This power inverter uses only 9 electronic components. This inverter circuit will turn 10 to 16VDC into 115V / 60Hz square wave AC power. It was able to operate AC equipment up to 25W.
The first section of the 555 timer is wires as an astable oscillator with R2 and C1 setting the frequency. The output is available at pin 5. The second section is wired as a phase inverter. That output is available at pin 9. Resistor R3 and R4 keep output transistor Q1 and Q2 from loading down the oscillator.

I’m teaching myself how to create electronic circuits and electronics in general. Basically, I want to be able to intelligently fiddle with small circuit boards for some halloween anamotronic figures that have blown circuits. Spent a lot of money on these things and want to be able to fix them.

This is a high quality audio class AB amplifier in hi-fi applications. It has very low noise and distortion, wide bandwidth and good output current capability, enabling it to supply high power into both 4Ω and 8Ω loads. It has both short circuit and thermal protection, so is quite robust.
