Beginner’s Corner: Inductors in DC Circuits
Introduction In this installment we examine inductors (also called coils) and their behavior in DC circuits. We'll look at what they are, what they do, and how they respond in both steady state and transient conditions (i.e. a state change). In addition to the theory, we'll spend some time in the lab looking at real-world … Continue reading Beginner’s Corner: Inductors in DC Circuits
Embedded Topics: Digital to Analog Converters
In this installment we look at Digital to Analog Converters (DACs) in general, and the MCP4725 (12-Bit, I2C) specifically including how to hook it up to a microcontroller and control it through software via the I2C bus. We'll look at in theory and in practice in the lab. https://youtu.be/JfH9Rj3zpbM If you enjoyed that, and learned … Continue reading Embedded Topics: Digital to Analog Converters

Put a Raspberry Pi 3 Model B in a Mini Tower Case
I love my Raspberry Pi 3 both as a Linux desktop machine and as a Commodore Amiga Emulator (especially classic games like “The Secret of Monkey Island”) but I’ve always found it a bit annoying to have it sliding around my desk every time I move a cable. When I saw a Rosewill mini tower … Continue reading Put a Raspberry Pi 3 Model B in a Mini Tower Case
