🔧 Featured Project
A maker has built a hydropower generation circuit that generates power from a water pipe in a building using a microturbine, with the generated electricity used to charge batteries for emergency lighting or other purposes.
Based on the amount of water flow in the pipe, the power generated using the turbine can be varied.
Perfect for overhead water tanks flowing to ground-level taps.

🔌 Component of the Week: MOSFET
The Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is the workhorse of modern electronics. Unlike bipolar junction transistors, MOSFETs are voltage-controlled devices requiring virtually no gate current, making them incredibly efficient switches. They come in two flavors: N-channel (conducts when gate voltage is high) and P-channel (conducts when gate voltage is low). MOSFETs excel in power applications because of their low on-resistance and fast switching speeds. You’ll find them controlling motors, switching power supplies, and even inside every microprocessor. Key specs to watch: gate threshold voltage (VGS), drain-source on-resistance (RDS(on)), and maximum drain current. Choose wisely and these three-terminal marvels will switch kiloamps without breaking a sweat.
