Post yours on alt.binaries.schematics.electronic ...

I don't really have a full schematic, the majority of the circuit is
identical to the schematic I posted in my own thread looking for some
help. The subject line is "Need help with op-am/comparator circuit" and
the group is sci.electronics.basics. And like I said, it's virtually
identical to the one in the PDF except I had an LCD.
The above link does not have the source code in the pdf with the
schematic. In my opinion, it is incomplete without the code. A hex
file would be nice too so that no compiler is needed.

It was just a tinker toy project, but I could probably dig up the code.
The HEX file wouldn't really be helpfull without an exact schematic of
my circuitry. Besides, it's not a finished product anyway, just a proof
of concept demo. It prints a "P" on the LCD indicating an outgoing
ping, it then just displays the high portion of TMR1 for all the echos
captured, which is a rough estimation of feet to target.

Very likely, and more than you imagine just now.

I would ask, (rhetorically), what do you hope to learn? You
appear to already understand the most basic idea of sonar
range measurement. Do you hope to go beyond that? If so,
you would do well to at least understand how the above two
principles apply to the problem.

I meant that I want to learn about electronics. Interfacing with
different parts, blowing stuff up, etc. Practice/experience is the best
way to learn. If everything works as I expect it to, great, but usually,
it doesn't, and obstacles means learning :)
