This circuit, as shown in schematic, seems to work pretty well, but I'm sure that there are lots of ways I could improve it's efficiency.
I'd like to avoid ICs if I can, but if you can suggest better resistor values, etc I would be very grateful for the guidance. I have one typo in the schematic, the 100K resistor is actually more like 1000K.
I have no idea what the 8Ω resistor does for it, but the circuit doesn't seem to work right without it. Any explanation for why this is would also be much appreciated.
Please excuse my crude design, I don't have any formal training in electronic design.
