Welcome to Circuitry - the world's first and only 3D circuit builder! INSANELY FAST Circuitry uses an optimized, GPU-accelerated network analysis algorithm that will blow your mind. It can calculate the voltages and currents of even the largest circuits in the blink of an eye - an insanely fast blinking eye! SUPER DUPER EASY TO USE While most circuit simulators are stuck in the stone age when it comes to usability, Circuitry takes you on a time-travel journey to the future. Its' 3D interface and intuitive controls will instantly feel familiar - no lengthy tutorials required. DOCUMENT-BASED Every circuit you build in Circuitry is a file. That way, they integrate perfectly into your existing files and can be used exactly the same way: you can duplicate and modify them, share them, and they are available to you on all your devices. HOW TO USE: 1. Place components by dragging from the toolkit to the canvas. 2. Connect components by tapping the sides of the components in cabling mode. 3. Delete or modify components by long pressing on them. AVAILABLE COMPONENTS: - Resistor - Voltage source - Light bulb
