Inside the NE555 astable multivibrator 25% duty cycle. With this you can find how an NE555 works. Enjoy it. Remember to open the switch to see the circuit working, remember also to close it before saving to avoid the "cannot find solution" error.

Again I had to turn your circuit so I could see what was happening, even then it took me a while to see what was happening with the diode. http://everycircuit.com/circuit/5474646423502848

This circuit is optimized for my teaching course.The circuit is more close to the original 555IC pin numbers.
