hello all
very unfortunate for :( i spent almost i week trying to design the circuit i downloaded from this site call time beeper and it didn't work. can any
help me out ::) cos am down
hi i'm binkabir, i think we can makes thing better by use a common collect configuration of a transistor insteaded of the bulky transformer, all you need to do is to find the transistor that can work with that current and voltage at the output , this is easier cheaper and less bulky. ;D
i can answer the second question on parallel regulators: actually i can used them as you said but i will be wise if add a voltage double after each regulator. but that i not a good design technique. :-[
preferable you can use a power amplifier to increase the current gain and a buffer to...
that's true but when you are looking for an advancment in terms of functionality
and efficency 555 should be counted out. do you know the you can make 4060 an
have 7 output with different ocsillating frequencies whereas the 555 can only utilize
just one.
i have used both the 555 and the hcc4060b in designing of circuit and i found out that 555 is an out dated ic that really need not to be used EXCEPT FOR NEWBIE IN ELECTRONICS
