
https://www.electronics-lab.com/generation-of-sound-using-microcontroller/
This project illustrates the use of a microcontroller(MCU) to generate different types of sound. The device uses SST89E54RDA-40-C-PIEMCU, an 8-bit 8051-compatible MCU with embedded SuperFlash memory.The device comes with 24/40KByte of on-chip flash EEPROM program memory which is partitioned into two independent program memory blocks. The primary block 0 occupies 16/32KByte of internal program memory […]
Orange Pi undercuts Raspberry Pi
https://www.electronics-lab.com/orange-pi-undercuts-raspberry-pi/
by Martin Cooke @ elektormagazine.com: Over the last few months the Asian manufacturer Shenzhen Xunlong Software has released a number of capable open-spec single board computers with the ‘Orange Pi’ label that are both Linux and Android-ready. Their latest offering is the Orange Pi PC which packs an Allwinner (Cortex-A7) quad-core H3 SoC running at 1.6 […]
4×1 WiFi Wireless Antenna Switch
https://www.electronics-lab.com/project/4x1-wifi-wireless-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 was then when I built my first vacuum tube […]
VHF-UHF RF Sniffer
https://www.electronics-lab.com/vhf-uhf-rf-sniffer/
by simpletronic @ instructables.com This is a multi-chapter instructable. I will be describing the making of a short/medium range RF remote-control using the UHF 433Mhz frequency. It´s impossible to setup & adjust a RF transmit-receive link if you are not sure the transmitter is working properly.At 433MHz, your multimeter or even a regular oscilloscope are […]
SiC/GaN Poised for Power
https://www.electronics-lab.com/sicgan-poised-for-power/
by R. Colin Johnson @ eetimes.com: PORTLAND, Ore.—Today Yole Development predicted that power transistors would radically shift from silicon wafers to silicon carbide (SiC) and gallium nitride (GaN) substrates—to achieve higher power in smaller spaces, according to its GaN and SiC Devices for Power Electronics Applications report. One of the big drivers behind the shift is the […]
Simple Infrared PWM on Arduino, Part 3
https://www.electronics-lab.com/simple-infrared-pwm-on-arduino-part-3/
The crew from AnalysIR has written up an article on Simple Infrared PWM on Arduino. If you missed part 1 and part 2, be sure to check it out.: In Part 1 of this series, we demonstrated how to send signals using soft or Simple Infrared PWM on Arduino. In our Part 2 post we […]

UT602 – for those who are interested in miliOhms
https://www.electronics-lab.com/ut602-for-those-who-are-interested-in-miliohms/
We have for you a measuring device able to measure even small resistance with 0.01 Ohm resolution. UT602 is exactly that device, which you may have missed at development of devices operating with higher currents, where every resistance (lead, connector, joint,…) acts negatively, as well in applications using small resistors (shunts for current measuring and […]
89S52 Thermistor Thermometer: LCD version
https://www.electronics-lab.com/89s52-thermistor-thermometer-lcd-version/
by Wichit Sirichote: This is the 2nd version of Thermistor Thermometer Project done by another group of my student. The 1st version having 4-digit 7-segment LED shows the use of simple display device. For applications that needs text display, this LCD version is more suitable and easy to adapt for many kinds of measuring devices. 89S52 […]
