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...

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 looked at...

89C2051 Development Stick kit offers an easy way of interfacing 89C2051 compatible MCU’s. Slim design with plug in type approach Voltage regulator on board for stable and regulated supply to the MCU RESET switch for resetting the MCU 0592 MHz Crystal 4K external...

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,...

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...

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...

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...

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...
