A very cool (also warm!) property of the base-emitter junction of (most) small signal BJTs is the ΔVbe temperature-sensing ...

There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, ...

In this video, I explore the new Arduino Uno Q and its impressive possibilities. The project covers initial setup, coding ...

On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the transistor age and the era of modern computing. When you purchase through ...

A Planet Analog article, “2N3904: Why use a 60-year-old transistor?” by Bill Schweber, inspired some interest in this old transistor and how it’s commonly used, and if any uncommon uses might exist.

Abstract: Vertical silicon nanowire transistors are among the most promising device concepts for future low-power electronics due to their gate-all-around nature as well as their 3D stacking potential ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Researchers at the Institute of Industrial Science (IIS) at the University of Tokyo in Japan have built tiny transistors that do not use silicon. Instead, the team doped gallium into indium oxide and ...

M5Stack’s Unit Gateway H2 is a small Thread/Zigbee gateway powered by the ESP32-H2-MINI-1 module with an 802.15.4 radio for Zigbee 3.0, Thread 1.3, and Matter connectivity. The Unit Gateway H2, also ...

Run in the Arduino IDE the HelloWorld example with an ili9488 in SPI. In fact, you don't need an ili display to try this, because it fails at compile time. The possible wiring errors, are irrelevant ...
