Update: For my non-engineer friends, a 555 is a “timer” chip that turns on and off. You can program how fast it turns on and off with a few resistors and a capacitor. I figured out how to make it turn… half on and half off at the same time. I did this by putting a really fast chip in front of it that turns the 555 on and off so fast that it stays half on. And actually I can turn it 1/3rd on or 3/5ths on or any fractional voltage.
This has no usefulness or practical functionality whatsoever.
