Depends what you want. I’d go with a microcontroller for starts so you can change it programmatically. I’d bet someone has done it with an Arduino or Pi. Here are some links to interesting looking projects. Those circuits operate mostly at safe low voltages and control low power LEDs. The same ideas can be used →
There are now Arduino simulators for what you will just need a web browser you’re good to go. Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for various Arduino boards like Arduino UNO R3, MEGA1280, →

An ideal power inverter will produce same kind of power that is available from mains outlet, which typically means sine waveform 60 Hz 11-120V AC or 50 Hz 220-240V AC. That kind of power source can power all mains powered devices as long as enough power is available. Where power inverter devices substitute for standard →
