want to build a cw keyer for beacon project will these pic (s) work

[KJ4VYI]

Hello all -- I have the following pic chips and want to know which one would be better for a cw keyer for my beacon project ( will need to be a + 12v output key )

here are the chips i have

1 - pic18f252-1/sp
3 - pic16f84a-04/p
1 - 12c508a 041/p3ft

I have come across some projects that use the 16f84 chip but what do i need to program it -- any one out there used this for a beacon keyer and could burn the chip for a trade of one of the chips!!

thanks for the help

Chad, you need to pull the specification sheets for each chip to see if it has the input/outputs kehat you need. If you are just going to do a basic beacon (and not going to transmit all of Shakespeare) then any 8k or better memory should be fine.

Are you going to write the code or are you expecting the same person to burn the chip to also code? If you are going to learn to code this you might as well get a burner. Depending on the chip, there are economical was to program them. You don't have to spend hundreds of dollars for one.

good luck!

I want to build a CW keyer for beacon project will the PIC(s) I have work?

I have come across some CW keyer projects that use the 16F84 chip.
What do i need to program it ??
Anyone out there use this PIC for a beacon keyer?
Could they burn this chip, for a trade of one of the chips!!

Chad -

I would be best if you were specific ... What CW keyer project? Provided by who (commercial, radio amateur)?

PICs are relatively inexpensive, and are equivalent to a black sheet of paper.
K1EL sells many of his chips -- for less $$ than it would take to mail (2 way postage) the chip for programming.

Best analogy --
You have blank copper-clad board and desire for someone to etch / drill the board with your desired project.

You would be BEST served finding a local Elmer who has the PIC tools for programming and testing the PIC.
I have completed a couple of projects with this approach -- but only when the project author has offered
this progamming to amateurs and a small fee is paid for postage and the service.

Steve Elliott, K1EL provides FREE source code for many PIC projects.
Since he has released this software in the Public Domain -- he is unable to provide support for it.

BTW, The ARRL offers a PIC Programming for Beginners publication and supporting tool-kit for the
growing area of micro-controllers.

Make that design, etch and drill

There are tons of fascinating things that you can do with PIC's. With the effort needed to code and program... I'd think that building a simple beacon isn't one of them.
