hey guys....i wanted to ask...where do i find a basic led circuit...i dont need any flashing type or watsoever....just a plain led circuit...got 2 criteria

1. the led must remain lit without blinking or anything else
2. i'm using alot of leds...nearly 100 of em...so is there any way to connect to
a 240v power supply cause i think battery not enough to keep it lit for long ...its something like christmas lights

Hey guys, I'm building a very simple dc generator. However the voltage output is too low, below 200mV. How do I increase this to light up an led?
