As most electronic engineers and hobbyists do, I have a great respect for the earlier ways of controlling electrons, before it was found out that silicon could be used to miniaturize everything a thousandfold. It is amazing that things like a vacuum, a glow wire and a bunch of strange-looking metal bits can actually do […]

The GS66540C (the picture is of a prior, lower-current part) high current power devices will be revealed for the first time. Part of the company’s family of 650V gallium nitride power transistors based on its proprietary Island Technology, these high density devices achieve extremely efficient power conversion with fast switching rates of >100V/nsec and ultra-low
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
Not long ago, I reached 50 000 views on my ESP8266 Wi-fi module. I was quite amazed and wanted to thank everybody that watched it, liked it and commented on it. On September 2., I published instructable on Weather station and got featured only 15 min after publish. I was very motivated to do more

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 electric vehicle (EV) and
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 sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal using soft PWM. We have since improved the PWM
Simple Infrared PWM on Arduino, Part 3 – Hex IR Signals Continue Reading

This is a library for interfacing with the HID features of the MCP2221 USB to UART and I2C/SMBus serial converter from Microchip. The converter includes 4 GPIO pins, 3x 10-bit ADCs, 1x 5-bit DAC and more. Microchip does provide a library for interfacing with the chip, however it is supplied as proprietary DLLs. This project
