Arduino Nano ESP32 becomes an ultra-low-powered, pocket-sized Linux PC
Reading Time: 2 minutesWhile many users get them confused, microcontroller development boards and single-board computers are very different things. Single-board computers can run full operating systems, like your desktop PC or laptop does. Microcontroller development boards, like those from Arduino, are usually limited to simpler firmware. But as microcontrollers become more powerful, the line gets…

A DIY tube furnace for creating ICs
Reading Time: 2 minutesModern integrated circuit (IC) chips can have transistors as small as two nanometers, which is only about 10 silicon atoms laid end-to-end. At that scale, fabrication looks more like chemistry than any kind of physical manipulation — a machinist isn’t carving tiny transistors into silicon wafers. For many types semiconductors, the fabrication…
