A Visual MIPS R2000 Processor Simulator – Freeware

ProcessorSim allows you to view a simulation of a processor’s internal circuits (components and buses) executing a piece of assembly code, as an animation. It is mainly used for learning how the processor works, and so is useful for undergraduates in Computer Science, or anyone who is interested in how CPUs work. You can input […]

USB LED Lamp Circuit

Description. Here is a simple USB powered lamp that can be used to light your desktop during power failures. The circuit operates from the 5 Volt available from the USB port.The 5V from the USB port is passed through current limiting resistor R2 and transistor Q1. The base of transistor Q1 is grounded via R1 which provides a constant […]
