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.

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

OK, so I have an old project laptop with an IDE/PATA/slim-ATAPI optical drive bay, into which I have inserted a SATA drive caddy with a bridge board. The thing is, the caddy doesn't transfer the drive ...

With just three transistors, one relay, and some resistors and capacitors, a single light switch can provide sophisticated control of high-power and low-power lamps. With just three transistors, one ...
