@Num7 : I read a document says you do not need the exact buzzer..I hope this helps
I'll keep you updated when I work on it again. It's been a few years since I didn't take it back of its box.
the tto and tec schematics are the same
Yup, Steve is right
That's right, didn't notice. I merged both threads.
Thanks for the heads up.
what buzzer if your refering to the same 15000hz pezio buzzer used in the bajak capacitor its dosent have a biult in driver circuit and ive never been able to find one listed on some page where the buzzer details was on it just said it dosent have a driver you can get it and it wasent even listed on the same site for it to look at the details
This circuit drives any wafer buzzer..I tried it it works
R1 = 100K,
R2 = 4k7,
T1 = BC547,
L1 = Buzzer inductor,
PZ1 = Piezo element, 27mm, three terminal
ive got heaps of buzzers from e bay they all 2 terminal ones so where did you get a 3 terminal buzzer from
got them from dead microwave oven. a gold mine indeed...U also get it from dead washing machine upper bord.
