Dave Jones of EEVblog looks at a sub-3-cent microcontroller from Padauk and other obscure Chinese manufacturers. He shows how to find such parts and where to buy them in stock.

Tech Ingredients demonstrates how microwaves work and how they affect objects at range, then shows ways to defend against them. It includes a correction about rectifier output frequency.

Branch Education's animated deep dive into ASML's EUV photolithography machine and how it prints nanometer-scale transistors onto chips. It covers the system's components and the process of chip manufacturing.

Branch Education walks through a semiconductor fab and the dozens of steps used to turn silicon wafers into microchips, with 3D animation. It covers lithography, deposition and etching at a high level.

Isaac Arthur explores space-based solar power, in which satellites beam energy down via microwaves to rectennas on Earth. He discusses feasibility, profitability and its role in spurring space colonization.
