This article is a preview from my upcoming course on filters. I use real experiments and simple explanations to make the concepts accessible, whether you’re just starting out or looking to refresh your skills.

New blog post: I explore the impulse response of first-order filters, with a full lecture video included. See how low-pass and high-pass filters react to sharp signals, and learn how to analyze their behavior in your own circuits.

I’m designing a hands-on course on RC and RL filters β€” Python, CircuitLab, real circuits, and the Analog Discovery 3.

What would you like to see in it? A specific circuit? More audio examples?

πŸ’¬ Let me know below or on the blog.

Arduino's first AI board β€” the Uno Q. Dual-brain architecture: Qualcomm AI processor + STM32 microcontroller in the classic UNO form factor.

I tested it.

Here's my honest review + 10-min video:

I spoke at KiCon Asia 2025 in Shenzhen about something I'm passionate about: eliminating "learning debt" in electronics education.
KiCad is the only PCB tool you can learn once and use for lifeβ€”from student projects to commercial products. What do you think?
