a transistor simulator and learning tool for students, hobbyists, and anyone studying electronics. SIMULATOR Adjust supply voltage, input voltage, base/collector resistors, and gain with real-time sliders. The circuit solver computes operating point, currents, voltages, power dissipation, and junction temperature as you move each slider. Supports 12 device types: NPN, PNP, Darlington, N/P-enhancement MOSFET, N/P-depletion MOSFET, N/P-channel JFET, IGBT, phototransistor, and UJT. The display shows which region the device is in — cutoff, active, or saturation. BREADBOARD A pre-wired LED switch … Continue reading “Transistor Simulator App”

A color-based logic puzzle game. Fill every cell in the grid with blue or red while following three simple rules: The Rules:• Balance — Each row and column must have an equal number of blue and red cells. Some cells include number clues that tell you how many neighboring cells share the same color, giving you a starting point to work from. What’s Included:• 350 handcrafted levels across three difficulty modes (Easy, Intermediate, Hard) • Grid sizes range from 4×4 … Continue reading “Color Logic Grid”
