Thanks for the reply. I guess I am the type of person that wants it now. I
think back to my computer experience and it was a long hard road of
learning. took years and years. I assume the same would be true for
electronics. as a matter of fact I took an electronics course in school,
back in the day around 1981. That is when I decided that I would rather get
into computers. Working the end result of the electronics rather than the
electronics themselves. I guess a lot has changed since 1981. I still
remember ohms law and how to calculate resistance run in parellel. I realize
that this is a rather large project as I am jumping right into digital
electronics, but for someone with my very rudimentary knowledge, wouldnt it
take years of study to come up to speed to tackle something like this? This
project is just like me, jumping in with both feet. I was going over the
posts in the group and could follow alot of it. Like the discussing about
the LED's and the difference between running them in parellel with there own
resistors as opposed to running them in sieries with one resistor. And then
there where other discussions that I was just clueless about with no frame
of reference. As for the cost of the project, I feel that it could "pay for
itself" by being able to reprogram the chip on my own rather than paying
someone else 45.00 everytime I needed it reprogrammed. As far as "not caring
why it works" I guess that is not necessarally true. Its just that the time
I think that it would take to increase my knowedge to the point where I
could design something like this would take years, not weeks or even months.
I am still interested in doing the project but have no idea even where to
get started. I have no idea of what parts are availble. What type of memory
chip i would use to store my sound byte, etc. I guess I could get some parts
from Radio Shack, but only the very basic ones. (I used to work there so I
have a good idea of their inventory). I have seen these types of devices in
CB Shops and on the bread boards that they use it only appears to be a few
parts, so i do not see cost as a real big issue (at least not for the final
cost. I do see how testing and trial and error could get expensive) but of
course the design is of a closely guarded secret as they want to keep
getting their 45.00. Cant say as I blame them, they have to eat too. Well I
have gone on enough here. If you have any suggestions as to where to get
started, please let me know.
Thanks,
Scott
