Here's a source of power I bet you didn't know existed. A 7-segment display can power your devices!
Here's how to work it. Flip the switch to the up position. The display will turn ON. Now, flip it back down. Even though the current is disconnected and the display turns OFF, the LED magically turns ON! Look closely, and you will see current flowing OUT of the 7-segment displays INput pins! What on earth?
The secret lies in hidden capacitors inside the 7-segment display. When the switch is up, the current will flow through the display, causing it to light up and charge its capacitors. Then, when the switch is flipped down, the capacitors discharge their stored energy through the LED, making it light up.
Obviously, this is totally impractical, but it is a fun little trick in the simulation. Maybe show it off to a friend who isn't familiar with it. He'll think you're a wizz!

Did you know this same sort of thing can be done with an LED? https://everycircuit.com/circuit/6130917080563712
