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 […]
Power supply IC generates low-noise bipolar (+/-) power rails
https://www.electronics-lab.com/power-supply-ic-generates-low-noise-bipolar-power-rails/
by Graham Prophet @ edn-europe.com: LTC3265 is a high voltage, highly integrated, low noise dual output power supply IC which takes a single positive input supply (VIN_P) and generates low noise bipolar rails up to ±2•VIN_P without any inductors. High voltage boost and inverting charge pumps deliver low noise dual outputs with post-regulating ±50 mA LDOs […]
Delay using 8051 Timer
https://www.electronics-lab.com/delay-using-8051-timer/
The major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate time delay. The light emitting diode (LED) is connected through the 330Ω resistor to indicate the time delay. The blinking LED switches ON for 1ms and switches […]
IC monitors multicell battery packs
https://www.electronics-lab.com/ic-monitors-multicell-battery-packs/
by Susan Nordyk @ edn.com: The ISL94203 battery-pack monitor IC from Intersil monitors, protects, and cell-balances three- to eight-cell rechargeable battery packs, supporting Li-ion CoO2, Li-ion Mn2O4, and Li-ion FePO4 chemistries. Its internal state machine has five preprogrammed stages that accurately control each cell of a battery pack to extend operating life. In addition to […]
