Re: TI-H: RF link idea again
[Prev][Next][Index][Thread]
Yes, RF is a definite advantage especially if you can just hook up the calc
with a 6ft long cable to the com unit in your bag or pocket or something.
No one would know; only those that are bright enough.

: Me again with some more q/c's about my proposed RF link.
:
: I'll be getting very shortly a schematic for a cheap RF transmitter.
: (Thanks, CJ Oster!) I need someone to tell me how to make an RF receiver.
: Something with a coil and diode. (?) The coil tunes, but how? I'll need
: schematics for that. A WWW site would be appreciated for a GIF. TI's send
: and receive on different wires accross a link, so for RF, two differnt
: frequencies would be needed. When i slice my link, which wire sends and
: which receives? and what is the other one for? What frequencies will get
: the laes intreference? I want to stay off of the standard radio bands,
: probably below, because (i think?) above is police and whatnot. Am I
right?
: Should I try AM or FM?
:
: All help will be greatfully acccepted in hopes of completing this project
: one day.
: Thanks again, Travis
:
: P.S. I'm in favor of RF over IR because of this one reason: IR has to
have
: a clear path between the sender and receiver. RF can go through concrete
: walls. A definite advantage,
