I don't remember, that was a circuit I built only to test that 2N2222A configuration, with "many" LEDs... Anyway, it's the common astable NE555 scheme, so look for it on Google.
i'm a noob of all noobs! But i have a question! I hooked up a 12 volt battery to a tlc555 timer and cooked it???? WHY??? The technical data says up to 18v ....i'm thinking i need a resistor on the positive side...oh let me tell u it got bright white and went POP
It's possible! Be careful with power sources and output pins, because they might make short circuits! To avoid it, put a series resistor with a reasonable value, in order to keep the current in the operating range (you must learn how to read datasheets, because they're the "Bible" of electronics projects!).
lol i just blew up a TLC555, i think it overheated from sinking. i need to isolate it from my mosfet or play with some diodes lol. but when i say it blew up, i literally mean it haha the top half flew to the ceiling and there was a small fire. scary! i think i'm gonna wear safety goggles from now on when trying these out.
what duty cycle are you adjusting it between? and does the frequency stay the same?

the tlc555 is a low power version and can get fried easily

It happened to my high school professor too: a '741 blew up while checking breadboard wirings :D
I might still have the small (< 1mm x 1mm!) silicon chip in my pencil case.
