Dazer question

Looking at this:
**broken link removed**

i am confused on the oscillator side of the circuit....

seems as though Q2 is backwards??

can someone write a brief description on how that oscillator works? i've made oscillators with 2x NPN transistors, but not a PNP and an NPN.

Hey,

Check out this page for pretty much the same circuit.. It is around 1/2 way down or less.. There is a full description

haha thanks, now your post makes more sense. i was like "wow he didn't have to be so mean" hehe

ok so still to my main concern, i understand how Q1 turns on (the NPN) but i dont understand how that action turns on Q2 (the PNP)

....

any hints?
