Dude you are the life saver to me… i needed a small project on 55 timer…this really helped me a lot…excellent work…
Thanx a lot….. A great help to a poor fellow….
Owsum ! Hats off ,,,,,,,,,,,,,,,,,,
hello.may I ask why the circuit of the first one didn’t work?I created a pcb design of it and now I don’t know how to troubleshoot it. By the way, I used a 8ohm,5watts speaker and the battery is 8 volts.thanks.
did you test it on breadboard before you made on PCB? If it works on breadboard, then it should work on PCB also.
dude, can u tell me about its applications???
hello i want ask you can not use the ceramic capacitor ? any way why were u used 9v to the supply? thanks
Is there a substitute I can use for the 33 micro farad capacitor? I only have 22 or 47 micro farads.
can u list the component parts of this circuits? thanks…
